October/November 2003 – Primer, block-sanding, coat two

Update: November 12 — It hardly seems worth an additional web page, so I didn’t add yet more pictures of the same old blocking. The focus was on the left door, and I was committed to conquering its waves. The blocking took all of the working weekend, amounting, I would imagine to a good ten-to-twelve hours. I noticed on Bill McKenna’s website that he spent 25 hours on his left door, so I figure that my work is about in line with his. There’s still another coat of primer to go on it, and I don’t know how many hours I spent working on it before this past weekend. As Bill says somewhere on his web site, it’s a wonder that people can actually make money doing a decent restoration. The hours required — and from skilled people, too — are formidable.

Speaking of Bill, I bought a replacement left frame from him. It was good to see his paint job in real life, at least a small portion of it. I’ve not done anything with the frame yet. I figure that can wait until I have the car body primed.

Second Coat of Primer

The car was turned into a pumpkin for Halloween. After the second coat of Tie-Coat Primer was good and dry, I put on another guide coat of flat spray paint. This time I found a half-can of hideous orange. It made the car look like a well ripened pumpkin — appropriate for the season. I took this picture after I happened to see where we were about a year ago. It turns out that we had just applied some POR-15 over the same area of the car after having removed paint. We were still pretty much in a tear-down and clean-up mode back in October-November 2002. It is good to see those old web pages, since it at least gives the impression of progress. Block-sanding tends to throttle that feeling, except of course when you tear into a bright orange marker coat!

It’s probably worth remembering that the point of doing multiple coats of high-build primer isn’t so much to coat the surface evenly with a thick coat. It’s really intended to allow you to even out low areas and obscure high areas, though of these two, I think that high areas are problematic. So in effect, you end up sanding most of the high-build primer off of the car. You leave a reasonable amount of primer on to assure a good bond of the topcoat to the surface. The temptation is to block the car a bit too little, leaving more than is needed to prepare the surface.

I get the feeling that this is really an art. And I also realize that good body work is worth the money people spend for it. It is labor-intensive and experience does count. (Too bad I have so very little experience!)

The second coat pretty clearly tells me that you really can’t spray the final primer coat and expect things to turn out all right. Despite my care while brushing the second primer coat, blocking it was complicated by the fact of the brush strokes. I found myself reblocking sections that had slight ripples from brush strokes, and I believe those areas would have been flat and ready for paint without the brushing. As a matter of fact, I think first coats are fine to brush, but probably not second coats.

For this priming of the car body, I will complete a second coat and second round of blocking the parts of the body that appear “from the curb” — the external sections of the body shell and the bonnet. The internal sections of these parts will get a single brushed primer coat and blocking. This includes the trunk (or boot), the firewall (or front bulkhead), the interior of the car, and the inside of the bonnet. I will probably spray color in the trunk, the interior, and the inside of the bonnet at that point. After all of this is done, I will spray a final coat of Tie-Coat Primer as smoothly as possible over sections of the car that are not already sprayed with color, followed by final blocking of those surfaces.

Of course, I could spray color on everything at once, though I am thinking that I’ll still have to spray color on the bonnet in at least two sessions, since I want to coat the inside of the bonnet thoroughly. This really means that the inside shell without the internal panels will need a separate spray session. The inside panels and the front valance (the lower “mouth” section) can also be painted separately. Once everything is together, another coat of color is in order.

Once again, the bonnet seems the complication.

I avoided doing the doors until I feel confident that I have a few more blocking tricks in my repertoire. I applied a bit more primer to a couple of low areas on the rear wings, and blocked them nicely into shape. Perhaps that tactic might help should I run into some irregularlities on the doors. I think that the doors are challenging because they don’t have the curves of the wings and the rest of the body. They are almost a pure tubular shape, and it seems difficult to get them just right. I also primed the trunk lid.

A couple of closing shots show where the blocking stands at the end of the weekend.

October 2003 – Paint-primer-with-a-brush hypothesis tested

Paint-primer-with-a-brush hypothesis tested

I mentioned at the close of the last entry that I was going to test out whether “high-build” primer could be painted on with a brush and still have it serve its purpose. Well, I didn’t use a typical sprayed “high-build” primer, though I used a “sandable/buildable primer.” The coating is “Tie-Coat Primer” that I needed to use to bond coatings to POR-15. POR-15 is very tough, and it has properties that make it tough to get regular primers to bond to it. Basically, you have to sand the surface rough in order to get primers or paints to stick to it. Or, you use Tie-Coat Primer.

I applied the Tie-Coat to the bonnet nose, which needed some smoothing in any case. I put on two coats, and after they had set I sprayed a thin coat of regular old flat black paint. The black paint was the “guide” coat that would mark where I had sanded and would highlight low areas on the surface. if the test worked the sanding after this initial primer would leave a perfectly smooth surface, leaving slightly rough and darker patches where low areas would be. High areas would become the color of the underlying POR-15, since the primer would be entirely removed with sanding. Only block sanding is allowed at this point. Taking some wet sandpaper in hand and trying it out with your fingertips just leaves grooves and usually frustrates the purpose of the marker paint coat, since your fingertips just follow the surface, however rough, and take off the paint.

The picture of the bonnet nose shows the light black marker paint over the buildable primer and the block-sanded surface. The bonnet, you might recall, has been a real challenge, and the marks show it. These marks are mostly well defined notches where body filler wasn’t adequately applied. Most low areas end up looking like shadows where wider, less detectable, depressions lurk.

I’m happy to report that the paint-primer-with-a-brush hypothesis tested out just fine. However, I do think there is a bit more waste of primer, and perhaps coats need to be applied a bit more thickly. This is because you have to sand through the brush marks, which appear quite clearly after the first swipes of the block over the surface. There also may be a bit of a tendency to remove too much primer in certain areas in order to remove brush marks. My suggestion is to remember to use reasonably long swipes of the block and avoid concentrating effort in any area. If you are using anything shorter than a 20-30 centimeter (about a foot) stroke with the block, you are probably going too hard at an area. If you use a small block to get at tighter areas or corners, be extra careful.

Because of the brush marks, I’m a little suspicious about applying final primer coats with a brush. It might be counter-productive, though I am going to see whether it’s possible by watching this project. I do think that brushing at least an initial coat makes good sense, and it probably can allow people to avoid a mess with sprayers.

A footnote: I was originally thinking that I would use Tie-Coat to prepare the surface to accept another high-build primer, but I learned from the POR-15 people that they don’t recommend mixing primers like that. They told me in response to an email question that Tie-Coat is a buildable primer and using another primer over it might have unexpected results. They responded quickly, too, I’m happy to report. I don’t know about the response, though, since it might have been designed to drum up more sales of Tie-Coat Primer. I’m not taking any chances, however. I’ll be using Tie-Coat as the one-and-only primer for this project.

Initial brush priming the body shell

After the bonnet experiment tested well, I went ahead and brush primed the body shell first with a thin coat of Tie-Coat Primer and then after it had set overnight a thicker coat — at least a coat that ended up with some drips here and there. After that coat set, I sprayed a dusting of the flat black paint as a marker coating. I made sure that the primer itself had set before I did any block-sanding. (Tie-Coat is supposed to accept topcoats after no less than 24 hours after application.) Since temperatures had been below 60 degrees Fahrenheit (about 15 Celsius), I gave the primer about 48 hours before I tried blocking.

I used 320 grit wet sanding on two different block sizes, a four-incher and a nine-incher. The smaller of the two worked very well on the rear upper quarter panels (the “humps” to each side of the trunk space over the rear wheels). The larger block worked merely acceptably on the larger flat areas on the sides and forward on the body shell. I say acceptably, since the right door gave me a fair amount of trouble. I had built up the rear lower section of the door so that it met the door frame, and I expected that there would be irregularlities that would come through in the marker paint. Oddly enough, the door blocked to a light blue, practically without a bit of marking paint appearing, even though irregularlities were quite easy to feel, and pretty easy to see when the piece was cleaned and shiny with water.

I should add that the “Carolina Blue” color of the primer was not my choice. That’s apparently the only color Tie-Coat comes in, or I would have chosen something else! This is the only time this car will appear light blue, at least as long as I own it.

But, back to the block issue. I didn’t want to use the longer home-made block, since it lacks the soft covering behind the sandpaper, and I didn’t want to gouge the surface with a slip. I do think that either I need to get better with the nine-inch block, or I need to find a much longer block to do the sides. I’ve noticed that the body folks at Classic Jaguar have a huge block with two handles on it to do the side panel and door work. The flat surface of that block must be about a meter long, since it easily straddles the length of the door and overlaps well over the ends of the door frame. A good long block would come in handy when you block up the body shell, the outer sills and the bonnet, I suppose.

Block sanding is not very interesting, though it does have some rules. First, keep the block parallel to the line of contact. In other words, if you are block-sanding a curved surface, the contact points of the surface should be a consistent line from the front to the back of the block. Second, move the block diagonally across the surface, first in one diagonal and then after you cover the surface, along the opposite diagonal. In effect, you make an “X” shape with the directions of your sanding over the surface. Third, thoroughly block the surface, but don’t dwell on any one place too long. With “high-build” primers, it’s pretty easy to oversand an area. And, fourth, use the block, not your hands. You can’t believe how many times you’ll be tempted to “touch” up an area with your fingertips. You can’t believe how many times you’ll screw it up. If you can’t resist the urge, use very, very, very light pressure with your fingertips, and don’t dwell on a specific area. I’ve found that even trying to rub down drips of the brushed primer with fingertips is counterproductive. The block is much better. You’ll need to keep the block quite wet, too. The primer soon turns into a gooey lubricant if you don’t rinse it off. I used warm water with just a few drops of dishwashing soap. The soap seemed to help keep the sandpaper clear, and yet there wasn’t so much in the water that soapy film became a problem. An old cake pan worked great as a container. Wipe the blocked surface with a wet cloth to get the sanded primer out of the way.

I got the entire external section of the upper body shell completely block-sanded in about seven hours, I would guess, after subtracting interruptions and breaks. Like I said, this is not very engaging work. It’s repetitive without a doubt.

I checked the surface by wiping it with some low-concentrate soapy water and then looking at the reflection of flood lights along the surface. The lines should be predictable, and you shouldn’t see small wavers (except where you’d be expecting them). The dark picture shows the floods reflecting against the right side of the car. There are some pit-like reflections that come from small soap bubbles. You can see a wavering of the reflection in the door, where irregularities widen the reflection. I usually get a good long reflection in view and then move up and down to see the reflected line travel across the surface. In the case of this side of the car, I should see a consistent line. I didn’t because of irregularities in the door panel. It still needs work. But the rear quarter panel is in pretty good shape.

I also used a little bit of Evercoat “Easy Sand” body filler to bring up a couple of areas on the left side — one flatness over the rear wheel well that I mentioned before and flatness where I repaired the “fillet” some time ago. Very little of the body filler was required. That Evercoat product, by the way, was good to use and seemed to set well. I now wish I had used the Evercoat body fillers from the beginning.

Second coat of primer

I decided to try brushing the second coat of primer. (I’m planning on three coats for external sections of the car.) Instead of applying a coat that would drip, I applied two fairly thin coats, and I’ve applied a third thin coat to areas I think need a little more coverage. I’ll let the primer dry well and apply a marker coat of paint sometime this week. Then it’s back to blocking again. I’m debating what to do about the nine-inch block. Do I try to use it again? Do I look for a longer block? Do I try to make a long block myself?

October 2003 – Color choice, subframe & “boot” primer

Color? It’s going to be British Racing Green

Ah! to fix dents is easy. You see them, you fix them. You know when it’s right. Not so with color. I know that I have driven my family crazy with this decision, and I can’t but help think that even this decision is, well, provisional — at least until the paint sits in a can in the garage.

I know I have felt as committed to

  • Opalescent Silver Blue — too much like Carolina Blue, and I’m a Duke man,
  • Opalescent Dark Blue — Duke blue on a car, but my wife’s truck is the color already and red or dark blue interiors are recommended, and
  • Opalescent Dark Green — great in theory, but the car recently sprayed the color in the Classic Jaguar workshop just didn’t appeal to me.

And British Racing Green is a color with roots. The earliest surviving E-type roadster, if I’m not mistaken, is BRG. It was (and still is) known as 77 RW, restored in 2001. British Racing Green is a good traditional color for British sports cars. So why not have one in rural North Carolina, too?

Centering the bonnet subframe

When we stuck the bonnet on the frames, just to see what the old thing looked like, we noticed that the bonnet was cockeyed. The trouble is in the bonnet frame, which probably sustained some accident damage. (My initial observations, including a description of the way the damage was “repaired” or at least hidden, appear in a previous entry.) What we needed to do was more systematically and geometrically characterize the damage: What was pitched? How much was it off center? Where is the pivot for the pitch to the left side of the car?

The exploration really began with some crude drawings that I made back in August, when we could measure the effect that the frame damage was having on the fit of the bonnet. Those measurements showed that the bonnet was set too far back on the left side — in fact the bonnet was butted against the firewall (front bulkhead) on that side. On the right side of the car, the bonnet was too far forward by about 3 centimeters or so. Drawing out the general structure of the frame identified a couple of places where the pitch to the left could have pivoted. The entire frame structure could be pitched, meaning that the side frames (the “A” shaped structures that make up the engine compartment) could be bent. This would mean that the pivot would be at the center of the firewall. Or, the front frame piece that holds the bonnet and the radiator could be pitched. This would mean that the pivot would be at the center of the so-called “picture frame,” the front of the engine compartment that attaches to the side frames. Clearly, the pivot from the center of the picture frame would be preferable, since a pivot off of the firewall would be virtually irreparable.

I doubted that the damage was off the firewall, since there was no other evidence of damage there. But the side frames themselves could bear the damage in some not-too-apparent way, I thought. The left side frame already concerns me because of the rust damage I discovered on it.

Another thing that helped was a schematic of the body shell and the front frame structure that appears in the Terry’s Jaguar catalogue (“Body Dimensions,” Terry’s Jaguar Parts, 11th ed. [Benton, Illinois, 2001], p. 6-3). The drawing and measurements help to situate the frame structure especially in relation to easily figured out points on the body. The information is for “checking points for accidental damage on [the] XKE body and front frame.” The only thing that might be a bit misleading is the accuracy of the measurements. They are, I believe, too precise, sometimes going to the 32nd of an inch. That kind of accuracy usually isn’t necessary for the body, since fitting sections together often includes bolts and holes that are designed and intended to be used to make minor adjustments to the fit. But this catalogue is a good reference to have on the shelf. Terry’s Jaguar Parts has a good reputation as a parts supplier. They’ll send you a catalogue if you ask.

Using TJP’s “Body Dimensions” as a guide, we strung some string along the center line of the body shell, extending it out into the front frame area. We found that the picture frame hit dead center as it should, but the bonnet frame was off about 2 centimeters to the left. We marked the point where the center line of the car crossed the bonnet frame hinge tube (the forwardmost pipe) and the radiator mount. We measured these points against the centers of the hinge tube and the mount. Then we tied the string to the center of the picture frame and ran the string to the true center of the bonnet frame hinge tube and checked to see where the string crossed the radiator mount. It crossed at the center point of the mount.

That process of string measuring might seem a bit complicated, but it established that the problem with the fitting of the bonnet was entirely in front of the picture frame. The pivot of the bending was at the center of the picture frame. The picture of the frame from the top plainly shows the bend, and now that I see the frame in a photograph I see how rough it looks. So, now I’m wondering about having even this frame repaired. But that brings up another topic….

On not repairing the subframes

A kind email message from fellow E-type restorer Bill McKenna urged me not to have the damaged left frame repaired. The steel (Reynolds 351) was brazed from the factory and is a fairly touchy metal to work with if you don’t want to lose the temper or otherwise weaken the metal. As Bill put it: “To me those frames are all that’s between a nice drive in the country and a major disaster, so not a good thing to skimp on.” Now, I don’t think that the bonnet frame has quite the stress that the other frame parts have to bear. Nor does the bonnet frame quite have as much riding on it in terms of safety. So, I think I could have the bonnet frame repaired.

About the same time that Bill sent his note, a thread on jag-lovers.org brought up the welding issue, and hammered the point home about “repairing” frames. It just doesn’t seem wise, and even if you would have the repairs done following all of the steel manufacturer’s guidelines, you’d probably end up spending about what a new frame would cost. And, having “repaired” it properly, you’d still have a 40-year-old frame at the end.

I think that my left frame will need to be replaced, not repaired. I’m going to have to look around.

Tie-Coat primer in the “boot”

“Tie-Coat Primer” is designed to bond well even to cured POR-15 coatings, and so I’m using Tie-Coat as a base for the topcoat in internal sections of the body and as a base for high-build primer on external sections. I’m trying something out. I read on jag-lovers.org that someone brush paints high-build primer, since the stuff is supposed to be sanded smooth in any case, so why mess with the mess of shooting the paint out a sprayer? When I first read that, I dismissed it, but after a while it did make some sense to me. And so I’m testing it, not with a high-build primer, but with the Tie-Coat, which is billed as a “sandable primer.” I painted the inside of the trunk (aka: “boot”) with Tie-Coat, and I put two coats on the trunk floor, since I’ll need to smooth it very well, especially in the area around the spare tire. I do not plan to spray this area, or any other inside section of the car, with high-build primer. That’s for the outside.

In addition to the inside of the trunk, I brush painted the upper nose section of the bonnet, which still needs attention. I figured that the paint-primer-with-a-brush hypothesis could be better tested on the nose, too. It certainly could stand some smoothing. I’ll be treating the nose as though it has high-build on it, so I’ll be using a guide coat of some sort of paint to mark where I’ve block-sanded. If brush painting works, I’ll put all of the Tie-Coat on with a brush. I still think that the final primer needs to be applied with a spray gun.

Pictures below show the “boot” before and after the primer went on.

February 2003 – Right floor installed, left sill stiffeners, POR-15 trunk

Through January I did some extra work for some extra cash (for extra parts for the Jag). As a result, I spent very little time in the garage. It has been very cold in North Carolina this winter, and January wasn’t the best time to do much of anything without a good heater. The garage space heater just can’t keep up when it gets cold.

I did work on a database of pictures and notes for this site, and I hope to let that have its debut in the next couple of weeks. I have a lot of pictures — taking up in excess of 500 megabytes. So, I have to be ingenious about making them available on the web. My intent with the database is to show the process of this restoration in a clear and searchable manner. If I can do that, other restorerers might find it useful, too.

UPDATE 16 February: This has been a winter to remember. We’re probably going to get another ice storm along the lines of the one that hit 5 December and stopped everything. People who wear aluminum foil hats (to ward off mind control devices) might make a connection between my working on the car and ice storms. I just hope that the last ice storm took out the trees that would fall on power lines, so we might be spared the darkness! Ice is already covering the ground, though only about a quarter inch so far.

Right floor installed (13 February 2003)

It’s been five months since we picked up the car, and I am wondering if we are where I wanted to be with this project. I think we are close to the mark, though I do wish we were done with metalwork on the “tub” — the car body. We haven’t touched the bonnet, we’ve done very little with the doors and the trunk lid, and the engine and other mechanicals are practically untouched.

Getting a floor panel installed was a milestone, however. It seems a turning point from the putzy little fixes to something, well, substantial, even though the the floor panel itself couldn’t go on before the putzy little fixes were done.

Strictly speaking, the floor installation wasn’t entirely “by the book.” Rather than a simple spot-weld affair, as was the case with the original, we decided to use bolts in certain places. No bolts are on the outside edge, since that edge has to accept the outer sill. But we placed bolts (5/16″ width) at points along the edges the crossmember and along the edge nearest the transmission. Three bolts are lined up along the front tab of the floor. Along the back we installed quarter-inch bolts — a little smaller so that they fit along the back lip on the floor panel. These bolts are grade 5, not stainless; but I figured that they will be covered with rust-preventative POR-15 at any rate.

Installing the bolts makes spot welding easier, since the floor panel is held tight to the metal you’re welding to. Since the bolts are for all practical purposes invisible, I thought that this would be a good way of ensuring a tight floor fit without changing the car too much.

Aaron did most of the welding. After a bit of grinding to smooth out some lumpy welds, the entire surface was primed.

On Saturday, 15 February, we removed what remained of the left floor. In order to make sure that the floor area was structurally secure during the installation, we left square tubular beam intact on the left floor area. This beam runs from front to back along the underside of the floor. Once the right floor was in place, the support (if any) given to the body was no longer needed, so we cut it free and removed the vestiges of the left floor. This freed up the otherwise inaccessible space behind the interior rear bulkhead and the part of the bulkhead that faces the independent rear suspension (IRS) — a void of about 3-4 centimeters wide running laterally across the car. I vacuumed the dust and dirt that had accumulated, brushed off what I could, and Rustoleum primed the entire inside of the void. I really wonder why the car was designed to have this inaccessible area, since once the floor panels are on, you can’t rustproof or paint anything in the void.

The picture was actually taken on 16 February, after I had primed the left sill interior. (You’ll see the unprimed left sill below.)

We also did some repair of some hacked up section of the bell housing/transmission cover. This was a repair stupidity like the one we removed and repaired earlier, though the affected area was much smaller. Like that other section on the opposite side of the car, this area had been cut with a pneumatic cutter, splotch welded and then smeared with Bondo over fiberglass screen. It was nice to get real solid metal in the area. We also added some metal tabs along the perimeter where the floor panel rests. Actually the tabs we added are too large, but we will cut them to size when we’re ready to attach the floor with spot welds and bolts.

It’s coming along.

Left sill stiffeners

I had finished the rebuilding of the inner sill in late December, as I recall, but the sill stiffeners weren’t done yet. I kept the remains of the stiffeners and these made good patterns — at least for the sections that hadn’t corroded. As I have with other parts I’ve fabricated, I made a cardboard template and used it to fashion the piece. The stiffeners were made from 20-gauge steel, and I fashioned the middle stiffener from the design I used for the middle stiffener done for the right sill. The secret is to be generous in your measurements for the tabs that you use to weld to the sill. It is easy to cut metal away, but not so easy to add it.

This definitely looks much improved over the way we found the sill back at the end of November. There is still a fair amount of rebuilding to do. The attachment piece for the front frame at the front portion of the inner sill needs to be completely rebuilt — and solidly because of its role in supporting the front end. I’ve decided not to use fabricated sheet metal at all for this (as was the case for the original). We’ll put together something with fortified angle iron which is thicker and stiffer than the original part. (Besides, I have the material on hand!)

POR-15 applied to trunk (14 February 2003)

This trunk seems to have taken longer than I expected — at least it seems to occupy a fair number of these web pages. I’m hoping this picture will do it for a while for the trunk. I applied the silver POR-15 over the primer, and it looks really good. That POR-15 is really solid stuff, and I am impressed with it. I have to admit that I am not impressed with the recommended way of applying it, since the surface preparation never seemed to me to go just right. I would run into small sections (smaller than the width of a pencil) that would seem to resist POR-15. I decided it would be easier, and probably just as good, to prime the clean surface with Rustoleum primer and then apply the POR-15. This seems to work very nicely. The POR-15 bonds to the primer very well, and surface preparation is much more straightforward, not a chemistry experiment.

Saturday, 15 February, is supposed to be warm, though rainy. Temperatures in the “Cat Cage” were around 60 degrees most of the day, and so doing the painting was quite comfortable. POR-15 actually sets more quickly when the air is more humid, since the substance actually uses moisture as a hardener. Normally, I don’t like to paint in temperatures below, say, 65 degrees, but this worked out well.

The paint cured overnight to a hardness that feels very much like a “powder coating.” I am tempted to spray it and perhaps use something other than the “silver” brand. I’ve heard that the sprayed clear POR-15 dries very smoothly and is used as a primer coat for that reason. I am planning on coating the inner sills and stiffeners very well — probably a triple-coat of silver, just to ensure that the inner sills are well sealed from any moisture that might get into the area.

November 2002 – Various small parts

Right Engine-Tranny Cover

A previous owner of the car must have been a happy owner of a pneumatic cutting tool, because he made some interesting cuts to gain access to the transmission or the transmission bell housing. It’s not particularly clear what exactly required such invasive and destructive work to be done. I was thinking that perhaps there was simple laziness at the root of it. For typical adjustments, the E-type has adequate portholes going into the transmission area. But perhaps this was starter work? A clutch job (unlikely, I think)? We shall probably never know.

Anyway, I fashioned a replacement piece for the front engine/transmission housing wall out of 18-gauge steel, and I cut out the damaged piece from the transmission cowel. That piece we replaced with another piece of 18-gauge steel. Aaron did the welding and the grinding.

It is amazing what was considered acceptable repair for previous owners of the car. The pieces we took out were welded, of course, but the welds consisted of blobs of metal with vast voids between them. There were no additional pieces of metal welded into a lap over the holes that were cut (roughly, as is always the case with pneumatic impact cutters). Even the roughly cut slices apparently weren’t even hammered the slightest bit to make them straight. It was, apparently, simply jack-hammer cut and splotch-welded.

I find I have little patience for this shoddy workmanship.

This was not a difficult repair to do. It was really a matter of cutting metal and welding it into place. Aaron did a very good job at putting it all straight, and now the piece is markedly more sound and complete. A good success for a first welding job on the Jag.

Some Painting — Black Stuff

In short, one of the IRS supports, the engine mounts, the IRS access plate, the water pump pulley, the passenger-side (right) air vent, and (primed only) the mounting bracket for the voltage regulator. The voltage regulator bracket is supposed to be silver color.

Radius Arm Cup

The couplings between the floor panels and the two radius arms extending from the rear suspension need to be installed before the floor panels are installed. We looked at the existing cups and one of them was corroded beyond repair. I ordered a replacement for it. The other one still lingers in my mind as a repairable piece or as a replacement piece. We did go ahead and repair the cup that still has structural integrity, though questions remain because of the threading in the center of the coupling. They are not exactly well defined. I could, perhaps, go ahead and retap the threads with some success. At this point, we are going to wait until the new part arrives (sometimes after the Thanksgiving Holiday, I was told) and then we’ll make a decision about the replacement. I definitely do not want to install a restored part that will fail after a few thousand miles!

The replacement “radius arm mounting cup” costs US$55.00 plus shipping. I took the restored piece into the hardware store to see what I could find for mounting the piece onto the floor panel and to see what the threads inside could actually do. It appears that the rust damage didn’t corrode into the piece, but rather filled into the threads. I think as metal rusts, it expands, so this might be only partially reassuring. I could, of course, tap the piece into a larger thread size, but then I would need to use a larger attachment bolt — a risky proposition, since the bolt also goes through a bushing assembly. I could also add metal to the threaded area, and then drill and tap it, but I’m not clear that the strength would be as good as it should be.

Rear Floor Stiffener

This is a part I had to fabricate, since it was not available from my US supplier, and there were no plans to import any more (from what I could tell from the supplier, anyway).

It is a simple part to fabricate, though I’ve found that any fabrication is putzy. I created a template from the original part, transferred the pattern to 18-gauge sheet metal, cut it out, bent it, welded it, and drilled it. This part probably took four hours to create, all told. I did do a bit of extra work on this piece, just to make sure that it served the purpose of “stiffening” well. I reinforced the attachment tabs with a double thickness of metal (two times the 18-gauge metal, that is). It’s currently ready for priming and installation, once the floor panels are in place.

The number written on the piece, by the way, is for the part tracking system I developed.

Repair of Trunk Floor

We fixed the bondoed hole that was located next to the hole where the fuel filter cup extends below the body. This was damage that didn’t become apparent until we had removed the paint from the inside of the trunk. The fix entailed cutting out the corrosion and the entire fuel filter cup hole, even though the rust damage was isolated to one side of the hole. I figured it would be easier to create an entire hole than it would be to try to fashion a piece and attach it flawlessly to the “good” metal of the original hole. Once again, this was a matter of exactly fashioning a replacement piece, welding tabs to the hole, and welding the new piece onto the tabs.

The picture is, perhaps, not so very informative, but it does have a certain artistic quality, I thought. It is almost an impressionistic rendering of the repair. Monet in the Cat Cage garage! This is the metal after most of the grinding was completed and before I put a layer of Bondo on. At least my Bondo application is over real solid metal, not fiberglass mesh.

November 2002 – Right sill stiffeners, rear bulkhead, some priming

Right Sill Stiffeners

After the manufacture and installation of the sill end pieces on the right sill, I installed the front and rear sill stiffeners. These are littlemore than brackets that fit below the door frames — below the “B”-pillar in the rear and below the structure that holds the door hinges. They turn the (roughly) square sill into two triangles, and that’s why they are so good at stiffening the sills. I was thinking about putting a third sill stiffener in between the front and rear stiffeners, but after I got them in, it seemed as though there really wasn’t that much room between the stiffeners. At least not much to worry about. (I have seen a third stiffener installed by some restorers. They use a modified front stiffener.)

I had to fabricate the rear stiffener myself, and I used the existing rear stiffener on the left side of the car as a guide. That stiffener is intact, and it needs a little repair. I just created a template out of cardboard (the side of a Budweiser 24-pack), and tested it out by folding it and placing it into the sill. Once I was happy with the fit, I just cut the metal, leaving a little bit extra material so that I could trim it down after bending it. I installed both stiffeners with spot welds.

They really do firm up the sill.

Rear Bulkhead, Some Priming

The right rear bulkhead, you might recall, was pretty badly corroded about two inches up from the floor panel and nearest the sill side. I cut out all of the corrosion, cleaned up the internal structure that supports the rear bulkhead, welded in some tabs, and spot welded new metal cut the same shape as the area I had removed. After grinding it all flat as best I could, I put a thin layer of Bondo to smooth out the surface. After sanding, I primed the rebuilt rear bulkhead and the right inner sill. You might notice that I “missed” a small area about halfway along the sill. Actually, I didn’t prime that area, since I’ll need to weld the cross-member to the sill at about that point. I figured I didn’t want to cook my primer! I also primed the right rear wheel well, which I scraped and scraped and scraped to get off the various coatings of rustproofing and greasy girt.

Need Radius Arm Mounting Cups

I’m just about ready to install the right floor panel. I have a bit of sheet metal repair to do near the engine/transmission wall, but that is fairly trivial. After I installed the floors I was hoping to be able to install the “radius arm mount cups” — little fittings that hold the arms that come front from the independent rear suspension. But, the mounting cups need to be put into place before the floor goes on. Some of the holes intended for hardware are not accessible after the floor is fitted, since they are then entombed in the rear bulkhead. So I have to get at least one new mounting cup, possibly two. The mounting cup that we removed from the right side was damaged by the cutting tool, and it was at any rate pretty badly damaged by rust.

The mounting cup on the left floor is in better shape, and I will know more about its usefulness after I get it off. I’ll probably grind the hardware off on Monday night and take a closer look. If it is serviceable, we’ll probably use it on the right side after we clean it up and rust-protect it. I want to get on with the floor panel installation, so that we can prime, rock-guard, and paint the underside of the car. Then we can get it back right-side up, and move on to some mechanical work!
