Due to work commitments yesterday (on my day off no less!), and rain on my first vacation day I didn't get as much done as I wanted. Wednesday afternoon I was able to get the top of the cowl off. I was tickled to death in the fact the current spot weld cutter I'm using held up excellent. It's a Blair cutter with double sided replaceable bits. What tickled me was I only used one bit (both sides though), to do the entire cowl. I previously had an Eastwood cutter when I did the cowl on my fastback. I went through six bits (single sided), to get the top off of it!
Once opened up it was better than I feared, but not near as good as I had hoped for! I knew the dams (rings), around the vent openings were rotted loose on both sides. They had been in there just rattling around. I previously had reached through the openings from inside the car and pulled both out! Knowing this I had already bought the left and right cowl patches.
My disappointment though was in the amount of rust across the entire forward edge of the cowl. It wasn't the length of rusted area (towards the rear of the car), but the width...the entire thing from side to side. As such it allowed water to drain onto the top edge of the firewall too, causing it to rust through. Not a wide patch, just the entire way across. The center area of the lower cowl also had deep pitting and small holes. Replacing the firewall was not an option. I knew I'd fab the entire top and down an inch into the face of it. The quandary came with the lower cowl. Replace it with an entire assembly or fab the center section of it!
The upper cowl is in good shape. The cheapest I could find a lower cowl for a 65/66 is $180 + shipping. Add to that, what to do with the patches I had already bought? I talked over my options with a friend Wednesday afternoon, and then talked to the wife when she got home from work (she controls the purse strings on this project!). I told her I had pretty much talked myself into fabrication work since I have the metal on hand already. I also have the ability, time and labor to do it. Money for a new lower cowl I really DON'T have! I still have more primers, paint and sealers budgeted out already.
Since work stuff yesterday kept me from the car, I was in the house when the wife got home. She told me she had done her travel claim at work for a recent business trip. She also said she was getting money back which I could have to buy a new lower cowl! THAT'S why I've kept her around all these years!! Call me crazy, but I politely declined and said the money could go elsewhere (my daughter is graduating college in 3 weeks, it'll go to helping out with her grad presents instead!).
This is the last MAJOR area of sheet metal repair to do on the car. I still have some smaller projects to take care of, but they all PALE in comparison to this and the recently finished floors! With that said, today I took the plunge! Here's the pics:
This is what the cowl looked like when I opened it up.
Here's the cowl section removed, the new patches pretty much fitted into place and the main portion of the center area fab'd up.
Once I had the main part done I started on the top lip of the firewall. Since I'll need to install it before the lower cowl goes back in, I figured might as well get ALL of the major fab stuff done today! Here's the rusted out area that necessitated the repair. You can see some of it at the radius from the vertical part of the firewall to the horizontal area. It's pretty much like that all the way across, just varying levels of damage.
Here's the new lip formed. I still have to make a template and form the front edge that received the lower cowl.
All together the work took me about six hours today. That was primarily due to the lack of proper equipment. If I had a shear, metal break, bead roller and shrinker/stretcher it would have only taken an hour or two! The firewall lip is 55" across with a 1" vertical section to weld in and a 2" lip area to work with. I had to cut it out of a 4' x 5' panel with cutoff disk in the grinder. The 90deg bend was then hand formed between two steel "L" in my bench vise...5" at a time, back and forth in three steps. Since I ended up with a straight 55" long "L", now I had to get the arch in it. This was done by multiple relief cuts across it. Once I get it fully done I'll weld the cuts back up and grind flush before installing it. I also had to hand form the center section much the same way. Since it was a MUCH shorter piece it didn't take as long to bend. The tapered "Z" section at the front edge was a little of a pain, but it now matches the original contours and you can see in the pic that it lines up nicely with the patch panel. I formed the arch in the whole thing by using one of the support poles in my garage to bend the arch in. Necessity is the mother of invention! I don't have a bead roller to put those back in. Since the ribs are in good shape on the original center section I'll just cut and section those in. Due to the various windshield wiper mounting points and recesses in the rear of the cowl there's no way I could make those. The section is also in excellent shape. I'm just going to section it back on. Hopefully, with an early start, I'll have it done by tomorrow evening.
Yeah it WOULD have been MUCH easier to buy a new lower cowl. My labor is free though and I already had the material. It was a tough call, but I would have had to put other things on hold which NEED money to get. I was hesitant at first, but as usual, once I started I just chugged away at it. I'll post more pics once finished and before the top goes back on. Wish me luck!!
p.s. Almost forgot! The last body piece I need for the car to 100% was a front valance. I had the money set aside and was ready to spring for it this past weekend, but decided to wait...just in case! Lo and behold an NOS valance popped up on Ebay at the beginning of the week. It had no bids, no reserve and a VERY low starting price. SCORE! $55...sole bidder!!! Can't wait to start fitting body panels soon!!
