Skin back on drivers side rear quarter

The day started by cutting out a 12" section of the wheel well at the bottom rear. I was going to wait to do this until later, but since I had a big hole in the side of the car, I decided it would be easier to reach now. That took a couple hours to get fit up, then about a half hour to weld up. As I was welding, I noticed about 3 places where the former body guy overlapped panels, so I spent about an hour cutting out lapped pieces and cleaning up the rusty areas under them.

Now that the wheel well is in good shape it was time to weld in the first of the skin patches. I started at the back by fitting up and tacking in the biggest piece. Since the piece was long and thin, I welded in 4-5 tacks, then hit them with compressed air to cool them off. I also was very careful to move around the panel as evenly as possible.

With the big piece welded in, I moved on to the arch. It was cut in two so I welded it together on the bench and ground everything down. I rolled it a couple times on the e-wheel to give it some shape and then went to fit it up... Wouldn't you know, it was about 1/8" too wide at the gap. Seeing that it was sticking at the lip, I cut the panel back in half and allowed the cut to be a bit pie shaped. That split the difference and I was happy with the fit.

Just a note... It's really hard to hammer and dolley on the arch piece. There is a close off piece at the fire wall that you can't get your hands behind. There is a gap just big enough to get a pry bar into, so I used one of those to push out on the low spots while I hammered on the skin on the high spots.

After I ground down the welds, I decided to start cutting out the trashed out engine bay. I have a lot of clean up to do, but the major sections have been cut out. I'm going to try to get some paint on the bare front end tomorrow, but if it's too wet or too cold, I will start the clean up on the engine bay supports.
This is a view from the rear tail light on the driver's side. You can see the patch to the wheel well just inside the hole in the quarter panel.

Everything ground down. MUCH nicer than the recessed and putty filled patches that were there.

More work on the ghia's driver's side rear arch

Back to flying solo again today. It's killing me that I have a big hole in my rear quarter, so I decided to address that area today. First mission was to cut apart the vertical weld that was lapped about 2" over and get the metal straight, then reweld it. I borrowed a body saw from my wife's grandpa and that did a great job with the accuracy of the cut. It also kept the cut thin enough that the welding went off without needing to fill a bunch of blow out.

After the vertical weld was straight, I saw the piece we welded in yesterday needed a bit of reshaping to make everything tight where the skin will weld up. I spent about 2 hours going back and forth beating and fitting the arch until everything looked tight. As I was doing that, I noticed the forward piece that we though was good, actually needed help. I cut out another 10-12 inches and fit up a repair panel. As I was welding that in, I noticed a 1/4" crack above the patch. After hitting the crack with a steel brush, it opened into a dime sized hole, and had about 6 smaller friends show up for the party!!! I then cut out the hole and his friends and welded in a patch.

In the process of making the arch pieces, I realized that I could hammer the lips out against a form, but then I had to shrink the lips to get shape into the arch. I decided to split a bolt and use it as a shrinking fork. It worked like a charm. I could make tucks, then hammer them out against a wood block, then finish with a steel dolley.

I made a fairly large patch for the rear section of the quarter panel. I used the same wood form to fold the lip. I had to shrink it just a bit, then hit the panel lightly with the english wheel to give it some shape.

My wife's grandmother was in town (other side of the family), so we went out to eat. After that I caught game 1 of the world series, then snuck into the garage to apply a quick coat of POR-15 to the inner well so I could get the skin welded on in the morning.

Vacation lends time to work on Karmann Ghia again

I'm on vacation this week (it was a use it or lose it situation) so I am finally back on the ghia project! I asked my wife's grandpa Cecil if he wanted to help work on the car and he generously accepted. Cecil was a machinist for TWA for about 30 years and he's tackled an insane number of projects that require custom fab of sheetmetal, chassis mods, engines etc., etc., so I was happy to have him on board for just about anything. My dad also wanted to get involved, but he hasn't done much bodywork in the past... I haven't had much help over the years, so I had to think of how all of us could work and not be tripping over each other and we also needed to have enough tools to go around.

Before everyone arrived, I moved the car into position, cleaned up the floor and started grinding bondo out of the d.s. rear quarter. When all the crap work that had been done to the quarter was exposed, I cleaned up and got the tools all ready.

After we got done with small talk, the faces got serious and my dad quickly volunteered to organize or clean up my garage since he could see the car was going to be crowded. How perfect! I needed some shelves installed and I knew he'd bang them out perfectly. I decided to take the front end since it was custom work and the idea was just in my head. I showed Cecil the driver's side rear arch and asked if he'd be happy working on that.

With the work assigned, we all started tearing into the jobs at hand. We marked out the arch and Cecil started cutting away the sheetmetal. I cleaned up the heater vent opening and made my patch for filling it in. Dad was well on his way with the shelves.

When Cecil got the arch cut out we did some detective work and found a Tabco panel was at the back of the repair, the original car was the next layer and a donor car was the third layer. The last body guy overlapped all the panels about 2", beat them into submission, welded them together, then put about a 1/4" of bondo on top to finish everything off nice and smooth. We also found that he beat the tar out of the inner wheel well since things didn't line up for him.

Cecil set about making a new outer lip for the inner wheel well. He cut a piece of 3/4" press board to the curve of the opening, then bent the lip over the edge of the press board. He checked it for fit inside the arch sheetmetal and everything looked good. After some fitting we tacked it up and found there was a twist in it and spent about 30 minutes getting it straightend back out. I finish welded it after Cecil went home for the night.

More Paint removal

I tried a different paint stripper today and was quite pleased with the results. I used KleenStrip's aircraft remover. I found an aerosol at walmart, but I couldn't find it in the liquid form. I taped off the trunk that has already been sealed and went to work on the weatherstrip channel. It took 2 passes to get most of the paint off, then I switched over to a wire wheel in a drill to clean up the last bit of paint. I was much happier with the aircraft stripper than the bix I used before.

The aircraft stripper works really fast. It says 15 minutes on the can, but it was more like 5. I could actually feel the chemicals burning me through my blue rubber gloves. After everything was stripped I wiped everything down with mineral spirits.

I will be stripping the wheel wells next. I suspect I will work in small areas so I can stay on top of the work.

Plumbing the Air Compressor

The project went on a slight hold this weekend while I plumbed in my compressor. For the last 15 years I have just had a 50' hose connected to a water separator/regulator connected to a ball valve. Since I am going to start painting bigger pieces and parts I wanted to be sure if the air kicks on, I have a dry supply.

My firm has a 6 bay garage behind our main building. It used to house a car mechanic. I went out and poked around and found some old 1/2" galvanized piping that was used for supplying air to all the repair bays. I like to be as green as I can be at work and in life... I am also always on the lookout to save money if at all possible, so I asked if I could salvage the old pipe. My boss said I could have it if I was willing to do the work to remove it. In all I removed about 40' of piping and a handful of elbows, a "T" connector and a union.

I saw this diagram referenced on a few other websites http://www.tptools.com/StaticText/airline-piping-diagram.pdf and followed the concepts. I installed a 6" riser at the tool end and sloped the main pipe back toward the compressor. At the compressor, I upgraded the connection at the ball valve from a 1/4" nipple and adapter bushings to a larger 3/8" nipple. Then I ran a 3/8" lead-in hose line (from Harbor Freight) to a 1/2"-3/8" adapter bushing. I installed a union where the hose connects to the hard line so I can break everything apart from that point without having to mess with twisting up the hose. At the other end of the line I installed a 6" riser on a "T" connector out to the dryer/regulator. On the bottom of the "T" I installed a 6" nipple and a drain cock at the bottom. All of this added together should force the water in the line back toward the compressor, or at the least, it should drain into the 6" drain at the bottom of the "T" connector.

My father came over and helped me assemble the piping in the driveway, then we put a few mineracs on the wall and clipped the piping in place. After the piping was up, I connected the union and the lead-in hose from the tank.

I wound up purchasing just a few items: the drain cock, yellow (gas) tape, a bushing, 2 elbows and 4 nipples 5" long. I needed 1 piece of pipe cut and threaded. The man in the plumbing dept at Lowes was nice enough to do it for free since I had a handful of other plumbing supplies.

I tested the system out tonight with about 90 minutes of constant grinding. I saw some water about an hour and 20 minutes into the operation. The compressor ran almost the whole time. Once I drained out the dryer and drain cock the air was totally dry again. With my old setup the water would show up in about 20-30 minutes. I suspect if I drain the cocks every hour or so I should be dry all the time. I could also probably use a new dryer as mine is 15 years old and just a cheapo craftsman. A Sata or other paint-specific dryer would probably be much better.

Filling Left Air Vent

I was able to work for just a short while on this long holiday weekend. I managed to weld in the DS air vent patches I made a month ago. I've been finding it very difficult to weld on the bulbously curved nose. Everytime I weld up a nicely fitted patch, the metal shrinks up and winds up flat. I have to spend 1/2 an hour hammering the patch back into shape. I was told awhile back to make my patches just a touch small so the metal wouldn't pucker if it was heated too much. The smaller patch (right side of the photos) fit extremely tight and had much less shrinking than the bigger (left side of the photo) section.

I was able to hammer most of the patch, but the area right next to the inner fender proved very difficult to fit a hammer into. I also tried using a screwdriver and very small pry bar. The inner fender was too flimsy to get any pressure. I am going to try to bend the chipping end of an old brick hammer so I can get into the acute angle and bang out the patch... If I can't hammer it, the filler will be about 1/8" to 1/4" thick... I'd like to avoid that and get closer to 1/16" of a gap between patch and my template.

Left Side Lower Front Inner Fender

I did a final fit and got my inner fender piece welded in tonight. This was probably the most difficult panel I have fabbed up to date. There were quite a few wrinkles and the flanged curve at the bottom gave me fits. As you can see the fit was about 95%, but again, the panel was difficult to reach. I would have liked to do this with the body off, but I don't plan to seperate the body for another month or two, so it was this way or come back to it.

I am still under the impression I am two weeks behind schedule. I have the other inner fender, some cleanup of the duct work, the fresh air grills and headlight buckets left to do. With the long weekend ahead, I am planning to get the left air grill complete along with the left headlight bucket. Then I'll hit the right side for the trifecta (inner fender, air vent and bucket) next week.
