    Back to our door panel stainless, the correct studs came in for the CD stud welder, and tests have shown them to provide the solution we need..







    These studs have much less mass at the end, for a lesser capacitive charge needed.










    Tested on a piece of 19 gauge steel, note the back side has no discoloration whatsoever. Allen used a pair of Vise grips to give it a twist test to see if the weld would release. Where the one that is cut got too close to the cutters, the others did not release, and in fact distorted the shape of the metal because they held so well. The one pin shows a good 90* bend, which is what will be used to hold the stainless onto the door panel per the same design as original.













    And now for the next wrench thrown in our bumper modifications.. Welding causes shrinking, so TIG welding the slotted brackets onto the back side of the bumper invariably causes flat spots on the front side of where the brackets reside.. So some quick work on the South Bend to make a purpose built punch so we can do some metal bumping on the bumper..



















    ….or the motion picture visual....

    And after a bit of metal bumping, we have the area down to less than a 1/32 depression, which should be just fine for the copper stage of plating..







    Note the minimal gap behind the straightedge. One down, three to go...

    In another back up and punt moment, we found some interference with the new bumper brackets and the rear tailpan. In order to tuck things in nice and close, we need to trim a portion of the rear channel in the tail pan. Nothing a pair of tin snips and a file can't resolve. Pay no attention to that green paint. The bare edges will be touched up with SPI epoxy primer..















    Our final test fit on the back bumper before chroming:

    On to our tail light hidden fuel fill...…

    This thing had been giving us fits in intermittent operation, and it hasn't even been exposed to water yet. Looking at the wiring (why can't we keep the colors consistent through?)…..







    Well this isn't part of the problem... found a couple loose terminals..










    So we decided to eliminate the original trailer connector and term board connections and replace with Weather Pack connectors. The relays will be mounted behind the rear seat for a closer proximity to the tail light, and the DPDT toggle switch will be replaced with a DPDT momentary rocker.











    On a side note, a recent task for the day job involved some cherry trim boards that were pre-stained and we had difficulty finding a match using Minwax blend-fill pencils. The Number 3, 5, and 6 were all off....







    However, kneading the 3 and 5 together showed promise. But how to do that on a larger, less time consuming scale. I will say none of the wife's wax melting pots were harmed in this experiment, but the trim screw holes in stained trim were all but invisible when done. The pencils were unwrapped, cut up into 1" lengths, then melted and mixed together. In case someone else needs to do the same...

    Thanks!!



    So part of our fitment exercises with the bumpers has been to get them in a little closer to the body for more consistent gaps to the body. The rear bumper had it's challenges with needing to notch out the lower lip of the tailpan.











    The front would be no different. The front nose of the frame rails was hitting the rear side of the factory brackets and preventing us from locating the bumper for a good consistent gap..




    So some modification was in order so that the frame horn could fit in closer to the rear side of the bumper..




    We now have a much better fit..

    Thanks RD!


    So we've started on our wiring, what can go wrong? First item on the list is the interior lights, we had run the wires before the headliner went in. We had installed a second light just behind the rear seat and the plans were to gang it to the front light by putting two wires into a 12 gauge pin in the weatherpack connector. This should be a 5 minute job.


    Only the weatherpack connector would not fit inside the void in the ceiling. Since we don't intend on using butt splices, we had tried installing two wires previously into the w-crimp lamp base contacts as shown:









    This sample we did using the red Teflon insulation fit inside the brass "tubes" of the lamp base perfectly. But the insulation on AAW wiring is much thicker. Ahhh, the dominoes they do fall. So let's see what we can do to modify the brass tubes to better accept the wiring going in. Our local Ace hardware has a good selection of "model" tubing in aluminum and brass, so with fingers crossed, we picked up the 3/16 size.






    The ID measured out to .154, about .010 larger than what the lamp base came with. The outside diameter of the tube was turned down on the lathe to a size that would play nice inside the plastic housing and not bind on the spring.





    Some aluminum bar stock was drilled with a tight clearance hole for our new tube, and served as a fixture to swage one end for spring retention. Sorry, missed pictures of some of the details (fire the photographer). The opposite end was swaged after insertion into the housing..





    With the tubes now sized for two wires, we got the front light installed. The rear light and its single wires should now be a breeze.

    Progress from yesterday, while Jared was blocking out some of the window garnish moldings, I worked on the door panel stainless trim to ready them for stud welding. Mike had used the trim repair tool to remove the dings, which were then filed smooth.



    The last 65 years had left their mark; we had numerous scratches needing removal as well. We started with 320 grit on the fine pattern palm sander, and progressed our way up to 8000 grit trizact..











    This is the final using the 8000 grit, and we'll start the buffing process once the stud welding had been completed..

    With the stainless prepped, we turned attention to the window garnishes. They were sprayed with three coats of SPI epoxy.





    Today we went to A&A Metalworks in Ridge MD to get the studs welded in place. This sample shows the studs, where three have been folded over to a 90. This is how the factory held them onto the door panels as well. Note the back side shows no heat pattern with the Capacitive Discharge welder.





    Welding the studs onto the stainless trim...

    A test to check the heat the welder introduces into the panel..

    This shows these welders make a good choice to use where cases of heat sensitivity may be an issue.

    Thanks Sid!


    Happy Easter everyone!

    Our wagon progress from this weekend, we finished up the interior lights. Here wiring up the rear light. The included pigtails were discarded to eliminate a butt splice, and our newly installed wiring made use of new lamp base contacts (W crimp) from Repair Connector.












    The lens used in light fixtures like these are typically plagued over the years by overheating and then cracking, so we opted for a 1004 LED replacement. Should keep things cooler for longer lens life, and brighter!!












    Onto more electrical issues, the "hidden fuel door" we had purchased was so intermittent in operation that when we had dropped it off at Absolute Rod & Custom Paint to test fit to the car when they were fine tuning the bodywork, we were second guessing whether we should use it at all.

    All the harnesses came into a terminal board with wires going to the relays on the opposite side. Some of the terminals had as many as three wires in them, and Mike Flores found about 6 loose wires. Splices didn’t carry the same wire color through, making trouble shooting a bit of a challenge. The toggle switch (which should have been momentary contact but was not) had some home-made fork terminals. This thing was looking more sketchy with everything we looked at next. For a store-bought product intended for an automotive environment, they should find someone more competent in wiring.











    To get rid of the terminal board, we opted for weather pack connectors, one to each of the end terminations (switch, fuel door, power source). We eliminated the triple wires to single terminal by jumpering, making use of two wires in a single pin, and jumpered as required.
















    Our new wires going into the relay connectors made use of new Packard 56 style female spade terminals from www.repairconnector.com (more W-crimp) These were also jumpered two wires to a pin where needed.












    The toggle switch was replaced by an automotive grade MOMENTARY rocker switch from McMaster. Works flawlessly.

    Not pretty, but much improved. The relays will be located behind the rear seat on the sub box, conveniently between all our end points. Just like our speaker grilles, black plastic really doesn't belong in plain view in a 55 Chevy. So our more highly functional rocker switch will be hidden inside the glove box..

    So now that I'm back from the short hiatus in Albuquerque, hanging TV's for the day job... We did get to see some sights, here's cars and coffee attendees on April 17th..



















































    Later that same day we rolled past the car wash from Breaking Bad fame...
