Wagon Progress

Nice find on used clamps. I'll take old name brand over new crap any day. Just to mention on the new crap, Tractor supply stores randomly have great prices on useable extension pliars. Got several combo packs with a 6" ,8", & 12" extension for $14.99. Way better than HF, just don't let the long ones overtwist. Stopped at 2 stores in Tennessee last year on vac with wife to look for more.
 
I tend to tighten Vise grips where they are a challenge to remove. In using that practice on a buddy’s cheaper versions, they are quick to show their “limitations”. All of mine are USA Vise Grips, and anymore, based on some of them being made overseas now, sales like the one I just attended for used, older versions are the only ones I buy.
 
Progress pics from last night... Yep, we've been block sanding..



Using Evercoat 416 to address the few low spots..







Honing up on my painting skills with brush on seam sealer





Today's lesson is on media blasting and stretch damage that occurs. Here’s what a sand blaster will do to a roof skin when blasting the braces underneath.







Our blaster was doing the brace from underneath/inside and the inadvertent stray media hitting the adjacent roof skin stretched it, pulling it inward toward the media stream . On the outside the “unstretched” area shows as a high spot, the stretched part that needs shrinking is seen as a low. So if you must media blast any braces or internal structure, block off the skin next to it so no media touches it. Save yourself the extra body work.

We fixed the lows by locating the exact spots on the inside that needed shrinking and tapping outward into a small shot bag. To locate, a rare earth magnet is placed outside on the roof skin in each low spot, and some grinding dust finds the magnet on the inside where we can mark the perimeter both inside and out, and work with one person on either side to remove the lows. (See video, magnet marks highs or lows, it doesn’t care) For multiple lows, mark both sides of all spots and number them, so you can move from one spot to the next, calling out the number desired to your shrinking assistant. If your car is too clean to have grinding dust, look under your bench grinder.

Magnet use video:


Note on the inside roof skin picture the multiple numbered circles where we found low spots to address.

So we've been blocking out epoxy primer, it sure is nice to be able to rotate the car where you need it instead of sanding upside down on the bottoms of drip rails.



But then you walk past the Driver's A pillar and see holes that shouldn't be there.





I don't know how I've missed this before. We did have this same repair done to the other side, I guess with the roof damage confined to that same side I must have not thought this side was suspect. Goes to show, check ALL problem areas, especially if issues show on one side.







Inside the hole has a minimal amount of surface rust, especially for 64 years old. Safe to say the damage was caused by water/dirt accumulation between the center structure (the one we're remaking) and the outer skin. Oh well, it's been a while since I've had a back up and punt moment. Glad this was found before the green kandy went on.

Starting to make the new replacement for the inside, using 14 gauge cold rolled steel.



Quite a bit if stretch added for the part to match the original..





Rough shaped on the MH19, tuned up a bit with body hammers, punches used as anvils, and various other implements of destruction. Trimmed and fitted:







All ready for welding. Meanwhile, Mike has been working on the pointy end of the arrow, here stretching an inside corner to better fit the housing....


And adding holes for the plug welds....





 
After seeing your metal work, I'm just embarrassed by mine. I was always on the finishing end, but had one of the best metal men around working with me and eventually for me. I was always amazed by his craftsmanship, and watched a lot of how he did things, but he made it look way easier than it is. He was an absolute magician with what he had to work with, but sadly he passed way too early at 59. I think about him often, especially when I make a patch that comes out especially nice, or put on a door skin with no filler needed (which he always did). Never saw him put on more than 1 coat of filler and 1 coat of 416, and it was always ready for primer. Thanks for the updates, and I really envy your talent.
