Off Topic Metal working Question

[dgsaz]

I put this in "off topic" because it deals with parts from a 66 Honda m/c not a VW. If the m/c was on a trailer behind a 66 bus would I be on topic?

The photos show a fender bracket harvested from an old rust steel OG fender.

I thought the three layers of metal would separate after I drilled out the "rivets", not so. I think these were puddle welds through the holes and ground flush.

There are three layers of metal with no visible, obvious welds.
Hammer and chisel didn't work.

So, do I take this to a welding shop and have it heated until the invisible weld holding the thing together let loose? Is that what's holding it together?

Thanks all. Enjoy the day.

What is the intent with this piece, are you going to copy it with new metal, or just want to dissect it?

It looks like you still have some small sections of the welds holding on even though you drilled them out. It doesn't take much to hold two pieces together, think of a spot weld. Notice the discoloration on the edge of some of the holes.
My guess is you want to save the outside pieces and replace the center one.
I would take a Dremel with a small carbide bit and by reaching inside each hole, grind away just the center plate until you see a parting line all the way around the hole. If you don't see a line, it's still melted together right there.
I would start with one of the end ones.
Or, just make the holes bigger (probably not what you want).

Good luck,
Dan
