In other words everything I'm seeing on this site is a 3/8" hole-saw style cutter. I realize we are only talking about a 1/16" difference...but metal is metal.
So lets here your thoughts...…. | | | | | Joined: Feb 2004 Posts: 29,850 Kettle Custodian (pot stirrer) | | Kettle Custodian (pot stirrer) Joined: Feb 2004 Posts: 29,850 | Back when I was teaching auto body work, we used a kit that consisted of a spring-loaded centering plunger and several hole saw type cutters that threaded onto the shank. They varied in diameter from 1/4" to 1/2" in about 4 steps. The nice thing about that setup was that the cutter could be matched to the diameter of the spot welds, and it didn't make a hole through the lower piece of metal. Once the outer panel was freed up, the residue could be ground away, leaving flat metal with no holes to fill. We could also drill a series of holes in the replacement panel, clamp it into place, and fill the holes with MIG wire.

I will be tossing these used bits to the back of the drawer. Never even considered that spot welding in the day at the various assembly plants might have used a slightly different diameter machine???
What I see and I'm certainly guessing is something along the lines of 5/16" in the '59.

I addition, how long you kept the spot welder going would lead to a slightly larger or smaller spot. Of course, now days robots are doing all of that, so I imagine there is much less variability.

I am currently digging back in to a 1953 3800 (one ton) with a nine foot bed. I've owned it since 1979, and drove it until 1982 (or so). My wife got me involved in restoring it back in 2002, got the body removed and the frame redone, then things came up. Now I am retired and starting again. If anyone is interested I have photos on Imagur ( https://timwhiteblues.imgur.com/ ). I live way back in the woods in the Ozarks on 40 acres at the end of a 2 1/2 mile private road. Tim
