After great lack of motivation ... I finally drilled and countersunk all the holes in the AN970 washers to make the hubs. I then developed a streak of rash bravery ... and welded up the hubs. It was pure dumb luck that the first one came out with the holes alternating each other (end-to-end). The 2nd one, both end washer holes were lined up ... darn! It's wonderful to remember these things after they are welded.
So I put the cutting disk on the hand grinder and cut one of the end washers back off ... adjusted it so the holes were alternating opposite of each other ... and welded it back on. I'll probably get it right the first time ... on the next set of hubs that I make ... for the 26" wheels.
