This axel pin thing has become more complicated than necessary. I had my frame with the metal guy I use for complicated fabrication, and for two weeks he did nothing. I got impatient, and started looking elsewhere but all the small job shops have closed down or moved out of state. Today we mostly have aerospace high volume shops around here, and had a hard time finding a shop willing and or capable.
So I bring my frame to this guy who agreed to replace the bushings, oversize the axel pin, open the axel bore, and make 2 new pins. 4 days later I pick up the frame and his employee decided to go down different path. He reams out the hole to .760, and makes 2 new pins.
I took it home because it was fitted nicely assembled. But when I inspected it up close I didm't like the finished result. The pin/front bushing was OK, pin/axel really nice, pin/rear bushing sloppy. Plus the roll pin hole was not clean either.
So, I'm taking it back on Monday and he is going to bore out the old bushings, fabricate new ones, and new pins, making the rear bushing the same size as the front.
I sandblasted the area clean, and you can see that there is no braze holding these to the frame so I'm pretty sure J-Mech is right about them being friction welded. See image.
I hope to have the frame back by next weekend, and I will post images when properly fixed.
