Hi folks. I have a shaft I am trying to repair. The shaft is the upper shaft for a Delta 20" wood cutting bandsaw. Some time during this machines life, one of the upper bearings siezed up and the shaft spun in the inner race and ground away at the shaft. A previous owner "fixed" the saw by replacing the bearing, but did nothing to the shaft. the bearing area in question is approximately 3/4" in diameter and the shaft is steel.
On a piece of scrap, I tried building up a section with multiple weld beads axially along the shaft, I chucked this up in a lathe, and the cut was horrible. I have decided that this won't work.
I was wondering if building it up with silicon bronze would be a better method. I have put a few beads on my scrap piece but have yet to true it up with the lathe.
any suggestions for this repair would be appretiated.
The welder is a Thermal Arc 185TSW, and I am an "enthusiastic amateur" weldor. Thanks, Andy
