ri702bill 11,421 #1 Posted March 5 (edited) After machining the C series Axle for bushings, the worn spots at the outer ends of the spindles needed to be addressed. My son TIG welded the worn areas up using a Silicon Bronze filler rod while I had to figure out the fixturing to allow cutting using the Boring Head in the Milling Machine. Rough alignment was done using a square collet block in the vise & a split sleeve in my 1" endmill holder. Final tweaking using the dial indicator. Cut the weld to within .002 of the finished size & hand filed the remainder to get a snug bearing race fit.... A tedious setup, but beats hand filing the whole thing...

It took the better part of fifty years having the inner race spin on the shaft to get about .050 wear. I hand file it so there is an ever-so-slight interferrence fit to the inner race to keep it from spinning. The fix will outlive me. I would upgrage older solid bushings that eat up the spindles to flanged ball bearing... 1 1 Share this post Link to post Share on other sites
Lee1977 7,578 #5 Posted March 5 (edited) Even if it wears. brass won't wear as fast as steel. That why they make bushings out of brass. Edited March 5 by Lee1977 2 Share this post Link to post Share on other sites
