Greetings all; The screws I have to put in this "used to be a micromill", are 8mm2.5's and have an outer diameter of about 9.25mm.
I intend to turn them down to 8mm to fit in the existing bearing bosses, but with ball bearing thrust washers with an 8mm bore. But in grinding them down, its obvious I wall NOT have a good shoulder because the 8mm is just about the bottoms of the ball grooves. This means I will not have a good shoulder all the way around, and that implies that the ball thrust washers may tip. I am inclined to make a sleeve about 12 or 13mm OD, and at least 10mm long, and a bit small so I can heat it and hopefully drive it against the shoulder, and that it in turn will prevent the thrust washer from tilting. That would involve driving it around 80mm from the end of the screw. No clue if a shrink fitted sleeve could be driven that far in one blow of a dead blow hammer. But I don't have any better ideas ATM. Anybody else have an idea to offer? Thanks. Cheers, Gene -- "There are four boxes to be used in defense of liberty: soap, ballot, jury, and ammo.
