Has anyone ever tried to tap a #10-32 or a #10-24 in a yo-yo with a C size bearing? I have a yo-yo that has completely stripped on both halves which I want to try and salvage. Any suggestions?
The bearing size really doesn’t matter. The original axle size is the key. It should work if you pre-drill it to the right size for a #10 screw. I would also recommend using a lathe so that everything is centered and aligned properly. Doing it freehand is iffy.
I should add that I work in a shop and that I will be doing this on a lathe. My main concern is that the OD for a #10-32 is .190 while the ID for a C size bearing is .250. That only leaves .030" per side of aluminum on the bearing seat. That just seems super thin to me and I feel like it would crack after a few throws. But, I am not 100% sure on this so I thought I would ask if anyone has tried to tap a #10 and if it worked well, or bad for them.
OK, if that’s your concern, it’s not an issue. Early generation dif-e-yos and most all of the anti-yo yoyos came with 1/4 in. set screws for axles and most all of them used the stock “C” size bearing. It really doesn’t matter if the axle touches the inner race.

OD on an M5 axle is right around .190" I think you’re clear
