I might have found an option for an A-Sized bearing blank. Its an unthreaded spacer from McMaster Carr, and the dimensions are super close.
The only issue is the ID specs are 5.3mm -0/+0.3mm, which sounds like it would fit loose. Anyone have any thoughts? Or know where I can get an A-Bearing blank?
This doesn’t really answer your question, but Ed mentioned in the fixed axle discord that he had previously enjoyed playing with just the inner ring of a broken A bearing. If you just had a spare A bearing laying around that you don’t mind destroying, you could give that a shot.
Thats not a bad idea at all, I have a spare bearing I wouldn’t mind breaking. I have a set of rubber shielded A-Bearings I use for most of my A-bearing throws (most are responsive so it helps keep them responsive longer)
I would think a spare A size bearing and some super glue or a few dabs of JB Weld could yield a similar result as the blank. Lock it up. You know it will fit perfectly.
thats actually genius. thank you!
