There’s a small bearing 888 on our bst and I was wondering if it would be possible to mod it. More specifically, I’m ruining of swapping axles with a pgm so that it will accept a C-sized bearing. Anyone every try this? Thanks in advance for any thoughts

That won’t work unless you have the means to remachine the bearing seat to accept the larger bearing. Which is more effort than it’s worth IMO.

Ah, you’re absolutely right. I didn’t think of different bearing diameters. Thanks, dude!
