Oldedges sent a Bolt to me to be hubstacked. I wanted to leave as much ‘Doc Pop’ in the yoyo as possible, so instead of gutting it and building a new bearing seat with the hubstack, I decided to machine the nipple on the hub down to the brass spacer
Before
After
I then machined a piece of 3/8" aluminum rod down and tapped it to accept a 6-32 axle
Which I threaded into the yoyo
After setting up on the lathe and machining, voila!
Of course I had to finish it off with some matching Ricestacks!
