Ever since I got the Ariston and saw the threaded spindle I meant to try. Liked what a clamp did for my VPI HW-19 long ago.
Pretty easy, cut the Macassar Ebony disc with the Jasper Jig and the holes with a forstner bit. I had planned to cut the hole just under-sized and pound in the nut but I didn't have the right size so some epoxy carefully applied sealed the deal.

The sound might be a little more focused, whatever that means but I think it looks cool and 'I made it'.
