Thanks, man! Much advice was shared with me when restoring my table and I did a ton of my own research about these tables along the way. I'm happy to pay it forward.
Those machines spin the balls too fast. There's no need for the platter to spin more than 500 rpm. Faster spin = more friction = more heat = potential for ruining a ball. No thanks. High quality pool balls are expensive. It's not worth the risk, IMO.
One thing to be aware of when powder coating old cast parts: outgassing. There's gas trapped in the casing which gets released through heating it up during the powder coating process. Some of my pieces had to be done multiple times. My coater didn't charge me extra but yours might. Just an FYI.
Nice! Did you adjust the angle of the pocket openings? When pockets are reduced in size, it's sometimes necessary to alter the angle of the pocket cut so they aren't too wide. If they are too wide, you'll be left with the Olhausen Rattle. What are the pocket angles in the corners?
