@stringreen Yes, I have a Prime. If I'm not mistaken I remember you from the old days on the VPI Forum, how I miss that, a treasure trove of info. Shortly after I bought the Prime they shut it down, really hurt, if I would have known I would have copied so much of it. Have crossed paths (actually always looked for Brf) with Brf on another forum but never figured where he hangs his hat these days.
But, he contributed on a forum where I learned all about the ruby tip/skate plate and all, so I did that upgrade. He also posted on the % tracking force to apply (and how) to the additional pivot as well as using the pivot to adjust Azimuth. I did the whole Sota motor,Condor & RoadRunner upgrade (this was from readings on VPI Forum at the time), and many other upgrades to now. After this final tweaking to the setup I will finally use the Prime table (original motor never turned on). On & On I could go-
Anyhow, I've read many of your posts, mostly here and there and have to say were a big influence in my decision to enter the land of Foz-
Take care everyone-
