Captain_winters,
First off, I'm going to put my tail between my legs and admit I was wrong about the S2P distance. After re-measuring it again with great care and a friend's help, it is indeed 258 mm. I think I didn't account for the difference in the height angle between the spindle and pivot.
Now, the info you provided is awesome, and pretty much what I've found as well. I do believe Yip uses Bearwald so the overhang should indeed be close to 15 mm as you stated. I think VPI uses their own geometry, which is close to Lofgren B, but not exactly it. The Vinyl Engine article I linked to explains it in more detail. A few years ago I had a conversation regarding protractors with Mike, and if I recall correctly, he said the VPI jig was designed to minimize distortion in the last 1/3 of the record.
As far as the Mint not fitting over the spindle, I initially had some difficulty fitting it as well, but after working it a little, it eventually went all the way down snugly and now fits perfectly. I guess it does not matter now since you fixed it anyway.
Once again, thank you all, especially Captain_winters, for your feedback and contribution to this thread. There is a lot of great info in it that will hopefully help many others.
