Mint Protractor for the Classic Toneram 10.5i-SE

For the VPI Classic 1,2 and 3 series and the 10.5i series, Mike at VPI has confirmed the correct S2P distance is 258mm for an effective length of 273mm.

Actusreus, I suggest calling VPI. After reading your post, I recalled my email from VPI and my info is correct based on the email from Mike.

With respect to the MintLP, Yip fabricates the protractor based on the information that the "end user" provides him. VPI has confirmed that the info on Vinyl Engine is wrong. I would not be surprised to learn that a lot of MintLP protractors have a S2P distance of 262 based on the incorrect info on VE.

VPI has also confirmed that the overhang is 15mm, therefore, just add that to the S2P distance to get your effective length. S2P 258mm + 15mm = 273mm effective length.

Again, all of the above info comes directly from VPI

The VPI jig will produce a different null point than the MintLP because VPI does not use one the 3 generally accepted geometries. Also, the VPI jig is expandable and is not fixed in length; therefore, it is absolutely useless in determining or measuring the correct S2P distance. The S2P distance must be first calculated correctly, and then the VPI jig is adjusted around the bearing housing and spindle.

Actusreus, I don't own a VPI Classic table. I asked VPI about the S2P distance in order to mount a VPI JMW Classic 3 arm on another table.

A friend of mine just purchased a Classic 3 and his S2P is 258mm.
