MintLP arc protractor

I'm talking to Yip about a protractor for a Rega RB-300 mounted on a VPI HW-19 Mark III. To verify the desired 222mm spindle to pivot distance I cut a piece of cardboard 222mm in length. I measured from the spindle to the center of the armboard mounting hole. It looks to be spot on at 222mm. Is there a more accurate way to measure so that I can confirm my initial findings?

Johnbrown's suggestion is perfect and exactly what I did with my setup when ordering from Yip to insure everything was going to work with the parameters I provided him.

Got my Mint protractor yesterday and checked my alignment then and again today.... It is "spot on" across the arc. Seems that I either did a damn good job using my various tools or just "got lucky."

Don't know whether to feel gyped or proud. :-}

Just think if it this way, Doak. Now you have a tool that can provide repeatability. :-)

Oh, and don't stop at just getting the arc correct. There could well be more improvements waiting for you.

Doak,
I found that I was close to being on the arc of the Mint with my SME protractor but cartridge zenith (rotation) was way off. Dan ed is correct to suggest to also check cantilever alignment at the null points using the Mint.
