Yip is a great guy and makes an outstanding product, but he can be a bit, how should I put it... "over the top" with regards to insuring that your spindle to pivot distance and effective length is exact.
It took well over a month of back and forth emails and even sending numerous photographs of my setup to convince him that my Jelco arm did, indeed, have an achievable effective length of around 235mm.
The MintLP protractor is painstakingly precise and I understand Yips need to get these measurements as close as possible. However, a millimeter or two +/- on spindle to pivot distance can usually be accommodated for via the headshell slots.
All that being said - trust me that it'll be worth it in the end. It's the most precise protractor I've ever used.
