How to choose the right protractor for my effective tonearm length

Hi, I have 2 turntables that I want to align correctly. TT-1 has an effective tonearm length of 223.5mm and 19mm overhang, and TT-2 has an effective tonearm length of 215mm and 15mm overhang. I currently have a Baerwald standard protractor that was made in Great Britain. It says the Vinyl source on it. And have a basic mirrored Stevenson protractor. Please I need help. Thanks!

The Conrad Hoffman Arc protractor is free, customizable, dead accurate, free, easy to use, only 1 point to make parallel to, free, and you can choose your radii for standard DIN, JIS, IES, RIAA, and choice of 3 alignments. 

Line up to the arc, make parallel, done.


Did I mention it’s free?
