Have you looked at VinylEngines arc protractors ? Big thing with them is to make very sure you printer doesn't scale them and create a error - they all have a scale built into them that makes this easy to check.They are free - great turntable/arm/cart site.
CARTRIDGE SETUP
Grrrrrr.. can I say it again.. Grrrrrr...
I dont consider myself an idiot but maybe I need to re-evaluate.. OVERHANG.. is killing me.. I bought the GEO-DISC over 20 years ago. It has worked within reason I guess but wanted to make sure that the setup was accurate. Having the LINN and ITTOK there isnt an easy way to identify/lineup the pivot point. The arms center is offset so.. I have printed several protractors from LINN sites and have researched how to implement but have left scratching my head. They dont lineup/match the GEO.. not even close. Once the overhang is adjusted where I "think" it should be (using the GEO-DISC) I try to line up the azimuth by using the GRID on the GEO.. The second validation is assured by measuring, with a very high quality pair of dial calipers ,from the back of the screws that are mounting the cartridge to the head shell to the apex of the slots that are machined in the head shell. The measurements between the two screws to the back of the slots are within .001. Close enough.. But the BLACKBIRD still has distortion on some of the cuts. I am very perplexed. I can purchase a protractor but not sure if it will get me any closer. I like the one that is being sold here but it's 700.00 a lot of money that could be for nothing. I am pretty sure that there is nothing in the equipment , i.e. arm , table, BB, phono that is causing this. The BB is VERY quiet..
So the burning question is , what is the best setup tools and methods that you use to SETUP the LINN with the ITTOK arm specifically.
