Free ARC Protractor
If you want to print a custom ARC protractor for your tonearm there is a wonderful link on Vinyl Engine to Conrad Hoffman's ARC Template Generator.It is a windows program and is small and excellent. You can specify any Pivot to Spindle distance and any Inner and Outergroove Radius based on your desire and get a printable ARC with a calibrated line to make sure the ARC is printed to Scale. I recommend an Ink Jet printer since if you print on heavy stock paper a laser printer will curl the paper.
