Alignment Snafu? Or?

Hello all, I am about to order another Protractor, this one an Arc Type from Ken Willis over at the Asylum.

Ken has asked if my arm was at 210mm, or 211mm Spindle-Pivot Distance, and taking an actual measurement this evening, I actually find out my arm is mounted at 212mm. So, may I ask what should he make this Protractor for, 212mm? Or no? Will 1mm make a critical difference in accuracy, and sound? I will forward this info to him as well, and see what he says. More input, and advice is of course better. Thanks, Mark

Just wanted to add, the suggested Spindle-Pivot distance for the AQ PT-8 Arm is supposed to be 211mm. Mark

MArk, it's important to know the exact spindle-to-pivot distance this arm was designed for. It's part of the overall geometry.
If you're sure it's 211mm, then align to 211. Regards

I think you want the protractor made to your actual mounting distance and adjust overhang accordingly.

My documentation shows a spindle to pivot distance for the Audioquest arm of 210mm.
