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

Hello

I just purchased a wally tractor universal. On it is an arc for rega arms with an effective length of 239 mm. I have an origin live arm, the OL specs are spindle to pivot distance 223 mm and overhang 17.24 mm, effective length 240 mm. Being a newby do I then shoot for a spindle to pivot distance of 222 mm and use the 239 mm arc or aim for 223 mm P-S and use the 239 mm or another (241mm) arc?

Thanks

Thanks . I'm assuming the general principle is to have the stylus track the (in this case 239mm ) arc somewhat irrespective of the exact manufacturers specified distances. This would imply that other arcs are equally acceptable if possible, limited only by the design of the arm/headshell/cartridge.
