Next Q though Dave: what sort of a device would one use to map those errors with? In my teeny little India made hundred dollar table, you know the errors have to be considerable. OTOH, while sharpening a table saw blade, I would estimate the calculated tooth position and the factory tooth were within a thou at the rim of a 10" blade, well within my ability to center the blade on a tight fitting arbor. My biggest problem is the backlash, which made it cut very tight sprockets. But they worked anyway. ;) >On Sun, Mar 28, 2010 at 10:22 AM, Chris Rhodin <ch...@notav8.com> wrote: >> Hi, >> >> Is there a way to compensate for a periodic position error?
