Ed,

Everything you said makes sense. BTW, I know I got within .001"
because I used, ahem, a dial indicator that I purchased later. g I
don't own a purpose-built TS alignment tool, but I have found that the
ol' magnetic base dial indicator to be a valuable tool.

On a separate note, I have a link here that has proven invaluable as
far as tablesaw tune-up.

Hope it helps somebody, anyway.
