The more I’m reading…the more I think I am wrong. You are not suppose to put o-ring down the spindle shaft but instead actually in the bottom of collet. But then, I read about using dowels. Surely, dowels would land on the bottom of the spindle shaft.
PS: took longest shaft router bit I had (in the picture way above on the left). If there was a o-ring or washer at bottom of collet, cutter head would be over 1/2”-3/4” above collet. Unsafe. Also, re-reading internet posts about the subject, I think there is confusion with vocabulary between bottom of spindle shaft (aka bore) and bottom of collet.
Yes Rich…I would strive to do as accurate repeatable setups as possible while always doing a test cut in the end.
