In this picture you can see that I have faced the jaws of my vice with two maple blocks and held them in place with electrical tape. Both wood blocks have holes in them to accept the shaft & keep it in place. The holes and blocks are also centered perfectly over the center line of the vise jaws.


Vises are not the most precision instruments therefore it is imperative that you line everything up so the jaws don't cock one way or the other when you tighten down on the shaft & bearings. The bearings must go on at a perfect 90 degree angle to the shaft.


If you look closely you can see the pressing washer.
