Last weekend I broke the inner arbor wrench (the open-end one) for my
Unisaw. Evidently these have been out of production for a number of
years and have become near-unobtanium. In case anyone else does the
same dumb thing, these people have them (I bought a second for a

Talk to a CNC water or plasma guy and with good dimensions a nice one
can be cut out.
I made a nice 2" unit and had small circles in the back corners
to take the dirt when the wrench is pressed on. I wanted the back

wrench for the new Unisaw doesn't fit the old (too thick).
