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
to fit tightly and not be displaced.

wrench for the new Unisaw doesn't fit the old (too thick).
Bummer.... You also might consider buying an inexpensive Harbor Freight
or Northern Tool open end wrench and grinding the face to be narrower.
I did this for out Kitchen Aid blender drive sprocket. The wrench had
to be less than 1/8" thick.
