I have the Woodcraft, and it works just fine.

I disassembled the whole thing, degreased it, and reassembled. Also
had to move the base over (per instructions, which were good) to
adjust to track to blade spacing for my 1023SL.

When I had the thing disassembled, I took the opportunity to lap the
base of the jig, and clean up the rough spots from casting. I'd
strongly recommend this tuneup step to anyone using one of these jigs.
It now glides on the saw top without leaving any marks or scratches
whatsoever.

This jig goes on sale from time to time, and is a good value.
