A cat made me do it.
Welcome to the forum.Does anyone have any experience or knowledge otherwise about the Wixie WR750 system? What is the length of the fence itself? Would it work on a 22" deep t/s table?
Looking at the above link and the owners manual available there I don't see a length for the fence, odd that they don't have it. 27" is a very common depth for table saws, the fence should do well for a 22" table. If you email or call Wixey they should have the number for you.
Please post your saw brand and model, maybe a forum member will have experience with it.
