I recently bought A Rockler jig it mortise jig, Ready to use it to cut a hinge mortise but the mortise jig will cut into the aluminum jig sides the way I set it up. Bit is slightly bigger on the end than the bit bearing. I can use some help on how to use jig, Thanks.

Hello, i am not familiar with it, but the bearing has to ride on a fence, and not touch anything except the wood tour trying to cut. I am sorry, ernest some bits can have the bearing replaced with a larger one. You should have gotten that with the bit, r should be able to replace it, i would think. Someone will be along who can answer the question, I hope, Good luck.

A mortise bit was included. The bearing is 0.5 inch and diameter of the flutes is 0.5 inch but one flute is slightly wider than the other flute so the bit is useless because it will scrape the jig. E-mailed Rockler but have not received an answer yet. I live in Northern Minnesota right on the Ontario border. I retired recently. Worked for Minnesota. I am making clocks for my six children for Christmas. Need the mortise jig for hinges on the clock doors.

Rockler didn't answer my e-mail. Rockler instructions for jig-it are just to assemble jig. I bought a Diablo hinge mortise bit. Cutting edge is 1/2 inch and bearing is 5/8. Tedious to set jig to compensate. Jig-it is not worth $91, I am going to make plywood jigs for different size hinges. Wasted my money.

Hi ernest

The jig works very well with the right bit, I made my own copy in two sizes but the key is the bit..,,one for very small hinges and for the big hinges :)

The bit I use is below
