I’m working on a design for a combo bookcase w/blanket storage and am going to use mortise and tennons for some of the joints and have had the plans for this mortising jig for over 4 years just waiting to be made. It’s from the April ‘05 Workbench mag. I just couldn’t see buying one and this seemed like it would do the trick. It seems to work very well. With a 3/8th” bit the mortise can be up to 6 1/2” long. You can use any size bit that you need. I was just trying the jig out with some scraps and the 3/8. The last pic is what I’m using to cut the tennons.

The jig has quite a bit of adjustment capabilities in moving the router in and out plus the size of the material being used could be quite large.

Some of the knobs and the hold downs I made myself. Sometimes I have a little too much time on my hands and plus I’m Cheep.

Thanks for the comments guys.

moshel, so far it seems ridged enough. I was worried about it while I was building it and figured if it wasn’t, there is room enough on the back to put a couple of gussets.

Nicely done. Your attention to detail is shown in how you made your own knobs and hold-downs. I really like the tenon fence and am thinking I should make one.

Great looking and functional jig. I might have to copy that myself.

Thanks again guys for the comments.

I forgot to mention that the horizontal material support can also be rotated vertically to route a mortise in the end of a work piece. This feature is what drove the height of the jig which is about 14”.

Nice work, the jig looks like it should hold up quite well. I really like the home made hold downs and wing nuts, I have made similar ones for myself. They’re fun to make, work very well, and like you said, cheap.

That is a well thought out and cleaver tool that you have built. The router base that the router mounts to, is that a mount for a router table, and modified by you! I like it a lot.

olddutchman, thanks for the comment. i can’t take credit for the design (wish i could) but it’s from Workbench Mag. the base for the router is custom for my router from a piece of phenolic hard plastic ordered from Highland Hardware.
