Project Information

This jig works in conjunction with your router and its edge guide. It has a fixed stop on one end and an adjustable stop on the other end to limit the length of the mortise. The guide helps to support the router and keep it square. The tabs on top of both long pieces of the jig make it very easy to align it flush with the workpiece. You can use this on any length workpiece, short or long.

If the mortise is closer to one end of the workpiece, and you need to make several pieces identically, then you can add another adjustable stop, so you can easily get repeatable results. See photo 3.

If the mortise is wider than your largest bit, then just move the router to the other side of the jig with the stops in place and cut the other side of the mortise slot.

The mortise jig is made from 1×3 dimensional lumber, so really 3/4×2.5. It is the premium pine from Lowe's hardware, and it is very straight. I glued two together for each rail. The length is 24 inches.

That's really cool. I keep meaning to build a mortising jig. This has given me some ideas already.

Thanks Pete, I think my brain works that way. I like puzzling over an idea and stripping it down into the simplest elements.

Scott:

1st - nice work - I'm going to try to replicate this, if you don't mind.

2nd - while I am very interested in you jig, there was an advertisement for T-Shirts - to the right hand side of your post - which was particularly captivating. Perhaps we should ask Lumberjocks to post our work with dull and boring advertisements … less competition for our diminished attention span.

MJCD - Yes, help yourself, I hope you like it.

I too have seen that ad, so I know exactly what you mean. It didn't stay for long, so they must figure the Home Depot ad sitting there now is just as appropriate on this website!

sawdustmaster - Wish I had that kind of time. Man if only my project list would shrink, but I add to it faster than I crank them out !!!

What is picture three of? And what does the dado do in the right side of the jig in picture four?

Thanks,

Milo

Milo, in picture three it shows the stop that you can optionally insert. If you have a very long board with the mortise in the middle of it then you would just remove the stop, as shown in photo 1. If you have a mortise near the end of the board then photo three shows that you can just press the board up to the stop. Cut the mortise, then if you have more boards with a mortise in the same place, just insert the new board and press it against the stop, and you are ready to cut another mortise without doing any measuring.

In photo 4, on the right side of that photo, that is the stop that is shown in photo 3. I just slides in a groove and tightens with a knob on the outside, and the stop rides on the inside.

I hope that explains it, let me know if not.

I could have used this on my last project - would have saved me guide bushings and the router bits I ruined using the Guide Bushings. Also, this ould be foolproof, once you've used it once or twice.

Very nice. Very Useful. The need for such a jig could easily arise and now I know how to do it. Thank you.

Wow, that is an old router. I have the same one stored away someplace, because I nearly wore it out. I bought mine back in the early 80s!
