Topic tags/keywords: jig question resource router chisel joining milling

Back in 1992 I attended a wood show at Anaheim Stadium where I saw this Rid-A-mortis jig being demoed. I remember my Father-in-law and me watching this guy cut tendons like they were nothing. We were so impressed we split the cost and bought it. 17 years later I opened the box to check it out and set it up.
Well wouldn’t you know…I can’t remember how it works? I can cut the mortis but the tendon I can only cut square when it should be rounded off like the mortis. That was the beauty of the jig, not having to chisel the mortis to match the tendon. Did any one else buy this jig and can offer me some help?
The company I believe is no longer in business.

It takes a long time to build up the courage to make a mortise and tenon.

Or he is so old the memory of it just came back.

Apparently the name was the Miller Rig-A-Mortise.

PatentNonsense,
The router base that came with the kit is just like that which works well to make the mortise.
But the tenon jig is the one I’m having trouble with. I’ll take some pictures of it tomorrow and post them.

The manual came with instructions for building a morise jig and a tenon jig which are used in conjunction with the base. If you PM me with your info I could get you a copy of the manual.

I googled Rig a mortice and found this note on a blog there:

i beleive i saw the jig he described in an old woodworking book i checked out from the library. it was called a “rig-a-mortise”. it doesn’t seem to be made anymore. you can make it yourself…check out this link: http://www.woodworkingtips.com/etips/etip032301wb.html

This is the same as the note above.
What if you made a jig to put over the end of a board to make the teneon that uses a guide bushing to follow a template of the tenon shape you need. It could clamp on the board and have a guide that sits at 90 degrees to the part with an oval hole in the end.

I did google it but could not fine the actual company that makes it. But a guy from another woodworking forum had the same jig and sent me the instruction. Jim you link is basically the same thing. But this jig also makes the tenon which I dont use. I use the floating tenon it’s a lot easier for me.

How does the floating tenen work- like a dowel going into two pockets?

You got it, I saw David Marks on the Woodworks TV show and he tends to use that technique a lot.

I have found a Rig-A-Mortise II jig. I has a manual and some other instructions. I don’t know if all the parts are there but let me know if you are still interested?

Thanks for the offer but I did manage to get a copy of the manual. Have you used your jig yet?
