Default mortise & tenon jig

I thought it would be nice to build a all-in-one plunge router mortise & tenon jig. The jig consists of a plastic sheet mounted on a wooden structure, on which the router moves in four directions. A 4 mm thick plastic sheet was chosen: a. because it very smooth. b. it is thin enough to be strong - and yet does not "steal" too much of the bit cutting length.

As can be seen in the photos + the YouTube link, the travel of the router is limited by three sliding fences, located in specific distances marked on the measure-tapes. Those distances were set regarding the desired length of the mortise (and tenon) and the thickbess of the tenon. The left side is fixed and needs no sliding fence.

To make the mortise, I clamp the stock using two clamps, and move the router from left to right. To make the tenon I clamp the stock using a sliding fence, which guarantees it's perpendicular, and then pull the router towards me, then right, than push onward, then left, always keeping the router base in contact with the fence.

I made the base of the router (using the same plastic sheet) perfectly round, so the distance from the fence to the bit is always the same, no matter the position of my hands holding the router handles.

With some experience I achieved excellent results.

As a newbie in this forum I am not allowed to post the URL. So, if you want to see the jig in action, please search yair_fe in YouTube, and there you'll find the mortise & tenon jig, and two other jigs.

Hello Yair

Looking at your video again and again I don't understand how you do the settings for a particular size mortise or tenon.

If you have a chance, it will be nice to explain this

Thanks
Nicolas

Hi yairfe

Very Nice job on the jig

It's looks like a mix of the Craftsman and the Trend® Mortise & Tenon Jig, I do like jigs alot , here's a small tip,,,if you use one of the small bar clamps and remove the small stop pin on the end of the bar you will not need to look for it all the time it will just be in the cabinet sticking out..no round hole needed to put it in place just a slot like the Trend type..

Very interesting! I've not used YouTube much before and started to explore further. It didn't take long for joints to become joints, if you know what I mean!

Thank you for posting the jig.

Cheers

Peter
