Thread: jig for loose tounge on mitreed corners

Mitred corners and loose tongues? I don't know what this means. Do you mean splines cut into the corners after the box is assembled? If so, the cuts for the splines are often made on the table saw using a simple jig to perch the box at 45 degrees to the saw table and then put across the saw. Say more if I have misunderstood what you are asking.

Do you mean what I'd call 'keyed mitres'?

There are a number of ways of inserting a spline in a mitre joint and I am sure on the forum there must be someone who has attempted the joint. With the Drop saw and a Biscuit machine it would be quite easy. you didn't say what tools you were going to use and what experience you have with the router.
Personally I have cut the mitre with the router and also inserted the spline. Routing the spline slot when it was in the Jig so that it came out complted. This required some great knowledge of how to use the template guides and the making of a simple Jig to hold the material.
I have used this system when I was supervising Blind people when we were making small tables some three years ago. They, the blind people were able to produce the joint under supervision. "It is not an easy project for anyone with limited knowledge on the use of the guides."
I have enclosed pics of the table and the joint used at that particular time. I have since altered the joint to adding a Tenon to the Mitre, again using the same original Jig with some alterations. (pics enclosed for your interest).
I have yet to write up this article at a later date. 'Routing Mitres and Inserting Splines' This will then be added to my collection.

I made one of these to use on a tablesaw, minor changes only needed to run on a router table, (less depth of bottom plate)
