Rectangular Glue-up Clamping Jig

Yes it may look like some bizarre English tea tray but I assure you its a jig.

Most of the patterns I make for my box tops are relatively small, up to 100×200 mm (4” to 8”).
Fiddling around with big clamps at glue-up time is a regular pain in the butt so I’ve come up with this.
It’ll clamp anything rectangular up to the above sizes. The M6 (1/4”) x 50mm (2”) bolts on two faces are threaded through M6 inserts and supply clamping pressure to two disposable floating jaws (in this case MDF).
The floating jaws are not attached to the bolts, just pushed inward by them.

The clamping range of the screws is only 50mm so you make up the floating jaws to a size that will take up the slack.

Materials are MDF (base and floating jaws) and Oak (frame sides). The whole issue is oiled to stop glue sticking to it. An alternative would be to line the thing with cling film (Serran Wrap) but this would again be fiddly.

By the way if you have a very small pattern and you want to re-saw it into several slices after its glued up, it is a good idea to glue one of the floating jaws to it. Then you can use this ‘extension’ to hold it and add stability whilst you are re-sawing.

It can of course be scaled up to any size

I like it!

How do you keep squeeze-out from gluing the box to the jig? OOps… maybe I should finish reading the post. LOL!

Thanks, it’s really useful for repetition

By the way oiling the face of the floating jaw so it wont stick is a good idea too.

I like it very much. A simple jig that works and is a clamp saver.
Best idea since clotted cream.

I like this. I may make one myself.

I think I would use wax paper to prevent the material from being glued to the jig. For me, waxed paper is a little more manageable than cling film.

Great idea. Does the oil transfer to the wood your are clamping and stain it? I use wax paper and cling film

There may be minimal transfer. I resaw, sand or otherwise rework my box patterns after glue-up so this is not a problem usually.

Very cool. I make a lot of tiny boxes and struggle with the large clamps. I have been using rubber bands, but this would help keep them from twisting
