First of a big Thank You for all the replys on my last post !
This clamping system has been on my mind for some time and yesterday I set out to put it into reality as I started a box and thought I put and end to the frustation of clamping a box and still get the odd box that is out of square and have to rework it .
This clamp or clamping jig is a breeze to make and also minimal in cost aside from the Bessy clamp which I will use for other things anyway .
The design idea has several criteria which are simplicity, low cost ,accuracy ,visibility of the corners during clamping and smooth and accurate operation and no damage to the corners, I thing I have met that goal .
I started with some plywood squares cut perfectly square and pinned two of them face to face and layed out the three hole loctions and set up the drill press with a stop block to ensure all the holes where in the same location on all four corner pieces . This was followed by cutting out the right angle piece which contacts the box , the cuts were made with my table saw sled and have to be a perfect 90 DEG.

The steel pins are made from a piece of drill rod and the copper spacer sleeves are 1/2” copper pipe cut to lenght .
The copper sleeves serve a dual purpose as spacers and also as rollers to let the strap slide smoothly as clamping pressure is applied
The strap is nylon from a hold down strap and the clamping arms are again made from Baltic birch ply .
This clamp can be used on a multitude of box designs by altering the corner shape to accommodate dovetails or finger joints etc.
The box that I am making was cut on the sled also and I did a blog and video you can see here

I included some random pictures also and hope you find this interesting and enjoy the video .
Any questions and comments are always appreciated .

Great idea, I have been searching for a cost effective way to get more box clamps for my students to use. Could you post a picture of the 2 clamp bars from the side, I plan on making one tomorrow and am curious how much material is left at the bottom. Thanks for sharing.

Nice,
And when you do it I’m sure it’s square. I used that nylon strapping as webbing on my sofa last year, there is stretch to consider?

Nice idea and design. Thanks Klaus. This will surely be a great addition to my tool/jig addition in the very near future.

They are too easy to make and I won’t waste more money on a patent ,I have one on my Dowel Tail system and will never make money of it just a waste of time .
If I approached a manufacturer they would just tell me that they already have something similar and will marked it soon .
Just make one for yourself and don’t wait for a manufacturer .

Good looking clamp Klaus. I use a ratchet version from HF that is very similar ….. but yours is free and very efficient.
I also like yours just for being shop made. Good elegant tool making, thanks.

Gee wiz more good stuff from Kiefer! I see you have been busy brain storming and inventing good things again. This is a really useful idea you have created Klaus. Looks like a nice way to clamp up a box. Nice work!

I like it much better than a ratcheting system.

Klaus, that’s a great little idea there. The serpentine strap wrap seems to be the trick. I also use the ratchet version from harbor freight but this looks more versatile. Well done.
