Just thought I’d post this jig, for clamping triangular glue-ups. As you can see its the one I used on the box tops for the Kaleidascope boxes.

It consists of two pieces of Sapele, re-used from an earlier mitre sawing jig, with their ends cut at 30 degrees.
Giving an included angle of 60 degrees. These are screwed to a piece of 12mm MDF and cross screwed to each other at the sharp end (to avoid them seperating). The end 2 or 3 cm of the whole assembly is then sawn off at 90 degrees giving a flat for the hand-clamp to sit on. The back end of the hand clamp sits on another piece of scrap MDF, spreading the clamping pressure on the glue-up evenly.

David

Do you clamp up to 90 degrees then or just 45 or so? Only reason I ask is that I was going to try 90 degrees but was afraid that the pressure on the glue-up would not be even enough.

usually to 90 ,
then 180 ,
270 ,
360 .



i don’t ‘pressure clamp’ them ,
but use the arm to ’ radius ’ them to the right place ,
then bevel bottom stops (removable later ) ,
to hold them there till glue is set .
you can tap them around until all are in place ,
if you have some slower setting glue .

Thanks David. Like all good ideas. Simple but effective.

Cozmo, don’t feel bad. Ignorance means you just haven’t seen something yet.

Experience is best when its shared.

By the way this jig also works for the Tapezoidal box tops in ‘Vanishing Point’ but you need a triangular blanking piece at the narrow end of the design, when clamping.

Seeing work like this makes me think I need a new tool, namely a better quality, larger brain. If I find one, I will do a review on it. Thanks for sharing your secrets with us.

So simple yet so effective… as are all things once you think them through.
I thank you for sharing your ideas and jigs..
I have a similar set up for hextagonal boards….ie for tumbling block trevits etc.
