Domino clamps
« on: April 17, 2018, 05:31 AM »
I need some clamps to make a new 2m long table top. Do I invest in at least 5 long clamps or do I...  [big grin]
Why does the stockpile of white+green boxes grow? It started with just 1, now it's over 26...

Interesting idea to use the bending of the clamp for holddown.

Might be easier to put another domino hole horizontally through each side block (or the bottom somewhere between the side blocks) so you can use the clamp normally, should give higher / more even pressure and be easier to clamp.

Not sure why an extra horizontal hole would make it easier to clamp. The clamp pulls the 2 wedges together. With more pressure the wedge comes closer to each other and their base move further away, thus giving the pressure needing on the workpiece. Additional wedges might be installed under the horzontal bar in order to get downward pressure (keeping the pieces flat). Maybe the horizontal bar should be a T shape...

Now that you spell it out for me... my brain failed to register the wedges for some reason so I thought that this is vertically clamped. Must have been to much sun for me the last days (now that it's shining again), sorry.
Nice design, now that I get it  [embarassed]

This thread gave me an idea of how to solve clamping of a triangular table base I am gluing up shortly...
Thanks!
