Inspired by some images online when looking for some edgeclamps, I decided to have a go at trying to make some out of scrapwood for as low cost as possible.
Bessey KF2 onehanded clamps looked like a good concept, so this is kind of wooden version of this.
This is of course no substitute for this great clamp, by any means, but a fun project that can come in handy.
The pressure applied on the edgband is of course limited by the strength of the wood, and can not be compared to the metal one from Bessey or other similar.
This one I would believe is most suited for thinner edgbanding acquireing low to moderate pressure.
The clamp is made out of 9mm and 18mm baltic birch plywood.
Top and bottom part is 9 mm, and center filler is 18mm.
Cams are 18mm ply thinned down to aprox 14.5mm to make room for the homemade torsion springs.
These are made from 1.25mm x 120mm piano wire.
2mm rubber is glued to the cams with epoxy for good grip (it might be even better with 1mm, but I had 2mm laying in a drawer nd used what I had.
The plan calls for 10mm (or similar) threaded rod, but I had a 12mm, so I used that. You may feel free to use any size if you choose to download the plans and build your own.
The threads are cut directly into the baltic birch plywood, and seem to hold up. If this doesnt seem to hold up, Ill put in a threaded insert ut of some kind.
Same goes for the pushpad. The diameter has to be adjusted to fit the nut at the end of the threaded rod.
I used a 24 mm wooden dowel for the handle, and bought a bicycle rubber handle for $1.40
This was a fun project, and i will be making 6 or 7 more to keep the prototype company
Claiming the cost of this is $3, is based on estimates adding the 1.40 for the handle and aprox 1.60 for the threaded rod, 1 washer and 2 nuts, and mabye some pianowire. The wood is only from scarps.
Hope you enjoyed this post, and if you decide to try and make your own, there are Sketchup plans available:

Please bare with me, my sketchup knowledge is limited.
