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:

Cams are kick ass. I haven’t seen this style of clamp before, very cool.

I have seen those, needed those, got by without those ... but now that you showed how to make those, I can make those myself!

Nice job, anytime you can make it yourself you are better off both money and fun!
Are you willing to share the Sketchup file?

Thank, good work.

Very nice execution. I’d be interested to know how they fare in practical use once you finish building the rest and put them to work. Sure looks like it’ll do the job for any moderate banding jobs though. Thanks for sharing. About how long did it take to build it?

Fantastic. Thanks for sharing. I’m curious to see how much force these could exert with a threaded insert. I’m guessing it would be enough force that it would be necessary to add rubber from an old bicycle tire to the cams and pusher to prevent marking the workpiece!

Thank you so much for the positive comments guys:)

@oldnovice: you can download the sketchup file from the link in the text below above.

@Tdazzo: I`ll write a post here once I have put them to use, hard to say, but I would guess about an hour or 2 excluding the glue up time.

@twoblacklabs: I have been thinking about some pictures from my shop/shop tour, but never seem to find the right time, I always want to wait until this and that is finished, but I guess that with our shops always beeing in constant evolving, there is never a “right” time. I might just yake some pictures and post on my profile

@Nicholas Hall: there are aprox 40mm of threads in the plywood. I have done some small testing, and they seem to hold up the force for now. the problem I have encountered during testing is the rbber glued to the cams slipping of the cams. I am in the prosessing of trying different glue to stick the rubber to the wood. Epoxy, contact sement, ca glue and so on. i will post the result. I hadn`t tought of putting a rupper piece on the pad also, only put it on the clamps for friction
