in the process of teaching a special student here
that has very limited clamps for breadboards at home
i came up with this quick clamp idea
(this is a trial one so not mass produced or tooled to tight yet)

the idea is from the age old wedges and stops
to clamp things together

this one is adjustable by sliding the stops back and forth
and inserting the pin in the appropriate hole
and tightening with the wedges
(different width wedges can be used for fine tuning)

the real mccoy would be using a bolt or metal rod
and a set of different sized ones for different width
glue-ups can be made

tap the wedges to tighten

simple and easy to make and use

Hello Patron!

Good to see you!

In your clamps, I can see how the wedges would be used to do the final Tightening to the Clamp to make it “Clamp”... BUT, I wonder how you would be removing the wedges to undo the Clamp…

I’m sure you have a very ingenius way of doing it but, from the pictures I cannot see it.

COOL approach…

I can see careful wood selection, hardness, grain, etc. to make GOOD Strong clamps being needed.

Thank you!

edit: Wouldn’t all of those holes weaken the main Bar?

hey joe

the main thing is to have good joints to begin with
straight and tight together
the wedges just bring them together till the glue squeezes some
and holds them there till it dries
(wax or tape the rail and wedge parts first)

not meant to compete with muscle clamps of steel
just to tighten enough to do the job

to loosen the wedges
just tap lightly and wiggle loose
for those that need some help till they can win the lottery
and buy thousands of clamps

Interesting.I like it. Seems like a good way and better feel of the clamping pressure.

The Inclined Plane strikes again!
Nice use of it here Boss…
(Keep that wedge angle slim though,
or you won’t have to worry about how to open it!)

Nice idea David.

Joe, no reason why the wedges could not be tapped out from beneath. If necessary, just make the wedges a little fatter so that the thin end is big enough to hit.

Looks good David. When I designed the vices on my bench I just made the wedges so they “looked right” and they turned out to be ~8 degrees. I’ll bet you just made them by eye as well and I’ll also bet they are about 8 degrees.
...... sweet spot, yes?
Remember to chamfer the corners on the striking surfaces. (I know you knew that)

Good idea David. Thanks for sharing.

Wedges are wonderful.

I use ‘em to clamp the pieces together when I make one of those hexagon table tops out of four sided pieces of cedar.

I screw wood blocks to the workbench in the general shape needed, toss in 32 pieces of hexagon halves, slap ‘em around with the palm of my hand, tapping and shimming until I get things lined up and locked in place.

Apply the substrate, bull nose, & wal-la a table top.

I got another table ready. I haven’t taken pictures yet. Was planning on posting a picture sometime soon.

Bravo for home made wooden clamps. I always wondering do they have same strenght as metal clamps. Nice work anyway.
