This is the wood version of cast iron pipe clamps.
My cast iron versions I can put on any length of pipe and
clamp. The only issue is they are not super strong and they
don't have very large faces.
The pipe is strong and can be extended with connectors adding pipes.
Bar clamps are fixed.

Nice thing is you have the two clamping ends and the length of wood you
need and cut the sawtooth pattern only where you need them. Custom the
size of a house or a thimble.

Buying a strong board that will hold the holes when pulled or pushed
upon would be expensive.
I have some 18' 4x4's in Red Oak. They are only 2 years in drying and
the log was 30 some odd inches in diameter. I have a bunch of them.
Total was 74. But many are shorter.
One has to be able to pickup the wood, the wood has to have strength
from tear-out.
Dogs are great on thick hard benches. Fair in pine or fur.

would be a versatile clamp to have when something needs clamping and
is an odd size
i think i saw the same idea in a modern design that used a 2x4 with
the clamp fitting on each end of the 2x4 but do not remember where i
saw those

yeah their strength would be a problem
but i have never seen them before and it is always interesting to see
tool heritage and consider the refinements over time
with the other post mention of the bench dogs i am surprised that
solution was not used in the past because i think that is a much
stringer setup

a doug fir 2x4 would be very strong in that direction
and easy to repurpose
a good backup at least if you get into a gluing situation and realize
you need more clamps

No, it's not. A 2x4 will twist very easily. Since the force is only
on one side of the board, it will warp and/or twist.

There are better solutions (a good bench, for one).
