Building some cabinets, and not having the proper length clamps, got me thinking I needed some of those.
I was given 150 feet of 1” galvanized steel pipes at work, and figured this could be used.
Also got some 40mm oak countertop cut offs that was suitable.
Clamps are made like a bar clamp, but has the “friction stop” function of a pipeclamp (no rifles in the clamp bar) just the “binding” between the angeled sheet metal and the pipe.
The sheet metal pieces are not tempered, but seem to hold up really well. They can easily be removed for tempering or replacing if the clamp should start slipping
There is also a block at the bottom of the clamp to make thems stand up by themselves during glue-up
The wood is threaded directly for the threaded rod (no T-nut) and the handle is made from 24 mm broom stick cut offs, with a foam/rubber bicycle handle grip, the threads are suprisingly strong (test in the video)
The steel pipe should not be less than 1” I think. This is relatively “thick walled” pipe with 2mm thick walls
If you have accsess to a large thread cutter you could of course make extensions for these.
