HOW TO FIX SLIPPING PIPE CRAMPS
I don’t need to elaborate the feelings one gets when doing a large glue up when all the cramp wants to do is slide down the pipe.
This mod/repair was done many many years ago. I disassembled the sliding jaw and and cut off the “teeth” stamped into the clamping part. I had in amongst my stuff a broken Brobo Coldsaw Blade. I figured that if I brazed the portion of blade to replace the punched teeth the harder steel would bite into the pipe better.I first drew an out line so that the piece of blade when brazed would still fit into the clamping jaw housing.
I am no expert with a brazing torch but the flux coated rods made the job easy and quick. When cooled I was able to grind off some excess braze to make the jaw fit back into position.
Did it work??? Yep. Now because the Brobo blade is quite hard, when in use and put a lot of force on the threaded screw, The teeth can dig into the soft pipe. All I di periodically is run a file over the lumps and the cramp is ready to do its job on the next glue up
