I have made several comments about the likes and dislikes of my CabinetMaster, Jet, and Bessey Revo clamps.
I remain sold on the CabinetMasters and thank goodness they will be in production again one day.
On my current small project I was trying to get my 12" Bessey Revo to slide all the way open but is simply would not slide past a certain point on the bar. No glue on the bar that I could see and that was frustrating with me being in the middle of a glue up. Out of desperation a whack with a hammer persuaded the clamp to open fully. Seems to be fine now but what a PIA.
Today while removing clamps from a small glue up I could not turn the handle much more than 1/8 of a turn on a Jet parallel clamp. That was enough to remove the clamp but the screw has seized midway between fully loose and fully tight. I'm eagerly waiting for a response from Jet, these like CabinetMasters have a life time warranty.
