re: Problem with Bessey Uniklamps slipping after a good cleaning!

After reading about all the problems that folks were having with these clamps on the link Klaus sent you Ellen it looks to me like they are very well designed useful clamps, but that there are some fatal flaw(s) in either the materials or perhaps the design. Seeing that you like them a lot it might help to think of them as a consumable rather than a long term tool.
