Review on Robert Larson 560 3250 Miter Saw by Rick Everett

I did a lot of research when I was looking for a clamping system for picture frames. I kept coming back to Ulmia and decided to give it a try. They look good but just don't work with the woods I tested them on: maple, oak, pine, crimsonheart and cherry. The springs have nail-sharp ends which, when clamped with the lightest pressure and still managed to miter, punched various holes and notches in the wood. I even tried one on the lovely wooden box they came in and it crashed into the side. (Has the returns department noticed this?) I'm not sure what application would be used if gouging is an acceptable part of the clamp. Ulmia's design to me is "Yes!" What happens when you cut sharp, hardened steel into wood? I should have found that out before wasting time buying and returning.
