I finally upgraded to big boy clamps. I won four jorgenson cabinet clamps on ebay ( 2 three foot and 2 four foot) for $80 (locale pickup only). I used them to clamp up a cutting board and I now know what I was missing all these years. They kept the wood perfectly inline. They will save me a lot of clamp up time.
