I said that tightening then up real good worked a while back. But i take that back. Even tightened as tight as i could get them WITH locktight they eventually started turning. I agree this is pathetic that a manufacturer would even sell such nonsense. Otherwise i love them tho, so the dremel is coming out as soon as i get a chance. I wouldn't mind it so much if they were cheaper, but $100 is a pretty hefty sum for pegs with a design flaw let alone if they were w/o problems.
