Re: As if I need another expensive hobby...
I bought the Danvise last winter and I am quite pleased with it. Mine came with a short video on how to mount a hook. The metal tips are apparently susceptible to being "sprung" if you clamp too hard on a hook, but all that can be avoided by adjusting the opening to be just snug with the cam half closed - the video shows how. There is also book by Al Beatty on the market comparing various rotary vises and showing how to make good use of one.
