I have a PM 3520b,and the head can slide all the way to the end for outboard turning.The floor stands made my PM are almost $400, forcing me to come up with a design out of wood or iron that i cobble myself.Any info, of successful designs and if your happy with how your tool rest operates in your floor stand.I'd like to make mine out of wood, hollow the center and pour lead shot or some such in the legs..Thanks rob
