Re: Pedestal base
The difference between a pedestal and C clamp vise is not just the base. The stem is shorter on the pedestal.
Measure the distance from the table top to the top of the vise that is comfortable to you and make sure that when you get a pedestal, you cut the stem down so the vise is at the same height including the pedestal.
