You can buy weighted bases that are specifically made for the Panavise 201 Jr; but I had the materials lying around and a lot of times making stuff is funner than buying it.

I used a 2.5lb plate weight (or dumbbell weight) for the weighted base. The only modification needed was the drilling of three holes for mounting the Panavise.
