Bessey’s Maxis VarioPivot clamping system extends the versatility of your bar clamps by attaching them to your bench, somewhat like the previously covered VersaClamp. It works best with Bessey’s K-Body Clamps, but they claim the system works with other bar or pipe clamps too.
The two C-clamp-like ends attach to your bench top and capture any length of bar clamp between them. The clamps fit into rotating holders which can lock the bar clamp at any angle between 0 to 270°. The holders rest in an L-shaped track, which allows you to position the bar clamp along the side of the bench or over the work surface.
The Maxis VarioPivot Clamping system comes with the two c-clamp ends and runs about $50. You’ll need to provide your own bar clamp.
