Here's the simple vise jig, Sean, made from two pieces plywood, notched to fit down over the vise mechanism. Because it's relatively "soft" it does not mar the stick unless I crank down with too much force.
I use that lower "T" shaped unit to give vertical support/strength to the stick, such as when I'm drilling the hole in the top for the dowel screw . . . or when I'm sanding the top with that shoe-shine motion.
When not in use, I kick the lower unit back under the work bench.
Disregard, please, the poinsettia. It's headed for the curb next Tuesday evening.
