I have a couple of seldom-used power tools that are palletized. My
system is to mount the tool on a steel plate and weld a piece of angle
to the bottom of the plate. To use the tool, the vertical leg of the
angle is held in the bench vise. It helps that I have my bench vise
mounted to the side of the bench, so that its top is even with the bench
top.

Oh, wait ... a more careful reading of your post reveals that your bench
vise itself is palletized. Pallet on pallet is probably not a good idea.
