Take 2, 2x4's and cut two short blocks off of each. Attach one black on
one end, the other on the opposite end AND side. Those are now your bar
clamps. Us a short clamp to pull them together.

Yabbut, it looks a lot prettier to have several full length clamps
ready for use on a moment's notice.

Besides, 2x4's are so expensive these days.
