Hi Don,
I found the wing nuts on the thin Chinese screws strip the thread easily when you tighten up the clamps, so I used a thicker diameter screw and wing nut.
I also suggest you purchase these Japanese brass clamps. They are great for holding planks together.

Great idea.! I am always looking for new clamping ideas. But, those are spendy.!! I wonder if there is a local to U.S. supplier.?? Have to do some research.!!
