I'm donating 6 self made wooded hand screw clamps for a free prize draw among forum stand helpers at the T & WWW Show in Melbourne.
I made these clamps many years ago and worked well but my interest in woodworking has changed and now I no longer need that many clamps. They still work well but may need a bit of lubrication (a quick spray with WD 40) on the threads.
