|Piston Stop Block
I built an adjustable fence for my drill press and it was a great addition. Then
to make it even more versatile, I added this "piston" stop block.
As you can see in the
drawings below, the body of the stop block is made from two pieces of wood shaped
to fit over the fence and then screwed together. The "piston", used to tighten
the stop block down on the fence, is a short piece of 3/4"-dia. dowel. The dowel
fits into a hole that's pre-drilled into the inside face of the stop block. And
then a threaded insert is installed on the outside face.
