The past two years have been challenging shop-wise while undergoing two cataract surgeries. Recently, a retinal detachment in my trusty right eye promises to lead to the temporary (if one can call several months to two years temporary) healing and hopeful recovery of my sight.
Problem: I have usually tapped by sight.
Idea: Make a tapping block and machine!
New problem: Doing layout to build a machine is difficult with a gas bubble in my eye! So, one of my old hand drill stands became the basis of my project.
I drilled and tapped the end of the shaft so a surplus chuck could be installed to hold the tapping wrench. I reversed the retraction spring so the pressure pushes down on the tap. Voila: a small tapping machine!
