A tapping arm for the shed

Related to showing mistakes in fabrication, there is variation in goals.

I view hobby machining as permission to be as crazy and worthless as I want. Today I might want to make a paperweight that is within 1/2 thou of an arbitrary value. Another day I just want to slap together a few bits to try out an idea.

I have many many bad idea. A few I even build. A tiny number of them are almost useful and once in a while I produce a good idea. For me, this is fun.
