We have a task at work that involves putting 0-80 holes thru 1/8 polycarbonate. (Lexan is a brand name) Lots of holes.12/part times 100 parts.
I have a sweet little tapper that goes to 0-80, and it does its job of limiting the torque, but it is difficult to control, even with a smaller drill press, due to the leverage of the handle, and the mass of the quill.
I wonder if anyone in here knows of a sensitive feed unit that might work well with a small tapper. That way, you could feed the tapper up and down with just your fingertips.
I'd prefer to do this on the cheap. I considered that I could rig up a teeny little CNC rigid tapper, but this is a bit more time and money than I care to invest.
