I occasionally design, etch and drill simple circuit boards. My drilling "skills" are pathetic. Often I had to twist connectors to make them fit into the holes.
Now I have an indexing system that solves the problem. The best part is that it uses just a perf board, some white Elmer's glue, and two pins stolen from a connector.
If you are interested, please see

Your comments are welcome. All of us are smarter than any one of us.
Thanks,
Rick
Awesome, it's a FMC pcb machine (Finger-Manually-Controlled) :-) Clever solution.
Does this make it digit-al control?Quote:

I used to use pre-perforated board as a guide to drill needed holes into metal drilling jigs which in turn were used to drill unetched PCB. I would then use the holes as a guide to draw the tracks prior to etching.

Two examples of the drilling jigs and the finished boards.
I had a tiny high speed drill (much smaller than a Dremel) and the whole operation was manual.

Pretty cool but I’m surprised you have not made a CNC machine by now.
I do have a CNC driven mill but can drill all the holes in a one-off board faster than it takes to boot up.Quote:

Now, if I was going to mill the board rather than chemically etch it, I would certainly use my CNC mill.

It is unclear if you were addressing your comment to Rick or me. Rick has already answered. My comment above referred to boards that I made in the early 1980's.Quote:
