This has to be the cheapest and easiest way to make a tap holder. These are made using threaded rod connector nuts and some bolts. Nice thing is they are already drilled and tapped so all you do is drill the hole(s) for the tap and you're done.
To fit all my taps, I made 3 different sizes. Each one has 2 different sized holes so you pick the one that fits best. These fit everything from my 4-40 up to 1/2 inch taps.
You could opt to make handles instead of using the bolts.
I would recommend lock-nuts on the handles. Hand pressure may loosen the bolts while threading. If the hardened tap falls out onto a concrete floor it will break.
That's why I prefer the style...

where the tap-holding screws are not part of the handles.

Looks great. But how does a square tap work in a round hole?
Bob
Very nice but I think I would go in the direction Marv showed but I would turn the long nut on the outer parts to receive a piece of tubing instead of bolts. The length would be what ever to get the torque required to cut the threads. There is so much could be done with the idea and make a very nice tool.
Thanks for sharing

Just screw the bolts in and they grip on the flatsQuote:

I'd be tempted to drill the six different sized holes into a single threaded rod connector. Weakening of the connector likely inconsequential. One tool instead of three.
