Question about wiring for drill press

[MidnightZ21]

I am working on fixing up a drill press I inherited from my father in law. I showed the press in my other post about cleaning out his garage. The wiring he had on it wasn't up to par. He had romex and a light switch. I am putting on some stranded wire and looking to mount a switch somewhere.

My question is should I ground the motor? He didn't have a ground anywhere. There isn't a lug on the motor, but I could probably ground it to a case screw if that would make it safer. Here are pics of the motor plate and the terminals. Thanks for the input.

yes, the motor should have a ground as well as the body of the press, and the switch box ,if you install one , should all be grounded

+1, certainly ground the motor. You can drill and tap for a screw. And a case screw would be way better than nothing. The motor should be a fun project in its own right.

Mount the switch somewhere easily accessible when using the press, ideally up front. I really like the paddle switches you find on modern tools.

Those are nice switches I have one here.
You can even get them with a safety on them I forget the technical name for it, but if you lose power and restore power it will stay off until you reset it.

It's called a Magnetic switch. Like this one:

One comment on switches - the random name stuff of Amazon i have found be hit and miss. While cheap you get what you pay for. I bought a bunch of switches for some machines at work and 50% had high or infinite switch resistance. I find new old stock on Ebay a much better value.

It's reasonable too.

I just want to note that the magnetic switch is not a simple drop-in replacement on some older machines. I installed one on my Wilton USA drill press in the factory location located in the front of the main casting. There were only 2 wires as the original switch only controlled the hot leg. The magnetic switch requires that you control both legs (just like with 240vac) or it won't work. I had to rewire the DP with extra cables to handle the magnetic switch.
