Default Check your wiring.

I was getting ready to use my drill press today and I found where the outer sheath of the wire going into the motor was worn threw. None of the wires inside were harmed so I taped it up. It was about 6" from the motor. I wouldn't be surprised if it wasn't like that when I bought it.

Be careful and enjoy your woodworking.

Measure once cut twice and it's still to short.

A good reminder, Don. And I'll second that because of what I found in mine 3 or 4 years ago. For no reason other than just doing a little drill press maintenance and clean up I pulled the cover off the junction box on the motor. What I found truly surprised me - there were bare wires! I also found bare wires on the switch.

This is what it looked like when I found it so I replaced the wiring and power cord that day -

That rubbery insulation flexes better but it degrades fairly quickly too.

Someone I consider a master woodworker once told me that a master woodworker is not someone who never makes mistakes. He is someone who is able to cover them up so that no one can tell.

David, that’s some scary right there . Im certainly glad you did some routine maintenance and found it before it caused a possible accident.

Don that’s a good reminder for everyone, thanks

With a small shop, your're always moving tools around, and fraying wiring is almost a certainty over time. Thanks for the reminder.

The more I do, the less I accomplish.

Not only moving tools around, but rodents will sometimes chew on the wires. I don't have rodents in my shop, but one cold winter I let my daughter keep her cat inside the shop for a few nights. Guess who chewed up the wires to my shop vac. Unfortunately the cat survived. As you might gather, I dislike cats.
Thanks for the reminder Don.

I like cats! They taste like chicken. God invented cats so dogs would have something to chew on.

I caught a mouse in my garage. Little vermin chewed a tiny corner off of a grass seed bag. I thought it was just scratched and taped it up. Next day it was leaking again! Doesn't leak any more.

Good to know!

Anyway, as long as grounding is well done, there is absolutly no risk.

The fuse will blow or the differential switch will break circuit.
Here the differential current norm is:
30 mA for any plugged moving tools with ground or not.
300mA for fixed, grounded tools like a drill-press, planer etc.

Switch died on my new HF drill press, within a week after buying it. Got a new switch at Lowes, for around $5, no problems since. That was probably 20 years ago.
