I bought an old electric drill from Ebay, a '1/4" High Power, Model 77"
, made by Portable Electric Tools Inc., Chicago 20 Illinois.
Its a 2 wire set up, and when I tried to clean the rusty chuck by running it against a small wire brush mounted in my table vise, it shocked me.
So now, with gloves on, it sparks at the point of contact each time I run it against any grounded metal.
I can run it fine if its touching something ungrounded or non metalic.
Inside, I found a thread or two of wire near the switch, touching the housing, and I cleaned that up, but no success.
I re-wired the plug, but no success.
I blew it all out around the brushes as best I could, without complete dissassembly.
Can I put a 3 wire set up on it, would that work?
Or does it sound like a more serious problem?
I'm guessing this is a problem with old tools?
Any advice would be appreciated.
Thanks,
Gary
