Only once a month? My guy has made several postings for it and does it as much as possible!Put it on CL for $100 and bump the listing once a month, that's what someone here does
Seriously though, I'd try the dremel idea or maybe a rotozip...
It's called a hollow chisel mortiser. I don't think this would work for one, but maybe some sort of light press though.I have one of those with the original drill in it. The drill needs a new power cord to be safe to use. There is a woodworking tool (the name escapes me at the time) where a chisel is mounted in a similar device. It's used to clean up a slot that is rough cut in the wood. Basically the chisel is plunged into the wood, the wood is moved slightly and the chisel is plunged again until the slot is clean.
Now THAT is a cool idea!Find a hand drill to put in it. Find an old spoon that you can grind the width of the handle down. Put the spoon in the chuck and turn it into a garage cocktail mixer.

get a drill to fit and make a dedicated stirring machine.

If you don't have a mag drill or if you need to drill a straight hole in the center of a large sheet you can clamp it down and use it.
I had to drill a few holes in a large plate, 350 or 400 lbs, no way I was going to lift that onto my drill press not to mention it was about 20 inches from any edge so the press wouldn't have worked anyway, I put the Mil hole shooter in a similar rig and clapmed it over the spot, made a ver serviceable hole.
cut down a paint stirrer![]()
You guys are over thinking it, hit some garage sales this weekend and I bet you'll find one of these for $1 or so...

Valid point and equally useful, but when you are in the garage mixing up a Jack and Marvel Mystery what mixer will look better?

You never mentioned that concoction, in this case, I would use one of these.
