Default Now that the good cheap motors are gone, what do we use to motorize a Barley Crusher?

A Drill! I do it by hand at the moment but I am building a ghetto setup to hold it in place and a vice like device to adjust the trigger and speed...

An Extra Pulley and:

Washer Motor, Tablesaw Motor..there are a whole lot of cheap motors out there. I bet you can find a washer motor for free driving down the road in the right place. Then you just need to calculate the RPM and figure out the pulley to reduce it to 185-200

Well, I don't know as the good cheap motors are gone. I've seen lots of motors come and go on eBay and elsewhere. There are people on here who have recommended what seems to be a very reasonably priced Harbor Freight AC drill that works. If I were looking to put a fixed motor on my mill (right now, I use an old Craftsman 1/2" AC drill), I think I'd look first at a junked wiper motor off a semi. Their rpms may spec out a bit slow, but they have plenty of torque, and with a permanent mount, who cares if it takes a bit longer? The biggest problem with those units is coming up with a 12VDC power supply.

With a few hand tools and a couple of common hardware items a hand drill could be mounted permanently like a gearmotor. I'd probably consider cutting the handle portion off and wiring the motor to a light switch.

I would think a bit slow with torque wouldn't be as bad as way too fast. drills tend to operate way too fast, so it's good to tame them down a bit with a pulley.

Guess what. I have one of these that is new in the box. It was my father-in-law's. He left it with my wife when he passed away. He would be happy for me to use it. He was an engineer.

I also have a speed control for a router that I could use to control the speed.

It will work either way likely! However, it would work better if you added one pulley to adjust the speed, that way you get added torque for the slower RPM
