What is an MC-60 controller?
George
Hi George;
It's a motor power supply and variable speed unit for medium sized DC motors.
If you want variable speed, you need something like a controller. I don't suppose it has to be as complicated as an MC-60. That is just the type I know will work with the motor in the link from my previous post.
Darren on MadModder forum has a nice article on how to make a power supply. It looks simple enough that even I could build it, which is saying something. Have a look here;

You might want to write him with specific questions about it, and what kind of motor it would run.
Using a DC motor and some kind of power supply is one way to get what you want. They seem to make quite a bit of power and torque relative to their size. Small AC motors, like those in the Dremel may work too, but from my experience using one, they are quite low in the torque department. Many of them have the advantage of being able to run from one of those small router variable speed units, though.
The motor in the link you have for your project looks like what I see on ebay quite often. It's hard to tell it's size, but I'll bet it is fairly small. Maybe 1 3/4" dia by 4" length, or in that range. Unless the O-ring shown in the picture is a great big thing, that motor wouldn't seem to be very large. BTW, the one shown on the JEH site is a DC motor.
