Speed controller for RBI Hawk 220-2

[Nestcraft]

Hello all,
I just picked up an older RBI Hawk 220-2... it does not have a variable speed unit on it. Can I use a basic "router" type speed controller on this? I believe these have a DC motor so do I need a special type of controller?

This does have two speeds via the pulley under the machine but I am hoping to have a dial on top!

Thanks! I am new to it all.

I also have an older Hawk with the belt set-up, but mine is a 3 speed. Nope, do not use any kind of speed controller on it. You will damage the motor. Hawk does sell a new variable speed motor for it, but it's over $300. Eventually I am going to check with Grainger or places that carry electrical motors to price anything else compatable.
