Small Motors

Hello All,
I need some help on some Vexta17 PK244-01AA DC.1.2Amp 3.30Ohm 2Phase
1.8/step Motors. I have 6 and want to use some of these to regulate
the variable switch on a VSR 2.0 HP router,and mill motors. All the
motors have Variable speed controls, and have used a tunner knob from
an old radio tunner to run the pulley, to the motor,and pulley, and
the cable, for the link to the motor. Hope you can undrestand this.
Now I want to find, build, (buy, not such a good idea), and driver
for this ,and a power supply. I have some regulated PS. 5V and 12
volt. and run 5amps. What would be the most cost effected method to
get these motors to work. As I am not too familar,with Electronics,but
have soldered and done some simple boards, but nothing to where I
could size a driver, and such. Can Anyone give me a direction as to
what I could use to get these motors to work. I looked on KitsRUs, and
don't know any more now, then I did looking for something. Appreciate
any Help. I would like to build, if I can. Thanks For Reading,
Thanks, Hank S.
