These are pictures of my transplant of a Surplus Center "2 HP Treadmill Motor"
to the mill drive of my asian 3in1 M/P machine (HF SKU 5981). The adaption is
straitforward, using the original motor mounting plate, re-drilled to accept the 
motor's front frame configuration. Two bushings are used to space the installed height
of the shaft properly. The original drive pulley is used. It is bored out to .750" and
a steel bushing made to fit the motor's .625" shaft. It is secured with a press fit
and set screw. 
The speed control is mounted to the mill column in an aluminum box, with the power to
the circuit board tapped from the main switch. The mill head can be operated 
independently from the lathe motor.
The original 4 groove belt drive is retained, and since the motor is variable speed,
this gives 4 torque ranges with spindle speeds of 60 to 4,300 rpm. At the lowest rpm,
I can't stop the spindle with my hand. The torque only goes up from there...

I used the 375 watt original mill motor to re-motor my HF 4x36" belt sander
HF SKU 36402). I drilled out the spotwelds holding the motor mount to the sander motor,
and welded the mount in place on the mill motor. I bought a slightly larger drive pulley
at Eagle, as I wanted a higher belt speed, and bored it out to fit the motors 18mm shaft.
The machine is now much more powerful, and with an 80 grit belt, can sand an aluminum 
block 4" square without stalling.
