FILENAMES: Faceplat.txt (this file only) DESCRIPTION: Description of making a mounting faceplate for one of the surplus GE type treadmill motors. Posted by Alan Inness . Alan provided the following description: ========================================================================== This article describes the fitting of a Faceplate mounting to a GE type treadmill motor in order to convert a 12" Craftsman wood Bandsaw to variable speed metal cutting using the solid state controller. The first step is to turn a piece of 6"x6"x1/2" aluminum to a circular disc 5.75 dia. with a 2" dia. center hole. Next drill four #10 clearance holes at a radius of 2" from the center, 90 deg. apart. These will become the faceplate-to-motor mounting holes. Next Drill and tap #10-32 another four holes at a radius of 2.59" (5 3/16" dia) 90 deg apart and at 45 deg to the first set of holes. Screw in 1.25" Allen head screw into the tapped holes using loctite. These four studs will replicate the method of mounting used by the original motor. This completes the face plate. Remove the rubber motor mount cushion from the shaft end of the motor and discard. Remove the #10 rods securing the motor end caseings and replace with #10-24 threaded rod, 6.75" in length, allowing the rods to protude from the shaft-end cover by 1.125". Place the Alum. face plate over these two rods temporarily secure by four nuts (two each side of the plate). The other two clearance holes should now line up with the webs of the motor end plate, MARK ONLY by using the holes as guides to spot drill the endplate webs. Remove the New faceplate and the motor end just marked, and drill & tap #10-32, the previously marked holes. Reassemble the motor and bolt the new face plate to the end cover using #10 screws, and nuts placed over the new #10 rods. There is one last thing that was discovered on assembly was that the motor shaft is now .25" too long, Therefore There are four options that can be made to overcome this, i.e. 1/ Make the new faceplate from 3/4" material, 2/ Bore out the pulley 1/4" deeper. 3/ Move the face plate out from the endcover by 1/4" 4/ Trim 1/4" of the end of the shaft. I decided on option 4 and it worked out OK. The original #10 spacers were fitted over the Allen screws and the motor was secured by new #10 self-locking nuts. The minimum speed obtained whilst cutting aluminum stock without stalling was around 130ft/min.
