For reason beyond my thinking, I mounted the motor to operate a toothed belt to drive the head. I could just as easily mounted it direct. The PM25 head crank is on the left at the top of the column. I fabricated a mount on the bearing retainer there mounted the motor on the back of the mount. I put too toothed pulleys on the other side of the mount, one on the motor one on the crank shaft. The hardest part was making an output shaft from the motor. as it comes it has a stub about 1.4" long, square with a rounded half. Originally a flat piece of steel was pressed on to this stub. Using the mill I carved a hole in the end of a shaft that went threw two bearings with the toothed pulley between them.
I wish I had more RPMs, seems to take forever running the head up and down, between using a drill chuck or a milling cutter. Fifteen seconds per inch for 2 1/2 inches isn't long, but If I had a 4 Inch quill I wouldn't have to do it.
