Wonder what speed ranges are obtained with that unusual/reversed pulley arrangement?
Appears to be an 'early'(0-8) version.
Here is a quote from the 10E preliminary manual that Everett is restoring.
"SHOPSMITH is equipped with a three-step cone pulley on the headstock, and a mating pulley for the motor. They will provide the three basic speeds required for nearly all operations. If an intermediate speed is desired, the motor can be moved on the motor bracket to align the pulleys for other ratios. For this condition, it will be necessary also to adjust the distance between pulley centers if the same belt is to be used."
I don't think that made it into the final 10E manual. It is not in the speed changer manual but there is no reason this would not work with the speed changer both with the motor pulley in normal and reverse position and by moving the motor on the mounting bracket. Most of the ranges would overlap but you should be able to get higher or lower than the standard configuration.
Maybe I should buy a digital tach and play.
