I see a typo in my orignal post. 30 tooth was supposed to be 38 tooth. My good press is a 16 speed Ironshith with a 4 grove pully on vertical shaft motor, and a jackshaft with a 5 grove the same as the drill post and as near as I can tell the speeds are 720 rpm up to 3250 rpm. What I am trying to work on is what some would call a post drill that could be mounted on a wall and turned with a hand crank on a horsiontal shaft. That horsiontal shaft has a 12 " pully-flywheel on one side for a horsintal shaft motor with the 22 tooth sprocket on the same shaft and that 22 tooth sprocket turns a 45 tooth sprocket that in turn turns a 38 tooth sprocket set to make a 90 degre change in direction from horisantal to vertical that is on the shaft the chuck is mounted on. The good drill press is what they call a 16MM and is a floor mount unit. Just runs way to fast for a 3/4" bit that I need to use in making hitch plates for this machinery I work on. The motor will just be an old flee market motor. The complete unit will probably not see much over a hundred holes a year if that much.

RPM x diameter of one + RPM x diameter of the other. Same as tooth count on sprockets.
