Hello everyone. First time posting but ive read abit. Ive bought an schaublin 13 -63 milling machine. It was pretty much in parts so ive been rebuilding it and now ive run in to a problem. The feed dont work. The feedbox seems fine but its not turning the shaft that goes up in the apron i guess is the name for it. Looking at this not verry high quality exploded image. Can anyone tell me what this part is? If you have i picture i would be verry happy if you could share it with me.
