i made a coupling for the globe motors the other day for our winch. i started out with a 3" long peice of 5/8" steel shaft. then i drilled a 1/4" center hole into the shaft for the small round peice that comes out of the globe end. i drilled it on a lathe. then i moved onto our mill. its a manual bridgeport mill. i mounted the peice in the rotary chuck and centered the peice to the chuck using a 1/4" drill bit. i just lined it up so that the 1/4" bit in the chuck went smoothly into the center hole in the peice. then i put a 3/16 end mill in and milled away. i dont remeber how far i went in each direction, sorry. When i was done it fit perfectly. i hope this helps.
