I recently traded a jeep hardtop for this Rockwell 25-OX6 lathe. I am a machinist student and this seemed like a good deal. It has a 4 jaw chuck. Besides being dirty, this lathe works amazing . However I would like a 3 jaw chuck. Normally I would ask my instructor this question, but we are on break. This lathe has a taper spindle, the back of the chuck says Buck L102, is this the size adapter I need to put a 3 jaw chuck on this lathe?http://i1068.photobucket.com/albums/u442/oneIwilly/null_zps51df169f.jpg
