Guys, pls forgive the OT topic, but I need to get a 3/4" Jacobs chuck out of an old Skil Model 121 Special Duty drill (this thing is old, and large, and turns at 250 rpm, but looks like it could turn a 1" bit without a second thought), and can't figure out how to get the chuck out of the drill shaft.
I'm pretty sure its a threaded mounting, versus a tapered arbor, but I can't be sure. And I don't have a drawing or parts list for this old drill. I know how to get the chuck apart once I get it off the drill, but how do I get it broke loose?
Any help would be appreciated.... r/ Steve
