I tried to remove the chuck (3 jaw) from my Unimat 3, but it wouldn't come loose. I finally used an allen wrench in the chuck, another in the hole in the spindle, and a plastic hammer. I came loose on the 4th blow. The allen wrench in the spindle now has a nice bend, but it was cheap one so I'm not upset. Before I put anything back together, I'd like to know if someone has a secret formula (or some widely known machinists trick) for keeping the chuck from getting stuck next time? There are no signs of any rust or corrosion nastiness, but not much in the way of oil or grease either.
Thanks for any and all help.
