At least on my 14 1/2, there is still a considerable amount of inertia in the motor, belt cones and geartrain.
Simple steps.
Bake sure NOT in back gear.
Gear train off.
Get a chunk if 2 X 4 2 ft long.
The biggest hammer you can find and a helper.
Chuck needs to have something in it and snug and magic will happen.
Observe the flat in the hole for chuck wrench as it needs to be parallel to ways
Now rotate chuck to where the chuck wrench is straight out in front.
Place the chuck wrench into the hole.
Have the helper hold the 2 X 4 across the chuck key snug to the chuck.
Smack it with the hammer GENTLY.
small hammer you need speed nut large hammer has more energy so gentle smack usually will do it.
Rotate and repeat with 1 or 2 smacks on each hole and it should come loose.
Last time you installed it you may not have seated it and it seated while using.
We usually give the last 1/4 turn a rapid spin and that seats it and removal not to bad.
We used this method often in the shop, and it often works. You aren't putting the machine in back gears, the spindle is free turning so there is no chance of damaging anything.NOOOO, that is sure to break a gear.
Having the jaws closed on something makes the chuck a solid piece.Nooooo. The hex he had in the jaws was better than this recommendation. The hex in the jaws is a natural action for the chuck, banging on it like you are suggesting is a good way to break the casting, or the pinion gear which has a journal that rides in the casting. Either could break.
You assume he does not have a gear head.We used this method often in the shop, and it often works. You aren't putting the machine in back gears, the spindle is free turning so there is no chance of damaging anything.
No assumptions. My original comment was on freeing the chuck with out putting in back gears, and without pounding on anything. Either with the chuck wrench, or a pc of stock between jaws, and by hand a quick clockwise motion and quick reversal in direction, the chuck would often come offYou assume he does not have a gear head.
