Removing a Stuck Wood Lathe Chuck Removing a Stuck Wood Lathe Chuck

What You'll Need
Chuck Key or pry bar
Strap wrench
Leather belt
Heat Gun
Oil

If you do a lot of wood working, then you may find that from time to time your wood lathe chuck sticks in the lathe, and you are unable to remove it just by jiggling the machine up and down. In these circumstances, you need to remove the chuck completely before it breaks and harms the rest of your tool, but you also want to stop the machine from working while you do so, in order to keep all of your fingers. There are a number of ways in which you can stop the spindle from turning while you get rid of the chuck, so just follow some simple guidelines to taking out your chuck while keeping all of your fingers.

Step 1 - Stop the Lathe

In order to remove the wood lathe chuck you need to stop the parts of the larger machine from working. Do this by using a strap wrench, a leather belt, or other method of immobilizing your spindle. If your wood lathe is connected to electricity, then you need to turn the lathe off at the wall as well, to prevent accidents. If you don't have a specialist device for immobilizing the spindle, then take an old leather belt, and cut the holes in it so that the spindle teeth stick into the belt, and then tie the leather to prevent the teeth from moving. This should keep your spindle immobile long enough to remove the chuck.

Step 2 - Loosen the Chuck

If your chuck is attached to a plate, then you will need to loosen it before you can remove it from the lathe. You may need to unscrew some of the mounting bolts to get at the chuck. Use a heat gun, or glue gun without the glue stick, and gently warm up the backing plate until the glue on it starts to sizzle. You should then spray some air onto the backing plate, and this should loosen the chuck enough to get it moving.

Step 3 - Extract the Chuck

You should now have the chuck loosened enough to extract it. Some use the back gears to move the chuck towards the spindle, but this can cause the wheel to loose teeth, so you are better off using a pry bar to lift the wood lathe chuck up towards you. If you have one, use the chuck key, which is another kind of metal bar, to move the whole of the chuck out of the lathe. Once your chuck is free from the machine, pick it up,, and carry it away.

Step 4 - Repairing the Lathe

Now you have removed the chuck you have a broken lathe which will need to be repaired before you can do anything with it. Take your spindle, and release the teeth from the strap holding it down. Take either the repaired chuck or another, and place it into position on the back plate, and move the two together before you turn the lathe back on.
