Changing the chuck

There are 3 chucks that we have: a 3-jaw, 4-jaw, and 6-jaw. There are internal and external jaws available for the 3-jaw and 4-jaw.

To change the chuck, you will need 2 things:

• A scrap board to sit across the ways underneath the chuck
• A 3ft or so 2x4 or similar piece of lumber

Follow these instructions to remove the chuck and thread the new one on:

1. Lay the scrap board across the ways. This will prevent the chuck from falling once unthreaded and crashing against the ways, as well as give it a landing pad so you don't have to hold the weight for very long
2. Open the jaws enough to grip the 2x4, and lock them down on it. For a 3 jaw, this will be awkward.
3. Lock the back gears and lock the spindle to the pulleys, freezing the movement of the spindle.
4. Attempt to loosen the chuck by applying force to the 2x4. Use swift and repeated movements to try to "walk" the threads loose.
5. Once the chuck is loose, unthread it slowly until it is about off the threads, then prepare to gently lower it onto the scrap board
6. Once chuck is completely off, clean and oil the threads on the spindle and inside the chuck. This will keep the surfaces clean and rust-free, which will help the chucks remove easily.
7. Store the unused chuck under the lathe, covering it with a rag or plastic to keep it clean and prevent chips from getting in it.
8. Take your new chuck and inspect the threads. Clean them with a rag and oil them.
9. Thread the new chuck on. When it is close to being threaded all the way, take the chuck and spin it hard so when it gets to the end it locks it in.
10. All done!

Note: Do not use excessive force right away when removing the chuck. This method of removal has potential to damage the gearing in the lathe, so if there is a lot of trouble get some help before breaking the machine.

General Tips and Safety

• Do not reach over the headstock when turning on the lathe
• Make sure work is secured before turning on the lathe
• Ensure work and headstock will not collide with any part of the machine. Spin the headstock with the power off by hand to check this.
• Use sharp tools! Dull tools
