Jammed Chuck?

By Terry Scott and Dick Veitch

Terry receives many a call or email asking “How do I get my chuck off my lathe  spindle?”

Firstly, he says “Have you checked that the grub screw has been taken out of the insert/Adapter?“  Many woodturners have damaged their spindle thread trying to force the screwed-on chuck insert off the headstock spindle.

Next question “Do you use a chuck spanner?”

If you don’t firmly tighten the chuck on the spindle, the chuck can snap up that last fraction of a millimetre when you start the lathe or have a little dig-in.  To avoid this firm up the chuck using a chuck spanner.  Have the spindle lock engaged and give the spanner a firm push or thump with the heel of your hand.  Reverse this process to remove the chuck later.

If your chuck is bound firmly to the spindle you may stretch the Teknatool chuck spanner or round over the nut edges trying to take it off.  Some chuck insert nuts are now made with rounded corners and a slightly stretched spanner will no longer work.  A thicker, stronger, 38mmx 4.5mm thick spanner is needed.  An open-ended spanner from the local store works but may need to be ground thinner to fit between the chuck and headstock.  The Timberly chuck spanner has been designed for this purpose.  You can make it even better by adding a wooden handle.

Some users may advise you to fit a washer between the chuck and headstock.  If you really feel a need to do this, take care.  The washer material needs to have perfectly even thickness or your chuck, and the attached wood, will be thrown out of line.  Materials like mechanic’s gasket paper or formica sheet can be used but many other materials have uneven thickness.

If your chuck is just 0.1 of a millimetre out of alignment at the spindle face then the edge of a 200mm deep vase will be 2.0mm out of line and that will be a problem when you turn the wood around to cut the inside.

When you get a new chuck and a new insert take care to clean the thread, and the flat area at the end of it, deep inside the chuck.  Wipe the insert clean as well.  Tighten the insert very firmly into the chuck.  Put a grubscrew(supplied with new chucks ) into the side of the chuck to lock the insert in place.  You may put a bit of Loctite on that grubscrew to ensure it stays in place.

Each chuck you have needs its own insert. Leaving an insert on the spindle, and not having one in each chuck, is a no no as the thread in the back of the chuck is not designed for repeated on and offs. When the thread between the chuck and adaptor wears, the insert does not seat properly in the chuck causing the chuck to run out.

Another common cause of bad alignment in a chuck is the fitting of the jaws.  When you get new chuck jaws, or refit old ones, don’t just cinch up the screws holding each jaw.  Instead, tighten those screws, then ease them off by half a turn.  Now, close the chuck fairly firmly to ensure that the jaws are a complete circle and then tighten the jaw screws firmly.

 It is recommend to replace the jaw skews every so often if you are repeatedly changing jaws as the allen key hole can become striped .A small amount of crc applied before removal can help ,Clean out any resin or dust build up  with a pick or air We also recommend cutting of the ball on the t bar Allen key For the initial placement of your chuck on the lathe it is better to hold it in one hand and rotate the handwheel or spindle rather than initially locking your spindle, rotating the chuck, and possibly dropping it.Don’t remove the chuck by placing your knock out bar, chuck key, or other lever, between the jaws.  This can damage to the jaws and often the jaw slides as well. The grub screw fitted in the chuck insert/adaptor, referred to in the first paragraph of this article, is intended to secure the chuck to the spindle for reverse turning.  Very few people rotate the lathe in reverse for turning – maybe a few left-handers and maybe some hollowers.  More may rotate the lathe in reverse for sanding and then we find tightening the chuck with a chuck spanner is perfectly adequate.
