scroll chuck lubrication

i like Bostik Dri Cote. spray it on and it dries to a slippery surface that lubes well but is not oily and wont attract dust.

I use lithium grease once every few years when I disassemble the chuck because it's getting stiff to move.

Hi Ken

I don't know about the Vicmark or any of the other makes, but my Oneway chuck has very little need for lubrication, the base jaws and the scroll plate has a manganese phosphate plating and is case hardened and there is a nickel surface on the chuck's body, makes for a very rust resistant surface that is also hard wearing and smooth, so unless you get a lot of sap or such thing in there, all you need to do is maybe blow out the dust. Since it has a open back, no shavings will get trapped and stay in, this is my experience with my chuck, and I have never had to take my chuck apart in the 5 years I own my Oneway Stronghold chuck, if it ever will need to be cleaned I will use a dry graphite lube, I would not use any lubricant that would have any stickiness, so as to keep sanding and other grit from sticking to it, this is best my opinion.

Have fun and take care Leo Van Der Loo

I'd certainly choose a mineral over an organic if using oil. They're famous for half-curing in isolation, and will gum the works. The amount in the aerosol is probably pretty small, though.

After a blast from the compressor, a wipe with WD40, my all-purpose iron cleaner is what I do.

When I opened one of the old ones a couple years back to remove a curl that had become lodged, I used a Teflon spray inside for lubrication.

I do a lot of staining and finishing on the lathe, so the chuck does pick up a little gunk here and there.. I use a toothbrush to clean the jaws, etc... did't take it apart, just fully opened that jaws.. A plastic pick got the stain/dust combo out of the jaw ridges.. then blew it off with air and brushed the exposed sliding surfaces with another toothbrush with a little mineral oil on it.. I figure that I sand with Mineral oil, so a little on the chuck wouldn't hurt..

Maufactures use light machine oil in their chucks.

How do I know this?

I have just bought a Precision Chuck from Axminster and thought I would just give it a quick spin. I wiped the oil film off the outside and set it running. The oil hiding inside did a quick exit putting a black speckled pattern diametrically across a wet sycamore bowl I had just finished and put on the bench to dry.

Can I pass this off as 'art'?

The bowl also comes with a matching shirt.

On the upside, it could have been coated in Cosmoline...

usually a matching floor mat, too.. DAMHIK..

Thanks everyone for the good answers, The graphite lube or the Bostik spray seems to be the way to go.
