Is it ok to use a paper washer to prevent chucks getting stuck?

[ome]

Hi guys,
I was thinking back when i was turning alot of wood, before i ever had a metal lathe, and i always made a paper washer, even out of thin cardboard, and the chuck always came off fairly easy.
I never oiled the spindle nose or the chucks threads.
What do you think?
thanks
Jon

-Just want to mention that the primary reason a chuck gets stuck is from doing interrupted cuts. If you're turning down a square shaft, each time that bit hits, it's tightening the chuck. Best way to prevent this is make sure the chuck is free of swarf and properly lubed before installing it. Also, when doing interrupted cuts, go lightly and every now and then, loosen the chuck to verify it's not getting hopelessly stuck.

As for paper shim... Maybe in some hobby conditions this is OK. I have never heard of this actually. In precision work, it would not fly.

I tried that a long time ago - and was no good. the paper "washer" would get chewed up, and add to that the fact you have lubrication and oil makes this idea less than productive. if you must - use another material for the washer that won't deteriorate and will have non-stick characteristics (UHMW/phenolic are 2 that come to mind)

Thanks Ray for that solid bit of advice.

I agree on all points! The only times I have gotten chucks stuck were interrupted cuts or when it was polishing or something that puts a lot of pressure on the part. Cutting does not put as much pressure as this.

I have heard George Wilson mention the use of paper a number of times for many different reasons, but usually to INCREASE friction.
