Has anyone got the four jaw chuck for the clarks cwlb6 woodturning lathe? I need some guidance on the best use for it. My work is always off centre even after adjusting the base to what I think is perfectly level. Also my work sometimes flies off the lathe even when I feel the job is tight enough.

Had one,never really got on with it - each jaw was tightened seperately,and even though there were concentric lines as a guide,wouldn't have liked to try and get anything to fit in the same place again..
As for things flying off,the jaws were parallel and fairly smooth - make sure the spigot you make doesn't quite "bottom out" in the chuck (so that it seats squarely) and perhaps try a very slight taper (only a couple of degrees max.) so that the end in the chuck is a gnats wider,making it harder to come out.
Ideally,get a decent scroll chuck.. 8)

A good independant 4jaw chuck will be more accurate than most scroll or self centering 3jaw chucks. I am happy with 0.0005" or less when seting work up on my engineering one.
For woodworking you should be able to set it to within 1/32" by eye against a reference point without resorting to dial test indicators. This is about as much as you could expect with a cheap chuck and wood.
If its flying out of the chuck you either don't have enough material in the chuck or there is too much sticking out with no tailstock support.

I had the same one and the same problems, it's really worth the extra few quid if you can afford a scroll chuck, my bowl work improved 10 fold once I was certain the bowl wouldn't scream past my ear! (it still does sometimes but it's much clearer who's to blame now)

Supanova 2 is the chuck for me, got it b4 it went chinese, so I'd probably look at the patriot now
That being said, I would have thought that any scrool chuck is better than the one your using?

Well Dave
I looked up your suggestion for the above chuck and decided to buy it. I've just had a full day in the garage(sorry workshop) turning some small plates and small items. ``the plates are made out of an old bar table and i'm more than impressed with the chuck. I returned my other chuck that I previously mentioned and exchanged it for a bench drill. I'll probably put some endeavours on the site soon. Thanks dave, a brilliant buy.
