Most of what I turn is bar stock. Either short peices or bars cut to

soft jaws and solve my problem, but.... do most of you use soft
jaws in your lathes?

Randy, For bar work I use a collet chuck which generally eliminates clearance
problems like you've described.

When I run cut pieces I tend to use pie jaws rather than a conventional looking
jaw. My cut blank work generally has a thru hole and I find that the
conventional jaws will give me a 3 lobed bore no matter how low the chuck
pressure is.

Steve,
I run a 5C collet for under 1" work, no tool interference problems
with this setup. My Hyundai has a 2.5" bar capacity thru the draw
tube, so for 2.5" stuff chuck jaws sticking out past the chuck start
to be a poblem.

I have never used a set of pie jaws, might be something I will need if
I get to thin walled stuff. There is no finesse on tighting the jaws
like on a manual lathe.

Randy, If you don't already know about US Shop Tools for lathe jaws here is a link:

http://www.usshoptools.com/

They offer hard, soft, and pie jaws in lots of sizes.

This guy on ebay makes a nicer soft jaw than US Shop Tools, especially his pie jaws:

I also like his 6" Kurt soft jaws. If you don't see what you need give him a
call and he more than likely makes it. Super nice guy, super quality.

Best,
Steve


Bought from USshoptolls already. I'll check the other guy, thanks.
