    Default How to hold small diameter stuff

    Dear all,

    I have the Herless lathe with a cheap Chinese chuck that you can't buy extra jaws for to hold thin stuff without tailstock support. The chuck squeezes down to about 40 ml diameter. Until I get a new more expensive chuck, does anyone know of how I can hold anything less than 40 ml without tailstock support. Has anyone made jaws that can be attached to hold thinner diameter work?

    There are numerous ways to hold small diameters.
    Hold between centres.
    Shape the end to fit in the morse taper.
    Use a Jacobs chuck at the drive end.
    Glue the small bit to a wooden face plate.
    Tenon the end and fit it into a tight drilled hole.
    Hold a big bit in the chuck and make it into a small diameter.

    PS. Did you get some more tools?

    I made some pin-jaws for the chaiwanese chuck that came with my MC-900.

    I persevered with 'em for all of, oh... two days or so before throwing 'em to kingdom come. Then I simply made a few jam-fit chucks to hold the wood until I could afford something decent.

    If you don't know what a jam-fit chuck is, 'tis basically a block of wood fastened to a face-plate or held in the normal jaws then hollowed out until the piece you're working on is a tight press-in fit. It won't hold as well as a steel chuck, but with a light touch you can still do most things. They also do wonders in improving your tool control.
    I may be weird, but I'm saving up to become eccentric.

    Thanks, gentlemen, your suggestions are all helpful. Don't know why I didn't think of them.

    , got a 2nd hand roughing gouge (not as big as yours, but this one is definitely HSS and not just stamped HSS).
