  • brass jaws

    A friend with an alternator/generator/starter business uses an old Atlas lathe with a tailstock Jacobs chuck for armature work. The Jacobs chuck has brass jaws that are getting very badly worn. Are replacement jaws (or a complete chuck) available?

    Check Atlas Press/Clausing's website.

      The chuck is a Jacobs #100 armature chuck. it was made as a steady rest for auto starter and generator armatures and other shafts that do not have a center provides.

      The jaws are replaceable, but I don't believe Jacobs supplies them any more. There was a manufacturer supplying replacements, but their website is no longer available.

      I have considered brazing them and machining them by boring, but have yet to try it.

        How about a "live " chuck on the tail stock?

        Seems to me I have heard of this before.
