  • OT: Lathe topic - Thread dial

    Sorry I haven't any health, marriage, or child support problems to discuss 8*D

    The one thing I miss the most on my Grizzly 3-1 lathe is a thread dial. Anyone have any suggestions on how to gin up an add-on?

      That's a thing of beauty, Russ. Never occured to me to make one from scratch but that is damned inspiring. Time to think about an indexer, too.

        Not wanting to hijack dp's post but the first person to email me the specs of the SB threading gear details gets a free one.

        Need to know OD, width of gear, width of boss, diameter of boss, bore and whether the leadscrew is RH or LH.
        I know what they look like from Russ's picture.

        $64,000 bonus question is will this fit a Logan?
        If not same applies, first picture and same details by email gets a free gear.

            Revisiting this got me to wondering if that drawing is still around? After ogling my Griz for a bit it seems quite feasible to add such a feature. The messy part would be the gear but I have a lot of hacksaw blades and plenty of time.

              Don't know, not familar with that make.
              Do they share a dial? if not which model is the most popular.
              It is all really determined by the leadscrew.
              If they are 8 tpi then the dial is 32 T so the OD should be 1.393" and the helix has to match the hand of the screw.
