  • Source for machine dials.

    My mill is missing both indicator dials on the long feed. One side has a servo feed and the other is just not there and doesn't have a handle on that side. Anyone know where to get some dials the right diameter? I can machine the ID but I can't find any that match the OD. Don't know the pitch of the leadscrew. It's a Gorton 1-22. I cleaned it up and greased it today. I think it's gonna be a real good machine!

    Seems like that Sherline has some nifty replacemant dials in Bridgeport size, maybe they'll be able to give you some dimensions.

    I built a larger set for my Atlas shaper, with a 100 tooth gear lashed to the lathe spindle and a shot pin to make a rough and ready indexer. Turned out pretty nice, and I can read 'em

    I cut it off twice; it's still too short

      Anybody know if Winfred Berg is still in business? At one point I think they would make custom-graduated dials (at a price....)

      But if you have a rotary table or dividing head, it's possible to make your own dials. Tedious, but not *that* bad to do. Or you could do it on a lathe, if you can figure out a way to index the spindle. There's a bunch of ways of doing that, from setting up a gear train with a detent rigged to index on gear teeth, to mounting a disk with a length of bandsaw blade wrapped around it with the correct number of teeth. Scribe the lines with a sideways toolbit, racking the carriage back and forth.

        I agree with SGW and suggest you just make your own. It's not too tough if you can figure out a way to index the ring. It's not nearly as critical as, say, cutting gear teeth that need to mesh. You just need a visual aid and if the occasional line was .005" off it probably wouldn't be too noticable, if at all (.005" on the dial might translate to .0001" table travel - not bad for a hobby mill). Use a dial indicator on a mag base to help in making the graduations the correct length (and for other milling until you get the dial made).

        Most full size mills have 5-pitch lead screws so 1 rev = .200" (this is true for my 1-22). If you can find a cheap, small gear with 200 teeth, you could use it as an index plate and rig up a simple indexing jig (a 100 or 40 tooth gear and some careful adjusting in between might work well too). There are a few other ways to skin this cat too and others are likely to chime in. I remember seeing a web page that showed a strip of paper with graduations ink-jet printed and glued onto a ring as another solution. That might work temporarily at least.

        Here's a "schematic" drawing of an indexing jig I did for someone a while back.

        p.s. Since my 1-22 is a different vintage it might not be identical, but I can make some measurements if you need them. Let me know:

        p.p.s. Oh to hell with all of this. If you're anything like me you'll be jonesing for a DRO soon anyway. If you find two, send me one!

          MSC sells individual ones and sets in black aluminum with white dials.
          But like said check the screws,I have seen two old b-port clones with dials that were 1rev=1.250",PITA to make a count on to BTW.
          I just need one more tool,just one!
