    All done for a customer, don't know what they cost but they will be in Arceurotrades catalogue or website.
    Don't want to start advertising here, posted more as an interest post than a commercial one.

    Are you selling these or did you do them for a customer? What would something like that cost to buy?

    All the rotary table you buy nowadays have been simplified at the expense of cost. where they used to have bearings and thrusts on the worms got changed to bushes and thrusts, then just bushes but now just a worm running in an eccentric carrier.

    Some are steel in cast iron, may are steel in steel.

    These come in and are stripped, deburred and cleaned up.
    Then the carrier is shortened by two thrust thickness's in length and bored to take needle roller bearings so the worm is now fully supported thrust either end and needle rollers both ends.
    Stepper mounting is made plus part of the Oldham coupling that also serves as a pre load nut to save space.

    Greased up, assembled and test run, then shipped out. Normally there is about 2 - 3 days work by the time the motors are wired but these have taken a bit longer as emergency jobs have been shoehorned in between.

    Let me guess....John made the adapters to fit the stepper motors to the rotary tables and then fitted the stepper motors that either he supplied or the customer......

    Am I close?

    I think I see some uncharacteristically clear space on the floor - were you visiting another shop for this picture?
