  • Certiflat weld rotator

    Discussion over at WTT, someone bought their (Certiflat's) new rotator, check it out if you've wanted something at a reasonable cost, reported that just over 100 units left at intro price of $240

    BTW I have NO affiliation with Certiflat

    Made one several years ago but I decided to look and see.

    Ended up ordering one as a kit.

    Arrival expected in 4 weeks - time enough to gather parts to motorize it.

    Here is what I made.
    Miller Dynasty 350, Dynasty 210 DX, Hypertherm 1000, Thermal Arc GTSW400, Airco Heliwelder II, oxy-fuel setup, metal cutting bandsaw, air compressor, drill press, etc.

    Call me the "Clouseau" of welding !

      Look forward to seeing your new unit powered up, does the old one still work?

        Yes but it doesn't get used much so I'm way out of practice.
        Will be interesting connecting a motor to the new one.
        Speed control would be a plus.
        Most likely I will soon be able to make sloppy welds in minutes instead of hours.

        Stay tuned for details...............

          I didn't go slogging through my Home Shop Machinist magazines to find it,but there are a couple of unpowered rotary welding tables in there. Acme Industrial Surplus (Where Wiley Coyote shops!) has many motor reducer/motor combinations. They're pricey, but it beats retail by a bunch.

          I concur with the comment about seldom used. I could have used one today, but that is the first time in almost a year. My main problem now is shop floor and shelf real estate. When something comes in, something else has to go out.

            Turntable project update.

            Bought the kit version not just to save $75 but for the fun of putting it together myself.
            Box was much heavier than I expected - a sign of robust design.
            Came in a USPS flat rate box.

            My local carrier was cussing me and asked if I had rocks in it
            Told him - not rocks just gold bars.

            Unpacked everything and took inventory as well as reading the instructions.

            As the parts are laser cut, there was a slight burr at the start and end point.
            A little work with a Dremel tool smoothed these out.

            First did a "dry-fit" to see how everything went together.

            Turntable is well designed and simple to assemble.
            Almost impossible to put it together incorrectly.
            The positioner base has slots of different size to insure it is assembled correctly.
            Idiot proof design - (perfect for me)

            A set of Harbor Freight welding magnets helped to hold the pieces in
            alignment and saved lots of cussing.

            Used my BuildPro weld table to keep pieces square and plumb.
            A plus is that the turntable has 5/8" holes on 2" centers which match my weld table.

            The gearbox fits inside the base so I first tacked the parts together first to
            check for proper fit and function.

            Then the final welding was done.
            Welds at the tab and slot locations are adequate as the design is well
            engineered and does not depend on lots of welds for strength.

            One glitch which was solved by Adam at Tab and Slot was that one drawing in my
            assembly instructions had 2 of the bronze bushings reversed.

            The correct orientation is shown on their web site.
            Adam has corrected the drawing in the assembly instructions.
            Simple fix and everything works perfectly.

            Used an old battery drill whose motor still worked to power it.
            Added a right angle attachment so the motor didn't stick out so far.

            Made a mounting plate using a piece of 1/4" x 2" stainless.
            Used the pivot bolt to hold the plate to the turntable frame.
            This way, the motor maintains it's position as the gearbox is tilted.

            Found a motor speed control on ebay for $5 and added a reversing switch.
            Full wave bridge rectifier on input side protects against reversed power polarity.

            Put all the electrical stuff in a box and brought out the speed control pot wires
            to an old foot pedal.

            Everything works on 12 volts DC so I use a battery charger to power it.

            Found a used 3 jaw chuck on ebay to hold stuff and voila !

            I now have another way to make sloppy welds, but this time much faster.

              Well done, no need to spend $1000 plus for a turntable
