    Hi Guys,

    Just after some input from anyone that may have used the new Dual Shaft Wormdrive gearbox, as per below:
    (MotionDynamics in AU) (50:1 / 60:1)

    How are people mounting their levers to this gearbox?

    I was thinking of some kind of collar around the shaft, with a large screw through those holes.... ??

    I have @Archie and was concerned about the strength with such a large existing bolt hole through the shaft.

    So I had a custom machined tube made that is an interference fit, with a step down ridge to clear the gearbox housing and stepped up to provide more material and support for the securing bolt.

    I could not get away with a shorter tube but if I could have I would have also have used a securing bolt horizontally in the end of the gearbox shaft.

    Excellent. I had the same in mind. I was going to blow torch a 20mm tube and hammer it onto the shaft to achieve the same, with a bolt going through.

    I was hoping to sort something out without dragging out the welder. Oh um.. :)

    Actually @noorbeast , do you recall the ID of the tubing you used?
    And what the ID of the interference fit you ended up with, was?

    Thank you.

    Yeah, checked that out before I bought them, as I was thinking about what to do when I got them.

    Thanks heaps.
