    Anybody have any ideas on how one might retro fit a large dial drive using across the counter parts?:confused: I would like to drive a large dial mounted on the outside wall of the shop with the drive shaft from the tower clock. I need the step down gearing for the hour hand but would prefer not having to scratch build the gears/wheels. I would probably go friction drive for the hour hand if forced to do it myself.

    Any ideas??

    Thanks,
    Tom

    I have some numbers for OTC (over the counter ) gears, but it will still require fabrication. I will take a photo and try ito post it here before the weekend passes, if thats ok.

    That would be super. I can fabricate a whole lot easier than I can cut gears.:D

    Thanks for the help and have a nice weekend,

    Just got back home and read your reply. That is exactly what I was looking for. I'll check and see if the Boston gears are available and order a set.:D

    Thanks for the help!
