    Default Hercus 120 tooth gear

    Hi all, I am chasing a genuine 120 tooth cast iron Hercus transposing gear, I have a coupe of 127 teeth, just need a 120 to make a metric to imperial set. Would also swap a 100 for the 120 if that works for someone as well.

    Cheers Steve

    The metric/imperial translation set I have is a 100/127 tooth gear set. I think 127/120 is "non standard." My opinion - just my two penneth worth.

    The 127/120 is for the metric to imperial, as asked for above, the 127/100 is for imperial to metric , both are for 9's.

    On the metric 9" the 120 mates to the stud gear and the 127 drives the gearbox input as per the English thread chart
