    Simple lathe mandrel dividing

    When you only need to make spanner flats or a hex on a part it is not worth while setting up a geared dividing head for the task.
    Since I have divided my chuck backplates by 60 indexes, a simple indent is all that is needed, this bolts to the lathe bed with a springy arm with an indent and is quick and easy to use.
    Also handy for drilling radial holes etc using my drill / mill spindle.
    Base and clamp is alloy and the arm is s/steel (part of a UPVC window hinge).
    Shown is a typical use for this in making a motorcycle steering stem nut.

    I like your back plate mode and indexer arm. Very quick to get it into action. It is on my ToDo list.

    Cheers, JR
