    Sorry for the wrong advice. I am glad you have it open now, next time it will be easy! What are
    you going to do with it now? Clean it, or is there something not working.

    Terry. I am enjoying this build as much as all your others. I was looking at the beautiful work
    in the heads and a thought passed through my mind. Just think how good a Knucklehead radial
    would look! ...

    I am going from memory. And looking at the drawings in your duplicate post , i suspect the dial
    plate is held on to the body with glue/double sided tape. I would put a small hook tool through
    the hand...

    Sorry , there is a retaining ring around the edge of the dial that need prizing out. The dial
    plate is thin.

    You need to pull off the hand first. it is a press fit. You almost need a special puller so as
    not to damage the thin dial. There is a recess in the center that dose not support the dial.
    Then the dia...

    You really need a s Coventry die head in a lathe to get a good thread as well as a good cutting
    oil. Dies don't cut good threads. They do cut acceptable threads though. ot get somebody to
    machine them...

    Yes , that is the motor driver. you still need a step and direction pulse generator and a 10
    amp dc power supply 24/48 volts. The pulse generator can be a PC, aduino or the other board in
    my first pos...

    It has the advantage that there is no extras required,like programming or PC. I have two that
    have run hundreds of hours on an industrial machine. They also switch on from "cold"
    instantaneously.

  • Posted in thread: CNC advice please on 03-19-2018 at 09:01 AM
    This is what I use . It has forward and reverse as well as start and stop. Also oscillate
    between forward and reverse. You will also need a 48 volt power supply. The prices are for
    multiple pieces, 2 ...

    You have pretty much got it. A small tip radius and straight sides to the tool and enough
    clearance below and almost any thing will machine properly. Top rake of a few degrees helps on
    ferrous metals ...
