Warco WM14 Z-axis power drive?

[Greg Smith 4Participant @gregsmith4]

I have a WM 14 and due to arthritis in my hands am finding it increasingly difficult to wind the topmost main vertical adjustment wheel on the z axis. The larger models have it coming out of the side. I am wondering if I can put a motor on it to make life easier. It is just to move it up and down to within range of the micro z-axis feed.

Best options for Z axis main height adjustment feed?

[Nigel Taylor 2Participant @nigeltaylor2]

Yes you can – I have done it and wouldn't be without it now.

[Greg Smith 4Participant @gregsmith4]

That looks just the jobby, well done

Is that a Nema 34 you have used with a belt drive?

Did you post a thread on how you did this, if not any chance of some specifics please?

Have you put one on the x axis as well?

Hi Greg I found reaching the back handwheel on my Chester champion 16v with same set up. I made a 90 deg handwheel with bevel gears and a motor on the end of the leadscrew which I replaced with a ball screw. There is an artical about it a few years ago on here.

There are a lot of pictures in an album in my pictures Chester champion v16 mods and the drawings are free if you want them.

Greg –

My setup has a NEMA 23 stepper motor driving the toothed belt, the pullleys are 2 to 1 ratio. There is a 24V, 6.3A power supply and a DM542T stepper driver There is also a PWM signal generator board in the black box, with the switches remoted to the outside. All the parts were sourced from eBay sites.There is a microswitch to stop the drive once the head of the mill is at the top of the column, the 'override' button disables this to allow the head to go back down. The 'max' button overrides the speed setting.

I found a circuit diagram on the 'Myfordboy' website which helped with the wiring. I originally bought all the parts to fit to the x axis, as Myfordboy had done, but changed my mind as to which axis would be most useful to do first. I have still to do the x axis…
