Motorizing the Z axis handle would be much more in keeping with the machine, but you would never push the boundaries that way.

Would you like to have the z-axis I'm ripping out? It's much the same as the one that's going in but a lot less beefy and made without the benefit of cnc.

One more set of pics and the operation should become clear.

Robin,

I'd be happy to get a reasonable degree of accuracy, not interested at pusing the boundaries at first. Cost is still an issue, but if i am going to invest a few £100 in ballscrews etc. I need to be comfortable I know what I am doing and I have a reasonable chance of success.

I may well be interested in your old Z-axis... its still likely to be an order of magnitude better than anything I can produce (yet).
