Thanks Dale, A good idea but not workable in my case I'm afraid. Have you tried pouring hot metal into a 0.5mm hole? Almost all the work I do is on antique watches and marine chronometers and so the screw sizes I deal with are from about 0.3mm up to 3mm. That is why I resort to cocktail sticks and mouldable plastic which can be forced into the hole easily. For the bigger screws I do also sometimes use one of the hard modelling waxes such as dentists and jewellers use and this has very little shrinkage but, in reality, at these sizes, the shrinkage of anything is almost unmeasurable.
Now I'm set along the line of using a stepper motor to drive my lathe spindle, how d'you reckon I might be able to get it to turn continually like a normal lathe when I'm not wanting to use it for screwcutting - i.e. to do normal turning? Am I going to have to set up another separate driver and pulse generator or is there a way to persuade EMC2 to set one axis going and then ignore it while running G-code on the others? -- Best wishes, Ian ____________ Ian W.
