I have to give all credit to the machining side of things to my good friend Chich, who has kindly donated his time and machinery to fast track this build, he had done in a couple of day's what I would have taken months to do... good on ya mate
First up is the tailstock, not too much to do on this, possibly it will get treated to a live centre, but a little trial and error will find that out.
Next is the cross slide, you can see where Chich has drilled and tapped out the end of the leadscrew and fitted a small bolt, then turned it down to suit the stepper motor coupling.
Last photo is the Z leadscrew, that Chich has turned down the end to suit the stepper.
