Right, my mill has turcite, but it also has big dovetail ways.... so he'd have to construct the machine that way to use turcite, or even box ways, that type of construction unless he has a machine large enough to make them, it can get spendy. Friend of mine made a machine with Teflon coated ways using dovetails, made of plate, it held 2 die grinders that would cut on two parts at a time, with a rack and pinion movement, single slideway, the customer owed like 5 grand for it, and was happy to pay it. Not to say it can't be done alot cheaper, especially if your just having the angled steel made.
And as far as haas, yes the motors hold it, because it uses pulse generators on the axes for movement, BUT the tailstock has a lock....
When I run my mill manually I don't need to lock anything...
