Thats your fault. :) I don't have a winders box anywhere in my zoo. And at the instant, my only problem is flashplayer. Its installed, and visible open the about:plugins page of all 3 machines with 10.04.4 LTS installed from our own custom linuxcnc install cd. But it is not working, either for firefox or the freecad tutorials which are in flash. So I have a chicken/egg problem. And I'm attempting to carve a functional nut holder for one of Steve's 8x2.5mm ball screws. $64k question for the steel heads here. Steel is assumed to be about 1016 or thereabouts. Room in front and behind the nut itself is crowded. I intend to machine the holder so its a press fit over the nut & screw with perhaps 50 thou of this steel left on each side of the nut so that the sides can help brace the end bulkheads by coupling them together from one end to the other. Since it has to fit over the nut and screw, it will be slightly flexible width wise. This coupling 'strap' will be machined about 50 thou narrower than the diameter of the nut, but with the sides cut away to allow it to spring closed up with the sides of the nut projecting out into the window in each side, which also gives the cutting tool a chance to square up the recess as I don't think the 1/8 diameter inside corner I can carve from the bottom presents a suitable seat for the end of the nut. Going slow, thinking about how best to do it. The nut holders ends are wide enough that I can drill & tap for 2 8/32 screws in each end to attach it to the bottom of the cross-slide. Since the steel against the ends of the ballnut subtracts available motion that will need to be retrieved by machining clearance in the carriage top for the mounting ears etc of the nut holder, my question is: Have I given enough of a visual description to allow one of you to say how thick a root the end 'bulkhead' needs to have where it is the brace against the reaction forces of the screw, which I've assumed will be (under fault conditions of course) somewhere north of half a ton? > I have got to make a couple of > cat 5 cables. to get to the shop.
