Greetings all; I've had a heck of a time putting the Z screw, some of which may be my own fault, and some David Clement's, who sold me the screws on ebay and vanished. Sorta. I found a message where there were instructions to dl the instructions, but they are behind a login that he didn't supply a username or passwd for, and his phone number is "suddenly" out of service.
Then 1-411 can't find a David Clements at 6330 N 15th St, Phoenix, AZ 85014. From the USPS Postage Paid label I saved. Short of snail mail, I am locked out of a way to contact him. Any way, the nut is big enough that it cannot be inserted into the post and then turned to face the correct direction to connect it with the Z slider. So I used the same plastic sleeve to hold the balls that one must use when installing the Y screw. But while that works for horizontal positioning, it is NOT large enough to keep the balls within the normal trackage in the nut, allowing then to run down and against the teflon seal, so when I screwed the bolt back in, those caught below the recycle guides, those little red plugs, went on down and forced the teflon seal about half out of the recess, and wound up dropping about a dozen balls into the post. Those I have corraled with a retriever magnet, all of which went on thru a 2" square hole in the bottom of the post, some on the chip tray, but more scattered about on the floor under and behind the stand. So now I have 2 problems, one being a pile of magnetised balls, which will NOT do, and the nut is one way, can only be turned to climb up the screw toward the top cover and thrust bearing. So, next is to back off & remove the adjuster nut at the top of the bearing so that the screw can be partially unscrewed, thread end below the top recycle guide, so that the balls can be re-introduced to the nut below the recycle guide. At least I think thats how it should work. I think now the loose bolts holding the nut to the nut carrier may have been a clue, because there is room, even with the grease zerk on the rear of the nut installed, to slip the nut bracket into position and fasten it to the slider, then bring it to the top of its travel & lock it down, then insert the nut AND screw, assembled from the top, and using long allen wrenches, put the bolts back in. A right Pain in the Ass but doable. If I restart 2 opposing bolts with one of those spring clip retriever thingies, then the bolts to the slider can be removed, and it all pulled back to the top of the slot where wrench access to the bolts from the top would be considerably less of a problem. Unforch, I now have the far end of the screw in a 5" vice, with about 5/16" of hard white maple as jaw pads, and the vice "snugged" up enough to crush the maple to the bottom of the ball grooves. And I still cannot move that locking nut. Its turning in the maple in the vice. So I assume it has some sort of thread-locker juice in it, but the color doesn't ident it to me. Faint, very faint, line of blue, maybe. So now I'll have to figure out a way to heat it hot enough to release that. I can find about 750F with my hot air rework station but with the mass of that screw, being in good contact with the thrust bearings, and them with several ounces of 1/2" alu, it will take quite a while, and maybe even a box to contain the heat well enough. Anybody got a better idea how to grab the screw, without damaging it, than what I've just described? Because of the steam in a propane flame, I'd druther use the rework wands dry heat. Or maybe a line of superglue at the maple/steel junction? But that stuff is hell to completely remove once set.
