I have taken over the support of a MicroLux 7x16 mini lathe at Fresno Ideaworks, our local makerspace. Prior to my involvement, someone had taken off the lead screw. When I got involved, a lead screw was laying in the chip tray which I assume is from this lathe. The right end support bracket was there, but not the left end bracket. I ordered a new bracket from Little Machine Shop. Unfortunately when it arrived, more issues were found. The left end 60mm of the lead screw is 10mm in diameter, the hole in the new bracket is 13mm, and the hole in the gears that are supposed to mount on the lead screw is 12mm (see attached images). Obviously, a 10mm shaft cannot be supported in a 13mm hole nor can gear with a 12mm hole mount on a 10mm shaft. Among the pieces is what looks like a broken sleeve that might have been on the end of the shaft to mount the gears, but not sure. If anyone has one of these lathes, could you take a look at the lead screw and tell me if the left end is a simple 10mm shaft, or if there are steps in it to mate with the mounting bracket and the drive gears? If it is a 10mm shaft, how does it mate with the bracket and with the gears? Is there a bushing in the mounting bracket and a sleeve for the gears?
I have inquiries in to both Micro-Mark and Little Machine Shop, but so far no help.
Thanks in advance for any information you can provide!
