1. Yes, thas looking at it from the lathe side.
2. Not sure which photo you mean the Bush is threaded m16 and screws? into the backing plate? to support the shaft that drives the leadscrew. The drawing doesn't show individual thread points the same as it doesn't show gear teeth, this is a pretty standard drawing convention.
3. AF means across flats, pictures attached showing mine in its standard running configuration, one more gear is attached to the spindle and clamped with the handle, the curved slot is for the mounting bolt and the 4mm washer fits between? the machine and plate as a spacer on that bolt.

I think I've just about understood the 'unimat3 threading attachmentpdf' drawing, but have a few quick queries:
1) am I right in thinking that the plate is shown upside down in the drawing, and in use is rotated 180 degrees? So that the M16 threaded hole is at the lead screw?
2) in the photo of the components on the drawing it doesn't look as though the bush is threaded - is this because it isn't done yet, or is it not necessary to do so?
3) and finally, what does 17AF mean? As noted just above the bush. Apologies for my ignorance!
Thanks,
Peter
