I am looking for lens helicals with ~40mm diameter and 10mm displacement for an enlarger project. Do anyone know of a lens that have fairly "reusable" helicals for this purpose? I am sure some MF lenses would be perfect for this purpose, or perhaps something like the focusing mechanism of the Czech Flexarets.

I am also in the market for some CNC machine tools, so if the invest ment is not too steep, I might even consider making a few sets out of engineering plastic, but I have no clue as to what sort of attachments I'll need for such a thing. Any help would be appreciated.
