FYI: Found the original BRAMI VISIOLA patent- Harry this French Televisor from the 30s is a great find because it shows that a mirror screw does not have to be humungous in size. Simple motor, phonic wheel for sync and a led line lamp. A small handy 30 line demonstrator -thats what it would be without the need for a 50 cm diameter Nipkow. And the screw would be of a printable size.
In the Brami disc they kept the slats as a pack, polished the edges while the slats were kept in a jig and then they used the stepped edges for alignment with another special jig. Have a look at the drawings...perhaps the stepped edges could be made in such a way that the alignment is almost automatic.?
Once the thing is aligned the slats can be fused together. I think by the time I get home you'll have a 3d printed mirror screw!
Interesting how they put the slats into a cylinder with spirals cut out of it to alight the slats, i think i might draw up a model in Autodesk Inventor, give me 2 weeks and ill have access to a laser and plasma cutter, and one of the largest CNC mills on the market. Then ill start making some metal slats! But first, the parts for my televisor shall be made.
