Hakann 2 Posté(e) 5 août 2020 I have a Quartz 18 f/4 from Carl Zambuto I plan a std 18 points classic cell and the triangles will be in carbon fiber. It will be a low number nm RMS but I don't like what I saw in others 18 pts cell where 1 triangle can be loose or bend harder into the glass. I will use the flexuare edge support, so is 120 degree best or 90 degree? So 3 triangles will be like a hard dots (and where I plan collimate cell at ) and the other 3 triangles will be astatic. I read on Frederic Gea's web, that it was 2 versions (maybe also more ) of this system. So question will be, how will I solve the movement the best way. Bearings and a piston or the bronze plate and the 'chrysocal plate'? (or another good idea?) If I read your text it has been some upgrades - so what is the best way solve this? I also did note it was said the plate and 2 L-irons there is no 'piston', but on this picture on the web it is a 'piston' even at the chrysocal design (where pin goes up to the triangle) I would appreciate if someone her familiar with this systems can help me with some advise here!
