Thanks for that Piersdad, I felt that the stability would be there, not a problem to turn it just needs thought. Anyways that is sufficient to stop me thinking about it as it appears there was some merit.
I also "invented" a "trumpet mirror lens" and posted that idea on astronomy daily after a few people questioning the possibilities someone announced that it was this set up used in the Chandos?? X ray scope in Chille. Although I was disappointed to find it out there it was satisfiying in so far as my idea was viable. I gave up on the idea because it had been done but recently I have been thinking that if one used such a set up for a scope optical purpose the resolution to app. would be excellent and presumably superiour to current telescopes. My idea was to reflect the gathered light from the "trumpet mirror" via a convex mirror to a camera.. if one could produce these they would (i believe) be superior to current approaches to light paths. And that says to me commercial opportunity (for someone else) I wouldnt have time to bank the money. As a mate said to me when I was working on the hollow rod... "mate it doesnt matter if it works if is new everyone will want one. That offended part of me but I realised there was some truth in that statement. Production of the "trumpet mirror to me is impossible but maybe the son of a tollerant engineer would not find it so. But on my humble (caveman like calculations I think the mirror could be sperical as opposed to parrabolic.. an aspect that I would think would make production simpler. The mirror reflects the light at a sharp angle like a stone skipping on water and I see major advantages both in image quality and wave tollerance. A ruff trumpet should beat a super reflector set up hands down. I will check the observatorys name and post a link to details of their mirrors. I would be interested in your opinions as to the practicallity of constructing such a mirror.
I wish I had gradchildren I have two 30 year plus kids who havent produced one yet.. So I am hoping.. I have a 7 year old daughter as a gene pool back up.. sortta a late life surprise ( i,m 57 maybe 58?).
And taking about it being done before I invented a paddle which when pushed out from the back of the boat propelled it and folded in for the back stroke.. I built one and it worked very well.. however I saw some old Chinese drawings and saw what could only be my paddle there.. and it was a 1000 year plus drawing.. so what can you do. I gain satisfation however seeing things already out there, like the mirror the flying ring because it makes me feel less of a dreamer.
Thanks again I will track down that link.
