Ahh, full marks. I love to see quality stuff constructed from scratch.
Do you still have the dish? Is it still 'in service'?

Love this approach, but wouldn't have patience or probably accuracy of workmanship to achieve a working model. But suppose if I was stranded on an island, with loads of time would eventually achieve something. What kind of measurements would there be. Presuming centre focus would be simpler rather than off-set.

hi dohouch the dish i made is 1400mm,f/d ratio=0.4,focus 560mm,depth of dish 117.18mm.the equation for this is X=Y squared/4D(f/d)=Y squared/4x1400x0.4=Y squared/2240,where X= height of plot point and Y= interval of plot.it sounds harder to plot the measurement than it is.
