Ok, I am going to build a run-off shed and need an idea as to how to
make the slide-off roof slide off, without being flimsey or too
cumbrous to move. Is there any one here who has made one and can give
me some tips, on what to do/ what not to do?

I looked in the first edn. of Moore's book on observatories, but that
does not tell you HOW to make a run off roof, run off. It has plenty
of images of people's observatories, but little on the technique
behind their construction, and it that which I need!

Any help would be greatly appreciated!

I recall seeing exactly what you want in a UK website last year.

I have a strong feeling the owner was Northampton based even though the
observatory was in East Anglia.
