Hi Clive,
looks like you ticked all of your boxes and have satisfied everything
you wanted. That's rare in any permanent setup. Like you said, it is
not until you complete a venture like this that you find a niggling downside
but it's all good experience, and for us builders, a lot of fun too
I have two suggestions, firstly, I used green colourbond fencepaint to
paint my dome...and green was a very hot colour in the sun.
I know green makes the obs blend in well but it's not the best choice
for me at least....i changed it to 'primrose' cream colour (Solarguard)
Secondly, I'd hate to see you come a cropper by tripping on something
near the scope and falling down the larger drop of your sloping block.
Is there any way you could incorporate a thin gauge set of handrails
on the deck?
Superb stuff..
Steve
