My observatory build (felt left out :p)

Used 10mm here.......no flex in that.

Ditto.

Thanks for the input everyone... Don't suppose you know a supplier do you? Looking for 200mm x 200mm ideally.

Thanks

[The_PSY3NTIST]

Bought 4 x 200mm x 200mm x 5mm plates. Going to bolt and weld them together to add strength. Couldn't seem to find 10mm at the size I need.

[The_PSY3NTIST]

So after your recommendations... Here it is, 2 10mm x 200mm x 200mm

Time to get welding

Window in and pier built, just the plastering and the roll off roof to tend to

I got my 10mm thick ali from ebay.

I opted for steel in the end just for ease of fabrication. Some good paint should do the trick to keep it corrosion free

After a long break from doing anything with the shed I'm going to have a day at it tomorrow. I have a question though ....

Will a 4' x 8' opening be enough in your opinion? I'm only using a 150pds and a small frac so will be able to get the pier high. Anyone using a small opening like that? Trying to keep costs down and use a sheet of 18mm ply that rolls off. Any help much appreciated

6'X6' here and my roof is 11mm OSB with heavy duty felt, nailed and glued at the joints.

My roof is flat with a slight cant to one side and is two sheets of OSB 2400X1200.

This gives me a nice 9inch overhang all round, the roof frame is 70x45mm C16 treated timber.

[The_PSY3NTIST]

Thanks. I have room to do 6' x 6'. Sounds more logical, guess I might as well do it right first time for the sake of an extra 30 quid. Should be fun tomorrow cutting the existing roof out with a jig saw :s these clear skies have have me my second wind. Loss my enthusiasm with all the rubbish weather!

Up and running at last! Took some getting there and still lots of finishing touches left to do. Thanks for all the help

Congratulations David, and enjoy your new home

[saac]

Well done David, I've just got mine to a workable stage but like you I have a list of finishing touches.  I'm thinking that the finishing touches will be ongoing!  Here's wishing you good use and plenty of clear skies.

Thanks just need a good clear night now get the polar alignment spot on. I will be so happy when that is done for the last time! Just need to find the program to perfect it. Heard of a couple but not sure which is best. Any ideas anyone?
