Billys Observatory... the next stage...

Postby psychobilly » Sun Jun 29, 2008 1:50 pm

Funds are tight so its bits at a time...so its scrounging time... managed to scrounge the timber for the frame...

Decided to get some walls up so at least I can rig a temporary roof when rain threatens...

Only the first fix of the timber structure so far...

12 sided aligned 12 o' North wwill haev double opening doors between 5 and 7 o'clock..

2.4m internal min diameter... to 1.5m high...

Framing will either be covered with shiplap or might use a couple of layers of 4-6mm marine ply on the outside rockwool filling and thin ply on the inside... see what I can scrounge...

Dome for top will be the next item to design...eventually...Thinking of a 12 segment design... with a center hole for the zenith..

HI Brian,
Its amazing the amount of brand new wood that is thrown away in skips.I normally use it for kindling but even some used wood is good.Its would be largely a matter of luck if its the stuff you want and if you relied on it for a observatory building project you might end up with a observatory looking like it was made with wood from a skip.[:D]
Regards and clear skies Les.

The quality of the scrounging depends on the people you know...

My brothers a builder ;)

Used as much scounged clading as i had - 2 slightly different styles.. got about half of it done...

Looks great Billy. Just out of interest, what's the pier, and how is it connected (to a bl**dy great lump of concrete) at the base?

Can I make a suggestion before you go any further - leave a gap at the bottom for air to circulate, so it doesn't turn into an oven in sunny weather, also help to keep the temperature stabilised when observing. You will probably want to cover the gap with wire mesh to keep small furry critters out.

Hi Brian,

The pier and fixed wedge (actually +/- 1 deg adjustable in Alt and +/- 15 deg in azm) is another of my projects lucky to have soem very useful contacts it laser cut from 10mm steel plate and has been "professionally welded" currently its about 2 mins out in alt and 12 mins out in azm it will ahev a final tweak once the observatory is finished but I find this is pretty good when I am autoguiding...especially as the scope is mounted and dismounted for every session


With regards to the ventilation iI will be fitting sliding louvres into the bottom sections once its all clad..

Need about another £120 worth of cladding to finish the walls to the dome ring level...my brother gave away 12 lenghts about 2 months ago :(

Then need to make the double doors and start thinking about the dome design...and the rotation mechanism...think the laser cutters will be busy again thinkign of stainless steel running plates between plywood rings with ptfe bearing surfaces or maybe roller bearings...got a load here from old industrial sliding doors...

These two threads covered the foundations and the pier construction...

Must say it looks a damn sight better than one of those off the shelf jobbies. Nice work. Think the fiance might even agree to having something like that in the garden. If i can stop losing bits of fingers in the presses i might even give it a go.I could paint it bright colours and pass it off as a wendy house, you think?[;)]

Thanks all,

As I am not intending to leave the scopes in-situ , I'll probably only get the walls finished over the next few weeks. The dome and doors may have to wait..until the camouflage (hedege) catches up and the "locals" get used to it [8|] and for funds to be re-plenished [&:]

Will make a lightweight roof using the flexible carbon fibre poles from the £3 beach bivies I bought that I would be able to put up quickly when rain approaches.

TTFN
