Obsy progress
« on: November 20, 2015, 01:29:06 PM »
With the pier, base and floor finished I've been waiting for a dry day to get going again.   I've popped the scope on to check for levels and how high I should make the walls.   Reality matches theory so far and I don't need to change the design height.  Woo Hoo.

Its coming along well John. Will you be controlling it from the Obsy or will you be remote "a la Craig" in the warmth of the house?

The scope room is about 2 metres square and the end by the fence will be a 2 x 1 metre warm room with the entrance door.   There will be a sliding door to separate them and the inner wall will have a window so I can see what's going on.
I've taken inspiration from many builds on SGL but this one http://stargazerslounge.com/topic/119083-aorakis-build/  has the sort of look that I'm after.  My roof will slide off longways though.

Well, we spent this weekend in Musselburgh babysitting so nothing got done while the weather was good.  Back home now and its raining again so we'll see when the next opportunity arises.   A couple of dry days and I can get the framing finished then I can order the cladding.  There's no undercover storage here so I have to get stuff just when I'm ready to use it.

Yaay! A dry and sunny afternoon.   The chop saw had a bit of action and much sawdust was made.   I've started on one side frame but ran out of daylight.   Here's the frame half made then the cut wood stacked up before pulling the tarp over.

Well, the wind made short work of the tarp.   All the ballast bags (25Kg each) were rolled off leaving it to flap wildly.  At least it was still attached to the fence (I'd flattened the hooks previously).  I've patched one hole and re-secured the tarp with more ballast and also some wood to help stop it from trying to take off.  55mph gusts expected later tonight. Let's see how it goes.  ::)

At least it wasn't destroyed or sunk under 3 feet of water - got to look on the bright side.

In the last 30 days the weather has trashed two tarps and the third one has quite a few patches but never mind, a couple of days without wind and rain and away we go.

I completed the framing today and have clamped it into position.  It didn't need much faffing about to get it all true and square so tomorrow I'll be adding bracing diagonals to make it rigid.  Then I'll order the cladding.  I've chosen this stuff - http://www.shiplaptimber.com/products.php?idcat=1&idprod=73
It's tanalised and guaranteed 15 years which ought to be good enough.
