Observatory lacks door, so no valuables can stay overnight.

Beauty and the Beast.

 

Door arrives !!

It weighs about 200 lbs. Door perimeter is 3/8 inch steel box.

Stained and four coat satin sealed panels belie the impenetrable structure

The interior that Larry and I designed is a grid of rebar, welded at a 6 inch grid.

Of course, door knob and deadbolt will help it work better :grin:

:) 

My deepest apologies to those of you in the Southeast.

The observatory is to be completed by this afternoon. I will move the scopes in and commence with finalizing cable runs. 

There will then be 3-4 days of concentrated leak testing which may adversely affect your sky conditions this weekend.

I will make every effort to wrap this up before the new moon.

Friday and Saturday brought security.

Four roof toggle clamps (each rated at 300 lb capacity) were installed to keep roof locked when closed.

The two on the West side are angled to keep the roof tight against the West side stops on the rails.

The other two are neutral.

The door knob, deadbolt and receiver in the door frame have been added.

Doubt this door could be kicked in.

Lights over bench are in Red and White, plus I ran a red rope light around the south wall perimeter (but will need to add a dimmer).

The floor outlet boxes are a deep design that allows the plugs to be completely recessed beneath the covers with rubber gaskets to help keep out moisture and dirt.

UPDATE astronomers n the Southeast U.S.

 

Thank you for your patience during leak testing. During the past week, the observatory has been tested with over five inches of torrential rainfall.

In order to expedite the testing process, straight line winds up to 60 MPH were added on two occasions.

While some nearby trees were downed, they were not implicated in direct impact tests.

Attached File  16075002-large.jpg   36.77KB   24 downloads

In the interest of public safety, hurricane and tornado tests are on indefinite hold, but may be activated with little warning.

Testing should wrap up this evening with a 20% chance of additional leak testing. However due to the excellent performance of the observatory over the past week, testing tonight may be limited to tolerance of overbearing cloud cover.

 

All tests should be completed by tomorrow 10/16/14.

You will then be returned to your typical fall weather:

Days should be sunny and clear in the mid to high 70's - good for solar observing

Nights will be clear and cool with highs in the mid to high 40's with light breezes from the Southwest after Friday.

 

As promised, testing has been completed prior to the new moon.

 

Clear Skies y'all

This is the first time I've read this thread, and I've spent the last hr reading it from star to finish. After coming to Barkers Bluff twice to observe with you, I totally appreciate your observatory more now that I've seen it from start to finish. It is everything you have plannedfor it to be, all the way to enjoying the Dob deck for a break and enjoying and adult beverage, which we did the other night. I feel glad you and I have struck up a friendship and a few times a year get to enjoy what you have built. It is a very nice observatory!

Can I ask which brand/make you used for your roof clamps?  I have been looking for something similar on line but can;t find anything wit as long an arm - most seem to have a much shorter reach.

 

thanks!

 

Steve

Steve,

If you are asking about the toggle clamps, I found them on Amazon. The original arms were shorter but my metal guy added extensions (in the pic you can see a female female connector about mid arm). It is just a piece of threaded steel. If you mean the roof hold downs on the exterior, those were custom fabricated. The black pipe rail they mate with is just black gas pipe. I'll shoot my metal guy a text and see if he remembers the source for the extensions for the toggles. 

 

John

Steve,

 

Larry said threaded rod is sold at big box home improvement stores. I assume the coupler/connector is as well, but did not see it online

Thanks John. Off topic,,, that cut out on the pans I asked you about. I figured out what it's for last night using my son's 70 mm. For it to seat all. The way in the diagonal, the locking screw on the diagonal that locks the ep in place fits into that slot. That's the only way the ep can rest fully into the diagonal.
