Looks good Just a question, how will you protect all that metal from corrosion? Also, if it is something you have to paint or spray on, wouldn't it make more sense to do it before putting on the wall panels?
Just my 2 cents

Most of it is zinc-coated or galvanised. The raw steel will be painted with rust-guard.The outside under the wall-panels has already been done.

One small task at a time. Today my goal today was to build a door frame and door to fit it, out of steel.
Done.

Marking out the flooring for the top floor ready for cutting into a whopping big circle!

Swept and tidied, a bit of an idea of the space that will be available in the office downstairs.

Cheers Jon!
Finally got the last of the heavy bows on the roof. I've been at it for roughly two hours every afternoon after work until I run out of light. I've even come home at lunch times to get 30 minutes of labour in at times. Time is so precious.
The next step is to roll-form some lighter intermediate bows. Flat sheet to cover the dome will bend nicely one way, but not two ways, so trying to bend it over the large area between these heavy bows is likely to warp and distort them too much. Putting in some intermediate bows will mean thinner strips of sheet, reducing the need to bend them two ways.

More steel coming this week and enough cash to get a roof on! Can't wait to get a day or two to build!

One of the hurdles I've had to overcome is that the old pier is not high enough to mount the telescope on, as the new floor level is now much higher.
To solve this, I have built another wooden box like the one underneath, to be filled with reinforcing mesh along with some conduit to run electrical cabling. It will then be filled with concrete.
Full story [URL="http://www.asignobservatoryii.com/observatoryconstruction.htm"]here[/URL]
1. Constructing the form-work for the new pier.

2. Form-work in position on top of old pier.

3. New pier extension topside.

4. While I was at it, I skinned the door with thick steel sheet.

The race was on today as the rolled steel arrived to build the dome's sliding doors and complete the intermediate dome ribs. I say, "race" because tomorrow afternoon I have a professional welder coming over to weld stuff together.
This afternoon I measured, cut and joined all the framing together for the sliding doors. I have used 20mm steel plate to join it all together with screws, that way the welder can just weld all the joints together, then I can remove the ugly plates and screws.
Below: Picture 1 - One side complete. Picture 2 - The two halves will split sideways to open the dome slot.

My welder friend gave his valuable time and skills tonight to weld up the door-frames as planned. They are extremely rigid and strong now. Great job mate.

Putting up all the intermediate dome ribs was so much quicker than the heavy ones. I got a couple done yesterday at lunchtime, a couple more in the afternoon, a couple more today at lunch time and the rest done this evening. I even had time to paint the door with primer.
Below: All bows up, ready to be welded in place and then the temporary joining brackets can be removed and the roofing can go on.

My pleasure mate! It's great to give back to a community that avails folks like myself to ideas and information on how to go about this, from the ground to the sky.

I've been trying to work out how to get the doors on top of the dome to slide sideways, without leaving protrusions outside the dome when it is closed. My uncle came up with a solve consisting of four bearing-slide-rails from industrial sized photocopier paper trays. I now have them and they look and feel like they will do the job nicely. I'll put pictures on the website when I have them figured out. Today I got my welder friend Jacob to come over and weld all the ribs on the dome, so I can take off the cumbersome steel plates holding them on. Now I can start getting some sheeting on the roof and seal it all up. I've bought some cement and hopefully this week I can mix enough concrete to fill the central pier extension. With that in place, the telescope can be mounted as soon as the roof is on and operations can begin! All the prettying up on the inside will follow, but at least I can start to use it. My next-door-neighbor is a carpenter and has volunteered to help me build the stairs inside. Actually, he is the expert, so I think it is me who will be helping him!
