If you guys don't mind, I'm going to keep posting the progress. Lots to do yet - flooring, pier, and all of the extras that go with it.



Mind? We would be very disappointed! We want to keep following your progress! :bow:

What are you guys doing for dew/humidity control??? At the moment, the OB is sitting on bare ground with no ventilation - I've gone in there a couple of times in the morning hours and it's like walking into a rain forest, and the entire dome and walls are covered in condensate. I would think that by getting it up off the ground with 4x4 posts and a platform will alleviate most of this problem???

and possibly a vapor barrier if not on a slab.

I would recommend looking at a product called schluter kerdi,

http://www.schluter.com/8_1_kerdi.aspx

It is a fabric from Germany I used in my shower. You can attach it to wallboard, concrete, wood, anything. It creates a water barrier that is virtually unmatched. If you make a base of concrete, or wood then a layer of Kerdi, with a top layer of concrete, tile, stone, wood, whatever you want your floor to be, you will have no moisture from below. Then add a cut out square or two in your walls and place a vent screen for keeping out criters, you will have solved the rain forest problem.

We got our first two MAJOR storms yesterday. I checked the inside for leaks/drips, and had no water intrusion through the dome & shutter. Good sheet rain with high winds. Shutters are holding tight, etc!

Hey,

I was showing this post to my dad and he expressed a lot of interest given that we live in a farming community and it's likely that many probably have these laying around. I'm also highly interested in the idea as I've always wanted an observatory, and my parents have always told me they would allow it since that they're not very happy with the southeast corner of the lot (below image, and it's actually kind of convenient given that it's closest to the middle of the field and away from any trees nearby). As i was showing my dad your steps he thought it was pretty sweet, and the end result appears to be clean and admirable in appearance (much better than a pile of old dead limbs and odds and ends).

I was curious as to what you're going to coat the door with that you covered with wood which you bent over the top. He was as well, just to keep it weather-proofed.

Hey! Thanks for your interest! Actually, what I did was use one of the reinforcement ribs as kind of a drip edge for the door. The corners stick out a little and for longevity, I really should either cut them back under the fiberglass, or put a layer or two of glass over them.

Hope you can locate a tank, and you're welcome to ask any questions - hopefully I can help.

berlinstar,Just wondering if you have been able to get additional images for the interior of your dome build?
It appears that it has been quite a while since anything has been posted. Thanks
