I lost count of my scopes. Now I just want mobility. I came, I saw, I bought some interesting accessories, and put names to faces: NEAF 2012, ASAE 2012, SWAP 2013, ASAE 2013.

Thanks for that link. I like the idea of the box beam but I'm not sure if that's necessary for this size of dome. I may consider it though as it doesn't seem all that complex and it would be easy to implement that at this point since the rings are not glued together yet. Jared

Quote:Very cool domes! What did you skin them with? I considered aluminum but assumed it would be too expensive. I guess tin sheets would do the job too.

Quote:I think I have figured out a way to get the gores sized correctly.
Quote:Amateur radio antennas are typically aluminum with stainless fasteners. I have never noticed any corrosion when taken down for cleaning/tune up.
Quote:After my minor success today with getting everything figured out I just couldn't leave it alone. I worked a couple more hours out in the garage and have the dome nearly half way sheeted! Here's a shot of the exterior. Each half has 4 gores. Here 3 of them are sheeted. The area opposite of the shutter should be fairly easy (I'm hoping...what could be difficult about a rectangle??)The gores are held on with a couple of screws and a washer on the frame. At the top each gore has a couple of screws holding it in place as well. Here's a shot of the interior of the gores:I need to pickup another couple of piece of hard board tomorrow. Hopefully that will be enough for the rest of the dome structure. Jared
