Quote:Bill,Quite a fertile post on your observatory. I offer these 3 tips: 1) your deck framing has double "X" braces only on the ends, you should have them also on the long sides. 2) Standing seam would probably be the best choice. 3) In southern Indiana, snow can be a problem. I would recommend a steep roof pitch, like 6:12 (6" height for each 12" on the base). I am going to guess that your garage in your 1st picture is about 3:12.The ARP GuyBill Pickard"The difference between Stupidity and Genius, Genius has its limits." Albert Einstein
Quote:Bill,Looks like you are making good progress. Some observations:1. In building, shear is resistance to lateral forces. In California, we are concerned about earthquakes. In Indiana I think your concern is winds. Your are providing shear to the building with the plywood siding. But the only shear on the deck framing are the front-to-back diagonals. There is no resistance to lateral forces left-to-right. You have provided temporary diagonal braces left-to-right to the roof track and permanent diagonals front-to-back. I would recommend permanent diagonals left-to-right on both the roof track and the 6x6 posts. You will have a substantial amount of weight from the deck up which will make the structure "Top-Heavy". A big wind could provide you with a lot of firewood.2. A boat winch is a great idea especially with the twin-ratio they provide. Perhaps 2 will be needed: open/close(?). The main concern is reduction of friction rather than pulling power. Perhaps a gloss-powdercoated steel C-Channel on each track with (3) 4" poly ball-bearing wheels on each side (in-line, not swivel) would provide very easy movement. You could even install windshield wipers in front of the wheels to clear the snow on the track 3. Standing-seam mfgrs would recommend 2:12 as the MINIMUM slope to prevent water intrusion. 4:12 should be sufficient as the area is maybe 96 sq ft (8'x12')4. Have you provided power? Coffee maker? Heater?Looks great. Bill Pickard"The difference between Stupidity and Genius, Genius has its limits." Albert Einstein
Quote:Diagonal braces for both are in the plan and I just need to settle on the exact detail regarding these supports; combating lateral shear from side to side is the primary objective
