Well, I finally got the canopy started. The framing is about 80% done! I knew the limitations I had to deal with and realized when the lids are moved that 18" is truely the maximum height. At no tiome can the canopy exceed 18" while the lids are moving. Well, I'm happy to say that the lids barely break 17".
I still havn't verified the ceiling height, but I should be able to do that tommorrow.
Now, onto the pics.
1: I knew what the basic concept of the frame was going to be reagardless of how the lids open, so I started putting it together. The first images is just four pieces of 2x4 tied together. Not much here yet.
2: I put the first lid on. The lid you see in this pic is at the back of the canopy. The two little pieces of 2x4 that were added are only there to help prevent light from esacping and lighting the ceiling.
3: Well, pic 2 is what helped me realize how the lids have to be designed to move around. it hit me like a ton of bricks when I figured it out. Actualy building the canopy up to the state that image 2 shows was of great benefit as I took some of the hinges and started playing with ideas. Anyways, here's another pic of the construction progress.
4&5: The following two images shows the framework at about 80%. As far as how the lids operate, you get to see 100% of the solution. The mid and front lids fold onto eachother and move to over the top of the back lid. The little pieces of 2x4 serve 2 purposes. One is that they help hold the hinges better. And secondly (the true reason for them), they will allow for the lighting ballasts (electronics) to be placed on top of the lids, while still allowing you to fold the front lid back on top of the middle lid. The lids still need a little bit of work, but the mechanics beind there operation is obvious. Image 5 shows the middle and front lids folded back as to allow me to maintain the tank once I get it set up.
When the front two lids are folded up, About 2/3 of the top of the tank is open to give me room for maintenance.
As a sidenote, I ordered my lighting from AH Supply today 7x55 watts + 2x13 watts(for moonlight)
- go there and see my future fish section to see what I have planned for my next 100+ gallon tank.
Note: I havn't maintained the site lately.
