Setup Weekend.
Ok, still a few things to fix up and such, but a lot of progress and pictures...
The canopy lift system first. I haven't got to the video yet. I took some, but haven't gotten it uploaded yet. Maybe tomorrow.
The lift is constructed as follows:
- 3" U-channel steel frame that supports the lifted canopy.
- 1" steel linear rails (50" long). (Made for CNC machines)
- 1 36" linear actuator. Rated at 400lbs & about 0.6"/sec travel.
- Entire assembly is powder coated to protect it from rust.
- All bolts are stainless steel to prevent corrosion
The actual lift operation occurs as follows:
- Steel frame rests on steel supports bolted to the back of the stand. No weight of the frame rests on the glass! (about 140lbs for the frame).
- Actuator slides in a steel tube attached to the frame. A bolt allows for adjustment of where contact is made. This allows adjustment in range of travel and back off to allow the frame to rest on the steel supports rather than the glass.
- As the actuator moves up it eventually makes contact with the frame (about 4"), then starts pushing the frame up.
- The frame has arms that go into the back of the canopy. These are also backed off from the canopy so the canopy 'floats'. There are (4) levels bolts (stainless steel) that control when contact is made.
- As the frame goes up, it eventually contacts the canopy and lifts it up.
- The actuator has built in stops that shut off the motor to prevent it from going beyond it's normal travel in either direction.
This is the back of the lift system mounted to the stand:
With the canopy lifted in full up position (about 26 - 30"):
This is the inside of the canopy on one end. The canopy has a steel frame that acts to strengthen the walnut skin, hold the light fixture, and attach to the lift system.
Ok, everything is nice and level, so time to fill her up...
Rock work was pretty typical. I was trying to get a few specific effects, but I wasn't thrilled with my results. In this one, I was trying to get some "branches" that gave an appearance that they were 'floating'. Similar to the 'bonsai' thread if you've seen it.
Here I was trying to get a tall structure that would actually go out of the water every so slightly. I've seen some threads that did this and it seemed to give an appearance that you were 'under' the water with the reef. Not exactly great execution, but might adjust it down the line.
Halide light cords were too short! Going to have to get some extensions soon, but for now with just the actinics.
It definitely make a presence in the room, but I think "management" is going to get used to it.
