Tell us about yourself!
To reduce the shifting from side to side, try spacing the "ceiling hooks" further apart. The ropes/threads should be further apart on top than they are near the feeder. Regarding leaks, I am not sure what you did wrong. Don't fill the feeder all the way to the top... Make sure the nectar level is below the holes level. Humingbirds have long bills and tongues capable of reaching the bottom of these feeders if the nectar level is low.

This would only work if the sun did not move.
We keep our evap. pool bleached (if you can smell the bleach, you're good). Whatever is not evaporated, we take home in 15g water drums clearly labeled gray water.
Hi Caley... I saw your FB post. Very nice!I would not worry about leveling... The playa is very leveled but you won't be able to evaporate everything to the last drop anyway. If your OCD kicks in like mine does, just play with the dirt until the water is pooling the way you want it to. This year I am thinking I will add a small channel in the dirt under the wet drum and sink in the legs as well... that way water would pool right under the drum. We'll see how inspired/tired I am once I get there. ;)
Absolutely. I used painters tape myself and it has been working still. Duct tape would be even better.
Awesome! I too modified/hybridized my design by installing a high torque motor powered by a solar panel. The motor is slow so I used a one way bearing to allow the wind to take over and spin the system faster if needed. When there is no wind, the motor takes over. No batteries so as soon as the sun is covered/set, the motor assist stops. I figured at night the evaporation is not even that much anyway so if the system is not turning, no big deal. We are camping inside AEZ (Alternative Energy Zone). If you take one of their daily tours, you most likely will see our setup. ;)
I ordered mine from JSBGreatBearingsPart number 6201-8-2RS. Not a perfect fit as far as ID is concerned (12.7mm), but close enough for this project. Search ebay or Google for that part number and you should get some results.
