We decided to experiment with just the bent steel rod resting and rotating against a clamp.\n\ni like the jalero: it's homemade and pretty inexpensive, and uses those round things with a set screw so the distance can be adjusted; it's all stainless steel and aluminum.\n\n== Motor Area ==\n\n=== Motor Area Photos ===\n\n<gallery caption=\"Motor Gallery\">\nFile:Motor_threaded_rod_assembly.jpg | Motor threaded rod assembly.

See above.\n\nMotor support box - front - inside: This needs additional items: the inverter, etc.\n\n== Electronics ==\n\n=== Electronic Photos ===\n\n<gallery caption=\"Electronics Gallery\">\n\nFile:New sensor and jar.jpeg|New sensor and jar.\nFile:Wire entering alum rod and assy.jpg|Wire entering aluminum rod and assembly that rod passes through which connects it (the rod) to the threaded rod.\n\n</gallery>\n\n=== Electronics Drawings ===\n\n<gallery>\nFile:Conexion electrica.png|Electric connections (to motor, electronic sensor, left and right limit switches and small electric water pump)\n</gallery>\n\n=== Electronics Comments? ===\n\nHere's where to comment on the electronics area - lol!\n\nMarch 2015 - Well, it looks like the problem was one of angles. The relation between the long connecting rod and the two shorter, vertical ones which connect to the collector and motor needs to form a parallelogram. So we lowered the connection point on the motor area to make sure it was the same distance from the ground as the one that connects to the collector. Since we lowereed the connection point, we added an aluminum rod to the motor area frame and used our 7\" bolt. We now see that a 4\" bolt will probably do.\n\nFirst comment...\nWe have switched out the 6\" bolt to a 7\" one. When we were using the previous design, the assembly wouldn't bind, but now it does, so much so that it manages to bend the 1/2\" threaded rod. We are at a loss to explain what is happening here. Anyone have an idea?\n\n== Misc. ==\n\nFor additional information, please feel free to contact Fred Frazelle at info@fundacionanisa.org\n\nReturn to Home Page: [[Anisa Foundation parabolic solar hot water heater]]\n\n== References ==\n\n<references />\n\n{{Page data\n| part-of = Anisa Foundation parabolic solar hot water heater\n| keywords = solar water heater\n}}\n\n[[Category:Solar hot water]]"}
