comment How do I “fix” a bad sweat (solder) joint?
Agree with using MAPP. Also, the joints need to be cleaned well.. and your flux (and brush) should be clean too (eg. it's pointless to clean everything and then use a dirty brush and/or dirty flux). The fitting should be hot enough that when you touch the solder to the joint, it "sucks" it in and basically goes all the way around (sometimes you have to touch it to the opposite side to ensure it's all sealed). If you have water in the joint, this won't happen, and you won't get a good joint.

comment How to build a screen canvas?
Many projection screens (like this one, for example), are mounted to the ceiling, and can be pulled down (some manually, some motorized) when needed, and otherwise stay out of the way. I'm asking if that's your intent, or if you would want to build something portable, or if you'd build some kind of temporary structure with a screen on it that blocks your windows all the time, but can be disassembled/moved when you move out.

comment How to build a screen canvas?
You mention the wall has huge windows -- does that mean you're trying to build a screen that retracts? Do you have something in mind for that mechanism already?

comment What would cause a gas fired, forced water boiler to shut down?
Have you tried cleaning the flame sensor (using steel wool, or fine sandpaper)? This normally needs to be done yearly. The gas not kicking on at the right time sounds like a totally different problem, but cleaning the flame sensor is easy and cheap and will at the least rule it out.

comment How do I stretch a replacement drain hose to fit over the existing pipe?
What sort of hose or what's this for? Why is the new hose different from the old? Pictures may help

comment Is there an easy way to measure the height of a tree?
@JohnFx - agreed, if you are on flat ground with the tree. If you are on a hill, with the base of the tree below you, this method still works.

comment How can I troubleshoot a ceiling fan light kit Issue?
Is it a single bulb? If multiple, do they all flicker together? Is the bulb a CFL or incandescent, or something else? Have you tried replacing the bulb with another one? How about with another type (brand/technology) of bulb?

comment Can I replace Velux flexible tubes with rigid after installation?
Are you sure rigid vs flexible is the problem, and not the fact that you're making 90 and 120 degree turns? It seems to me like a single straight pipe is going to be the most efficient, while as soon as you start doing turns you're talking about light having to reflect off multiple surfaces to make it to the fixture inside, which means a lot of light will not make it there. Seems like a lot of wasted money to replace the tubes and possibly still end up with the same result..

comment How can I keep an entry gate operating during a power outage?
There's several factors that you need to take into account in addition to this. The startup draw of a motor is generally 6-7 times the full load draw, which means you need a much higher rated UPS just to handle the startup. Many UPSes, especially cheaper ones, put out a modified square wave (instead of a true sine wave) and this may not work or may even damage the motor.

comment How can I keep an entry gate operating during a power outage?
What type of gate (sliding, swing)? A quick search shows that battery backup is basically a standard feature on new gate motors - it may be cheaper/simpler just to buy a new motor rather than try to rig something up to what you have now.
