comment Will foam-filling this gap create problems?
6" of closed-cell spray foam is a lot. From what I understand 3-4" is more typical for getting a high R value. Though the rating is ~R6-7 per inch, the pro spray foam guys I've talked to all seem to think it's effectively a much higher R value presumably because of zero air and vapour movement. I've also been told that beyond 4", it really doesn't add much (other than cost and install time -- apparently you can only spray 1-2" before letting it cure for an hour or so, then putting the next coat on).

comment How do I replace rotten Subfloor under a supporting post
What you are suggesting is dangerous -- car jacks should not be trusted as a support: it's the reason people use jack stands when working on a car. Also, -1 because your spelling/capitalization/punctuation/grammar just make my head hurt.

comment In a multi-gang box, are neutral wires paired with specific hot wires?
@drs From your picture, it looks like a single circuit switching multiple outlets/lights. The wire at the bottom of the schematic is the feed from the panel, the other four wires are going to lights/outlets. Can you just confirm there is there a single breaker that will switch off power to this entire box, and that the existing four switches control four separate sets of lights and/or outlets?

comment Can I output video single wire RCA signal out of 3 composite ports?
I don't, sorry. I have a Roku 2 box somewhere but it only has HDMI. Maybe you can use your Receiver to downscale to 480i/composite, and output that to the projector? At least you'd only have to change inputs on your reciever, not both receiver and projector (I hate having a system that requires multiple inputs on different devices to be changed).

comment Will enclosing my porch keep my house warmer?
While cellulose for walls and foam boards for basement are examples of ways of insulating those spaces, note they are not the only way. The full explanation of different ways to insulate is beyond the scope of this question (and asked already on this site) but I just wanted to point this out as this answer's wording implies there is only the one correct method. (I agree with answer in principle, just don't like the wording).

comment How can I stop the smell from my kitchen drain?
Also occurs to me that perhaps the plumbing is incorrect (either changed by your tenant, or was always wrong but just happened to never cause a problem until now). Normally there is a P-trap that holds water, which prevents smells from coming back up. Can you post a picture that shows how all the drains are connected? We can at least spot if there is something obviously wrong (eg, garbage disposal hooked up incorrectly or missing trap, etc), to rule that out if nothing else.

comment How can I stop the smell from my kitchen drain?
Have you tried a liquid drain cleaner (just be sure to get one that says it can be used with a garbage disposal)? Next step would probably be to put a snake down and see if there is something clogging it. You could also try a plumber who will snake/inspect the drain with a camera.

comment What type of room divider should I use to convert a dining room into a bed room?
When I was in university, we used a few panels of ~2.5" XPS foam to make a partition wall so a dining room could be a bedroom. Ugly as hell, but easy, functional, cheap, and actually made a good sound insulator. True story, but I don't recommend doing this unless you're under 21 and can justify it with the fact most of your money goes to tuition and beer.

comment Extra low voltage over mains voltage circuit
Aside, forgetting any potential regulatory issues, my gut feeling as I read this is whatever you're trying to do is somewhere between "won't work" and "there is a much better way". I'll reserve final judgement until you can clarify the question..
