comment Where can I find strong magnetic strips?
This seems like a "let's go shopping" question. You might want to review this post about 'shop for me' questions and see if you can reword it. A quick google search yields lots of hits for strong magnets. You'll need to explain why the google results are inadequate for you question to be accepted.

comment What could be causing this washer to rattle very loud sometimes?
It's not really clear from your question what, exactly, the symptom is. Is it the predominant high frequency sound in the video? If so, I'm not confident that I'm hearing an earnest reproduction of it which makes it difficult to offer second opinion. Or, is it the amount or nature of motion of the basin you are concerned about?

comment How can I reduce the noise from a bathroom fan?
+1 just replace it. Good mounting of a vibrating fan might lessen the noise, but the only proper solution is to eliminate the vibration in the first place. Good fans don't vibrate - they may make audible white noise, but they don't vibrate.

comment Will I see any performance gains if I reconfigure my thermostat to control the second stage of my 2 stage furnace?
This is a good answer. In my suite, the thermostats are set back to about 50F when we leave (there's an automation interlock with the intrusion detection system). When someone arrives back home, the HVAC controller calls for both stages of heat. This heats the suite at about 9F for every 7 minutes. With only one stage, it takes about 4x as long. So, with two stages of heat we can allow the temperature when unoccupied to drop further, thereby reducing waste heat while absent, and still return to a comfortable temperature in the same amount of time when you get home.

comment What are the proper materials and method to hang heavy-duty shelves in a garage for storage?
@oscillatingcretin I've had luck with specialty heavy duty casters at mcmaster.com. I just retired three of the same shelves as your pictures with swivel casters. You might want to consider that casters increase the risk of toppling significantly for two reasons (1) the offset design common to most casters can move the contact point with the floor closer to the center of gravity, and (2) rolling means that you now have a live load whose center of gravity is much higher than a braking force that would typically be applied at the bottom of the shelf (think caster running into a stick).

comment Why is the first shower of the day is colder than the second?
+1 for digging up the manual and suggesting over temp + mixing valve.

comment How can I center a drill bit so that it drills absolutely straight down rather than perhaps a little off to the side?
Are you pilot drilling first? Whether or not you use a guide, a drill press, or freehand, pilot drilling will result in more precise starting position and path of the hole. Even CNC machines are usually programmed to pilot drill holes beyond a certain depth and usually center drill all holes before running the final bit through.

comment How can I add a “C” wire to my thermostat?
Couldn't you repurpose one of the existing conductors to be common then "add-a-wire" to replace that conductor?

comment Is there a technique to make a shower mirror fog-free?
@sharptooth - That's not the heart of my claim at all. Rather, my claim is that water heaters have a metal chassis in contact with water in close proximity to the electric heating element that is meant to provide a good path to ground in case of failure. And that in a normal installation where the chassis is grounded a la electrical code, that grounding is the primary means of electrocution prevention. And that similar electrocution prevention by grounding is not possible for a heated mirror because there is no chassis to ground.

@sharptooth - Good point about plumbing not necessarily being grounded. But are you saying that the tanks/drums of water heaters aren't grounded either?

comment Is there a technique to make a shower mirror fog-free?
@sharptooth - We needn't worry about electric water heaters because the drum of the water heater and the plumbing has a good path to ground. You cannot say the same about a mirror in a shower - the human could easily be the best path to ground. I'm not saying that the mirror heaters are dangerous, I'm just saying it's not apples-to-apples wrt electrocution risk.

comment Is it cost effective to close some heating vents?
In that case, I'm fairly confident that closing vents and doors to unused areas will reduce the cost to maintain the used areas at a comfortable temperature.

Is the return air vent in the storage room the only one? If so, it may actually be better to leave the door open, otherwise the furnace might find a much colder source of make-up air.
