comment How can I stop the humming produced by my water heater blower motor?
If PVC is in harmonic resonance, you can move it out of resonance by changing its mass. Taping weights to it should do the job. If fan vibration is transferring physically to the PVC, then a foam/rubber coupling should lessen the transfer. Is the fan a bearing type, or a bushing type? The former, when well maintained, tend to vibrate less.

Spray on chromic acid would do amusing things to wood or metal window casings.

comment Should the entire element on my burner on top of electric stove turn red when turned on?
There's some variation in how hot the elements get, particularly at the ends of the element and near physical support points: google.com/…

comment Should a twisted copper pipe be replaced?
Doesn't look like you twisted it hard enough to strain the metal much, so it's not likely to break on you. However, you did narrow the cross section enough to create a nasty flow restrictor. That could be a problem for you.

comment Non-sanding solution to get old pen markings out of wood?
Some pen inks are soluble in ethanol. That probably won't damage the finish.

comment LED vs. CFL Bulbs on Modified Sine Wave Inverter
That 'free' voltage conversion done by CFL's is often done with cheap power transistors and other compenents tuned for 60Hz that might not like long term use of the stepped sine wave coming out of an inverter. Relatively simple LED's are far less picky about such things. eetimes.com/document.asp?doc_id=1281325 xxx instructables.com/id/…

comment One of my glass shower doors shattered! How can I get it replaced?
tempered glass standard sizes: google.com/… If you're good with your hands you can probably do the replacement yourself. If not, go to a local glass store or a decent hardware store. The glass store'll do the repair for you, probably order the sheet as well. The hardware store will at least point you to the old guy who does this sort of work out of his basement. As you found out, a big box store is not part of the solution here.

comment How to unblock a blocked toilet?
Toilet snake'll work if you can get someone to confess to dropping a toothbrush or its like down there. Such objects can be remarkably resustant to plunging.

comment What should I do with leftover sulfuric acid from a sump pump battery backup?
I store my spare H2SO4 in its original container, inside a glass bowl at the back of a shelf in the basement. The glass'll stand up in the unlikely event of bottle failure, and the stuff does come in handy for tough cleaning problems every few years. There's no kid problem here, otherwise it'd be securely locked away.

comment How to remove glass doorknob
After a zillion years, it's possible you have some corrosion and crud buildup on the square threaded shaft. Squirt some penetrating oil into the set screw holes before torquing the knob to destruction.

comment furnace blower motor vibration when working hard
@kinar Have a look around the furnace area for the manual. Directions might even be printed on one of the removable panels. It's usually one of those manuals that someone stashes rather than tosses. Internet might even have a copy for your specific unit. Then again there might be labeled oil injection lines on the blower unit itself. I use 10w-30.

comment furnace blower motor vibration when working hard
When was the last time you lubricated the blower motor bearings? Some of them require it yearly. The info will be in your furnace manual.

comment How can I mitigate low frequency reverb in a bedroom?
Example of ceiling mounted baffle curtains here: amcraftindustrialcurtainwall.com/products/acoustic-curtains/… Hanging them 1/4 wavelength of the frequency your trying to get rid of will make them more effective. Looks like lots of good info on these and wall panel attenuaters at Google here: google.com/…
