Some other helpful hints (not from Heloise) 0) ALWAYS wear gloves and eye protection. (Note: if you're using one hand to hold down the material being drilled, a glove can reduce injury if the drill bit jams. On the other hand, you should never depend on body parts to hold things in place) 1) When drilling into soft material such as plastic or pine, ...

I know it's in the comments, but I feel it's important enough to place in an answer: Never EVER throw water on a fire that is , or might be, oil or gasoline - based! If your furnace does not have an automatic thermal cutoff valve on the fuel line inlet, you're out of code (at least in Massachusetts), and should definitely have a plumber install one. Keep ...

Just some things I see on jobs all the time: Do not use a power drill (you want to keep mix things). You will blow out the motor in a good power drill by using it as a mixer. I see my guys use their Makitas with a mixing rod. And have seen many ruin them. I simply give them a 30 year old craftsman electric drill I have that I would give away for $5. ...

Radial loads are bad. Axial loads are good. The bearings in your drill or drill press are designed to counteract the forces in line with the drill bit. A milling machine does both, and using a drill or drill press like a milling machine will destroy the bearings quickly.

If you're drilling metal, use an appropriate type of bit (HSS, whatever), use some cutting lube, and drill for short periods with breaks between. Don't run the drill too fast either. If the bit overheats you'll ruin the temper and destroy the bit. Since the title of this question really should be "tell us the dumb ways you broke stuff", I'll mention that I'...

If you put a hole saw onto your drill, avoid going fast and always brace it well in case it catches. I have a bad wrist to show for careless hole saw use.

From reading all that you wrote, including the update, it is clear that there is an oil leak somewhere in the furnace mechanism or in the fuel line leading up to the furnace. You should continue to keep the furnace off until you can get an oil furnace repair professional in to take a detailed look at what has gone wrong and get it fixed properly. You will ...

a drill bit is not designed to cut on the flute like an end mill. However you will see many folks making a hole larger by moving the drill off axis. It works but not clean. The biggest advice I Could give is to use cutting oil and slower speeds when cutting metal the goal would be to have a long chip develop this shows your speed and pressure are correct for ...

It depends on how much you want to spend, how old your water heater is and what kind of water you have. The aluminum rods are usually the cheapest followed by magnesium. The combination rods I don't have much faith in as the least noble metal is eaten away first. powered rods that will last a lifetime are very expensive due to the platinum wire used. Your ...

One problem (and not just with home cheapo) is that there are many models of toilet that all do the same thing, with somewhat different and not always compatible parts. Some have 2" flush valves, some have 3" flush valves - etc. Two problems with home cheapo and lowes and other things like them is that the help are often not particularly knowledgeable, and ...

As long as you purge the tank until the moisture out you should be fine. I maintain some big compressors 150-200 hp that all push up into a separator tank to make sure any oil is removed from the water then the oil drains back to the compressor and this is a commercial setup. I am guessing you have a manual valve, when there is very little water vapor coming ...
