Seriously: You just don't. Reasons: You'll never be able to guarantee you didn't contaminate the fuel unless you clean it thorougly after the work, which you cannot with all the diesel in there. That bears great (financial) risks. If you sell that stuff you might even get sued. Special drills and precautions will surely reduce that risk, but it will ...

This stuff is sick: http://www.evaporust.com/ I used it on a drill press my buddy left out on a patio in the rain for a year. Virtually no scrubbing. I don't understand how this is not one of the most widely known products in the world. It is THAT good. I guess with the military as a client, they don't need the business from the public. Here are some ...

After cutting the bolt to length, use a stationary grinder instead of a file to clean up your work. With a grinder, it's easy to square up the end of the bolt and apply the chamfer that you want. Just be careful, especially if the bolt is shorter than the grinder's table. If the bolt is short, use a pair of vice grips to hold the bolt during grinding. And ...

A knockout punch is typically capable of going through thicker metal - at the very least, it will do it faster. A quick search easily finds knock-out punches that can do 10 gauge steel, where most step bits don't seem like they'd do well beyond 16 gauge (though I can't find anything that really says the limit). For thin metal though, the step drill bit is ...

You don't want to "drill" a 1" hole in 3mm sheet. Without support the edge would be ragged and other problems would occur, such as fragments dropping into the tank. The best approach is probably to use an annular grinder. They are used for putting holes in tile and glass. Search for "diamond hole saw" on Amazon. Use a lot of water to cool it and the slowest ...

There are several online metal suppliers that will also make custom cuts. Online Metals is one that I have used. There is a minimum length that you must order (usually 1 ft) and a charge per cut. Depending on where you live you might also find a local metal supplier that can do the same for you. Wherever you order, I'd suggest you get two 5" pieces ...

I would use a punch to make a small dent in the pole so my drill bit wouldn't slip.

As Karl recommends, drilling dry with a metal drill bit (HSS or Carbide) is the basic information that you need. As far as drilling speed goes, you can refer to a cutting speed chart and do a bit of math. Aluminum's cutting speed is 350-400 fpm or 106,680-121,920 mm/minute. The distance travelled by a point on the outermost edge of the bit during one ...

You can make watertight trays from flat sheet metal without soldering or riviting. Take a sheet of metal whose length is the length of the finished tray plus two time the height of the sides; width is the width of the finished tray plus two time the height of the sides. Fold the sheet so it ends up looking like this: You can fold up one side at a ...

Based on questions answered in chat you have a case where the contractor didn't measure the deck properly, and built it too high, could not flash properly under the door frame, and performed a "some genius" move putting a transition strip (meant for interior use) over top of the door frame and the vinyl, with caulk under neath. Stupid. Two options: 1 ...

The punch suggested by SpectralGhost is a good idea. If that doesn't work, you can make a jig with three pieces of 2x4. Screw the pieces together and drill a pilot hole for the drill bit (the dotted line) using the same size bit you intend to use on the pipe.

I use CLR for that sort of thing. The main purpose in my house is for hardwater scale, which accumulates on everything, but it also works on rust. Handle with care, it is wicked strong.

Drill dry. You need a carbide tipped bit that's rated for metal; this will be obvious on the outside of the packaging. I'd drill fast.

I don't know about the machine, but depending on the size of the wire and the length, you can straighten it by holding one end in a vise and then holding the other end in a pliers and giving it a quick jerk. It takes a little practice but it works quite well. However I would hesitate to use this technique on wire you plan to use for household wiring. If ...

If you're trying to cut in place, I'd personally go with drilling an initial hole, and then cutting the shape of the vent with a "sheet metal nibbler". The nibbler will let you cut from one side, as there's a small bit that you insert into the hole, and sheers off a small roll of material (somewhere near 1/8", depending on the exact pair). You can also ...

Is the garage door made out of steel? Here is a good article on repainting rusty steel: I think the key is to prep by washing the area and then removing as much rust as possible by scraping and then using a wire brush (or even sanding). Prime the area with Rustoleum. The topcoat should be high quality latex exterior paint.

You have the basics down pat. The key to getting the threads working properly is: Squaring off the thread end of the bolt. Yes, the hacksaw blade will follow the threads slightly. If you have a bandsaw with a stock holding vise that can be squared to the blade, run a single nut on so the hexes will hold the bolt in place as straight to the blade as ...

If you can remove the entire face plate use regular paint stripper. When you get it down to bare metal you can polish the surface with scotchbrite pads or steelwool. You might find something to attach to your drill to make this part easier. Once you get the finish you are looking for cover it with clear enamal to protect it. If you can't get an acceptable ...

Based on the clarifications, I would recommend using a reusable thread-locking liquid. Here is a link to one I found that may work. I have not used it. Vibra-Tite VC3 Threadmate http://www.vibra-tite.com (I am in no way affiliated with the Vibra-Tite Company)

The bases of the stand look as if the pole is welded to it. Unless you have welding skills, cutting at the base probably will not work. The top appears to consist of a thinner pole that the speaker is attached to, inserted into a slightly larger pole that is attached to the base. In addition, there is a locking knob that seems to go through a threaded hole ...

It may be that the frame was originally designed to have slats span the rails, and not have the mattress (box spring) sit directly on the rails. This would have lifted the mattress up a bit, and possibly allowed it to ride over the bits that are giving you trouble. This was one persons solution:

User assumes all responsibility! Adding CO2 to displace the O2 sounds like a reasonable precaution. Use a knockout punch from Greenlee. Quite pricey though, do not buy a cheap one. Good up to 2.5 mm (10 gauge), meaning it's not going to like 3+mm but it will probably work once. Advantage is you only have to drill a 1/4" or 1/2" hole. This does require ...

You can use a Dremel cutoff wheel to cut off a piece of the rod but you may have to remove the rod to do this. You can use Dremel grinding wheels to grind down the end of the rod. If the rod is not protruding out of the hole, you could use a wooden plug to seal off the hole. Sand the plug flush with the bench top.

You are doing it the optimal way for somebody that just does it occaisonally. A cut that is more square across the bolt (OK - orthogonal...) can be had by using a motorized chop saw with an abrasive blade, an a grinder will help the clean-up, like Caleb says. If you were to do it this way, you don't need the nut threaded on to clean out the threads. ...

Send the city a bill for the tire, take them to small claims court if necessary, they will fix the problem.

Sledgehammer. Pound that corner down. When nobody is looking. :)

This a is a very interesting question. I must assume, hopefully not wrongly, you are talking about a main supply line from the street. I can see no reason for an in house line to be embedded in the floor unless it feeds an out building or the like. In any case, an in-house line could be tracked back to some point of source and rerouted if necessary. As for a ...

You may have a damaged/stripped bolt or threaded hole. Check to see if the threads on the bolt are damaged then you will need to purchase a new bolt. If the threads in the hole are damaged you will need to install a threaded insert or use a tap and die set.

Bread Tin Corner. How to make a water holding container without needing to solder it has been an age old necessity. You'll still see them used in cheaper bread pans, though hydroforming or stamping have taken over for the most part.
