As a student what strategies & techniques you use in information retrieval on the internet?
I'll bet when its flashing it means it hasn't reached that setting yet. Dang- you keep it above 9? Thats too hot.
The first answer is really good, this is just a note on why the coil is a really bad idea. Lightning has a lot of high voltage and has an alternating current part since it's high frequency noise although the main current is direct current, that's why it's dangerous. If you put a coil in there these resist the current flow due to the high frequency noise so will heat up the wire far more than a straight wire. In the case of lightning this will likely mean it'll melt, breaking the circuit to ground so the lightning will jump to something else that conducts better.
Hello there, You can use any electric drill for that purpose. The problem with most electric drills is that the jaws of the chuck do not close small enough for the small diamond drill bits you must use. You can buy a special chuck to replace the chuck on your drill. I have one equipped in that manner that I keep in a drill press. For small hand work I use either a Dremel tool or a flexible arm. The chucks on those are designed to handle the small drill bits. For metal, resin and probably glass you will not need a diamond drill bit (good thing because those get pricey and break easy). For the stones that may vary depending on their hardness. The crystalline stones, like rubies, will need a diamond bit. Softer stones like agate you can use a carborundum bit. For the softest stones, like turquoise, you can use metal bits on them. Also, it is a wise idea to keep the drill bit lubricated to reduce the heating. They make a special lube for that, also used with diamond blade saws, but for most operations water works to keep things cool enough. I assume you are a hobbyist wanting to do some bead work. I would suggest going to a hardware store (like Lowes) and buying a Dremel tool and a few small metal bits. That will work for most of what you will be doing. Later,
