Q:pedal steel guitar...?
Pedal steel guitars are a challenge to learn but they're a great instrument. More, even a starter pedal steel is going to run you $800 or so. Elderly Instruments in Lansing, Michigan sells a Carter brand starter pedal steel for $795 which is about as low as I've seen new ones. It has 3 foot pedals and 4 knee levers so it's nicely equipped. From northern Indiana it's not that far I would think. Good luck.
Q:Ways to damage steel?
Your best bet would be a grinding wheel attached to a small electric motor. Even if you slipped, your skin is too soft to be cut by the dull wheel. Steel, however, is easily cut. But perhaps you don't have access to electricity or pressurized air to run such a tool. In that case, a simple file would work well, though you'd be somewhat more likely to injure yourself. If you had no tools, but access to whatever chemicals you wanted, you could try a weak acid. This would take a long time, and require constant scrubbing to bring fresh acid into the pits in the metal, but it would eventually eat through the collar.
Q:Probability of steel hardness?
Suppose that the hardness of steel is uniformly distributed, taking on values between 50 and 80 on the Rockwell B scale. That would be... f(x) = 1/(80 - 50), 50 ≤ x ≤ 80 . . . . . 0 elsewhere Consider this following problem.. Compute the probability that the hardness of a randomly selected steel specimen is less than 60. Here, we have... P(x 60) Oh! Know that the mean and the standard deviation of the uniform distribution function are... µ = (a + b)/2 σ = (a - b)²/12 You should get... µ = 65 σ = 75 Now... P(z (60 - 65)/75) = P(z -0.07) Hence, you should get around 0.462. Good luck!
Q:TRAGUS PIERCINg?!Stainless Steel?!?
It seems like less people are allergic to titanium than surgical grade steel.
Q:Thermal expansion of steel?
It seems you are trying to convert celsius to Fahrenheit, Why? There is no need. Delta L= alpha (initial length) (delta celcius) what you need is an alpha, it should be given in degrees celsius to the negative first (steel's alpha happens to be 0.000036 1/celsius). You also need the length of the beam at 35 degrees C. This answer (delta L) needs to be added (if heat is rising) or subtracted (if heat is dropping) to the original length.
Q:Best Quality Steel...............!!?
In steel construction there are many standard types of steel used. Lots of different factors contribute to your steel choice. How tall is the building? Are you in an earthquake zone? Steel for the columns, or the beams? You might want to refer to the American Institute of Steel Construction for more information, they are the governing body in the US.
Q:Does steel have a valence?
Steel is a mixture, so it doesn't have any valence number. On the other hand, all of the components of the steel mixture are in their elemental forms, so all the various valences are zero.
Q:What is the best steel to use for making a knife?
O-1 is an excellent steel. If you've never made a knife before find an old file and use it. My first knives weren't that good, it took a little practice to get the geometry right so be prepared to burn some steel. The advantage of a file is it is already hardened, unless you have a torch or forge that will be near imposable for you to do. The most important thing in knife making is the heat treating. The best steel wont perform like it's supposed to. If you decide to use a file grind your blade out, keep the steel cool; do not let it get any color in it (brown, blue, purple) as this destroys the temper. When your finished put the blade in the oven at 400 deg for an hour. It should have a good hardness for a knife then. As for me, I use old car springs(5160), saw blades(L-6) for many of my blades, Good luck.
Q:How to temper steel? ?
Heat treating easy, HA! It is the most critical part of bladesmithing. Done wrong and all those hours of work go up in smoke (or a snap of the steel). You'll need a bucket of oil, preferably one that is deep enough to go in point first. If not you'll have to go in edge first, not recommended on a double edged blade, ok for single edge. You'll need to build a charcoal fire long enough for the blade. You will need to blow air under the fire to get it hot enough, the challenge is getting the heat even. You get the fire going and established, put the blade in turning it back and forth (if you keep turning it in the same direction when it heats up you could work a twist in it). When it starts turning red pull it out and touch it with a magnet, if the magnet sticks put it back. Keep heating and repeating until the magnet no longer sticks. Heat a little more, then quench rapidly point first. Don't let the blade lean to one side as warpage will occur. When it cools enough to touch, check with a file. If the doesn't file cut then you've properly hardened the steel and it's ready for temper. Now comes the really hard part. Grind the scale off carefully,preferably with a side grinder with a flap wheel. I've had hard wheel break freshly hardened blades. After cleaning you'll need to put it in an oven (preferred) or use a torch and carefully heat the blade. Watch the temper colors (oven temp 500-550F) or with the torch as the steel turns colors blue to purple for a double edged weapon. Any warpage that occurs needs to be worked out at temping temp.
Q:Steel or Nylon strings for my guitar?
Musical style speaks volumes when it comes to this issue. Those who want high volume will be unhappy with unamplified nylon string guitars. From my perspective, the basic difference between steel and nylon is this: steel strings ring and nylon strings resonate. The volume produced by steel is generally much greater than nylon but, to my way of thinking, the sound resonance produced by the wood of your guitar is largely masked by steel strings. If you have a decently made guitar (generally, around a thousand dollars and up), the sound interplay between the wood and the strings in a nylon guitar is magical across the entire frequency range. With a steel string guitar, the sound produced by the vibrating string overpowers the wood resonance at all but low frequencies. Personally, I'll take a nylon string guitar any day for the sensitivity gained from the interplay between wood and vibrating string.
