    Thanks for your patience.
    Rooty,

    This is the type of homework problem that we might assign to a student in "Selection of Engineering Materials" - one needs to consider the manufacturing methods, function, use, repair issues, cost, etc. Rather than pick a material, one studies the properties and characteristics of the materials available and compares those to the needs determined by the survey. Brass works.

    I have just sold all my holdings (which were 100% invested in Peruvian tinplate) and put it all on Upsidaisium futures.
    I have a title deed to a mine on the slopes of Mt. Batten. On my way there now via Peachfuzz Airlines...

    I have also just now applied for a patent on my new mouthpiece design, made of hard flubber.

    As for studying the properties etc, I am not going to do any of that as I have even less expertise than one of the students you set homework for. I just asked a question . If people want to answer and discuss it, that's great. If not, that is fine too.

    Agreed.
    If it was good enough for Ben Webster, then it has to be good enough for me.
    I note that it is always "the right time of year" to discuss metal Vs. rubber mouthpieces, and cane Vs. synthetic reeds....sadly.

    OK, to answer your question, there are many reasons to NOT select Ti - cost, commercially available forms, formability, weldability (requires special welding techniques to avoid brittle welds), etc.

    It's actually a "must have" if you plan to strap your sax to the roof of your personal SR-71 when you pilot yourself to your favorite vacation spot with the family.

    Well okay. That's one vote in favour then.

    I did appreciate the responses of Thomas and Dr G just before as well. I am still not clear why my "titanium" specs are so cheap and neat but I suppose I shall have to look into that. Alloy? No welding? Simple construction? Not actually titanium?

    Now that's another question, isn't it?

    "Yes" to all of the above. Are they actually that cheap given the amount of material in them? I don't know if yours are pure Ti. I think a lot of them are going to Ni-Ti, a shape memory alloy. Either one has superior corrosion resistance - another plus for glasses frames.

    I'm confident the answer is out there - somewhere beyond SotW.

    It is, certainly, but related, I think. You don't need to worry that I now want you to explain my glasses to me, though. I suppose it has been obvious that from the beginning I have been proceeding through somewhat questionable analogies. But to me, you see, that's ok because I really don't mind questions or even questionable questions.

    As I said, though, I do appreciate your taking the time to reply seriously and to the issue, George. When you're dealing with people without your background in science and engineering I suppose what is obvious to you may be enlightening to them.

    Voltaire's poem, La Bégueule, cites "best is the enemy of the good" - but that's not really the same, is it?

    Something can be the best yet still fall far from "perfect".

    A nice thought Doc and certainly apropos- truly- but I believe you misinterpret Voltaire's meaning in regards to the "best" in the poem. (a result of the translation from French)

    You take it as "the best available or currently in existence". I believe that Voltaire intended it as "the best" with the same intent as Socrates' (according to Plato) ideal couch from which the shadow is cast on the cave wall.
