  1. Amazing situation. Reminds me of a National Geographic essay I saw once, where lions were eventually driven away from their food by hyenas. Probably insulting to the hyenas, I suppose, but that's what comes to mind. Maybe I'll take a break...
  2. I think all the members of the Rosewood family (I'm not a botanist--maybe "family" is not the right word) tend to be allergenic. My first major reaction to wood dust was when I made my first instrument. I used Brazilian Rosewood for the fingerboard, and made it from scratch, so there was a lot of shaping, and, as I used a drum-sander to hollow the underside (first try--didn't have proper gouges) I breathed a lot of rosewood dust. I enjoyed the smell...poor fool that I was. By that evening or the next day, I was having a MAJOR allergic reaction, sneezing incessantly; and it lasted for severa
  3. "Does anybody know the principle of these kids' cards with a real depth effect?" If you are referring to the ones with tiny grooves on the surface, it is a modification of the Fresnel lens (q.v.). I have one that is clear, exactly as thick as a credit card, but magnifies like a large glass lens.
  4. "How about a contest for tonal discrimination with prize money? " How would you go about adjudication? No one even agrees about what they hear, and all insist they hear better than the machines...
  5. The problem is not that those foods are defective, it is just that they just are "not as healthy as other foods". Would you rather your computer (or TV...pick your poison) shut down every 45 minutes, with the requirement that you go do some calesthenics, and read a good book in between uses? Or some other thing? Maybe require that all TV sets and computers run only on pedal power, so we don't continue to become couch potatos? The problem is human nature and our tendency toward least I think that is probably the case. I have never had a deep fried twinkie, though I have heard th
  6. Whole bridge looks pretty thick...maybe just my eyes. What is the thickness at the feet, and in the center? Not saying that thinning the bridge will fix the tone. Just observing, and wondering.
  7. Well, I have seen some violas reminiscent of that shape, that had great tone. Does that violin, by chance, sound viola-ish? My first several violins were frequently accused of sounding like a viola. But in my case, the arching was at fault. For future reference, you might try emulating some particular well-known instrument, knowing that, since the original was a great violin, you probably can't go too far afield by attempting at least a "inspired by", if not a "copy of" that original. OTOH, there is nothing wrong with coming up with your own design. It just may invite criticism that you ma
  8. Yes, Walter! You have been warned! This is an addictive craft, and "no one can build just one" (with apologies to Frito-Lay & Co.). Nice work, for as little input as it seems you had from others. Much better than my first. I will look forward to seeing what you do in future iterations. Welcome aboard. Hope you enjoy the ride. Chet Bishop
  9. I only meant that Michael's diatribe against water was a joke. The EEU's position is laughable, but unfortunately real.
  10. Lyndon; Just for the record, I haven't voted, nor will I. I have only played two old master instruments (those belonging to Dr. Sloane), and, quite honestly, tapping did not occur to me. Playing and looking were all I had in mind. And, were I to have another go at them, I would take about a hundred photos, carefully showing the arching and details, the spend some time playing again. So that takes care of the first three options. I will not take the fourth option, either, because, far from wanting to ignore you or tune you out, I would simply rather you "play nice"--knock off all the ins
  11. Yep! just some silliness in response to officialdom's idiocy...goes right along with the DHMO spoof. But the ruling was not a joke...those who made the rule are.
  12. I went about as far as you, and began hoping to sell (actually, my fourth instrument, a 420mm viola, was my first sale), but to date have made sixteen, and have six violins, four violas and a cello cluttering my space. One viola was given away, two were sold; one violin and the bass were sold. I have six more on the bench (four violas, one violin and a five-string fiddle), so something has got to change.
  13. Carl, I'd like to hear what you come up with. What I have managed to glean, from conversations with old makers, younger makers of some repute,etc is that after wood quality, a close second may be arching. Obviously everything has an effect, but one thing that caught my attention some time back was someone relating how the late Bob Bein (of Bein and Fushi) used to sort through piles of violins for prospective purchase, hold each up long enough to look at the arching, and either set it aside as a reject, or set it aside for purchase. And he consistently could come up with great violins for th
  14. Here are some photos of what I have, in the condition it came...I have done nothing, so far. Maybe this will give an idea (to those who know what they are looking at) of what I have on my plate. Serial number 74108, if that helps.
  15. Thanks, Carl. I can see that I am missing the whole mountain of change gears, if indeed the machine was supposed to have had that many. I did go ahead and register on the practical machinist forum. I'm going to need all the help they can offer.
  16. 100%! You must have studied!
  17. Maybe we could develop a market for the nasty stuff, and get rid of all the wild poison oak that infests the left coast. I'd love to hear the environmentalists crying over the disappearance of that particular noxious plant.
  18. Comes from essentially the same plant, does it not? I think the essential oil in Poison Oak and Poison Ivy, et al, is urushiol, or something similar.
  19. There it is, friends! Thanks, Joshua! It had fewer of the screws than I thought I remembered, but that is good. You just want to remember they are there, and not grab indiscriminately. The screws, on the other hand, grab very well, and the cradle does not move at all. The angle is a good deal lower than I had remembered, too. But that could be whatever you decided you wanted, I s'pose.
  20. "...mountains of data, but little extra knowledge." Sounds familiar. Common experience today, it seems. I do appreciate those who seem to be able to sort through the mess of data and pick up the few gleanings that may actually change how we think about things.
  21. That's the one...I believe Evan brought them, though the fellow from Bermuda (nice gent) may have been using it. Several people experimented with it. I can't recall the name of the fellow from Bermuda...he had been a graduate of the Chimneys school, and I was especially interested to see how he fared as a luthier. Very pleasant man. Chet
  22. Sorry, what is a Norton box? I do know that this was not the better of the two lathes available about that time. The better one was a little later, and involved an addition of something...I don't know what...that made it more versatile, or something. From the photos I've seen, what I have is pretty much what it came with, somewhat worse for wear. And the metric lead screw is just so you can do metric threading? I can see where that could become important. There evidently was once printed a series of pamphlets on running a lathe, and lathe projects, all for the south bend lathe hobbyist.
  23. I think you may be right--The change gears are there, but if that "box" I was asking about is the "quick-change" box, then this lathe does not have it. In fact, I saw an online article about how to upgrade a "model C" to a "Model A". I am wondering whether that quick-change thing was the main difference. Glad to have what I have, even if I have to phyisically change gears to make it go through its paces. Once I get it assembled, and cleaned up, leveled and useable, I'm sure I will think of things I'd like to improve. Thanks, Chet
  24. Did you get my message? My lathe was working before I moved it into my shop. The motor isn't set up but it might help you to see it as it is.

  25. Nope. I was hoping Evan would speak up. It was a sturdy equilateral triangle, maybe 24"-30" square on each side, if memory serves, that could be folded flat for transport, but which was very rigid in use. The front was covered with that short-napped indoor/outdoor carpet, and the cradle had the screws penetrating it all over, so it would hang onto the carpet. (You wouldn't want to accidentally come in contact with the back of the cradle). That's about all I recall, except that the cradle had some sort of cleats that could be rotated to hold the plates.
