  1. He fell backwards down a flight of concrete steps? That doesn't sound right, since he survived the incident.
  2. Barry, The photo that Strauzart linked to is fascinating. Is that what they mean by a French Polish?
  3. Ethanol precipitates water, therefore 100% ethanol is difficult to come by. I was told that Everclear is 150 proof, meaning it's 25% water, so the 75-80% ethanol would be accurate. I would imagine that Everclear has a high water content because the makers don't take many steps to keep air away from the ethanol, and so the water content builds up.
  4. Actually, the true definition of French-Polish is the following: If Witold Lutoslawski married Nadia Boulanger, their offspring would be French-Polish.
  5. Lincoln also has an orchestra. That's an important issue from both the business standpoint of demand, and also the quality of life there.
  6. Pernambuco is a tropical hardwood, like Mahogany and Rosewood, and as such the pores are very large. If the pores aren't filled, the final varnish will collapse into them, and the resulting finish will be unsatisfactory. Thus, French Polishing, using a muneca and pumice, is quite necessary when finishing with these woods, as one would do when bowmaking, as well as guitarmaking when these woods are traditionally used for sides and backs. As was stated, Maple and Spruce do not have these large pores, so pounding the wood down with pumice/oil/shellac is pointless, and may harm the sound of the instrument. I think the big problem with French Polishing violins stems from the practice of placing shellac over the original finish and then polishing the shellac to a bright shine. The practice was widespread because it was an easy way to make an old violin look new but obviously destroyed the original finish of the instrument. It's true that many modern guitarmakers fill these tropical wood pores with epoxy, then varnish over the epoxy with nitro-cellulose lacquer (usually), but a few traditionalists insist the French Polishing is the only acceptable way to varnish a classical guitar. They suggest that the sound is much better, although the finish is quite fragile and must be restored periodically. The advantage is that the varnish on a French Polished guitar can be quite easily repaired if the luthier is skilled at French Polishing.
  7. Dover publications comes through again. For five and a half bucks, buy one for a friend. "http://store.doverpublications.com/0486204251.html">Antonio Stradivari: His Life and Work
  8. "Farbizzener" isn't a dye; it's an insult. Yiddish with George and Laura
  9. quote: Originally posted by: Darren Molnar I wonder if the most appropriate material would be the lightest form of calcium based something. What about diatomaceous earth?
  10. I should mention that describing their maple as "superbly flamed" is hyperbolic, at best. Craig - at those margins, why take another photo?
  11. I've gotten a couple of these; they're not too bad: Cyber City Software violin-in-the-white They did have ebony fingerboards, nuts and saddles. Some of these have black painted fingerboards.
  12. Actually, the story I was referring to is the following: back in the 1960's, while the LA Philharmonic was on tour in Italy, one of the violinists found a nice unidentified old Italian violin in a violin shop and bought it. Later, in London on the same tour, he took it into a shop there for a small repair and was told that he had purchased a Strad. I don't remember the fellow's name, but I could probably dredge it up if anyone wanted to know it.
  13. I've been told, by fairly reliable sources, that there have been previously unidentified Strads that were identified as such by experts. Prior to that I was of the opinion that only inauthenticity could be proven 100%, but not authenticity. I would be willing to bet that there are experts who post here, Jeffrey in particular, who could make that kind of an identification under those same circumstances.

  15. You can use alizarin tube paint in varnish, whether you've cooked it or not. You can also use tube paint made from madder lake, but these are hard to find. Alizarin tube paint is made from synthetically made alizarin. Grinding (mulling, they call it) madder lake or synthetic alizarin in linseed oil yields the same substance as the paint you get in a tube (if it's very high quality paint; lower quality stuff has other additives in it).
  16. I'm a little bit confused here. Is there a reason that this French recipe for extracting madder lake a la Perego can't be posted? Is there no link to any instructions? Are they too long and detailed for a maestronet posting? The photo essay is very interesting, but appears to be a little bit to unspecific to follow as instructions for this procedure. What am I missing here?

  18. I'm sensing a degree of difference of opinion among the posters here. Edi - when you are acquiring broken hacksaw blades from steel merchants, are you able to ascertain whether those blades are solid HSS or bimetal? It would seem that, if bimetal blades are used, they would be the ones to break first.
  19. quote: Originally posted by: David Tseng I use iron acetate. You can prepare it this way: go to food store to buy pure 5% vinegar, put in steel wool (make sure it's not stainless) small amount at a time, keep the cap on but not tight so the H2 gas can escape while keep O2 out. Do it in well ventilated area so H2 gas will not accumulate. When the reaction stops, about 2 days. The solution is ready. Keep the cap tightly closed, oxygen would spoil it. Use 2 panes of window glass or plexiglass to make a narrow tub so you won't waste too much solutions. Soak verneers in tannic solution (the concentration is not critical) for a day or 2. Rinse well. Soak in iron acetate solution for a day or two. Rinse again. Let it air dry. Do as many as possible because the acetate cannot be kept too long. the black veneer can be kept indefinitely for later use. Iron tannate is very stable and is jet black, it will not stain the surrounding wood. David, Maybe a small piece of eqipment from beermaking will help you out. This airlock, placed over your vinegar bottle, will allow the H2 to escape without allowing any oxygen to enter: Airlock
  20. You can go to your local hardware store and buy a can of Bulls Eye Amber Shellac, and apply about six coats to the violin, and polish it a bit after it's dry. The Amber color is a nice golden yellow, it's very easy to apply, and it dries very quickly. This will be a very satisfactory finish for your son's violin. If you want a nicer, more professional finish, you could apply a few coats of diluted amber shellac (dilute it with de-natured alcohol), and then varnish it with a varnish available from one of the retailers I've linked to below, or do a search here for Michael Darnton's Mastic Varnish if you'd like to make your own (it's really very easy, although it takes a couple of weeks to dissolve the mastic). The shellac provides a very good ground for the varnish, and clear or colored varnish looks very good over the nice amber color.

  21. quote: Originally posted by: Michael Darnton All I will say about this is that when you read an article or a study (I'm not talking about people on this thread, as far as I know) on anything in the media, it's always a good thing to do a little tracking to see who the person who wrote it or is quoted is paid by and working for, and what position their bias is on. Now, with the web, this is an easy thing to do, and, I think, obligatory. One thing is for sure, and that is that you can't count on journalists to do this for you. In the global warming issue this is almost always particularly interesting and revealing. Do that research, and some things become VERY clear about global warming. If you haven't done that tiny bit of backgrounding, it's best not to speak about it, I think. In the spirit of staying on this topic, and avoiding rancorous thoughts, I won't comment beyond that. T-5 Do you mean, for example, an article written by a corporate shill for a reactionary publication, in which he makes reference to an article written by himself?
  22. At least he admires your work: "Perfect Master Carved Scroll" If your photos can sell his cellos, they ought to sell yours.
