  1. Currently you will wait two years or more for a Bellini. Recently I tried a three day old unplayed violin by Bellini. It was an awesome instrument considering it was unplayed. He takes his time and is very meticulous. A word of caution about your maker assessments. No one can make instruments that sound the same. Granted some are more consistent than others but...
  2. Yes. And the lack of minerals on the top would explain that they needed to fill the more porous maple and not the spruce. I wonder if top samples showed mineral/filler from other studies? And is the particulate matter merely visual and accidentally acoustic or only visual?
  3. I am with you on this one. I highly doubt that they spent lots of time and energy with varnish outside the conventions of the time. If anything, they took existing methods and tweaked as they saw fit. It occurs to me that the mineral content that we find (that is sometimes missing depending on the sample studied) could be a means of smoothing after scraping. Remnants of the sanding material are what MAY constitute their presence. I know that some of you will get hot and bothered that Strad and others ONLY used scrapers. Or if you believe Sacconi and others used horsetail or fish skin post scraping. Perhaps there may have been another method...
  4. Depending on the sample(s) used there seems to be some inconsistencies in the various studies. The recent strad article did point out basic agreement between the three systems outlined.
  5. I would think the opposite would be more effective.
  6. I was just rereading some of the Curtain/Alf stuff about their approach. They mention fuming with ammonia for 15-20 min. I have the Condax research somewhere. I am going to dig it up.
  7. Sergio Peresson was an interesting maker. Much sought after in the 70s and 80s. His fame was secured when Jacqueline DuPre used one of his cellos. Eugene Fodor was another proponent. Many of the Philadelphia Orchestra members at least at one time used his instruments. The better instruments have good volume and projection. In model and approach he evolved into a maker that took a left turn. Worked for Moennig. Some became critical of him after the demand went up. His fiddles go for a decent amount.
  8. On a less than scientific hunch, I feel that there is something to the acoustic properties of the sealer (the first contact with the wood). Not only the composition but the method of application. I have found that Sacconi's, Peresson's and Zigs clues reguarding this to be thought provoking.
  9. Potassium silicate has a ph of 11.3. At least this was from an online source. Not sure of the concentration. I had heard that the alkaline nature of waterglass is bad for the wood over the long term. As pointed out above it is hydroscopic. But then again so is wood... Did the cremonese have access to potassium silicate?
  10. Read most of the blog posts about the viola and cello. Some interesting points about violin making. Pretty well written too. I enjoy his preferance/exploration of poplar and willow vs the maple dominance. He also does not shy away from slab cut backs/sides.
  11. I can respect this. It is for this very reason that I am leary of posting information from a visit that I had with Luiz Bellini. Out of respect for him I need to ask before I post. It is fair to say that he is not bad with antiquing
  12. Could you share some details about Becker's system?
  13. You guys need to keep in mind that Don was part of the team thay designed the Mars rovers that the original spec was for 90 sols (Martian days). The Opportunity rover has lasted 2737 sols. That is off the charts "over engineering". That gets my deep respect and could be beyond the scope of most fiddle engineering. Remember the shuttle tiles?
  14. Clearly Strad would prefer Illustrator (vector) and del Gesu Photoshop (raster).
  15. I used to use unwound gut strings (Heifetz influence pre Baroque Renaissance). I found that they did not last too long in general. I didd not want to store them very long. Hydroscopic and prone to oxidation perhaps.
  16. Any synthetic core string should be fine. The silver wound strings will tarnish if stored for a long time. No biggy though.
  17. I have tried most if not all of the available strings. With certain exceptions I stick with dominants. Tonicas are good but not quite as good as dominants...in my opinion. I might be picky though. Cello A and D and viola A are a different story.
  18. Strings that are not being played would have a longer life than those that are being constantly played. Strings under tension will very slowly degrade over time.
  19. I would describe the sound of strings that need to be replaced as dull and less reponsive than they need to be. When you put dominants on they are buzzy and metallic. Dependiing on how much playing you are doing, you need a minimum of four days and as much as a week for them to settle in. If the instrument is not being played it may take more time. This is provided that the instrument is not very dark to start with. After strings have been played out they lose the overtones and the small amount of sizzle that is desirable. It feels like you have to be more aggressive to get the sound you want vs the sound being there.
  20. Ditto on Szeryng and Kreisler!
  21. I used to be an admin of a very active board. We used a different software (vBulletin) and had some problems with the search. It was better than here at MN but only a bit. The indexing was an absolute pig with resources though. We scheduled it for the wee hours of the morning. Fond memories...The board software is not bad othewise here at MN. Someone should sticky to use google to search.
  22. How does 20K...ish strike you? Good luck.
  23. We have one of these at the school where I teach. I have seen some pretty cool stuff that they have achieved. Most of the pieces have been relatively small scale (6-8 in.)
  24. Starker has not had the Strad for many years. When I was at Indiana in the early 80s he was playing the Gofriller. The Aylesford is a large instrument and Starker did not like playing it for that reason. His Gofriller is gorgeous.
