  1. Cello corner template

    Bravo! Curious to learn the rest of the story.
  2. Order of operations for decorated strads

    Hi Bill, I don't think it's known. But in my opinion, the existence of the various templates, etc related to the decorated instruments (kept at the Museo del Violino in Cremona) is strong evidence that it at least happened in the Stradivari workshop. And the dates of most of the instruments being so early makes it more likely that Antonio did it himself? Though we do know he didn't invent the technique, there are a few Nicolo Amati violins with similar decorations made about 25 years earlier. I think you will find this article interesting:
  3. Order of operations for decorated strads

    Hi Bruce, Thanks for that information, it makes a lot of sense. My ivory comment was just repeating what I read in Thone's Stradivari Vol III. Though truthfully I do see variation between some instruments, for instance, to my eye the Cipriani Potter's lozenges are a lot more uniform in color than the Rode's, especially when viewed head-on. As a result there is more twinkle in the Rode. But perhaps that's a result of varying absorption as you described, and not the type of ivory.
  4. Equestrium harvest

    Equisetum cuts the wood fibers, like a scraper or plane does, and works unidirectionally; the debris from equisetum is shavings. Sandpaper doesn't cut, it scratches, scuffs and compresses; the debris from sandpaper is dust that can fill your pores.
  5. Order of operations for decorated strads

    I have studied three of the decorated Strads up close, though most of what I know about them comes from the book Antonio Stradivari - L'Estetica Sublime by Gary Sturm (•antonio-stradivari-lestetica-sublime/) If you're planning to build a decorated instrument it would be a very helpful resource. Some of this has already been stated, but - on most of the instruments, the decorations on the ribs and pegbox are carved with a knife & gouge and filled w/ a black substance. The carving of the ribs is done while the rib stock is still flat, they are then bent, then filled (before any ground or varnish), and then abraded to remove excess filler. I don't think there is full consensus on the black filler, but a more recent study done on the 'Gruffuhle' violin shows it to be a "resinous shellac". There are also a few with the rib and pegbox embellishments simply painted over the ground layer and then varnished over, no carving. One random aspect of the decorated Strads I always found interesting... on some of them, the inlayed ivory pieces on the top and back plates alternate between Indian elephant ivory for the circular dots (having a yellow hue) and African elephant ivory for the trapezoids (whiter in appearance).
  6. The Chi Mei Collection Book from the Cremona Exhibition

    Here's the list. Also it's strange they got the count wrong, there are 22 instruments/makers featured in the book - 19 violins, 2 violas and 1 cello.
  7. High tech vioiin idea

    So if I'm not mistaken, this instrument would remain acoustic? And not require amplification to showcase the synthesized tones? Also can you elaborate on the concept of "injecting sound into the bridge"? And how this "injection" would not "leak" into other areas of the violin?
  8. Nut v. Bridge

    I think this is spot on. Though I was mostly referring to the blaming of the nut yet omitting (and forgetting why?) the top was removed, misleading wording about K. Jacobs and Chi God, and mention of Machold as viable in 2017. All together make for a bizarre and confusing read.
  9. Nut v. Bridge

    This has to be one of the most bizarre and confusing threads in recent MN history
  10. Is this ground acceptable?

    Certainly not -all- of them have been french polished. But a lot, sure.

  12. Scoop on baroque fingerboards?

    I would recommend planing scoop into the core of the fingerboard, when you glue the veneer it will conform to this shape.
  13. Stradivari Medici Tenor Most Original?

    Dwight yes I think you're correct. Alessandra Barabaschi says "the neck, fingerboard, tailpiece, tailnut and bridge are all original, while the monogram ‘ASC’ is stamped in the mortise of the pegbox". ( The link you posted quotes Beare saying pegs and endbutton are original too. Outside of bowed instruments, the "Cutler-Challen" mandolino of 1680 is almost perfectly preserved (save for pegs I think?) and even has the original case.
  14. 1735 'Chardon' Del Gesu Guarneri Photos

    This instrument is featured in the book Cremona 1730-1750: nell'Olimpo della liuteria, edited by Christopher Reuning; including standard pictures and measurements. It's a great book and decently priced. A front view (only) is in the book The Schambach-Kaston Collection of Musical Instruments, published by Yale University, where it used to reside. There are also some pictures on the website of the Osaka College of Music, where it currently resides. Though the pictures are not great and the site is a bit difficult to navigate. Coincidentally, I am about to varnish a copy of this instrument (and there are some pictures on my website (linked in profile)).
  15. Carl Becker sr how many instruments ?

    Tarisio's Cozio Archive says "His production was quite extensive, totaling 414 violins, 17 violas, and 63 cellos before 1948, at which point he began to work jointly with his son." ( Also, I have in my notes from a history lecture given at CSVM, that Carl Sr's first violin was built in 1901 and by 1923 he had built 100 violins. This was while working for Lyon & Healy and Hornsteiner. And of course the Becker shop is still open in Chicago, you could probably get an answer directly from them -
