  1. I usually get much clearer readings, the M2 peak is very obvious. The position of the microphone is very close to the plate and at the point of maximum amplitude of vibration of the mode and the grip of the plate at the point of greatest cleanliness of the note judged by ear. I use 4096 size, but even at 8192 the peak is really obvious. You can see the result in this video :
  2. This is interesting, could you describe how you do it? cold? hot? vapor? Although, judging from the burns that you see on ribs of some old Cremonese instruments, it looks like they used a bending iron. Do you agree?
  3. Some scans can be found in this book, which was published following studies done on the Messiah on the occasion of his miraculous apparition here in Cremona in 2016. Good cues on authenticity too. http://www.cremonabooks.com/eng/shop_dettaglio.php?id=3103
  4. Thanks Michael, in fact, given my long waiting list, my violins increase in value compared to the purchase price even before they are born. This is hard to beat as an investment value. More seriously, Cremona is still a strong brand name for violins, unfortunately too often abused
  5. The PG form is 161-102.5 - 200 mm in widths and 347 mm in length, so subtracting the thickness of ribs from your measurements it seems that you are a good 2 mm out in all sizes including the length. Maybe you started from a too enlarged image to make the template.
  6. Light, stable, easy to work, easy to bend, sufficiently compact and tought for the upper and lower blocks, as light as possible for corner blocks, and don't forget with a nice color
  7. What are the actual measures?
  8. With spruce you still have illustrious predecessors like Del Gesù, not bad at all.... I also use spruce for my rare violins based on Del Gesù forms.
  9. I agree, it is difficult to find poplar lighter than willow, although it cannot be excluded.
  10. The willow that is used for blocks and linings and that supposedly was used most frequently by Stradivari is the White Willow (Salix Alba). The reddish wood that distinguishes it makes it often confused with the Red Willow, which instead is a shrub that is not good for making blocks. Nowadays here in the Po valley it is difficult to find it pure because it is almost always hybridized with poplar, which is cultivated almost everywhere for the paper and plywood industry for many years now, with the result that the wood is different and denser. The Salix Alba that I use for my blocks and linings has a density of 0.36 g / cm3 and probably comes from Tuscany where there was no hybridization (they do not grow poplars on an industrial scale there).
  11. Did the surgeon forget some steel pliers inside when he closed the patient?
  12. Yes, that's it! Thanks Reguz for reminding
  13. I'm not a big fan of low density wood, but considering that the weight of ancient instruments is always outrageously low (unattainable?), I find it very difficult to think that they used high density wood, even if at first it had to be a little denser but not by so much.
  14. I've already seen these "spirals" somewhere, it doesn't seem like a new idea. Nice artistic compositions, however
