  1. You're welcome. There are so many ideas. Speaking of balancing, when I was in violin making school I happened to weigh my plates that I was building for a violin and discovered that they were close to a golden ratio relationship. I haven't followed up on this 'fact' but who knows there could be something to it?
  2. The best way imo is to ignore it. Instead follow sound advice.
  3. I'm also trying to wrap my head around it. I understand that the formulas are being used for various purposes, but I see it from a purely geometric perspective. I imagine that Amati, if he knew it, would also see it like that.
  4. Hi Yoshi, The Pythagorean means are three ways to decide the mean between two units a and b. The Arithmetic mean as I mentioned before AM = (a+b)/2. The geometric mean GM = √ab, the Harmonic mean HM = 2ab/(a+b).
  5. Interesting topic this. I have recently been curious about the classical three Pythagorean means; the Arithmetic, Geometric and Harmonic mean. I was thinking that they should have a relation to violin design but, unfortunately I haven't found much apart from the arithmetic mean a+b/2. That said, I have just recently begun to dip my toe into this subject of Pythagorean means.
  6. Hi, thank you. I'm buying the set. I also want to give a stick to my client as a gift because she's travelling a lot. Should I get #2? Pegs are well fitted.
  7. Hi duane88, is this that? https://www.ebay.com/itm/191702973734?_trkparms=amclksrc%3DITM%26aid%3D1110018%26algo%3DHOMESPLICE.COMPLISTINGS%26ao%3D1%26asc%3D281388%26meid%3D11a38a7b5cbf4d05af73d24e14785dc0%26pid%3D101519%26rk%3D6%26rkt%3D12%26sd%3D314786647845%26itm%3D191702973734%26pmt%3D1%26noa%3D0%26pg%3D2495736%26algv%3DCompVIDesktopATF2V6&_trksid=p2495736.c101519.m5489&itmprp=cksum%3A19170297373411a38a7b5cbf4d05af73d24e14785dc0|enc%3AAQAKAAAA8MCUkZ0etk56fIj7hwaAZVedZLecyMiFU%2BvALxsJmQjueTUnf4kiHR6%2FUSaDPrGK%2FkYQTOoDgnKT1En4sbUE7tIzA2QkpXl2J%2FNjkquBYwfGufj%2FW%2BOOrzEdTDDDW%2B5AMN9FJHTWu5bGPOvKcXbdJ3CS8RVpSDcal9nnngw6ZCf5Fl%2B7kZNSHm%2FMU0A%2B5fDhbkS9Jktmb7j0sYWg%2Fsf9kcRjm%2FFWlhvuGlKO5hRPlxyppW5vEYJupgjFpQIoLoFZU0Fj68F5qjz36PBEOSuynF3ZGuKNWd2YVvKv%2F0gOs3YdxFSYfAuB6c4fUF3V0gBdbg%3D%3D|ampid%3APL_CLK|clp%3A2495736&itmmeta=01JP2DK008SX4V6HR49TEJ999R
  8. Hi friends, I want to give the best to my clients so I'm looking for the best commercial pegdope that you know? I did a little research on here and Woodland Strings came up. Seems pretty good, comes in three grades. The problem is they don't ship to Sweden.
  9. Consider a new post or moving it.
  10. It's always the functionality that matters. The player shouldn't feel the protruding nut sides on the index finger. If he does, then it's wrong. If not, it's good.
  11. You've got to start somewhere then go from there. In general I usually recommend studying Sacconi's recommendations for thicknesses. I know that Manfio has been very successful.
  12. I didn't say poor graduation. But you are right, poor graduation is disastrous.
  13. Consider that the air inside the violin vibrates when played and the vibrations are projected out through the F-holes. Mastering how these vibrations behave determines the quality. Thicknesses of the plates is also a contributing factor but less so than the shape of the arching.
  14. The best violin I've ever made (I believe) was made with zero tap tuning. No knocking on wood whatsoever. Just to prove that tap tuning is pseudo science.
