  1. Mr Zuger, Putting aside the error-strewn nature of your highly misguided amateur pseudo-analysis, have you ever stopped to consider that it might be the utter contempt you show for other people that stops them engaging with your crackpot ideas?
  2. There are some fantastic pictures here - if you (or anyone else) knows of another thread with peg pictures, I would also be very keen for a link to it: [NOTE: Link to thread doesn't seem to be working - edited to text, below] https://maestronet.com/forum/index.php?/topic/343092-baroque-pegs-and-end-buttons/
  3. This statement brings to mind (for me, at least) the idea of equal-loudness contours, and raises the question of how (or where in the frequency spectrum) real-world violin "loudness" ought to be measured to best match human perception.
  4. I am also getting the same behaviour that Jacob is reporting. Older versions of the same page used to link to the the last comment of a post, and all featured a url that ended "/&do=getLastComment" whereas the current version does not (while pasting this onto the end of the links does work, it is obviously not very convenient). The original link behaviour can be seen using the wayback machine from earlier this year: https://web.archive.org/web/20210716132700/https://maestronet.com/forum/index.php?/forum/4-the-pegbox/
  5. Have you got a feel for how much the Hanning windowing that i being applied to input signal is influencing the apparent noise in the output spectrum?
  6. I think you are being a little unfair to the students, personally: I've read their thesis, and think they did a pretty good job of representing a complex structure in FE software, and were sufficently conscientious with their verification of the predicted model (at least as far as they were able) by study of its parts. Obviously there were other things they could have done, and other references they could have chased-down, but it's a Masters not a PhD and time would have been tight and I think they have offered balance in their write-up. The burden of proof needed for a peer-reviewed publication (ala Mr. Carlson) is significantly different to that of a masters thesis (Messrs Tunid and Varela), which is in turn significantly different to a random crank with a website who seems determined to start their own cult...
  7. While a tall thin bar should add bending stiffness over one that is more square, it presumably loses torsional stiffness quite quickly as well: As with all-things violin, the performance of the parts are so bound up in the performance of the whole that nothing is obvious, but I wonder what broad-scale behaviours this might affect.
  8. No problem - if you send me a pm with the address you would like it sent to, I will get it in the post later this week. If you would like the rear-adjuster or cap-retaining-screw for spares, let me know and I will include them (the other moveable bits are are all heading onto my replacement)
  9. The bed on my 60 1/2 started to "peel" back from the mouth a few weeks ago, and I have since bought a replacement. If you haven't found a local replacement (or decided to try something else) by the time I have refurbished mine (about a week, I hope), I would be happy to send you the cap from mine.
  10. I'm not sure it's even safe to conclude that - he might have cut down a tree comfortably large enough for a cello top, and used the old growth tip-of-the-wedge for a bonus violin top.
  11. I've seen this equation before and not really bought-in - is it not a simplification too far? Would not the equation be better approximated as: Z = G(M, f) . f to better-reflect the distribution of mass around the nodal lines in different frequencies, rather than treat the mass in motion as monolithic?
  12. There's a fantastic picture on Guy Harrison's website here that gives some insight into the illustrated scrapers.
  13. They can also be seen here, as well: https://maestronet.com/forum/index.php?/topic/343116-jacob-stainers-birthday/&do=findComment&comment=851754
  14. I agree completely, but think there's a fair bit of value in an interactive 3D model - being able to interactively slice in x, y and z is something I find extremely useful. Have you looked at converting your Matlab-generated model to a web-friendly format, and getting it into the browser (and possibly sharing online)?
  15. ...I thought they only got used as makeshift goalposts when it was too cold to take a coat off, but I can see that would work too.
