  1. Found an interesting piece about guitar temperament for anyone curious.
  2. Things you learn when you're just starting out: Sanding down the shaft of a violin peg by even a small amount will have a huge effect on how far it goes into the pegbox. For a peg with a standard 1:30 taper, taking as little as 17 microns (0.017 mm) off the surface of the peg shaft all the way around will cause the peg to shift in the peg box by 1 mm. For scale, this means sanding down the surface of the peg shaft by the thickness of a piece of printer paper (about 100 microns) will cause the peg to shift by 6 mm, which is huge. So this is how the head of peg I was "lightly" sanding to ma
  3. I haven't tried it, but I doubt the camera is quite that sensitive.
  4. This is only meant to substitute for the specific trick described in Johnson & Courtnall where you touch the peg to your lips. If you don't do that or you don't need anything more precise then of course there would be no point to the IR camera. Luthiers have managed to do without infrared cameras literally for centuries so it's not like this is really necessary, but I find it an interesting visualization and a possible aid. It's not intended to be the sole method by which the fit of the pegs is judged.
  5. In Johnson & Courtnall's The Art of Violin Making the authors suggest that in order to test the fit of a new peg one should spin the peg in the peg box and touch the peg against one's lips to make sure both ends of the peg are equally warm where they touch the peg box. I tried this and found it difficult to detect any heat with my body, so I figured I'd use my infrared camera (FLIR ONE Pro) to gauge the temperature. You can see at first glance in the last two pictures that the peg does not have good contact with the left peg box wall, so I will need to shim the peg in the shaper or adjust
  6. I suspect it was something that others consumed.
  7. I don't care how good your software and equipment are, in the end you can't get around the fact that light travels at 299,792,458 meters per second and needs to travel both ways for any kind of live interaction to take place. Add other sources of latency and you can just forget it.
  8. I have no personal experience with this, but most of what I read some number of years ago while researching the matter leads me to believe that either a small diaphragm condenser or a ribbon mic would be best for recording violin. Here's one article suggesting the same: Fiddle Fiddle Big and Little Of course, the microphone is only one factor. Microphone placement and recording environment are also important.
  9. Didn't know about Reverend Morris, so I looked him up and found this blunt little gem in his dictionary:
  10. It looks like the videos are unlisted, which means anybody who has links to them can watch them but they won't show up on searches at all.
