  1. There are a number of people on the West coast who are very knowlegeble but whether they are willing to write an opinion I don't know. Off the top of my head you might call Roland Feller in SF, Grubaugh and Seifert in Petaluma, or Rafael Carraba in Seattle. If they don't do this kind of certification they may know who does.
  2. No. I am pretty sure the sound does not come only from inside. Sound is periodic fluctuating of air pressure and vibrations of the plates moves air on both sides. I am thinking the pressure waves from a textured surface would be less uniformly directional and may add some complexity to the perceived sound.
  3. On a good bow definitely. On a cheap bow a replaced frog may be OK but it needs to be done right.
  4. More concerning than the gap when the bow is loose is the possibility that the threaded portion of the screw may be extending beyond the mortise. This can cause the screw to thread itself into the wood damaging the stick. Frogs and adjusters have to fit the stick and your pictures don't look like a very professional job not to mention that a bow with a replaced frog will be greatly devalued.
  5. What is mberg? I agree that none if the tuners I have used were really great although adding a tiny ball bearing under the screw and a wax lubricant helps a lot.
  6. Nice violin. Although there may be some makers who prefer a truly flat and shiny surface most do not. It's pretty hard to judge from photos but the texture you have looks quite nice and I would finish with powdered abrasive as already described. It sounds like you already have put on a fairly substantial amount of varnish and you may have tonal issues if you try adding enough to level without accenting the hard grain. If you really do want a flat untextured surface on your next violin you should start with a surface which has been smoothed several times after raising the grain and then ag
  7. Do you gate check a regular cello case or do you have a special case of some kind?
  8. Live and learn. I stand corrected.
  9. It’s not all that easy. By planing off the wood at the wider part of the neck you are also making he neck narrower and thinner. Measure carefully to make sure you will have enough wood where you need it. If you must then a wedge adding wood at the nut end of the neck may be another option.
  10. Are you sure they are varnished? Polished for sure as in smoothing the surface but I will be surprised if any strings are varnished.
