  1. Perhaps already discussed in MN, but if not... https://onlinelibrary.wiley.com/doi/10.1002/anie.202105252
  2. After 15 years of supplying tonewood, and at 65 years of age, I decided to sell out. But I do hope to keep involved - it is hard to give up entirely! Now to concentrate on my violin making. Thanks to all.
  3. I have been using the Veritas pot for a number of years. I like it a lot. I did not buy the warmer, however,so I cannot comment on that. I drilled a small hole in the center of the lid so a thermometer can be inserted. (yes, I actually use a thermometer!
  4. Light is primarily the factor whether branches persist, as I recall from forestry school 40+ years ago. David's kindergarten experiment is quite illustrative of this. If a seedling begins life shaded by a dense canopy (overstory), and conditions remain that way, it will "reach" for light and send its energy producing foliage mostly at top of the tree. The spruce will also be tall and spindly, so when it grows large the branches may be small and not extend far from the heart. I have found best red spruce where intermingled in intensely dense hemlock stands. Other factors may bare but I think light availability is the primary reason for low branches. All the spruce in my locale are owned by US Government or Weyerhauser Corporation. Neither entity engage in such intensive silvicultural practices as clubbing lower branches. The latter clearcut everything to promote hardwood regeneration.
  5. Yes, trees do not put on girth in winter, so correct terms are early wood and latewood.
  6. This is unfortunate, but true. I think that if a tonewood cutter uses such terms they should be accurate to where the tree grew. I cut a lot of Red spruce in my locale (Picea rubens) - and I called it red spruce. But in the steel-string guitar world "Adirondack" it the hot term, and is widely and misleading used for Picea rubens. Very little red spruce comes from the Adirondacks. Personally, I do not adhere that regional differences are significant, as there are many more important factors affecting tree growth. There can be a lot of difference in trees from the same plot, and indeed even within the same log. Trees really do not care about political borders. :-)
  7. Not to belabor this discussion, but the pattern drawn on this piece, has the annular rings running laterally. I assume it is not large enough to orient the grain properly for a violin. I agree it is likely from a crotch . I have cut many similar pieces when cutting maple logs, but sold to cutting board makers cheap. Very prone to movement, especially at thicknesses of a violin.
  8. I use GE F40TBL, and have for years. I just got some new tubes from 1000bulbs.com at $7 each.
  9. I have been using Klean Strip Green Denatured Alcohol since Everclear 190 is not readily available for me. Claims to be 95% Ethynol and I have had no issues french polishing shellac.
  10. Ioan Luca is (was?) a maker in Reghin RO. He was born in 1936. Gabriel Croitoru (who now plays on the Cathedral dG) played one of his instruments some years ago, I think.
  11. As of yesterday, November 11, Woodcraft in Columbus Ohio has 1 bottle. And they cannot get more!
  12. In handling many 1000's of guitar tops (where flexing is practicable), I came to the conclusion that grain spacing does not necessary correlate with lateral (cross-grain) stiffness. Longitudinal stiffness isn't so easy to assess, and perhaps there is some correlation - or effect?
  13. Anchor seal is great, and I've used buckets of it with success. But you probably don't want to buy a gallon. If dipping in wax, you have to hold it in the hot wax until the wood gets hot enough for the wax to adhere. White glue or Titebond is OK. However, I don't usually seal spruce,. Instead we cut the billets long to allow for later trimming. If it's prone to cracking, I want to know. Yes , remove bark and absolutely store outside with good airflow. I've never had issues from freezing. I like to hang maple when possible, but for spruce, which goes to EMC relatively fast, "log cabin" stack is just fine.
  14. Willow is actually very tough due to interlocking grain. Cricket bats are made of Willow.
