  1. very powerful, searing, excellent optics, world class instrument, excellent job.
  2. He's one of the most talented individuals I've seen in a long time and was floored to see that this video only had 47 views since 2012. Keeping things in the rock vein, his song writing and riffs are really quite awesome again styles and likes are all relative, as even is "talent" some people said jackson pollack had talent, I just see a drop cloth with paint splattered on it.
  3. while we're at it....at 4 min he really starts rocking
  4. well one thing is for sure, general information does not hold monetary value like it used to, so it'd need to be done as a labor of love
  5. if you live in an area with oak trees you can find some "oak apples" or "oak galls", which are whitish balls that are like a hard foam, they are full of tanin. Simply place oak apples in water and toss in a piece of steel wool, let it sit for about week or two, sloshing it around every once in awhile during the process, this is the basis for iron gall ink, it will be very watery at this point and can be applied as is, in this case soak your strips curled in a bucket, the longer it sits the blacker it will get, if it sits long enough it will saturate color all the way through and not be able to "scrape" of the color. It is a very black black with a slight blue undertone If you want more body to the fluid, simply grind/powderize egg shells and add that as a thicken agent . when applied to paper and allowed to be exposed to oxygen it has been shown it has about a 600 year shelf life before it starts to react with the oxygen at which point it will degrade the paper, however in this case, as it is sealed over with varnish , it will not get air exposure so you should be good for at least 2620 this reaction, iron with tanin is also seen in "incise" purfling, where the mere act of cutting the channel with a reactive blade{not stainless} over time will start the process, so not only does varnish pool in the cut channel and darken it, but the iron from the knife blade will react with the tanin present in the wood and show as a black line. if you ever had old wood floors that were covered in carpet and then refinished, often time there are many very thin black lines that are often too deep to sand out, this is caused by the carpet installers knifes cutting into the wood when they cut there carpet, also when the demo old carpet and then put new back down... make sure you test your soaked strips to ensure they are stained all the way through. Often times soaking then drying and repeating several times helps saturation
  6. I agree with you for what it's worth....there are mineral streaks, then there are worm tracks. Mineral streaks show up in a variety of different ways and shapes, kook at "Ambrosia Maple" which is basically maple with huge swaths of mineral, but yes in my many years, we call them mineral streaks, as far as the violin in the pic, I think it's old with some scuffs and that it was dropped on something that had 'symmetry" and dented it.
  7. yes send them the link, then they can "monkey see money do without the 2 hour community college course on "the violin and all it's parts"
  8. Very informative, yet at the same time reminds of the times I've had to teach employees on the proper way to empty a 5 gal bucket. The only thing I would add is that its a good idea to put a bubble roll in the case next to the heel and any void that may exist in the neck area, as many cases differ. This prevents "whiplash" neck cracking that can happen , even if the box and all wrapping makes it so the case is "frozen" in the box, if there is any "wiggle room" within the case, in a whiplash like motion, as in dropped or tossed, the weight of the neck,scroll and fingerboard can break itself, so by freeing the instrument in the case and not giving it any room to "whip" you can prevent this....It's a big problem with guitars more than fiddles based on size, but it could happen, so better safe than sorry.
  9. If I were you I would be bringing this is in to a reputable shop. I have a strong suspicion this is the real Macoy, if not it was a forgery done by someone who had an original label in front of them. It does look like it has some 'chopping and channeling" The ff's have definite similarity to some of his other work, as well as other details. .https://www.oregonlive.com/pacific-northwest-news/2010/11/marconconi_violin_worth_50000_reported_missing_from_mobile_home_in_corvallia.html an example
  10. In guitar land there is much research related to this, and or how the mass of the neck, and particularly the headstock mass contributes to the dynamics. Ir has been somewhat determined {by someone I don't know, but I do "buy it"} that a tapered gradient of mass lower going to a light upper, in this case scroll is better for not robbing either through de-constructive motion or damping . So with a violin fingerboard, there is so much natural taper that the fingerboard pretty much does this naturally. However in the case where you may have the ability to cut your own out of a blockblank, or more importantly on a guitar that does not have the amount of taper that a bowed instrument does. It is a good idea to draw a center line and then place the stick on a fulcrum point to see if it has a uneven weight distribution, and or when balance on the center, is one end of the stick heavier than the other, if so, put the heavy end down over the body and the light end up at the nut.... with violins, how important this is could be debatable, but with guitars its very important as well as keeping the headstock as light as possible... the basic physics being the '"flagpole effect" I can not help but wonder if this principle was not a "secret" that seemingly has not een discussed that I am aware of related to choosing wood for the plates. when we talk of variation on material, that to a certain extent is what we are talking about, now, a large portion of wood is pretty evenly distributed , but there definitley are peices of wood that have dramatic weight differences withing the same piece whereas if balance on a fulcrum, the balance point can be way off center. I do not recall every discussing or reading about this aspect, the weight gradient distribution and looking for it when choosing wood....seemingly if one did find such a board,based on the principle {if it applies} we would want to have the heavier end in the lower bouts.
  11. Makes some pretty good guitars I've heard, have not used it myself.
