  1. Bass finger board dressing

    Conor & duane, Thank you for letting me know about the Traeger book. I had no idea.
  2. Bass finger board dressing

    Me, too. If I have any questions on the rare occasions when I work on basses, I consult the book "The Setup and Repair of the Double Bass for Optimum Sound" by Chuck Traeger. This book is distributed by Henry Strobel. In looking at the fingerboard sections, I see that this book generally recommends a lengthwise relief (scoop) of about 1/8 inch (3.25 millimeters), but possibly increasing this to as much as 1/4 inch (6.5 millimeters) for gut string players or bluegrass musicians. To my surprise, the book says absolutely nothing about crosswise fingerboard curvature. I think that Strobel gives some bass fingerboard measurements in his "Useful Measurements..." book.
  3. Violin bow balance/weight

    You could probably figure some of it out for yourself by experiment. Try taping small weights to different places on your current bow then playing with the bow. For weights you could use coins or small blocks of wood. If you weigh the weights, you could find out, for example, exactly how your bow would work if it were two grams heavier at the frog end. And if this made your bow work a lot better, you could have a new grip put on that was two grams heavier.
  4. TBSmithy knife

    Can you remove the blade from the handle for sharpening?
  5. Bow with Tortoiseshell frog ID

    It's nickel-mounted -- not silver.
  6. Violin Making Schools

    mapfluke, There are two things you can start working on now to prepare yourself: 1. Learn to play the violin as well as you can. This will enable you to assess instruments from a player's perspective. Try playing as many different instruments as you can. When you encounter ones that seem easier/harder to play, or ones that sound better/worse, try to figure out why. 2. Acquire tool skills. Any manual skills can help, but learning to use and maintain hand woodworking tools will be the most useful. If your school offers shop classes, take them. Even metalworking skills can be useful. Good luck.
  7. violin id

    This is a pretty typical German mass-produced Maggini-labeled instrument with the double purfling and the extra turn on the scroll. The bodies of these violins are usually over sized -- up to 37 cm -- making them undesirable. Because the top is so badly damaged this one has no commercial value, by which I mean that no self-respecting violin shop would want it.
  8. What do these anomalies indicate?

    Sometimes bits of top wood remain glued to the neck when the neck or the top is removed. The bits get removed from the neck and they disintegrate or they get lost or they are discarded. And sometimes saw cuts are made in the top edge before removing the neck or the top, so the kerf-width of the saw cut is lost on each side of the neck.
  9. What do these anomalies indicate?

    A wider neck is possible, but it's more likely that that bits of top wood next to the neck were lost during top removal/replacement or during neck removal/resetting. Then the missing bits of top wood were unskillfully replaced with what you're seeing. It may look like scorching, but it's not.
  10. Frank V. Henderson Bow

    I don't know of any. Since he was an American maker, his stuff would be most likely to appear in musical instrument auctions in this country. If you contact Skinner and Tarisio, I expect that they would send you e-mail notifications of upcoming instrument auctions.
  11. Cleat Dimensions for Post Crack

    Years ago, I asked a question on this forum about this type of crack. I received an answer from stradofear that I found very helpful. Swelling the wood with water to close the gap can work. You can read about it here:
  12. Frank V. Henderson Bow

    His bows have sold at auction for about $250 to $1000, with most going for $700 to $900.
  13. Seidel

    Very nice. What is the approximate age of this violin? Can you tell us anything about Mr. Seidel? Are you going to fit a proper bass bar?
  14. Neck width for smaller hands

    2 suggestions: 1. Have the player try instruments with various neck sizes to determine what size is comfortable. 2. Gradually carve down the neck of a junk violin until it's comfortable and use that size.
  15. Mirecourt or Mittenwald

    I have noticed that these D Nicolas violins often have one-piece fronts and backs.
