  1. What happens to strings?

    They stretch until they lose their elasticity.
  2. weirdness out of China

    It's the old "unified fingerboard theory," still looking for that definitive proof.
  3. Minimum size plane for making centre joints

    Your plane needs to be razor sharp and set to take wispy shavings, like 1/1000" or thereabouts. And I think it's best to "shoot" the joints, i.e., with the plane laid on its side on your flat bench. The plane you already have should be up to the task.
  4. Hair gauge markings....

    There are more qualified members than I to answer your question, but I'll throw in my 2 cents. The marks represent a cross section of 1/2 square mm of hair, not a particular number of hairs. The number of hairs would vary depending upon the thickness of the hair. You might notice that the slot in your hair gauge just happens to be 1 mm wide, such a coincidence! Your mark is at 6.5 square mm, which I believe is pretty typical for violin bows. But the amount varies depending upon the strength and weight of the stick. Current Arcus carbon fiber bows have a number engraved into the stick under the frog which is the manufacturer recommended quantity of hair. Here's an Arcus gauge shown with a Herdim, and as you can see they specify the meaning of the markings on their gauge. Maybe Herdim should've done that too.
  5. Cracks in Bending Ribs

    How does the water drop test work, while we're on the topic? Thanks.
  6. Cracks in Bending Ribs

    I was taught to do something similar to Berl's method, but instead of canvas I use the paper found in ordinary grocery store shopping bags. And only on the inside of the bend, between the wood and the iron, because wood bends by compressing on the inside of the curve. The outside doesn't stretch. It remains the same length it started out.
  7. Violin Strings

    Are your A strings breaking in the same place, at the nut, bridge, tailpiece? Knowing that would help to evaluate why.
  8. Johann Strad 1745 Antique Violin Repaired by Joseph Winner 1856

    More likely the neck was broken off and took the original button with it. That was someone's attempt at a repair, perhaps Mr. Winner?

    We had a Max spindle sander in the cabinet shop I worked in, a great machine, precise, vibrationless, silent. And the pattern maker's shop two doors away from us had a shop full of Max machines, among them was a 24" reversible disc sander and a 36" double disc sander with a 10 horsepower 3-phase direct drive motor. That machine used to coast for five minutes after you turned it off. In fact, pretty much all of the pattern maker's machines came from Max's own pattern shop in San Jose, CA, acquired at auction when Max shut down about 30 years ago now. My understanding is that someone continued to make that spindle sander in Asia, but I heard from a person who had owned both an original and an Asian copy that the remake didn't compare in quality. Those Max machines were a whole different class of tool, made to meet the precision demands of pattern makers specifically. Joey, your spindle sander looks like it had been left outside for a few years. I hope you can bring it back to life.
  10. Neat 7/8 violin for ID

    Correct me if I'm wrong, and I'm sure someone will, but the top has a disturbingly incorrect longitudinal arch. The back arch somewhat wrong too. Or so it seems to me.

    I alway loosen the tension on sanding drums, and more often than not I remove the sanding sleeves whenever I'm not using them. The reason for that is that leaving the rubber drums under that compression causes them to distort and greatly shortens their lifespan. Kind of OCD, but it works for me. And Edi, there was a commercial product some years ago that ran off the drill press spindle rotation, engaged the drill press's own advance mechanism, and supposedly adapted any drill press to be an oscillating spindle sander. It didn't last very long on the market. I can kind of guess why. Such a device could put 100 years of wear on your drill press quill-to-head fit, not to mention wear to the quill advance rack and pinion, in about a week.
  12. CD Audio Qualities

    I think that you and I must be the last people on earth that still collect CD's. Younger people just download digital files. Anyway, you might notice that CD's always have a marking on the packaging like AAD, ADD, or DDD, etc. These are called SPARS codes where "A" stands for analog and "D" stands for digital, and in order the letters refer to recording, mixing and mastering. CD's are always digitally mastered, but older analog recordings usually have a bit of hiss. When you look at the SPARS codes on your CD's you will probably find a correlation between the ones that hiss and the ones recorded in analog. That's just how it is.
  13. What does this tool do?

    Openers, for removing the top?
  14. mini lathe recommendation for making buttons

    Was that a typo Jeff, and you meant to say under $1000.00?
  15. DIY string jack

    After learning how to fit bridges from David B's classic video, I've found that a bridge jack just gets in the way of the Sawzall stroke, so I don't use it anymore.
