  1. I find the B&G book worth every penny. The instruments are very well chosen, the pictures are superb, as is the print. I can understand why some of you don't give so much value to Greiner's part, but I think it's a mistake . We all have to figure out what to do with the science part, and I find his interpretation pretty good. My 2 cents...
  2. Valid point, but.. The instruments we want to emulate (not all of us, I know...) would have been properly restored. There are very few Strads with ugly cracks, so I'm not gonna make one just because it might look old
  3. Another thing. For one large-ish scratch, make 10 medium ones, 100 small, hardly visible ones, and 1000 that won't be visible unless you use a loupe. When you're done, clean the large one because that's what almost anyone would do on an old instrument...
  4. Cooked rosin (limed) with washed and cooked linseed oil, nothing fancy. Rosin to oil 2 or 3 to 1. The varnish itself is cooked too, it's not a cold mix. Turpentine and a bit of spike oil to spread.
  5. My freshly applied varnish is strongly fluorescent white, and upon drying it becomes duller and goes towards an orange fluorescence. Can anyone explain that?
  6. If you consider that the oil and the resin separate over time in a cold brew, it's also likely that the ratio changed... I find this very interesting btw. On another subject I'm still puzzled by BB finding a protein layer and Echard not... I you test my instruments you will also find it on some, on others not, on some only on the spruce, but they both seem to get consistent result, just different ones.
  7. My experience is that if you use a very lean varnish (4:1),it sets so quickly that you have no chance to varnish a cello. Adding a little bit of raw linseed oil slows the tack time considerably without changing the proportions so much. Brigitte Brandmair, with whom I talked about that, thinks it would explain the different crackling found on cellos vs violins. As for a lean varnish being too brittle, I noticed my varnish becomes tougher with time, and the various layers of polish melted into the varnish probably softened it a little.

  9. This sharp edge is very practical to have a clean finish att he collar.

    New Hill violins

    That's a shame, I'm sure I'd have loved it!

    New Hill violins

    Ok, leave Stradivari and Bergonzi aside.. (I saw a violin certified as Bergonzi a couple of months ago, I could have sworn the scroll was a 1720's Strad...). That wasn't the point anyway. My point is that team work can be better than a one man shop. If I start experimenting with new varnish, or if I try to understand how I can use modal analysis, nothing gets built in my shop. So I progress less than if someone was helping me out.

    New Hill violins

    I don't get all he fuss about instruments made by teams. We can go pretty far back to find that it was the case in most great workshops. Are some Stradivaris worth less because one can clearly identify Bergonzi's hand? What about Vuillaume? Why should it be any different when it's Greiner, Hargrave, von Baehr...? Being alone means one has to produce violins to live, and leaves less time for experiments and progress, and very little time for error...
  13. Try sonowood. Only we can establish the decent track record.
  14. C'mon, we all know this is the only proper way to fit a bridge!
  15. Don't worry, no one can.. Thank you for the great picture Manfio! More interesting than the wing imo is the way the flames are better sealed along the purfling... Glue ghost from purfling? Or can it just be from the shark skin finish?
  16. I Mix larger batches in jam jars, I don't measure much. I stir if I want more red, as pigments tend to settle after a while.
  17. As far as I know, all medio fino have pressed plates. I have a cello with pressed top and back and real purfling
  18. It is! It's actually varnished, I'd be happy to send it to whoever wants to set it up. Just let me know!

    New Eyes

    I'm starting to feel the effects of age, and I can't fit a soundpost with my glasses on. in a way it's quite practical to be so short sighted.. But I realise every time I do an arching how my glasses distort my vision. I did an experiment once, and made a plate without them, it turned so much fuller that what I normally do, and I had to start all over again. If I get surgery some day, it will probably take me 3 or 4 instruments before the arches go back to normal...

    Yellows

    Cornelissen's tartrazine yellow is, as w&n's Indian yellow was, tartrazine Lake. No need to look further if you want to keep using the same stuff.
  21. Yes cooked rosin and some cochineal lake
  22. Not what I meant to do... I somehow edited the last post. Anyway, the back and scroll are done, I hope to be able to send the violin over in a week or so. (after I finished the front and ribs of course!)
  23. Nope, I cooked this one long ago, but I guess it's Kremer's clear stuff.
