  1. if i make another baroque viola with cello-style box, I will likely do what you suggest
  2. thanks for all your advice -- I will likely pare back the bottom of the peg box and see where this takes me. This isn't a big deal as I haven't installed the T portion of the nut. Wont know for sure until I get it all together
  3. I'm setting up a viola with a cello style pegbox using at t-nut. I was inspired by the Archinto viola I saw in the flesh this summer at the RAM. Carving the scroll was a lot of fun. Long story short, I really didn't think the setup through. The nut on the Archinto is about 10 mm and the t-part across the peg box is another 6 mm so the result is the strings actually dig into the T part of the nut possibly even through to the pegbox itself! See the photos below. My question is this, is there anything that can be done to minimize this before I finalize things? Possibly Pare back the slope of the peg box before I install the T part of the nut? I decided half way through to do this in baroque setup (with a morticed neck) although this shouldn't affect the the nut Any guidance would be helpful!
  4. Not sure what's real and what isn't with you Melvin!
  5. very nice! I remember the cello you exhibited in Toronto very well - It looked fabulous and sounded just as nice -- highlight of the show for me
  6. What a beautiful cello! Is this one similar to the one you exhibited in Toronto last year?
  7. This is about the smartest thing I've seen here in ages! Thanks for the tip Mike.
  8. love the texture Tets -- really nice work!
  9. I use a no 7 lee valley jointing plane, flat blade and a shooting board. 3-4 passes, glue right away, rub joint. no clamps.
  10. I've used the Holtier varnish and it is quite similar to the Hargrave varnish described in the bass book. My experience was that it needs to be applied in very thin coats. The colour on its own is very nice. Here is a sample
  11. Yea me too -- madder always turns red with alum -- or brick red. I've use potassium carbonate to extract the colour for both madder and cochineal (and precipitate the lake). It is very base and I'm wondering if this has anyting to oo with the magenta of the cochineal lake. Sorry I'm not a chemist!
  12. love to hear how one shifts cochineal to red -- I always get magenta when I use alum as a mordant
  13. additional cool HIP performances Concerto Italiano with Rinaldo Allesandrini and Rachel Podger on Channel classics
  14. If you are using the Stanley No 5 as a jack (ie to remove the high spots on a board) then it doesn't need to be totally flat. For a plane this size it will cost more to buy the equipment to flatten it than it will to buy a Lee Valley or Lie Nielsen plane. I've used both and they work great.

    I think I will get one of these -- did you get the 60 in one? Large enough for a cello?

    These grow tents look promising but I cant see a way to attach the lights to the tent structure

    The chart Thomas posts above and the the data sheet I attached for the Philips actinic BL bulb looks like the peak is at ~375nm. Which is what Koen Padding suggested for drying varnish in his VSA article "use of ultraviolet light sources in Lutherie" This isnt my area and I'm also struggling with purchasing bulbs for a new cabinet. If i'm reading correctly, Thomas's suggestion of the Philips Master Actinic is spot on

    i think this is the same product Thomas refres to above
  19. Hi Nick, I like the way it looks and it appears to be quite durable
  20. i've used the Holtier Brown varnish -- the varnish alone is priced the same as other solutions. One bottle (~$125 will do 4 violins). It works well. colour on its own is similar to the Hargrave varnish. I agree with E above -- the alchemist varnish is also useful - I use it as a ground mixed with pumice
  21. T&T is perfect for furniture -- just rub the coats on very thinly and burnish off. It isn't suitable as a violin varnish
