Peter K-G Posted October 5, 2013 Author Report Posted October 5, 2013 I do look for very high speed of sound in spruce, but for maple, I'm not convinced that exceptionally high along-grain speed of sound is even desirable. Lower arch works with high spead of sound maple
Peter K-G Posted October 5, 2013 Author Report Posted October 5, 2013 While waiting for my toothed blade plane, I managed to find some time to start the neck. For me this is just measuring a few points and freehand drawing. I'm not sure I want to post all the ugly stages when I carve the scroll. It's not clean and precise work like I have seen others do here. I just saw a carve.
Don Noon Posted October 5, 2013 Report Posted October 5, 2013 Lower arch works with high spead of sound maple I don't disagree... but I'm curious; how do you know this for a fact?
Peter K-G Posted October 5, 2013 Author Report Posted October 5, 2013 Violin #5 had very high speed of sound (compared to #4) and I was able to tune the arch ~1,5 mm lower to achieve equal M5. It was also possible to go 7 g lighter, even though #5 had significant higher density
Don Noon Posted October 5, 2013 Report Posted October 5, 2013 Oh, so "works" means achieving certain plate weights and taptones. If you can demonstrate how that affects the tone of the finished instrument, that would be much more interesting.
Peter K-G Posted October 6, 2013 Author Report Posted October 6, 2013 That's what I'm working hard on: http://www.maestronet.com/forum/index.php?/topic/327789-body-modes-as-violin-sound-equalizer/ Achieving certain plate weights and taptones + Body modes Hz and dB is the physics and logic behind it,as in your comment: http://www.maestronet.com/forum/index.php?/topic/327789-body-modes-as-violin-sound-equalizer/#entry574641 Don: "Here's what I did and this is the result and why it's that way"... needs the physics and logic. In addition to that It's intuition and getting use of my "beauiful mind" The rest is subjective to which is difficault to find any other proof than a virtuoso buying an instrument or a violin competition.
Peter K-G Posted October 6, 2013 Author Report Posted October 6, 2013 Not clean and precise as i sayd but... I and so on... I think it will be a nice one.
Peter K-G Posted October 6, 2013 Author Report Posted October 6, 2013 It has been a rewarding day, Scroll and neck roughly shaped and everyting seems to be alright, 5 hours effective work, 90 g now at this point.
Peter K-G Posted October 9, 2013 Author Report Posted October 9, 2013 Traveling I need to find out how to pack knives and wood in my suitcase and get it through security control, then I could do some work at the hotel in the evenings ...
Michael_Molnar Posted October 9, 2013 Report Posted October 9, 2013 Traveling I need to find out how to pack knives and wood in my suitcase and get it through security control, then I could do some work at the hotel in the evenings ... Check the suitcase in at the airline counter. You can't take this stuff with you on a plane.
Peter K-G Posted October 12, 2013 Author Report Posted October 12, 2013 Well, got home and straight to the workshop, 74 g will be ~70 g when finished:
Peter K-G Posted October 13, 2013 Author Report Posted October 13, 2013 Some maple is just more difficult than others. tried to plane the joints of the back today, but it tears out in the curls. (Se Planing ribs: http://www.maestronet.com/forum/index.php?/topic/329155-planing-ribs-how-to/?hl=%2Bplaning+%2Bribs) I'm still waiting for my toothed blad plane so no progress today. I could do it with my old Stanly 102 but I want to start doing things more "professional" It's good to have the neck/scroll ready so it won't be the last thing to do. The scroll was inspired by Roger Hargrave's double bass scroll. Of course you can't copy a bass scroll to a violin scroll, but I think It's a good thing that Inspiration can come from contemporary makers. It doesn't allways have to be an old instrument. http://www.maestronet.com/forum/index.php?app=core&module=attach§ion=attach&attach_rel_module=post&attach_id=22632 http://www.maestronet.com/forum/index.php?app=core&module=attach§ion=attach&attach_rel_module=post&attach_id=22622
Peter K-G Posted October 18, 2013 Author Report Posted October 18, 2013 I'm using my bench as a diary and testing ideas in other topics. Is it possible to recognise a Strad or DG sounding violin? Hmm (yes it is) I have a lot of opinions about the 2013 VMAAI finalists, but it's not respectful to the makers to comment that. The Shure SM8 mic is ~40 cm above the f-holes and the violin is shouting as loud as I could play directly into the mic without any software manipulation. No echo from the room either. Just the naked truth of the violins. No suprise that this was a very unpleasant experience to Maestronetters. BruchV5_Shure_Take_A.mp3 BruchLJ_Shure_Take_A.mp3 Bruch beginning is a fantastic piece to here the raw sound of the G string and the reflection of the violins body modes. G Bruch.mp3 If I had more time I would be working on #6... so it's sound analysing instead for now.
actonern Posted October 18, 2013 Report Posted October 18, 2013 "...Is it possible to recognise a Strad or DG sounding violin? Hmm (yes it is)..." Roger Hargrave... any thoughts?
Don Noon Posted October 18, 2013 Report Posted October 18, 2013 If you define "Strad sound" and "DG sound" in a specific way, then yes, you could probably sort out violins that sound one way or the other. But you'd probably sort out some Strads as having the DG sound, and some DG's as having a Strad sound, so I'm not sure I see the point.
Peter K-G Posted October 24, 2013 Author Report Posted October 24, 2013 Found some straight spruce wood profiles for corner blocks:

Peter K-G Posted October 25, 2013 Author Report Posted October 25, 2013 A much better player than me tested my violins last night. In respect to him I will not post the sound clips. He does not play so often anymore but can get the most amazing sound out of violins. Beside Cremonese sounding violins you need a player that can bring this sound out of the violins. This is a Polish tango: Notice the curve after 4 KHz.
Peter K-G Posted October 26, 2013 Author Report Posted October 26, 2013 Todays work; Blocks cut, ribs planed to 1,1 mm, new fantastic tools (but it's still work huh..)
Guest Posted October 26, 2013 Report Posted October 26, 2013 I don't like the looks of that endblock...besides having a knot it looks cracked. Or is that a pencil line?
Peter K-G Posted October 27, 2013 Author Report Posted October 27, 2013 I don't like the looks of that endblock...besides having a knot it looks cracked. Or is that a pencil line? It's a pencil line marking the center. I'm going to conseal the knot with ribs, no one will ever know (CT will of course show the knot later, when they scan the violin to try to figure out twhy it is so great)
Peter K-G Posted October 27, 2013 Author Report Posted October 27, 2013 Today C-bouts bending This was one of those days when I should have stayed out of my workshop. Cut my self terrible in the tumb on my home made bending strap: Decided to continue anyway without it and didn't manage to do a perfect bending job. Then I couldn't find my clamping blocks and started to improvise... It worked out OK in the end, but this is not an image I like to post:
