Final assembly: Strings On!

Mark Wood-style tailpiece/Strandberg tuner geometry is just about perfect Arrr mi-Garrrd! Fingerboard looks pretty damn straight! F string is just about 5.5-6mm above the end of the fingerboard. A string ~3-3.5mm. C string is 1/4" too short. I don't think it will affect the playing. The Cello A-string really looks too thin. About the same thickness as Viola C. Maybe try Cello D and move cello A up to viola C? That would certainly be long enough. A fine-tuning adjustment point. If the body is strong enough to hold a tuning, then I think it is playable. Next: Install the volume control, output jack and do the wiring. I'm going to put some 3M tape primer on the backside of the bridge (from the self-adhesive vinyl kit) for the benefit of the double-sided tape of the transducer. #StrandbergGuitars #D'Addario #Helicore #5-string #extended-range #viola #electric #Rock'n'Roll #Shapeways #Custom #Knock-off #Wood Violins #Viper #Novel #Improvements #J.W.Winco #Locki...

Final Assembly: Violin Making: The Bridge

Image
  Original bridge on this instrument was a "standard" (meaning nothing) viola bridge, and the attempt was to make this bridge exactly like it. Compare to: https://href.li/?http://www.makingtheviolin.com/Bridge

The Search for Strings

  https://href.li/?https://maestronet.com/forum/index.php?/topic/355894-octave-viola-strings/ https://href.li/?https://www.daddario.com/globalassets/pdfs/accessories/tension_chart_13934.pdf   A complete technical reference for fretted instrument string tensions Catalog Supplement/String Tension Specifications Their version of the magic formula features a mysterious constant (386.4). If you use it, the string density results seem plausible.  Anyway: I was trying to find out if I could put guitar strings on an octave-viola. So I wrote a python program to generate this table: c2: (e2) 1.66  (a2) 1.90  (d3) 2.01  (g3) 2.02  (b3) 1.61  (e4) 1.61  g2: (e2) 1.61  (a2) 1.85  (d3) 1.96  (g3) 1.97  (b3) 1.57  (e4) 1.57  d3: (e2) 1.71  (a2) 1.96  (d3) 2.07  (g3) 2.08  (b3) 1.66  (e4) 1.66  a3: (e2) 1.33  (a2) 1.53  (d3) 1.61  (g3) 1.62  (b3) 1.29  (e4) 1.29  Each r...

Lessons Learned, Part 1: The Fingerboard is Too Narrow, the Strings are Too Short

Image
When projected onto the bridge, the fingerboard is really about 8mm too narrow. The fingerboard and tailpiece elevations look good.  https://href.li/?https://www.mycorene.com/_files/ugd/fdad7c_d1b9584e17cf4d4b9a164c03ed9a965a.pdf CAD Model / STL file top surface, 311mm 5-string Viola Fingerboard -- Extra Wide & Long Helicore Strings are too Short!

And, they have been out-of stock since December. The angled tailpiece combined with the Strandberg tuners ... Unboxing the Nylon, 3D printed fingerboard from Shapeways  

The Custom Tailpiece, A Design Improvement over Mark Wood's Viper

Image
A headless viola has the tuners on the tailpiece for better balance. https://href.li/?https://strandbergguitars.com/ The Mark Wood Viper tailpiece is already peculiar enough to require special extra-long strings. We are compounding the peculiarity in our design.
