I don't believe this is possible without a harp tail. And that would be a custom made tail, not off the shelf. Also, with an original 4ths x 4 afterlength established, it would vary over time and and across string tensions.

Thank you much! Happened with two batches. Only similarity seems, both guts broke at the point where threads went to solid core. In both cases, the break point was above the saddle and below the tail holes & tail wood. The strings appear as 'older' Helicore Orchestral. The projection on bridge...

Touche' Send me the first drawing, I'll make it and you can experiment. Test on standard Strad model: -14" lob - 8.5 & 6.75" bouts - 0.6" plate arch w/ Strad taper to e, n & t - 1. 33" ribs - bracing lumber std. Spruce of my stock Matthew [email protected]

The experiment kind'a has been done, thou poorly adept. First glaring issue was transference of low with high frequencys. I think that simple idea of 1-2 bars or braces is not crafted via science. Couple thoughts by me that may not pan out. The magnitude of treb side vibrations generating by...

I trust over past months you have trashed this thought. Violin and gamba family instruments have a bass bar and a sound post for 3 simple, intuitive reasons. Principles have been understood since long before 1500. A tall bridge causes pressure to soundboard, which will deform and/ or collapse...
