Re: Quilt Build
No not really, the joint between the body and neck is 22.5 degrees, the neck tilt angle on this one is 1.25 degrees..
so the angle cut on the neck is in 2 separate planes.. It took me a while to work it out, around 80 guitars ago, but it actually adds more meat to the join. a straight 90 degree join is actually very weak in the plane of tension, so thats why i came up with the 22.5 degrees.
Its also a natural angle as it is divisible exactly into 360 degrees, and a circle is still the strongest form to different planes of tension.
The tenon is 30mm x 50mm on the longest side and 30mm on the shortest side of the angle, even though the 30 x 30 side seems small as far as tenons go, the actual surface contact area when totalled is greater than a standard straight 90 degree tenon. This is important, as it is the surface area contact on the tenon that is the most important stress point.
the neck is re-inforced with 2, 7mmx4mm carbon fibre rods, as well as the 2 way truss rod, I also place 2 x 4mm round carbon fibre pins into the tenon from the front pickup cavity.
My neck dont go anywhere.. in fact 95% of the time, they dont need any truss rod adjustment after building. However, the rod is there because in Australia, and the US, different areas of the country have wildly different humidity conditions, and you need to be able to adjust your neck for the next 300 years or so, to maintain perfect straightness and intonation.
I do build my guitars to last at least this long... why not? the big brands are just happy selling "units", I like to make instruments.
