The
following is another brief photo description of the making of an aluminium
bodied 4/4 size violin, this one is bonded together with Araldite Super
Strength two part exopy resin.
The overall measurements are again from 'Juliet
Barker', the contour templates are for a Sacconi Strad 1716 & the
neck/scroll dimensions are from 'Strobel'.
The completed specifications are:
Body length 355mm
Top/end of fingerboard to belly (19.5mm)
Top bout 168mm

(32.8mm)
Middle bout 112mm
E string height above fingerboard (3.0mm)
Bottom bout 208mm G string height above fingerboard (5.0mm)
Rib height 30/32mm Fingerboard to bridge
(52mm)
Body stop 195mm Tailpiece saddle to bridge

Neck stop 130mm Saddle height above belly
(4mm)
Body thickness (Internal) 59.4mm String angle 58 degrees
Fingerboard length 270mm
Vibrating string length 325mm (standard 2:3 ratio
Total length from top of scroll to endpin, 598mm
The arching are: top plate 15.4mm, back plate 13.4mm.
(Actual concavity: top plate 14.5mm, back plate 12.5mm.)
with
0.8mm aluminium used for the plates and bass bar and 0.5mm aluminium for the
ribs and rib locating/edge reinforcement strips.
The neck is Bosnian Maple, blocks and sound post are Spruce, with ebony
finger board, nut, end pin, pegs and tailpiece, with an aluminium saddle.
The finished weight with attached Dresden chinrest, with height extended by
7mm, is 582grams, which is actually 32grams lighter than the Magnesium
bodied one. The central torsional tube weighs 32grams so there is a further
possible weight saving there.
(the weight of a normal 4/4 sized
wooden violin is approx. 450grams.

E - D'Addaro Prelude J811 E-Mi 4/4 Polished Steel, Medium Tension.
A - D'Addaro Prelude J812 A-la 4/4 Aluminium Wound. Medium Tension
