| The following is another brief photo description of the making of an
aluminium bodied 4/4 size violin, the overall measurements are 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 Bridge centre height 32.3mm Middle bout 112mm E string height above fingerboard 4mm Bottom bout 208mm G string height above fingerboard 5.5mm Rib height 32mm Fingerboard to bridge 52mm Body stop 195mm Tailpiece saddle to bridge 47mm Neck stop 130mm Saddle height above belly 4mm Fingerboard length 270mm Vibrating string length 325mm (standard 2:3 ratio Total length from top of scroll to endpin, approx. 600mm The arching are: top plate 14.4mm, back plate 12.4mm. (Actual concavity: top plate 13.5mm, back plate 11.5mm.) with 0.9mm aluminium used for the plates, ribs, bass bar and joining clips. As an added precaution it also has a central 350mm x 12mm x 1mm aluminium tube to impart additional stiffness, (otherwise the thin aluminium plates on their own, may stretch slightly under the string tension and allow the fingerboard to drop.) * Using the thinner 0.9mm sheet, care has to be taken when countersinking the screw heads, not to drill too deep. The neck, blocks and sound post are again made from unknown wood from a yacht's spar, with ebony finger board, nut, end pin, pegs and tailpiece, with an aluminium saddle. It originally had an alternative home made tailpiece, made from 1.6mm aluminium, which I think gave it a brighter sound than the ebony one. The estimated finished weight with chinrest attached was 730grams, but the actual finished weight is 750grams, just slightly heavier than estimated. (the weight of a normal 4/4 sized wooden violin is approx. 450grams. The strings are: 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 D - D'Addaro Prelude J813 D-Re 4/4 Nickel Wound, Medium Tension G - D'Addaro Prelude J814 G-Sol 4/4 Nickel Wound, Medium Tension |
