Viol building photo diary

This page is a photographic record of the building of a seven string bass viol after Nicolas Bertrand, Paris, circa 1726.

I started it in the Summer of 2007 and I finished it at Christmas 2008.

  • The ribs (sides) back and neck are made from European walnut (Juglans regia).
  • The blocks of the body are cedar of Lebanon (Cedrus libani).
  • The front is Alpine spruce (Picea abies).
  • The bridge is made from maple (Acer spp) stained black and the nut is boxwood (Buxus sempervirens) also stained black.
  • The pegs, hook-bar, fingerboard and tailpiece are pearwood (Pyrus communis), the fingerboard and tailpiece are veneered with some beautiful burr London plane (Platanus × hybrida) with edges of black-dyed maple.
  • I use no tropical hardwoods.
The mould with corner and top and bottom blocks attached and the first rib bent and cramped to shape.

The piece of wood to the left is the second rib before bending.

All six ribs bent and fitted to the mould and glued to the blocks.

The slope on the ribs of the upper bout leading up to the top block is visible too.

The body of the viol finished, ready for the soundboard to be glued on.

The mould has been removed and the linings round the top of the ribs have been fitted. Also visible are the reinforcements to the central back joint and the fold, and the plate which supports the lower end of the soundpost.

Beginning to rough out the front.

Bertrand used the "carved" method for his soundboards. It is made from two wedges cut radially from the log (like slices of a cake) and jointed "bark to bark" to make the blank from which the soundboard is carved.

The neck ready to glue onto the body. The "heel" at the body end of the neck will be shaped to blend with the body after it has been glued.

The clay maquette of the head. It's based on a Roman female portrait bust from Pompeii, now in the archaeological museum in Naples, where I was able to photograph it.

The fingerboard and tailpiece. The tailpiece has had some oil rubbed into it to protect the wood and bring out the colour. The fingerboard will be finished in the same way.

The stages in making a peg.

The peg itself is pearwood, two cheeks of scrap maple are glued on to the head end so that the head may be turned as a complete ball without wasting a thicker piece of pear.

The blank is turned roughly round.

The taper is finished.

The turning is finished on the peg in the foreground.

The peg in the background is completely finished. The gold "pip" on the tip is a 9 carat gold ear stud.
