An Early 18th-Century Violin

This instrument came to us with a very interesting provenance, which we will post as the instrument moves to the Restoration pages. It is a very old violin, circa early 1700s. Check again for further information. The instrument was in a very sad state. The top and back plates, while having some damage, were in quite good condition overall. The ribs, however, were nearly destroyed and the depth of the instrument was very eratic. The neck had previously been grafted and a very poor cheek graft had been accomplished on the treble side. The back had damage in the lower bout edges at the block area, and the button had been broken off. The top required new edges throughout, a reforming of the center of the top, and a soundpost patch. New blocks on both ends, rib grafts, neck set, and color work were done to restore the instrument. I hope you enjoy these photographs of one of the most complete restorations we’ve done to date.

The first step after removing the top is to place a layer of burnished aluminum foil and oil to the top to make a casting that will support all future work.

Cross-section view of the violin top (seen as the dark line in the middle) which has been lightly glued to a flat board (bottom) that has a layer of brown paper to allow ease of removal and a casting using using bondo and a second layer of plywood (top).

to repair damage.

This shows the grafting after block
and ribs have been attached.

A button graft put into the back to replace the missing back button (interior view).

Exterior view of button graft shown to the purfling line.

Button graft, new block, and assembled ribs awaiting top assembly.

Finished button graft with new purflings and shaped into the reset neck.

The original ribs were so damaged that much wood was missing and the height varied by as much as 5 mm.

Exterior view of the rib shown at left clearly shows the original wood (dark) and the new wood of the interior graft (light).

 

The original ribs were put in molds and thinned to a feather edge on the interior damaged surface.

New wood was then glued to the original rib and then thinned to a feather edge on the interior, leaving a rib of uniform thickness.

A finished rib ready for linings.

The back is held in its casting while the ribs with new linings are fit to the blocks.

Here, the neck block and ribs have been assembled onto the new button graft.

Upper bout ribs with feathered edge at top.

Ribs are now assembled to the back and block. Note that all the white parts that you see are new wood grafted to the ribs.

Interior view of neck area artificially aged in tint only with potassium permanganate.

Here, the new wood has not been “aged” and, as you can see, looks quite out of place.

Exterior view of the lower bout ribs.

The final patch has been added to the ribs
and the top has been attached.

Neck reset and wood ready for color.

The top has now been reglued and the neck set. A yellow wash has been added to the white wood.

The top had a nasty dark overcoating in the center of the instrument, put on in the past, apparently in an attempt to hide something.

Back, before restoration coloring.

The scroll required bushing of old holes
and a cheek graft replacement.

Cheek graft finished and antiqued with first peg hole drilled. Note bushings are uncolored.

Here, the “cosmetic” magic begins. Colored varnishes are laid on in multiple coats to achieve blending of old and new.

Halfway through the process, artificial flames and an overly dark coloring which is then scraped to produce the illusion of natural flaming.

Well-disguised grafting on the finished rib.
