The cello side shown below is from an 18th Century German cello made in Mittenwald by a member of the Klotz family. The ribs over the years had been cracked in various places and had some wood worm damage as well.

It was brought into the workshop for restoration.

We used a variety of techniques to reinforce the many cracks in the ribs. In the example above, a crack in the rib ran right next to the spruce lining inside. To avoid removing, or cutting the original wood my assistant fitted 3 spruce studs inside going from the rib over the lining to reinforce the crack. So no original wood was lost or disturbed and the crack is held closed.

The end of the studs are cut at an angle in an effort to avoid future cracks.
