Karl takes many steps to ensure that all details of the instrument is functioning properly.

This King Super 20's bell-to- body brace has been weakened by multiple blows to the bell.

This is the weakened brace up close.

Here, Karl is making the rings to be added to the existing brace. This creates two triangles for lateral rigidity.

Braizing of the final ring. Yes, he is free-handing it, just like he first saw Chip O. of Fox Bassoon demonstrate years ago at a NAPBIRT conference.

Karl, looking to affirm proper clearance between added ring and posts for brace. This repair was made in 2007 and the modification has worked very well.
