1953 Gibson L-48 with loose tone bars

I just finished repairing this great Gibson L-48.  Both of the tone bars were loose from the middle of the top to the end block.  The trick to this repair was figuring out how to complete all the necessary operations with access only through the f-holes.  Using a gooseneck web camera to see inside the guitar I managed to inject glue under the bars and clamp them with long reach clamps.  You can see the whole process here.
