Bond. Clarinet Bond.
I once had a young clarinetist bring a horn that looked just like this into my shop. When I asked her what happened, she smiled sheepishly and told me her dog sat on it. Her nintey-five pound dog. Snapped the receiver on the lower joint right off.
These are the tools I use to clean the horn parts prior to rebonding them. It is a simple process that saves the customer hundreds of dollars as opposed to replacing the entire joint. There are four simple steps involved in this process: Clean! Bond! Clamp! Wait! The Armstrong clarinet in these pictures is now now enjoying another season of Texas High School Marching Band. Upon finishing this job, I did the same repair to a a couple of Vito Bass Clarinets.
