Re: Seating a pad

You will find get different information with different methods. Also, the force with which you suck or blow with makes quite a difference. Feeler gages are great for padding, but don't let you know if you have a leak. A leak can be the result of a crack in the wood, a ragged tone hole, a leaky pad skin, and they can occur at thumb tubes, register tubes and tone hole inserts. With a clarinet disassembled and the holes plugged up a vacuum should be strong and last a long time - until you get bored. It is good to get this base reading, so you can eliminate leaks from sources other than the pads. Then, the seal is tested after each pad.

My shop uses a magnehelic gage which puts pressure in the clarinet to determine how well it is sealing and to identify the source of leaks. This eliminates problems arising from sucking to hard and identifies leaks not found by sucking. Sucking pulls the pad surface down to the tone hole. It is rather expensive to buy for the home repair shop but worth it if you are serious.
