OUCH! Don't Use THAT For Emergencies

When emergencies arise, directors sometimes have to improvise. When you find yourself in that situation and need a quick fix to get by until repair is available, here are some important tips.
DON'T USE:
-
Rubber Bands. Commercial rubber bands are vulcanized--a process where they are treated with sulfur to improve elasticity and flexibility. When a rubber band is stretched, this creates heat. Sulfur degasses onto the object it is wrapped around. This will molecularly burn into materials used on band instruments including silver, brass, and lacquer.
-
Super Glue. Although this product does have its uses, and is readily available at supermarkets, this glue contains "cyanoacrylates". When heated, this releases small amounts of cyanide gas and can be harmful to the technician removing this material. We use heat in the forms of flame, heat guns, and friction.
-
JB Weld. This resin and hardener mix-type epoxy should not be used on instruments. It is incredibly difficult to remove, and the process of removal can cause damage to lacquer and silver plating.
USE INSTEAD:
-
Zip Ties, Electrical Tape, Painter's Tape. These will usually get the job done (temporarily) without damaging the instrument.
Most metal-on-metal connections on instruments are solders. This is a metal blend that is melted and cooled between two other surfaces of metal. The metal blends have different melting points and allow technicians to repair multiple applications to prevent burning and blistering lacquer or silver.
