Homemade Leak Light
For occasional home use, it’s handy for a sax player to be able to check for pad leaks. Here’s one I built for just a few dollars, it’s long enough to check my bari and skinny enough I don’t have to remove any pads to use it.
I started with a coat-hanger, straightened it out and bent a small crook at one end.
I wrapped it with two-strand wire. The gauge is not too important. Both voltage and current are low.
At the unbent end, I soldered a battery adapter. 9-volt is convenient because you can just clip it on to turn it on.
At the bent end, I glued a grain of wheat bulb. I used a 12 volt lamp with wire leads. Using it with a 9-volt battery will help it last forever.
The main down-side is you have to use it in a dark room. Works for me!
