I fixed my flute!

The Eb key on my flute was stuck, it wouldn't spring back. Also the spring was on the wrong side of the pillar. I corrected that but it was still stiff.
All it took was lubrication. I had no oil per se but we had a little tub of olive oil from my daughter's cooking class. I took a very fine needle and just carefully applied a few drops. Capillary action drew it in, and the key now springs back.
