I have a Copley and Boegli blackwood flute.
It breaks down to three pieces. The connection at the top (between the B hole and the embouchure hole) has always been a little tight. Because of this I try to keep it well lubricated with cork grease.
Last night after playing, I notices that a small area, a couple of millimeters, of the cork had been scraped off and the wood was showing through.
Has this ever happened to anyone? Is this an issue? Should I get it repaired immediately? I certainly don’t want to continue scraping more and more of the cork off.
