Re-use of Rubber Bands?
I've done the talcum powder thing, but I actually liked storing them in alcohol, better.
(yes, regular rubbing alcohol, and I'd change it when it got "oily")
Most of my stuff is bolt-on wing now, or "one-piece", so it doesn't affect me either way.
Still... I used to reuse them for several sessions, when all my wings were banded.
NO, they don't cost much, but I never got used to the idea of throwing
them away, when they were still in perfect shape... but that's just me.
Once you're accustomed to the bands, you know how they feel, once they're getting
weak. You know how far they should stretch, how tight it should feel at the end, etc...
As long as they passed the stretch test, and as long as there were NO nicks
along the edges, I reused them. Can't say I've ever had one break, honestly.
I certainly have never lost a plane because of re-using rubber bands.
