I should have mentioned that I purchase this cornet for $50 as an "experimental" horn. My intention of course is not to destroy it, however in terms of slotting, bracing and all that fun stuff I'm not overly concerned. I'm simply interested in trying my hand a horn modification.
Chet Fan: Good point. I'll likely pick up a small duffle bag and stuff it with soft material
Again, this is not meant to be a primary horn. Simply something to pull out for a song or two as an eye catcher at a gig.
Thanks for all the help!
