I'm suddenly vary aware of how much more respect and praise I should be hoisting on my buddy who printed my print and play Lindsay system chanter for me.
Suggest you get a Dilrin loaner set for your students to use for paid gigs. 4 to 6 gigs should raise enough money to get an all weather Delrin set. ABW set to follow. A piper could have 2 sets going inside of a year. Bands may have used sets for sale as on trades up. Good luck and pipe on.
