You could take the donations a step further and make it a lottery with any excess funds, pay your $5-$10 whatever it is. Have Y block motor parts as the prizes,tappets, tappet covers, push rods, valve springs, etc, etc,
Being a global thing the prize winner would have to pay the freight to claim his/her prize, if not the prize goes back into the kitty for next time.
