Well I make a washtub bass for kids using a large coffee can, a stick and some heavy string. I make flutes out of PVC pipe. Everyone does that. I make what I call a foot harp out of a slab of hard wood with zither pins drilled in. Tune it pentatonic like and let the kids go. Ah, drums, I make them out of hollowed elm and cottonwood. Rawhide on each end and rawhide cut into laces to hold them together. Then there's those limberjacks, limberhorses, limberspiders, limbercentipedes.....Rex
