My Pitts 3rd scale has a pair of stainless steel resturant salt and pepper shakers from Italy but you can find various sizes at Wal-Mart, also check the BBQ section...

Light weight alum. tubing various sizes can be had in wind chime kits for a buck ninety eight in the crafts dept. also, but soldering can be done it may be difficult unless you practice on pop, Soda cans...
