You can get by with hardware store dowels. Try 13/32 or 3/8 for ramin wood(normal dowels). Sometimes you can get oak dowels. Get 3/8 and they will shoot great. I do suggest buying some shafts to start, of maybe spruce, ash, or fir, so you know the approx stiffness required to make good arrows. Feathers can be bought, precut or raw, or traded for.
