i've been thinking about this for a while, and i knew i could get some help here, im planning on constructing it out of some thick @$$ plastic pipe, i m going to make lugs and try to get some sort of head system, but the thing thats bothering me is how im going to make the heads... i know i can order them, but it seems like a whole lot of money for that dinky little head... also, i wanted to know the dimensions of standard octabons if anyone knew.

thanks!

is that 6 for all, just vary the depth for different tone?  Or can i get a different sound from a different diameter?
