ive used a couple trumpet mouthpeice, a socket from a socket wrench (if thats what its called), one made from a metal pen and one with a metal bottle cap (i know its not good for you, ive only used it a couple times before i know it was bad). making home-mades has been a bit of a hobby for me and the main problem is trying to find somthing for a bowl that wont fuck up your head (or so ive heard, aluminum). can you guys suggest anything that i could use as a bowl?
Get a bowl from a local head shop. You can buy pieces individually and you can reuse them over and over again. I use one for all my home made pieces. Shouldn't be more than $2 I'd say.
