i noticed a post below that listed a link to a company that sells material to make your own friction calls. this sounds like something that i would be interested in doing to pass the last couple winter months by. does anyone have much experience making their own calls?
what combinations produce what sounds?
does the pot make the call or the material(slate, glass etc.)?
how about the strikers?

any insight would be greatly appreciated, along with other sites that sell the components.....thanks squid
