Hiya Gavin,
Would you have a link or something so I can have a look at a beta drum please?
I'm assuming that it's along the same lines as a Thompson but I don't know for sure!
Would you mind also, please, sending me your e-mail address (by PM) as it might be easier sending drawings etc that way.
Mind you, if it works, I'll be glad to post it on here.
Cerwyn
