Thanks

How thick is it

[@Reverend_Mojo]

The proper thickness to make that pitch when spun!
Seriously though, My bullroarers go from very thin, to rather thick.
I find the edge geometry and relative proportions more important than any specific ratios

Nice. Maybe the aborigines heard you. It would be even better if they answered you back

[@Reverend_Mojo]

A passing child yodeled at me after I spun it, that's almost as good.
