From Square Shooter. Sure hope you try a small one, from a branch, maybe 3' or so long.
I've never made one, but a model would give a lotta info to us all. Is there anything on
the 'net about em? The same oils that seal a bow wood seal a dugout, seems. I know
they made em real thin, like about 3/8". It must be a big diameter trunk you have. Think
what a 2 × 4 will do. Its soft wood. Seems a model of the same scale thickness wood not
be quite the same scale strength, tho.
