I built this banjeaurine on a lark and to satisfy my interest in learning to play clawhammer.
The banjeaurine seemed like an obvious choice as it has a shorter scale
length than a typical banjo, similar to a concert scale ukulele, and is
tuned to C. This was my first go using a tin that was not round. I have
avoided using octagonal, rectangular, or other odd shaped tins because
the lids are usually lose on the sides and introduce all sorts of can
rattle noise. In addition, those flat sides are not supported by the
shape. In a round tin the curve of the sides make them stiff. In this
case, as you can see in the first image above, the back side is
supported by what was the top of the tin with a round hole.
