Dry Norfolk Island Pine. No knots but it has nice spalting! No cracks.
I will turn it down to just fit into a MFRB if your interested.
Aprox. 8 1/2" diameter X 5 1/2" tall.
$26
Good solid pine would probably be OK, but if it's spalted and somewhat soft, it'd likely need stabilizing. I'm just not sure how pine would do with stabilization. It's so sappy.
