_Two sizes of bodhran are offered: 16-inch and 18-inch diameter. The skin is normally premier quality goatskin, but calfskin (vellum) can be supplied on special order.
The shell is a poplar laminate of a 5/16-inch wall thickness, with a birch veneer outer surface. The inner surface is painted green, while the outer is stained golden oak. Plus, the shell is re-inforced under the goatskin by another laminate ring.
All instruments have one fixed maple strut (½-inch thick by 1½-inch wide), and it is stained to match the shell. If required, a removable strut can be installed.
