I am considering adding temple blocks to my orchestrion.  They are
available on the Web, at quite a cost as they usually come in sets
of five.

Does anyone have any for sale, and is there a book on how to make
them and what wood to use?  There are about three types: one is
a cone-shaped cylinder, ones with flat sides, and the ones I prefer
are the round/oval type.
