The metal is a bent and curved aluminum yardstick that was cut down and screwed the the wood block. Both were painted with exterior spray paint. Small felt pads on the bottom of the wood help it slide easily and not scratch the desk. The angle is also good for using the buttons; the hand easily reaches around to the metal for back support as the buttons are pushed.
This little stand could be used for a number of smaller rigs and it is very stable. A modification could be constructed to hold a speaker mic - I may work on that in the future.
(By the way, this is a really fun little rig.)
Thanks for taking a look.
