This is a quick and dirty design of a tube mount for the Open Pandora Handheld computer (http://en.wikipedia.org/wiki/Pandora_%28console%29 , http://boards.openpandora.org/). I specifically made it to mount on my Electronic drum rack to play music to play when practicing and to take advantage of the various open source Linux MIDI programs that are out there.
On the Clamp portion for mounting hardware I used two 4mm x 0.7 x 50mm hex head screws and 4mm x 0.7 wing nuts.
The mount was glued to the clamp portion using a small amount of Gorilla Glue ( The stuff expands considerable ).
