MOTM

Hello! there is NO GAP.
The MOTM rows butt up bottom-to-top edges with no gap at all! The
center-to-center hole
spacing is set up specifically not to gap.

Now, what the poster wants to do brings new meaning to the term "wing
cabinet"! Maybe more like
'flying wing cabinet' :)

Be aware of 2 things:

a) the holes are 8-32 tapped NOT 10-32 which "standerd" rail stock uses
b) the rails MUST be no more than 0.500" wide, or you will hit the top row
of pots
(or the bottom row of jacks!)
