[SML] Building custom DMX relay box

[Jerry Durand]

Drilling holes like that are one of the prime reasons we eventually got 
a mill/drill machine.  An overgrown drill press with a precision table.  
Then for plastic panels we went to tabletop CNC machines, first MaxNC 
and then cheap Chinese bed routers.  Now we have a CNC bed router and a 
larger floor standing mill/drill with digital readouts.  Luxury!

We used to sell stuff like this, but can't sell to you guys in the west 
now, so I'm sorry to say we can't help.
