[sdiy] building m7 up to 5/8

[Jason Proctor]

well, i messed up again and bought a crapload of Alpha pots with m7 
mounting holes, even though the panels they're going into have the 
regular Bourns/Spectrol/etc size hole.

ISTR some sneaky "neoprene washer" method of building up the shaft (ooer) ?

if this is a janky solution or whatever i'll just send them back and 
try to find some with the right hole. i suppose it's not too bad 
given only 2 panels have the big holes.

thanks in advance
