Subject: Hole size standards

From: "Richard Brewster" <pugix@...>

Since we started the standards, topic, how about hole sizes?
 
On my custom panels I used 3/8 (0.3750) inch holes for both the jacks and the pots, and 1/4 inch for the switches.  When I measured some MOTM panel jack and pot holes, they were a tad smaller than 3/8.  I asked Larry Hendry about it and he said that MOTM does make those holes 3/8 inch.  And 1/4 inch for the switch holes.  The paint slightly reduces the measured size.  You may notice when installing a jack, that it is a tight fit.
 
The corner mounting holes are 3/16 inch (0.1875).
 
The standard MOTM Lumex LED goes in a 5/16" hole.  For my MOTM-OMS-820 I decided to use regular LEDs, so I made the LED holes 1/4" in size.  Since we are going for MOTM standards, we might want to agree on the Lumex part and hole size.  Another approach would be to make all LED holes 1/4" and let people who want to use the Lumex part just drill them out.
 
Your thoughts?  Opinions?
