Pot hole sizes - a neat trick for mounting Alpha pots

2009-03-17 by Richard Brewster

Standard pot and jack holes are 0.3750 (3/8) inches in diameter (9.53 
mm).  What if some people want to use large bushing pots and others want 
small bushing pots, like the Alpha?  No need to worry about hole sizes.  
I learned this trick from Larry Hendry (R.I.P.).  Fit a #5 rubber O-ring 
to the Alpha pot bushing and it neatly fills the gap and fits snugly 
into a 1/8-inch thick panel.  The #5 O-ring is a standard plumbing item, 
easily found at hardware stores, at least in the U.S..  I never worry 
about mounting Alpha pots, as long as I have a box of #5 O-rings, which 
I buy from Lowes.  I use 3/8-inch holes universally for pots.  If I 
change my mind and want to replace an Alpha pot with one with a larger 
bushing, it's a snap.

God Bless Larry!
I've been looking for a simple solution to the pot bushing problem for some time - I've done tricks with epoxy, brass split rings, thin washers, you name it.  I've even thought of grommets (too thick). And I never once thought of something as simple as that.
