[sdiy] Avoiding Ground Loops on Panels

[Scott Stites]

Hi List,

I've been building panels for my synth using un-anodized aluminum stock.  I plan
to put the legends onto the panels much in the same way that Ray Wilson did with
his mini-synth, IE laminating paper labels onto them as shown here:

The connectors I'm using, 3.5 mm, will still ground to the back of the panel,
which to me means that I'm just asking for ground loops.  I thought about DIY
anodizing, but stopped reading pretty soon into it when it mentioned the vat of
sulphuric acid that I'd need.

So - how does one fully isolate the ground on the connectors from the panel in
this case?  I recall someone mentioning that they used nylon washers.  Where
could I find these washers?  Is there some sticky mylar tape I can get?  Will a
clear coat of laminate isolate the whole panel?  Am I asking too many questions?

Any advice most appreciated,
Cheers,
Scott
