[sdiy] Front panel design philosophies

[Declare Update]

I'd have to agree that anything closer than 15mm (I use 0.6 inches) is pushing it. 0.6 works great with the various vertical mount jacks I've tried, and keeps patching comfy. I do the whole layout on a 0.6" grid, with pots usually double that. if you use small knobs like davies, pots can go 0.6" from each other too, so long as there is space on the sides to turn them. This allows 7 elements vertically, often 2 pots and 6-8 jacks per 6hp, and I never go under 6hp.
