Subject: Re: [ModularSynthPanels] Another take on small pots in MOTM format

Andrew, your 2U Doomsday Machine panel is chock full! You've taken the
idea of panel density to the max. Jacks can certainly be closer
together than MOTM. A 7/8-inch vertical jack spacing makes for a square
jacks grid like Modcan B. What type of pots did you use? Those look
like Blacet knobs.

I tested with knobs taken off the Encore UEG, which uses a 7/8-inch
vertical spacing between pots. The pot grid on the experimental panels
is 1-inch vertical spacing and 7/8-inch horizontal, the same as the
standard MOTM jack spacing. The knobs fit fine and there is enough
vertical clearance between them to place a standard label. I put the
labels above the pots and placed the top row as close as possible to the
top of the panel while leaving room for the pot behind and the label in
front. I am not sure if there is room for eight 1-inch spaced positions
bottom to top; the top pot seems to come too close and there isn't much
room for a label above. Labels could be moved below. I'm going to
experiment more by making a mock panel of cardboard and checking the fit.

And you are making me re-think the idea of a 7/8-inch square grid all
the way! But there is still the advantage with 1-inch vertical spacing
that a Bridechamber 3-jack bracket can be used. In fact, this is what I
think will work to mount the CGS Super Psycho Modulation Source PC board.

And that begs the question: How did you mount PC boards to your
Doomsday Machine panel?
