Wrong..

See some of the following pictures that show my MIDItoCV module fabrication:
http://www.arcenson.com/projects/Modular/M100_MIDI_Interface/Module_pictures
/
All the mechanical building process is shown..

And in these 2 pictures:

You'll notice that.. yes one of the flange hold the complete PCB,
But the metal plate underneath the PCB with the 4 holding screws
Is NOT part of the frontplate metal piece.. There are 2 flat head 6-32
screws
Holding the PCB metal backplate to one of the metal frontplate flange.
Easy to construct.. The only thing to be aware is to make both flat screw's
holes
deep enough so there are no screws that exceed the frontpanel final width.
Solid, reliable and keep construction from getting holes in the front panel
design.
All the above pictures show the process with details.

My Moog 904C Filter Coupler clone is finished now.
I'm also finishing my 904B High Pass filter clone.
If anybody want some pictures when done I'll publish them.

The flanges are for stiffness. Without them, you'd need 3 mm thick aluminium
(like MOTM), not 1.5 mm as here.

One of the flanges can also hold the PCB. Removes the need for a bracket but
makes fabrication more difficult if you don't have a notching machine. You
have to cut perhaps 30 cm of metal and you cannot use a shear. I wonder how
Jean-Pierre does it.

Interesting decision to duplicate the original panel design.
Those 3 knobs and 5 jacks would easily fit in half the space.
Very north american. :->
