[sdiy] Why I was asking about UNEF etc.

[jhaible at debitel.net]

Thanks to all who answered - I think I have understood this
now.

Why have I been asking?

I have made a little redesign of my 3200 front panel.
The 16mm knobs for the temperament pots were too bulky,
compared to the 21mm knobs I'm using for the pull-pots
of the regular parameters.

Now I found a nice little 11mm knob that matches the
bigger ones - so cute and tiny, and they fit on
a 1/8" shaft of these Bourns 9mm conductive plastic
potentiometers. (Bourns 3310Y) 
And while this _does_ work when I mount the pots with
a nut, the drawback is that I must avoid the knob
to touch this nut. (The knob is larger than the nut,
so it will be covered. But it's not large enough for
nut to dissapear inside the inner hole of the knob's
skirt.)

So I wonder if I could just make a thread into the
aluminium panel and crew the pots in from the rear,
_without_ a nut on the front panel.

I don't know if this will work, becaus ethe pot will
get some rotational force from turning the knob in 
normal use, so I fear I could loosen the pot in the
front panel, if it's just screwd in from the rear.
It _might_ work, because the plastic thread of the pot
might give enough resistance if it's srewd in with enough
force; and I also have locking washers I can use (also
on the back side of the front panel).

Is there any chance this will work?
If it doesn't, I can still apply the nuts from the
front, so I guess I don't take any risk.
But maybe somebody has tried this before and can tell
me if it will work, or if it won't.

(Of course I cannot predict the end position of
the rectangular potentiometer body if I do this,
but this doesn't hurt becaus eth epots are so tiny,
and sealed.)

Any helpful comments ?

JH.
