I like this idea...do you use SquishyFeet™ instead of regular pcb standoffs? Where do you get them? |
actually anywhere that sells hardware/small parts both online and locally.
Depending on how much of a gap I need I use either soft rubber grommets,sometimes stacked,or even the chassis feet for small cabinets that have the tiny screw hole in them.
Being made of a soft material you can just "JAM" a larger bolt through the opening if needed.
The cool thing is I can adjust the "cranking pressure' and make the "spring" have a lot or a little play depending on what I am cranking down.
This also makes it easy to level the whole board assembly by selective pressure at the corners (can't have uneven boards !!!!
).
Even exterior chassis feet I usually go for "squishy" and not spikes even though they look cool and are flashy.Throw in a wood block for mounting the assemblies and I have a good "tone" (joke on the "mother of tone" and Audio Consulting sites even though I fully agree with most of the theories)
Quicky story-I tried to make some cool (FREEE !) chassis feet by squirting tub and tile sealer silicon caulk into an ice cube tray but the results were not as good as I had hoped.They looked like pure crap and I could never get all the "feet" to come out the same exact size becasue the filling was never exact so some would be taller than others.
This would not be a problem if I made say,oh I dunno,maybe a
thousand and then sorted to size but jeez ! I only wanted THREE !
So scratch that thought and file it under "never again"
