That's exactly the problem with MANY cheapo mixers that have too large
for the pot's shaft and these shafts are rocked in all the way
with no secure mecanical provision.. Even with a brand new console
you can 'feel' the loose the shafts have in their non supporting holes.
Sometimes companies like Fender (to name one) use small plastic
washers to fill the holes circular gaps for tightening the shafts in
These pots or encoders are too often used with too much of their shaft
going outside the metal front panel causing the premature mecanical
degradation. Try to imagine.. when you need to pull their knobs for
you fear of ripping these shaft out of the device..

As long as the hole that that the encoder goes through is a nice tight fit, I don't see a particular problem (assuming the PCB is well supported). So what am I missing?
