<p>Hi Tom,</p>
<pre>> A non-threaded shaft is never going to be tight in the first place, is it?</pre>
<pre>> <span style="text-decoration: underline;">As long as the hole that that the encoder goes through is a nice tight fit</span>..<br /><br />That's exactly the problem with MANY cheapo mixers that have too large holes</pre>
<pre>for the pot's shaft and these shafts are rocked in all the way</pre>
<pre>with no secure mecanical provision.. Even with a brand new console</pre>
<pre>you can 'feel' the loose the shafts have in their non supporting holes.</pre>
<pre>Sometimes companies like Fender (to name one) use small plastic</pre>
<pre>washers to fill the holes circular gaps for tightening the shafts in place.</pre>
<pre>These pots or encoders are too often used with too much of their shaft</pre>
<pre>going outside the metal front panel causing the premature mecanical</pre>
<pre>degradation. Try to imagine.. when you need to pull their knobs for repair</pre>
<pre>you fear of ripping these shaft out of the device..</pre>

<pre>+1 agree. This is a classic microcontroller job.
JP, what do you mean that these non-threaded shafts "get loose over time"? A non-threaded shaft is never going to be tight in the first place, is it? 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?
Thanks,
Tom
