<br>
If you want to machine a prototype then a drawing would be helpful...<br>
You can find it here:<br>

<div>
<div>That's what I've been looking for! Thank you!<br>
</div>
<div>I was almost ready to machine those myself...<br>
</div>
<div>Although I'd rather have one for 1/8'' shaft or 4mm, have you seen them anywhere?<br>

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

<pre>+1 agree. This is a classic microcontroller job.<br></pre>
<pre> <br></pre>
<pre>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?<br></pre>
