Analogue-sequencer

One for Colin, I expect (predictably...):

I noticed recently that the mount for the Data and Tempo knobs had  
come loose. I assumed that a nut on a mounting peg had come unscrewed  
somehow, so opened the unit up. Nope: the nuts are still in place, but  
one of the pegs has completely broken off the back of the faceplate. I  
have no idea how this happened, since the unit has always been well  
packed for transport and never abused, but I guess at some stage there  
must have been just enough pressure on the Tempo pot to break the peg;  
I have no idea how or when.

So I'm wondering how best to fix it. A replacement faceplate feels  
like total overkill; would it be a bad idea to simply Araldite the peg  
back in place? I like Araldite.

Glue may well hold it.
The shafts are self-clinching fixings, which are pressed in to the
aluminium, so should be tight fit once pushed back in, even though it will
have lost its grip. Possibly even a spot of superglue might hold it in place
quite well.

The reason the later P3s had their pots mounted on the subframes was because
the only pots I could get hold of had shafts that were 20mm long.
Fitting those pots directly to the panel meant the knobs would sit quite far
above the surface - which is how they sit on earlier production P3s.
I think on the second or third run of cases, I had the case factory fit the
mounting studs to hold the subframes in place, so the pots would sit flush
with the panel.
Since those days, I found a source of 15mm shaft Alpha pots.
Fitted directly to the panel, the knobs on those sit almost flush to the
panel.
So for a much more robust repair, you could replace both pots with panel
mounting ones, that will match the height of the other pots on your P3.

Cheers. I'll go for the Araldite solution first - it looks pretty  
trivial to do, and won't need much of the stuff - and if the problem  
recurs I'll look into replacing the pots.
