Triton Ivory III and the rotary 4 position knob slips unless it is pressed really hard. It is a simple sleeve with a flat on it to engage on the plastic shaft which seems to turn fairly readily with just finger power. Nothing seems particularly worn but obviously is.
What is the best way to pad it out? Paper? Aluminium foil? Glue and let it set? Other?
Oh - just looked at it in a better light and it's got a split.
Still same question as to repair - araldite?
I was going to say buy a new knob, you can find such stuff online but it lo oks like you'd need a whole front cover for about £35
Maybe some epoxy putty with care but make sure you don't glue the front to the shaft or you'll never get it apart again!
I bound some wire round mine and that's still working OK. I.e. I wound some wire tightly round the plastic collar part of the knob so that it couldn't spread.
Yes it looks as if some collar of some sort is the answer. I've got some garden wire - did you go for something thick or thin?
Even a small jubilee clip might work if I could find one to fit.

A few turns of soft iron wire (or copper), not too thick, in a single layer would be easiest to apply. Twist the ends and give it a light coat of epoxy glue over the top to keep it all in place.
The forces concerned aren't too great so no need to go overboard.
Come to think of it I might have used a tiny jubilee clip, the sort of one that comes in an assortment that you think you'll never find a use for! :-)
I was thinking of plain tinned copper wire as that's quite easy to wind tight in such a situation.
A slight improvement is to use enamelled copper wire as it's protected from the elements. But, yes, this will make a good strong repair.
(I have IIRC a 10km reel of Swingfire missile control wire which is four steel cores, copper plated, enamelled and overall cotton covered. This would work well too. I bought it many years ago on a whim and must have used several feet already!)
Cheers
Yep, I've yet to find a glue that has enough strength in tension to work for long in this application. As fred says, bind tightly just two maybe three turns, twist ends together to tighten the binding and coating of goo to hold it in place and give a bit of protection.

For more awkward situations where wire wont work or for higher forces, I have mixed up some glass filled epoxy filler (eg Isopon P40) and packed out the cavity with that. Carefully putting the knob over the shaft before the filler sets to make sure it well go on.
New knob? I glued one once and two weeks later half the knob fell off as there must have been a crack in it somewhere. Brian
car body filler is a great gap filler that doesn't stick to (most) plastics
