MPC REN knobs keep falling off

Anyone got any ideas on how to keep these knobs on?

I've taken mine on the road twice now..(its a decent magma road case made for the ren) somewhere along the line the master volume knob disappeared... and every time i open up my road case one of the qlink knobs is floating around.

There doesn't really seem to be much holding these things on.. some of them slide off super easy. was wondering if anyone has any good methods of keeping these suckers on?

Have not tried it myself, but maybe a small piece of the thin white teflon tape that plumbers use, over the top of the shaft, before you push the knob down onto it, might work.

would super glue void your warranty? Being able to take the knobs on and off is required for taking the case apart in case of any required repair.. I'd try some tape like simon suggested to get it really tight and snug but not adhered...

made , for what you need it....

Yep, Loctite will do it, just use the weakest one you can find, so that you can get it off later when you need to.

@Loctite i linked not a glue, it is a "thread locker" .... the difference is, how to get it off again

It is actually a glue, just made so that you can undo it later.

There are different strengths available, that require different amounts of force to break the glue, I am just suggesting to get the weakest version you can, so that it is easy to remove later without breaking the pot/knob.

Also, Loctite Threadlocker is normally used on metal threads/fasteners, not plastic parts, not sure if it will affect the plastic in the knob or on the shaft.

From the link you provided...

Not Recommended For

Use on plastic parts, particularly thermoplastic materials where stress cracking of the plastic could result

If using Loctite Threadlocker, I would probably try to find the 222 version of it, which from this chart, has the lowest strength...

Thanks guys.. that threadlocker looks like the joint.

my main concern was not wanting to break those qlink knobs so that the tops were no longer touch sensitive.

Touch sensitivity is a good point, are the pot shafts, and knob internals, metal then?

Tape would probably stop that from working.

If using a threadlocker, maybe a very small amount would work, just on a lower side of the shaft, so that there is still conductivity through the pot shaft to the knob?

@simon
i just wanted to "underline" that i didn`t mean superglue, because many people are thinking first of superglue when they hear or read "loctite".

you can try stuffing it with paper too a bit like that when you press it down it will be nice and tight around the shaft ;p and stay on with out having to use taper/glue
