Question regarding loose knob cover

Hey everyone,

Lurked here for a while before finally registering. Great site. Lot of knowlege delivered clearly and often quite humorously.

Anyway, I have a question about a simple repair. The knob cover, not the knob itself, for my speaker selector knob on my Onkyo receiver came off completely. The knob itself is fine and continues to function.

It seems an easy glue job, but does anyone have a specific glue or epoxy recommendation? Would krazy glue do the job?

Much thanks.

I've never done this particular job Jack, but I've had little luck with Krazy Glue if the two mating surfaces are not dead flat, and super clean. I have much better luck with a 2 part epoxy. Of course then you can get into trouble with epoxy generated heat, it's generally not a problem unless one or both of the surfaces is too sensitive to the moderate heat an epoxy creates. I'd wait until you get enough repsonses to average an solid answer out of the bunch. Heck there's every likelyhood somebody here has fixed the very same problem.

Good luck!
 
Unlike the thin "Krazy Glue", the 'medium' or 'thick' cyanoacrylate (CA) glues will fill gaps and are very strong. These are widely used in hobby applications (e.g., R/C planes) and available from places like Tower Hobbies. Excellent glues.

I'd probably use medium CA, or epoxy, or even good ol' Duco cement. Sometimes, I like to start with the easiest, most friendly glues, and work up to the serious stuff if and only if needed. Depends upon the job.

Hope this is helpful!
 
The two I use the most "either will work"

Take a wet paper towel and smear the inside of the knob cover, then put a "small" blob of Gorilla Glue on the tip of the knob liner. Push them together, being careful to properly align the liner with the cover (I would mount the knob liner on its shaft, then push the cover in place. Works better unless you have a 3rd hand).

This glue will activate by the light amount of moisture left in the cover and will tend to foam up a bit, so you will need to carefully clamp or weight the two parts in place, or they will tend to be pushed back apart somewhat (too much glue will be bad in this respect).

You should get a truly excellent bond that you will not need to worry about again. Be sparing in your glue application. A little goes a long way, and too much will foam and push back and squeeze out.

Gorilla glue is a urethane glue, and will be permanent, how ever it sets up. It will allow for some workability (realignment, etc.) whereas, a cyanoacrylate (super glue) will be totally unforgiving, IF it sticks in this case.

Be careful...
