• Guys, we've spent considerable money converting the Les Paul Forum to this new XenForo platform, and we have ongoing monthly operating expenses. THE "DONATIONS" TAB IS NOW WORKING, AND WE WOULD APPRECIATE ANY DONATIONS YOU CAN MAKE TO KEEP THE LES PAUL FORUM GOING! Thank you!

What's the quick fix for Volume and Tone knobs that constantly fall off?

Geez, what a nusance. It's a problem on about three of my Les Pauls right now; not to mention the football switch on one of my Strats p/u selector.
I know there's a simple fix before I make the problem worse.
Thanks

If the pots are split shaft, and they should be on a Lester, just gently pry the two halves of the shaft apart. I've also used RTV or rubber cement on occasion.

Although I haven't tried it, you could probably take some teflon tape and wrap it around the shaft before you put the knob on.

I have and teflon tape works great. Be careful with those split shafts, they can break if too much force is used.

What I do - is take a tooth pick... and coat the inside of the knob's hole with superglue.

DO NOT BE A DUMBASS AND PUT THE KNOB BACK ON BEFORE THE GLUE HAS DRIED COMPLETELY.


The superglue builds up material, makes the knob fit "like new". If you can SMELL teh superglue its not dry yet!!!

Sometimes ya need two or even three "coats", but it works fine, is clear, is a completely invisible fix. But it takes longer - you gotta let that knob set up overnight... or more for extra coats. But then again, you dont risk breaking a split shaft either.

Wrap some tinfoil around the shaft of the pot. works like a charm.

Don't try to pry the split shaft apart. It breaks really easily. Just put a small piece of masking tape on the shaft and stick the knob back on.

Thanks one and all. The reason I asked is that many years ago, a teenager, I had the same problem, and yes split and broke the shaft.

Sounds like a lot of good ideas here but I've got one more easy one. I've fixed loose knobs by placing a small square of thin paper over the top of the pot shaft. The square of paper should be smaller than the diameter of the knob. Then I just push the knob on the shaft with the paper in between. It sort of forms the paper around the shaft for a tight fit. And best of all it's temporary but holds the knobs on snug.

Or you might accidently glue your nostrils together. That would be embarassing.

What are you guys using to open up the split shaft a pry-bar!?!?

I've, over 25 years, NEVER broken a split shaft put. You take a small flat head screw driver and GENTLY open up the shaft a TINY bit. It takes VERY little to get the shaft to the right size for the knob.

Use the shaft for what it was designed for.....it is split for a reason! I'd never put gunk, tape, crap in the pot just to get it to fit!

Open up the shaft.

It really depends on the composition of the metal of the pot's shaft. Can anyone comment the split shaft alloy of the various brands? Pot metal will fail without much coersion. Break a shaft and your simple project just became much more involved.
