Does anyone know of a good super glue that will work good on vintage Marshall knobs that are cracked?

I've always been careful tightening them over the years but I've noticed quite a few of my vintage Marshall knobs are cracked.

I intend to install them on a donor pot shaft and glue squirt some glue into the cracks and then remove them off the shaft and hopefully that will repair them.

Is there a good glue that doesn't make a mess after application. I'd rather use something I know works good than do the trial an error thing.:2thumbsup:

Super Glue GEL at the Dollar store in the little application bottles. Make sure it's the Gel. It's clear. I have used it for a ton of stuff. Sands down well with 1000 grit sandpaper if you ever need to as well.

So far I've read of people filling the open voids around the knob shaft hole with JB weld epoxy that way it doesn't allow the bore hole of the knob to expand any longer...........

I know polyurethane adhesive hols well but it usually reacts with ambient moisture in the air to cure and tends to expand outside of the repair joint when it does.

I figured there had to be something newer that will bond this bakelite material by now????

Yeah, if you are worried about the value of them possibly... maybe there is someone that can restore them.
 
I have an '82 4104 with some internal cracking on the knobs and I figured I'd use some JB PlasticWeld to fix 'em up since it won't be showing and seems to work pretty well. It's been holding the mirror adjustment knob onto the shaft in the family care so far. I'll update how that goes.

Edit: a quick search shows that others seem to have had success using JB Weld on bakelite for other stuff.
