I use a 2 part epoxy. Just look in the adhesive department of
a home improvement store, should be next to the super glue.
I think it is made by devcon or something like that.
It will have 2 tubes, one with a white cap and one with a black cap.
Just mix equal parts and apply. It should only be a couple bucks.
I even used this stuff to repair a broken pot shaft on a receiver.
To this day, I can't tell it was ever borken.
