How to make rubber contract or shrink
June 12, 2009 3:00 PM Subscribe
I have a set of rare rubber-grip Stratocaster knobs taken from a 30-year-old guitar. They look very similar to these
. Problem is, the rubber grips have stretched out and are no longer tight around the knob. Is there any way to make rubber contract or shrink slightly so the grips fit correctly?

These knobs are unique to the Fender Elite Stratocaster, which was only made for a few years in the early '80s. Two of the three knobs have loose rubber grips. They are not in danger of sliding off, but they feel loose every time you use them, and it's very annoying.
Anyway, I am wondering if there is any way to get rubber to shrink. Would heat do it, either by flame or boiling or something (keeping in mind that it's 27-year-old rubber)? Or am I out of luck, and what's stretched is stretched?
