Freezing the balancer may not be a good idea IF you're going to use a lock tight product. Putting it in the fridge would work if you heat the ring. When u pull a metal object out of the freezer into the normal atmosphere you will immediately get condensate (moisture) on the balancer. Lock tite is water soluble so when you try to put lock tite on the balancer it will dilute and not work as intended. This will happen to a much lesser degree if you just put the balancer in the fridge.
The only reason I know is that in the aircraft industry we used freezing and heat to mate many objects (using lock tite) until it was discovered that lock tite is water soluble. Even in the air conditioned environment we worked in the parts would start sweating as soon as we removed them from the dry ice freezer. As it turns out, once you dilute lock tite with water it loses all it's bonding properties. We had to increase the heat on the ring or cylinder to get them to expand enough to compensate for not freezing the mating parts.
