if anyone wants to try this be careful! dont just fill it with water and leave it for a long period of time. it will bust the tube. only freeze it for a few hours at a time. let the ice melt so it has another starting point to expand.
ill post pictures when im finished.
Sounds like a recipe for disaster.
Why not spend a little $$$ and have it done professionally. The amount of force that freezing water can produce is more than enough to compromise <1mm tubing.
If it is lugged, you can have a tube replaced for a pretty decent price.
