I recently took the pressure chamber casing off my CPS 2100 to expand its capacity, which also enables you to see how much is in the chamber. I'm wondering if this has been done before, and why everyone doesn't do it, because it seems rather obvious and simple. And all my friends are amused at a water gun with a "Balloon" for a pressure chamber.

Letting the rubber expand more than the conventional limit can weaken it over time. In constant pressure homemade water guns, we're free to let the rubber expand a full 8x in diameter, because latex rubber tubing is cheap and the bladder is easy to replace. That doesn't hold true for commercial water guns, especially CPS ones (which become rarer and rarer with time).

True. But if that happens k-modding becomes an option.

Has anyone looked into melting LRT and molding it into a spherical PC?

Removing the casing also makes it more prone to getting scratched, which, over time, even small scratches may develop into tearing which eventually breaks the PC.

Melting... None of us (that I know) have the equiptment to do that with the precision to create a spherical PC that's perfectly even.

Melting would indeed be rather difficult. At any practical temperature, you'd probably end up with a rather sticky, gooey substance. For example, in auto racing, tires partially melt due to friction with the road. I'm not sure what temperatures they reach, but it's rather high and you still only end up with viscous glue.

Keep in mind race tires are designed not to melt though. Because LRT expands easily I would think the interactive forces between the molecules are easier to break, making it easier to melt.

That's true. I don't know if they use any real rubber at all. But still, it would be hard to determine the melting point based solely on the elasticity of rubber. We don't even know the basic elements in LRT! (Although we could easily find out.)

I'm not sure if melting LRT down is the best idea. The rubber itself might not melt down and cool off into the same material. If you can make latex molds it would make most sense (and cost less money) to just buy the rubber material directly and mold from what. I've researched liquid latex before and that seems plausible. I don't know anything about how latex tubing is made though. Try researching the process. I'd do it... but I'm pretty busy for the next two weeks. Maybe I'll look into it more closely after that.
