If you're that desperate for air storage use the extrra tube that came with the kit. Last year we figured out it had slightly more volume than one of the supplied reserviors and weighed slightly less. But we didn't have the volume in the robot to make it work.

Do it yourself pressure vessels (what Mr. Harbison was proposing) are a VERY BAD IDEA.

Engineering is the continual exercise of judgement. That includes judgement on when you are getting in over your head. I am a licensed mechanical engineer. In this state that means that I am legally qualified to design and build pressure vessels. BUT because that is not what I normally do, I would never attempt it.

I am just not familiar enough with the design methodology and safety standards to do a good enough job to ensure I don't kill somebody. If I'm over my head on something like this, chances are you are too.

Not only is it against the rules it is just plain STUPID. When you pull something like this you are playing with the eyes, limbs and maybe lives of everyone around the robot. You have created a potential bomb.

Pnuematic components are fabricatred to comply with strict codes to ensure they do not fail under designed use. If they should fail, something is likely to go flying at high velocity. Very few, if any teams have the expertise on board to design their own pnuematic elements in such a way as to conform to industry standards. That is why the use of self designed and constructed pnuematics is prohibited.

DON"T DO THIS

Have we made ourselves clear?
