Re: Help Identify This T-Shirt Cannon Robot Please
You can get a good sized metal air tank for cheap. The T-shirt shooter we built on 498 back in 2007 used a 5-gallon Campbell Hausfeld air tank from Walmart for under $50, and we just filled it with 2 kit-compressors in parallel. Didn't have to be replaced until a year or so ago, when they found some water starting to pool inside it. Since we didn't do any maintenance on it for 6 years I'd say that's a good life span on it.
The barrel on ours is PVC, but unless you jam it shut the odds of the barrel shattering before the t-shirt is dislodged are pretty low.
