You are correct. It is by far better to have the correct component from the start. The high pressure hydraulic systems I am responsible for are bad enough. Pneumatics are a whole new level of scary. On reflection it is not a good idea for the average person to play with the inner workings of a valve system.
Unfortunately, the majority of T-shirt launchers are not based on well engineered designs. They seem to be based on you-tube videos and the desire to shoot things. Thankfully most of us who have managed to make it to adulthood have managed to suppress the urges that led us to playing with fireworks, slingshots, pea shooters and home made darts.
Although, I have to admit I still have some of that garage inventor in my blood... must resist the urge...
To those who will be making T-shirt launchers: They are inherently dangerous. Please o' please if you are doing this stay conservative (high pressure ratings for lower pressure applications)!
