I plan to make just such a pneumatics. There won't be much of a rock, 20-40 atm, depending on the diameter of the pump rod. Perhaps the pump handle will play the role of fits. I know that this is not the most effective scheme, but it must be done.

Ideas about a two-stage compression pump with a force lever would be useful ... :roll:

If you have to pull to pressurize, it's really not comfortable at all. For a pump you want to be pushing against a hard surface, especially if you don't have the benefit of a lever.

Slightly related, have a look at clide's minipump. Here's a cool flash animation he made, click on the commands in the top right of the screen to go through the steps.

I could not see the animation. It seems that I'm going to have to unsubscribe this old PC ... :oops: The article with photos, I like it. Interesting construction. :)
