Welcome to the Water Rocket Forum, sponsored by The Water Rocket Achievement World Record Association.

The largest, most sophisticated and ground breaking group supporting you, the serious water rocket flyer! Whether you are a beginner or an expert, the WRA2 has something for everyone.

A water rocket is a type of model rocket using water as its reaction mass. The pressure vessel (the engine of the rocket) is constructed from thin plastic or other non metallic materials (usually a used plastic soft drink bottle) weighing 1,500 grams or less. The water is forced out by compressed air. It is an example of Newton's third law of motion.

600 psi shock pump

Post by RaZias » Thu Jun 03, 2010 6:17 am

This pump is a small pump to pressurise a shock suspension for Mountain bikes.

The catch is that works with the wrists but I wonder if someone could adapt it to a structure to work like a feet pump system...and then adapt that system so that instead of putting our weight with the feet we could put our body weight like a 2 hands system...

If you had several of them working in parallel, you could overcome the small volume of the pump. The other thing to remember is that getting 300PSI from a 600PSI pump would be quite effortless, so if all you need is 200 or 300 PSI then this could be a good choice for you.

It´s also necessary to say that this type of pump doesn´t (i think) connect to a typical tire valve but to a special valve in rear shock for bikes so you have make a adaption...

i noticed that the pressure chamber is verry small,and you could get 600 psi with only your arms, i wonder if making a pump out of 1/2" plumbing parts would give the same ammount of pressure with less effort.
