Well...I've been looking into building a nitrogen system in the garage for recharging shocks.

Looks like I can take the traditional route and go with the welding supply unit, (tank, regulator, etc) or possibly use one of the paintball systems.

I think I'm going to go with a paintball unit with custom hose. A lot more portable and less industrial.

Thoughts? Ideas?


I have a thought AND a question. First, safety should be the most important factor in desgining such a setup. These are high pressure systems and people have been killed by projectiles when pressure is released unexpectedly.

Second; does it matter what type of nitrogen is used? Medical or industrial grade?

When you get done, I hope you'll share your setup here with pics.

hey dave..i see you in campbell..i'm at want to get a ride goning ?

Yea...that'd be cool.

My bike is in science project mod at the moment, but I should have it completed by next week.

Been doing mostly track stuff. What do you prefer?

If I get this thing together I may head up to ClubMoto for some testing. Ever been?


BTW - I'm close. Near John D. Morgan park (Winch/Campbell).

I never thought about a paintball set up. I just wonder how much they are. I screwed around trying to make a welding rig work. The size of the fitting on the nitrogen tank is different than oxygen or acetylene. I pieced one regulator together, screwed around with it trying to get it to work well and finally just bought the set up complete from Race Tech, and then had a super mondo, high zoot, deluxe hose made for $15 at the local hydraulic hose shop.

Industrial grade nitrogen can be used.

o forstrokes is my home handle..this is work


One of my nitro bottles came from a local gas supply company. They sold me a used 57# bottle with a 3 year certification for 60.00, filled.

He also sold a an adapter to use an oxygen gauge for 5.00.

The price on all new equiptment was about 450.00!!

It pays to call around.

Take care, John

I have a setup that Kent Moore sold. Instead of a regulator, it has the two gauges arranged with a large needle valve. It is fast and easy to manipulate the pressure.

On the business end of the hose I have put an open minature quick coupling. My inflators then plug right in for quick change of the various adapters.PT
