10-ounce CO2 refill

[Woodfin]

Tell me about your equipment and procedure when refilling your 10-ounce CO2 from a mother bottle.

[Mike Pearson]

I use compressed air for my shifter. I pump up the bottle with my hand held Ryobi tire inflator. Easy and simple

Larry,
I used to get Red Ball welding supply to fill mine. It was so cheap..
If they have a local office near you.
If you have a mother bottle try Freezing your 10 oz bottle. Might help suck it in when you connect it to the mother bottle.

Empty the small bottle and close the valve. Weight it to the ounce and make note. Put it in a freezer for awhile. Hours if you have the time.

Pull it out, hook it up, open both valves, give it a few shakes, close the valves after 20 seconds or so. Weight it again. It will likely be overfull. Bleed gas off until it weighs just 10oz more than when you started or less

Do NOT leave it overfill. It will over pressurize when it warms up and bad things will happen. At a minimum it will pop the safety disc and scare the s### out of you.

Equipment is nothing more than a couple of bottle nipples with 6AN adapters and a length of Teflon AN hose with -6 ends.

Larry the best procedure for refilling them is not refilling them my advice is to install an on board air compressor...

got one installed in both of my cars, makes everything air actuated easy peasy and allows you to air your tires in the lanes.

I had a 20lb steel mother bottle with braided stainless lines and 2 ball valves. I made up that setup after the local paint ball store closed and I got tired of chasing bottle refills....

I could fill a 10 oz bottle in less than a minute and never weighed the 10oz bottle. I had 3 bottles but a full bottle lasted many many runs.....air shifter and throttle stop...
I checked the pressure after a quick refill and always looked when it was hot out and never saw over 1500lbs pressure......so as not to blow out a 2000lb safety disc.
I just bought a car I used to own and added an air shifter to it since it's a 3 speed and I've been racing some 1/8th mile bracket races
Since I gave away my refill setup, this time I bought a K&R on board compressor. It works well....

What shifter are you using the K&R setup with?
