co2 regulators for small cartridges

I saw this on a biking website and wondered if this is something that could be modified to work for smaller boats that are very weight sensitive.

What would have to be modified and would an expansion chamber be needed to get the pressure correct?

 

Those will not work for even small boats. They provide a direct vent into the Co2 bottle with no built in regulation, so you're getting around 800 psi from the output.

 

That could be a problem then. Would it be worth putting in some kind of regulator or at that point am I gaining to much weight? Is it because the ones for the bikes don't have anything to reduce the pressure of just that design?

 

You will need a regulator. Those cheap bike tire inflators do not regulate pressure, only reduce the flow rate of the CO2. There's only three lightweight regs (that I'm aware of) in use with dd's. The Palmer Pursuit rock the boat reg, the Genuine Innovations composite reg (what I use), and whatever Vac-U-Boat is using with the new plastic Fletchers.

 

Check homebrew websites, they like to operate at lower pressures as well.
I would advise anyone to stick to the basics on their first boat and get on the water. The exotics can come later. While we all like talking about ship building and giving advice and watching build daries, the real fun is on the water.
Rule of thumb: Smaller the device, the more money it is going to cost you.

 

I think this is what Vac-U-Boat is using.

 

That looks promising, but I believe they are all chinese so the branding may be different. Use at your own risk...

 

If I was to make a lower body for the ultra light series how much many of you would be intereste.
Any input here?

 

Just make one with an 1/8" NPT port on the bottom for this:

that needs a threaded capsule, correct?

 

I would, this would be great for the destroyers. Make a separate bundle with micro pump, 50 round gun and regulator and capsule.

 

Yep. Of course, BC making a version that could accept the threaded caps directly would be cool but machining the steel piercers might be a pain.

 

was thinking of the cup that would force an unthreaded capsule up into the regulator. Not sure of the availability or cost difference between threaded or not, as well as 12 versus 16.

 

Naw that's easy got to have a good shop

 

I do like the 1/8npt variant though it allows for a broader use platform easy to make attachments 1/2-20, 3/8-24 etc....

 

Something like this, Steve? https://palmers-pursuit-shop.myshop.../3-8x24-to-825x14-adapter?variant=12133035335

 

I prefer the 16g for battle. It leaves a nice reserve. In my testing, 12g will just make 50 rounds through my Mog's cannon, and that's with careful triggering on the bench.

 

Yep, or the ole 12g paintball adapter like we used back in the 80's.

This is a fancy one.

If you mean make something so that I can just thread in a 16g co2 cartridge, I'd probably get a couple of them. Especially if it is the same or less weight than the Palmer's rtb I use now. They are just getting way too expensive.

 

The Current BC reg is 2.4oz this new reg would look to be~2oz and about .625" shorter with an 1/8"NPT input port
