Re: drink maker brainstorming
@Andrew I can almost picture what you're describing with the PVC/endcap interface but am a little bit dense/new-to-this and might need a diagram to fully grasp. In the short term, I think the current "straws" (not drinking straws, of course, just seemed like an intuitive label for them) are of small...

Re: drink maker brainstorming
Sorry, I was a bit rushed earlier, I kinda figured It would be confusing. Basically, it was a way to make your picture work. I know for a fact that all the materials exist in my design, always a plus. After some testing in my basement, I figured out what works. If you can find a tee that has a 3/4 ...

Re: Douchenator Project
@DX: I'll double check when home, but I believe I bought a brass female 1/4" NPT fitting and found that it didn't fit. It's possible there are different types of schrader fittings. @Andrew: That buy.com link you posted makes me think that schrader valves are similar, but not identical to, 1/8" NPT s...

Re: Douchenator Project
Saw discussion of Schrader valves here and figured I would ask - does anyone know what the official "thread spec" is for those valves? In other words, if I wanted to buy an off-the-shelf "female" piece to fit a male schrader valve stem from (eg) a tire, what would I be looking for? I could be stupid...

Re: drink maker brainstorming
@Andrew: You're talking about just connection to a two-liter bottle, right? The biggest challenge I have is of how to get liquid out and gas in through the same fitting. Conceptually, it's no problem (and one could CAD up a part that would very obviously do the job) but it's tough putting something ...

Re: drink maker brainstorming
It also raises an interesting question: given the low-cost and widespread availability of 2 liter bottles (and hence their use by pressure hobbyists) why hasn't someone produced a screw-on pressure fitting for those bottles? Seems like there's a market.

Re: drink maker brainstorming
That's the current setup, actually - rubber boot hose clamped (as they're known this side of the pond) over the neck of a tequila bottle. No pressure in that setup, though, just gravity feeding.

@Andrew:
Thanks for all of the helpful hints, and good to know that 22mm fits perfectly. I'll try boring out the cap and see how far that takes me.

Re: drink maker brainstorming
General Update: I tried the "two tubes one cork" solution that Andrew was kind enough to post an image for above (04 May 2012). It works ok, but you've gotta be really light with the pressure or the cork blows out and scares the crap out of everyone. Capping seems out of the question, since with two...

Re: drink maker brainstorming
Schedule 80 PVC. PVC solvent welding is safe for potable water, so I hardly see how it would be any worse in this application. Use 4" PVC and fittings for your reservoir (a bit pricey, especially with the SCH80 tubing, I'm afraid...) but the SCH80 is rated for far in excess of 150psi. Use a service...

Re: drink maker brainstorming
When I first saw this, I thought it said "drink make brainstorming better!" lol! I have slight dislescia so I mess up words some times :lol: (I also mess up spelling so bad even spell check can't help, hope you all can read that). Not really one for building guns yet, I'm trying to master taking th...

Re: drink maker brainstorming
So the initial pressure is coming from an electronically controlled tire inflator capable of (roughly) 150 PSI. In doing this, I'd be making the assumption that the controls could fail and the glass receives the maximum physically possible pressure. Downstream, we may use a tank+regulator setup. In ...

Re: drink maker brainstorming
Thanks for the brainstorming guys. I like the idea of a two-liter bottle with thin tubing providing pressure and fluid exit. Later, we may look for improved aesthetics (maybe glass, though that seems inherently risky in a pressure application) and higher flow with thicker lines that may not fit well...

drink maker brainstorming
Hi! I'm new to the forum here and (in full disclosure) not building a water blaster at all, but a drinkmaker the uses pressurized air to get liquids out of reservoirs. After a few frustrating trips to home depot wherein I failed to find the parts I needed, I began brainstorming communities of people...
