Not sure if this link will post, I am still just a junior member.

Atlanta,
Can you link to the barbed cap you are referring to?
I think that something like http://www.amazon.com/dp/B00V334SME/?tag=skimlinks_replacement-20 is what he meant. There are other sources as well.
I was also thinking of using this for dispensing, but my trials with a standard picnic party faucet resulted in too much pressure drop in the line with resultant foaming there. I plugged up the facuet outlet and drilled smaller holes, which worked somewhat but I'm not completely happy yet.
If anyone has got this to work well please let me know.
Ok, so I followed what Thekeggingpart did up above. I purchased the ISI Stainless Soda Siphon, and a gas side keg part that threaded right on to the cartridge holder thread on the siphon. I used a 5lb tank with regulator set to 50lbs, and the bottle did not take a lot of CO2, nor did the water get nearly as carbonated as when I use the carbonator cap on a 1L plastic soda bottle. I shook vigorously, and even held upside down and tried to suck out any air in headspace prior to carbonating. I read how the C02 cartridges are 850psi, and that there is some type of valve inside the siphon that will restrict gas in below 20psi. Anyone know what the issue might be?
Edit: I will attempt to remove the lock ring and restriction valve on the siphon as seen in photo 1 attached this weekend. Will report back!
Big coincidence. I'm trying to do the same thing as this thread and I bought a gas side keg adapter (for reference, it's a 5/8"-14 thread, took me ages to work that out before I was sure enough to buy the selzter and parts as I'm not a brewer).
I took my lock ring off when my ball arrived lock valve arrived this evening. After using a wide screwdriver anticlockwise with a spanner for torque, there is a plastic gasket underneath that slips off. To remove the pointy valve underneath I had to make a tool. Imagine the sort of tool you use to remove angle grinder discs but 2mm pins. I tried using a circlips tool but it started to bend.
I've put it back together now with the part still in situ and didn't take photos but to remove the valve you need to use two, 2mm circular bars at 10mm spacing and have a way to keep them aligned and apply torque to unscrew the valve anticlockwise. I had some 16mm aluminium rod which I cut, sanded the ends, marked a centre line, punched starting holes on the line to have the holes each 5mm from the centre of the rod, then drilled them using a drill press. I also drilled a central hole 4.5mm wide deep enough for the valve, but then realised 16mm is slightly too big to enter the valve but it worked anyway by inserting two 2mm drill bits in each hole blunt end first and then turned it using molegrips. I didn't really know the function of the valve at that point so I just put it back together.
I'm very keen to get this working but it's raining hard and my cylinder is in the shed do no more experiments for me tonight! Will be interested to know how you get on if you remove the valve, I haven't worked out how to bypass it yet, it may be a matter of just taking out the valve and then screwing down the lock ring but it might not reach deep enough, I'm not sure. There is a second plastic gasket with a hole in the middle, the sides of which cover the little metal hole visible on the outside of the outer 5/8" thread.
Good to hear you made progress. Do the valve / lockring have any function if a gas side keg part is screwed on and creating a permanent seal? I just assumed I'd gut any internal parts restricting C02 flow into the siphon. Thoughts?
I had planned to remove the valve but then I think the tiny hole on the side will potentially be open to the world except for the bottom gasket which does cover it. I don't know what the side hole is meant to do. The valve, as I put it isn't actually a valve at all, it's a hollow tube with a point in the end to pierce the chargers. I'm not sure if it has another function yet, it may just provide passage for gas to another valve below that I haven't seen yet. I think that it might just be a matter of working out the pressure needed to charge a siphon to and then keep pumping right until the end of the liquid, I need to do a bit of gas law calculation... I had intended to just use the ball lock valve with no internal valves. There is something below the bottom gasket that I am sure is an actual valve, but I didn't want to risk damage to the gasket and wanted to be sure if it really needed to come out at that point.
I took it all apart last night. The side hole appears to be a relief hole, likely since the cartridges run fairly high at 850psi. As mentioned, in order of disassembly there are the following 4 parts: lockring, gasket, brass nozzle, plastic 1 way valve.
The innermost part is a plastic valve that lets gas thru into siphon, and does not let gas out. It is actuated by an outer rubberized sleeve that expands under pressure, allowing gas thru the side ports of the valve just under the sleeve. The 50psi pressure I run out of my tank may or may not be enough pressure to expand that rubber sleeve. If it is insufficient pressure, then I plan to run the siphon sans plastic valve, and just JB weld the relief hole. 50psi is likely not enough pressure to do any damage to any internal parts on the dispensing side of the siphon. I am away from the tank til Monday, and will run the test then.
I have done nothing further with the siphon, but just turned my regulator up to around 70psi (my regulator scale runs out at 60psi) and instead of running out of pressure, it dispensed all but around 40ml of the contents this time. I'd probably like to have higher carbonation and I think the siphon can take higher pressure, likely far, far more. It was good enough for my purposes. If you can turn up the pressure on your tank, I wouldn't alter the siphon, I don't think there's a need.
I am likely to buy a different pressure gauge to put on my regulator so I can measure higher pressures and experiment further. Can someone tell me the type of thread specification that these pressure gauges typically use, and any useful advice on fitting or pitfalls I should be aware of?
Do you have a parts list?I changed the relief valve on my regulator to allow up to 145psi and charged the unmodified siphon to 100psi. It discharged all the contents and was well carbonated throughout. I may try higher pressures to compare, although there isn't any particular need. It's working well enough now.
