Tankman Posted January 4, 2015 Posted January 4, 2015 No Compressor - No problemNo electricity - No problemNo Co2 bombs - No Problem! I built this Air Chamber a while before Epic.Since I was servicing our own bikes, I did not want to go hunting for a compressor (or electricity) when checking Stans at least every second day.Been meaning to share for a while ... so here goes. You will need:Empty Coke bottleTubeless Valve with removable core.3x Hose clampsPump Hose and/or High Pressure hoseAir Compressor Handle (Midas for R60)Brass pipe connection to connect pipe and topcap Drill a hole in the bottom of the bottle, make sure the hole is smaller than the valve.You want a snug fit. Use wire or long spoke to feed the valve to the hole in the bottom.Heat the plastic around the hole up using a lighter, dont melt it! Pull the valve through using pliers.Secure the lockring around the valve using pliers. Make a hole in the topcap, again smaller than the connection you are using.Connect pipe to topcap and handle. Connect pump hose to other end of handle using hose clamp.(Pump head optional) and Voila! Inflate your air chamber and inflate your tyre! NB: I would recommend a couple of pressure test first!!You don't want your hand anywhere near this bomb, should it go off.Plastic exploding at that rate, will cut of anything in sight.Hide yourself behind a door, pump it up a couple of times, listen for leaks etc. As a rule of safety, I never pick the coke bottle itself up when it is inflated, use the handle or pipe to drag it where you want it. Inflating the air chamber to 7 or 8 bar is sufficient.9 bar you are moving into dangerous groundsanything over 10 bar ... you are on your own!In case you are wondering ... they WILL pop at 12bar, someone had to test it! A pump head can be attached if you so wish, I find it easier just to remove the valve core and stick the hose directly over the valve, especially when seating tubeless ready tires for the first time. Or if you have R1200 lying around you for a pump that does exactly the same thing, buy the Bontragrer TLR pump. Have fun!
BarHugger Posted January 4, 2015 Posted January 4, 2015 Just an idea regarding the safety.......maybe use an old tyre tube (the size for trailer wheels, 155/13inch) to pull over entire Coke bottle. If the tube fits snugly it might absorb some of the exploding force should the bottle decide to go BOOOOM. Another reservoir option to consider is a plastic radiator coolant reservoir found in vehicles today. They should be able to withstand the pressure......some already have a safety pressure release valve. Now just to figure out which vehicle make will work ideally......scrapyard visit.

Guest DieBees Posted January 4, 2015 Posted January 4, 2015 My flip! Awesome idea!! I like it. Thanks. I have always had to drive to the service station and work there. Im to selfish to buy a compressor.
beachless Posted January 4, 2015 Posted January 4, 2015 Is this really such a problem on 29"? I have always just done a couple of hard pumps on my 26" with my stand pump and then start to pump normally and never had a issue. I just ride with tubes on my new 29" at the moment because they are less hassle for me.

This is for seating Tubeless Tires or re-inflating after checking your stans ... on tubeless tires.

THERE IS A DAMN GOOD REASON WHY USING PLASTIC IN A COMPRESSED AIR SYSTEM IS AGAINST COMMON SENSE AND MOST HEALTH AND SAFETY CODES. (yes - i know coke bottles are capable of taking some pressure - but overcook it and all hell breaks loose.) Rather just modify your system to use a car tire as a pressure/air source - yes you can pump up a car tire with a handpump too....

I am busy constructing a cage to contain the blast, should that ever be needed. I am also aware that the bottle will have a limited lifespan with continuous use. Pressure test it, stick to below 8 bar (6bar is sufficient) and all should be good. You can fill it with water, put a normal cap back on and inflate to test. Just dont do it in your mom's plastic bath! *No guarantees offered.**Faulty bottles can be taken up with Coka-Cola.***Stupidity can be taken up with your parents.****Tankman takes no responsibility and can not be held liable ... for anything!

Alternately I have a small used CO2 welding cylinder you can modify as your air source - I will send it to you free of charge... it's a bit stronger.... I use a similar system for my racecar - using a paintball cannister - but it's CO2 - so probably not the best for sealant life.
Tankman Posted January 4, 2015 Author Posted January 4, 2015 Alternately I have a small used CO2 welding cylinder you can modify as your air source - I will send it to you free of charge... it's a bit stronger.... That would be cool.I gave much thought to getting a cylinder or compressor type cylinder but that bought me closer to just buying a new compressor. This was a DIY job with what I had lying around, plus it had to be portable. Obviously with certain risks but it did the job it was intended for that week.
Vetseun Posted January 4, 2015 Posted January 4, 2015 We used to make chlorine bombs with 2l Coke bottles as kids. Seeing the effect of that plastic bottle exploding was absolutely shocking. A really serious explosion. I specifically remember certain bottles being stronger than others. Like idiots, we would see who could hold the bottle the longest before chickening out. Listen to V12. I think he has seen the effect of something like this before.
beachless Posted January 4, 2015 Posted January 4, 2015 Try it without a compressor and revisit this thread.Ha ha I think I will stick with the tubes then for a while longer.
BarHugger Posted January 4, 2015 Posted January 4, 2015 VW Beetles used to have a simlar pressure system for the window washer fluid container ('69 model). The plastic container was located at the front onto the spare wheel. Had a hose that connected to the valve of the spare wheel. Used the pressurised air of the wheel to push the water from the container. Now here was the fun part.......direct the left window washer needle ball to the side of the vehicle.....push the pressure in the spare wheel to almost 4bar. People on the pavement always wondered where the sudden fluid stream came from......and almost always looked up! System was good for a 10m range. Later started to use the vertical window frame of the small triangle door window as aiming reference from the driver's seat. Sniper accuracy if I dare say....... Thinking of it......similar system filled with Stans and pressurised......will most probably sound like a wet fart.
Ampandy Posted January 4, 2015 Posted January 4, 2015 Eish. And did anyone realise that oil or any oil deposits in the bottle will add to a wonderful GUY FAWKES experience???
