another simple tubeless inflator

Did you ever dream of 50 gramm, ~10 euro device making possible to seat tubeless-ready tire with a hand pump in 5 minutes? It is almost here!
Basic idea is absurdly obvious:
All we need is just to attach a branch with tap to the pump hose.
First we inflate an intact tire with tap closed and then open tap and direct the air burst from this donor tire to the tubeless.
So far I've build demo model from plumbing parts - cost me the same ~10euro, little bit heavy at 350 gramm, yet it also looks beautiful.
my video is here https://www.youtube.com/watch?v=3_jkUMYHIC0
The test in youtube clip went abnormally smoothly, to be true these tire and rim are over two years together.
Physical effect of this device seems have to be approximately the same as with other similar inflators:
DIY "ghetto" plastic bottle inflator (I like it best)

I use the Coke bottle ghetto inflator, works every time, better to have removable core valves though for the burst of air exiting the bottle to come out as fast as possible, piece of 6mm automotive grade silicon hose, kink by hand and then release and keep pumping.....Currently riding a Whyte T130C, X0 drivetrain, Magura Trail brakes converted to mixed wheel size (homebuilt wheels) with 140mm Fox 34 Rhythm and RP23 suspension. 12.2Kg.0

Yes, I also admire plastic bottles, this seems to be the most charismatic solution. What I would like to see is a quality product - something like cap from Airshot inflator fitted to standard bottle and sold separately for 10 euros... I'm afraid it is not possible for safety reasonsI use the Coke bottle ghetto inflator
CO2 inflators and regular compressors are dull0 -
I love innovation. Good idea! I have been using 1m air hose with a schrader valve on one end and presta on another. Attach it to your car spare tire and away you go! Not my idea, origianally read about it as a quick way to inflate a 4x4 flat..Oh and if you have a really stubborn tubeless just pump up the spare to 50psi.Stay positive people

Thank you! Indeed, spare car wheel is a more obvious source of compressed air than bike one, I've seen a post with idea to pump bike tubeless tire with it here http://singletrackworld.com/forum/topic/ghetto-tubeless-inflator-total-cost-9p
I have too faint hope that there is any real innovation in some part of my setup. It is really too obvious.0 -
Yep I've found at last an exact copy of my device - dated by 2012!

Costs more than pumping up a coke bottle and more harmful to the environment!CO2 inflator has never failed for me.Currently riding a Whyte T130C, X0 drivetrain, Magura Trail brakes converted to mixed wheel size (homebuilt wheels) with 140mm Fox 34 Rhythm and RP23 suspension. 12.2Kg.0 -

It's cheap enough for once every few months and I drive a Jaguar so the environmental impact is insignificant compared to what I'm already doing.Transition Patrol - viewtopic.php?f=10017&t=130702350 -
No, the Co2 is created chemically, not extracted at all, extracting from air is bloomin expensive....

A more practical 91 gramm version of tire-to-tire inflator based on this valve from aliexpress
Mein was 8mm internal diameter, and it neatly fitted from inside to a 6/8mm silicone hose. Connections to prestas was made by first putting a short stretch of 4/6mm hose on presta and then putting main hose on it. System is perfectly airtight so there was no problem to pump donor tire with portable minipump within target 5 minutes.
