- Ghetto tubeless inflator – total cost 9p!
Another satisfied customer of this thread here. Followed the OP’s instructions more or less exactly, used 4.7mm ID windscreen washer tubing (which I already had for bleeding brakes) which was a very tight fit but just about ok. Mole grips to hold the tube worked well. Needed 60psi in the bottle to get a slack old High Roller to inflate on a Flow, with rimstrip. Didn’t blow my face off or destroy the house, which was a bonus. Cheers!Posted 6 years agospooky_b329Member
I once saw Panda Pop bottles (the little ones) being tested at the Badger Brewery. Can’t remember the pressure, but once they get to the critical point, the side suddenly gives way and bulges out like a party balloon, before it explodes. So if you see a bulge, you have about half a second to cover your ears. If you’ve gaffer taped it, who knows 🙂Posted 6 years agoproutsterSubscriber
Thanks to all who posted on this thread – managed to inflate an extremely stubborn Swampthing tonight using a 2 litre lemonade bottle! It had resisted all other efforts, almost used up a whole bottle of washing-up liquid the other night with no success.
Bit of a let-down though, the tubing cost me £2.49 from Halfords!Posted 5 years agochiefgrooveguruMember
How many psi in the bottle did it take? Almost 80psi to get my Swampthings to seat. Ace now I know how to do it though, with the syringe to transfer sealant I can do a tubeless tyre swap in a leisurely 15 minutes (aka 5 minutes in ‘forum bike maintenance time minutes’…)Posted 5 years agodangriffMember
Diving bottle works well. I’ve got a 209 bar 3ltr bottle off a mate who bought about 4000 at auction (ex-Falklands escape breathing apparatus for the troops who were transported by ship).
209 bar is about 3030 psi, so it will inflate anything from bike tyres to a paddling pool in about 3 seconds.Posted 5 years agoproutsterSubscriber
How many psi in the bottle did it take?
Same as you – 80ish psi. Also only worked when I took the valve core out – but then it popped straight up.
How comes I never get anything useful from Halfrauds?
I’ve found that it is far better to be lucky than good looking 😀Posted 5 years agowenanwhereMember
These diy jobs look mint but for anyone wanting something a bit more luxury I recently splashed out (well not that much, about £70 in total ) on a second hand compressor on ebay and one of these http://www.prestaflator.com/ got to say although a complete extravagance its bloody brilliant 🙂Posted 5 years agosbd16vMember
thought i would bump this with my effort,
1 x barb vacum fittings
1 x foot pump
1 x used helium bottle
and some silicon pipe
cost £0 as had everything in the garage
due to the high volume of the canister it takes a good few mins of pumping to get it up to 3 bar but once there its pumps the tyre with ease and i done 3 tyres (put one on the wrong way around doh lol)without anymore pumping :D:D

Someone on another forum told me of this method and I put a thread on here about it ….
For tubing, I used the tube form the Stans sealant packPosted 5 years ago
Going to have a bash at this as I’ve got two dud inner tubes and a pop bottle to hand.
Is it easier to drill one hole in the cap and one in the base (in which case are there any tricks for getting the valve through the bottom hole) or two holes in the cap?
AndyPosted 4 years agoahwilesSubscriber
for pumping: one valve in the cap (presta)
connected to the tyre: a core-less schraeder valve in the shoulder of the bottle – it’s one of those schraeder’s that has an external thread+locknut – so i can use the locknut to secure/seal the valve.
but i honestly can’t remember how i made the hole in the shoulder of the bottle…

I wouldn’t drill a hole in the base as I reckon it would compromise the bottle.
i only need to pump mine to 40psi, experiments with pop-bottles in my youth revealed that they can handle at least 150psi..Posted 4 years agomrblobbyMember

I don’t doubt this. Though if the bottle was compromised with a hole I reckon it’d split well before 150psi. Why not give it a go and post a video on here 🙂
Maybe; the jeans leg (and eye protection) seem sensible precautions however it’s done…

I posted mine up on the first page http://singletrackworld.com/forum/topic/ghetto-tubeless-inflator-total-cost-9p#post-2616217 – that has a hole in the base, and I’ve pumped it up to ~120psi. I honestly can’t remember how I got the valve in the base, though the two obvious ways I can think of are either using a bit of thread tied around the stem to pull it through or put it on a stick and put the bottle on top. I suspect I did it with thread…Posted 4 years ago
