[Closed] Ghetto tubeless inflator - total cost 9p!

Use said bottle as a dope rocket after, to celebrate....?

DrP

GEEEEnius 😀
Fortunately mine go up with a hand pump!!!

To be fair a 40psi bong would be er, interesting.

good that and, on account of the ghetto aspect there's an extra

yeah BWWOYYYYYYY !!

(I'm doing that clicky fingers thing here too)

<just copy/pasted and emailed to mbuk for my £100>

looks good bud...proper brainbox like

EDIT: 40psi bong...!!!!!!! would beat buckets anyday of the week!!!

Top bodging.

Good idea that, bit like a diy version of this

Thoght about something similar in the past for seating loose tyres on stans, put a wrap of tape round instead though

I thought about this a while ago when I converted mine, but they went up with a track pump.

Could use a 5l water bottle for more volume. Would probably need to tape that up as they're square edged.

Dunno if these would have gone up with a track pump - proabably with a bit of faff (stans rims after all). Decided i'd apply a bit of bodging rather than do the normal pump like a mental for 5 minutes whilst swearing.

I've never ever had to resort to compressor help ......up till i helped a mate out to do his as "they are a piece of pith" furiously trying to pump with my track pump whilst he looked at me like "you said it was easy you ****tard" I concede defeat and 2 secs hooked up to my old mans compressor and they're rock solid....
when i move back into my house its going to be the 1st thing that gets purchased for my workshop, actually probably 2nd after obligatory soft/hard porn calender...

Nice one!
Will the pressure open the schrader valve to inflate the tubeless setup?

Trackpump worked easily for me, but not on my mates. must be the rims - I'm dtswiss, he was mavic I think

Pressure should open the valve - if you've got 40psi in there. No idea whether it'd inflate quick enough - I only run tubless. You'd find it harder to bodge with schreder valves for the resivior.

Looks like a fancy shake n bake setup

I made one of these a while ago for a few pounds (only differences: ball valve, pump adaptor, 3l bottle). It works so well I can't believe no-one sells them (health and safety?).

A few key points:
1) make sure the bottle is for fizzy drinks (ie. designed to withstand pressure)
2) make sure the bottle has no damage (scratches etc)
3) fill the bottle with water first and pressure test well above what you plan to use it at (I pumped it up to 100psi but understand they normally fail above 150psi). Since water is incompressible it doesn't store energy and so a failure won't do any damage.
4) I've tied the valve assembly to the bottle in case the threads fail (to avoid high speed projectiles) and wrap it in a blanket in use.

Just seen this... Genius! Off to have a go at making one myself, have all the ready components already...

Only just spotted this thread - made mine almost 10 years ago, and have posted on here a few times, so hopefully I might have inspired some of the others on this thread. Though compared to the OP I inserted one valve in the bottom of the bottle - more hassle to get it in there, though maybe easier than two in the cap - and used a proper plumbing valve and pump adapter like totoro's version:

Works really really well.

Best bike thing I've bodged in years! And they call me the bike pikey

Spotted this thread last night after having trouble inflating my ghetto 29er wheels (for the first time ever, a track pump used to suffice, I guess the tyres have stretched?), I went for Ewan's method. Works an absolute treat, thanks.

Could you acheive the same thing from a spare car wheel/tyre inflated to 40psi at the garage/by footpump - that would be a huge reservoir?

Yup. All you'd need for that is a double-ended inflator hose.

For tricky rims/tyres, this sounds great. Will try it.

Looks cool, although I've always just used a track pump and had no problems.

However, how much air could you fit in a normal 750ml water bottle? Do they leak? I'm thinking of a cheap, reusable, co2 cannister, that fits in a bottle cage on a road bike, and doesn't look out of place.

Would be weird if someone tried to drink out of it though. What's the volume of a 700x23c tyre?

wouldn;t it be easier just to carry a pump - you can use all the uncompressed air that's freely available where you happen to have a puncture?

2.1m x (23mm^2)/4 ~ 1.1l (or a 2l pop bottle at about 150psi)

how much air could you fit in a normal 750ml water bottle?

^^
Fail!

DrP

This is absolute genius! I've faffed around with tubeless for a couple of years using a track pump, often giving up in frustration and sticking a tube back in. Knocked up one of these and have just converted two wheels in under half an hour (stan's flow and maxxis tyres.) Brilliant. Didn't even bother with the soapy stuff.

Big thanks to Ewan for posting this.

where are you lots getting this tubing from? I'm tempted to try this, never had a problem with Crests and just a track pump but just switched to Arches and can't get the same tyres to catch the air at all.

SORRY ABOUT THE CAPS-LOCK!

BUT THIS IS REALLY IMPORTANT!

DON'T PRESSURISE BOTTLES THAT AREN'T DESIGNED TO HOLD PRESSURE!

FROM PERSONAL EXPERIENCE*, A FIZZY DRINKS BOTTLE CAN HANDLE ABOUT 150PSI**, BUT A 'SQUASH' BOTTLE CAN'T HANDLE VERY MUCH AT ALL.

DON'T PRESSURISE 'SQUASH' BOTTLES, THEY CAN AND DO GO BANG.

IN A LOUD AND SCARY WAY.

careful now.

X

(you can get 3litre fizzy drinks bottles if you want/need more volume)

(*water rockets, with a little testing, and some stabilizing fins, and some maths, you can send them about 200m...)

(**please don't go this high, it's loads, it probably won't go bang, but it'll take your face clean off if it does)

Used an old coke bottle wrapped in gaffer tape, I may wrap it in a blanket next time just in case! Found that pumping to around 40psi was enough to do the job.

Bigjim, the tube I used to connect the valves was cut off the end of an injector thing that I had lying about that originally came with an expanding foam canisters from B&Q.

ARE YOU SHOUTING BECAUSE YOU HAVE FOUND THIS OUT THE HARD WAY, & ARE NOW A BIT DEAF ??????

He, he....

😉

Seriously, I may try this method as for me its usually use a track pump, strike lucky & the tyre seats & inflates immediately, or it doesn't & I end up going into work to use the compressor which is a no-no at the weekend & then i've to wait 'till Monday. So, yes, think i'll give it a go.

Where can I buy the tubing and a stop valve from?

Unless you want to build a deluxe model then any old bit of tubing will do as long as it fits on the valve and that you can bend it to pinch it off. If you want one like aracer or totoro I'd search down my local DIY store's plumbing aisle.

This was my effort...

yes.

🙂

(pardon? - speak up! - can anyone else hear a loud ringing noise? - etc.)

I finaly got mine inflated (alex rims, maxxis tyres) by wraping electrical tape round and round and round the rim untill the tyre bead was actualy tight.

Went up with a track pump (and not even a particularly big volume one) and added about 30g to the setup.

Haha, I had a road tyre explode in the kitchen the other day, took me 30 seconds to realise that the radio hadn't actualy turned off!

excellent little trick. its certainly made them inflate fast enough, but i think the bottle top leaks a little bit and the tyres going down slowly afterwards. i might need to wait for it to be fully down, then get some pliers on the locknut for a better seal.

didnt go up at all leaving the inner core in, so im a bit worried im never gonna get it blown up and stay up :-/

great fiddle tho for getting the tyres up quick. well done 🙂

I'd thought about doing this but this has solved a few issues I wasn't sure about....

I've found an even better way to get your tyres to stay inflated, and with far less faffage!

Et voila:

[img] [/img]

I know, I know. It'll be all the rage next year....

🙂 correct. less faffage in your garage, but more faffage whilst your riding and get a puncture 🙂

Not really. Bung new tube in, pump up and away. Not stopping every two minutes to pump it up again cos the hole's too big for the sealant to fill propply. 😛

not very likely tho. and in the very rare occasion that may happen, just 'bung new tube in, pump up and away' 😀
oh, and wait for your mate whose tube has just got another puncture 😉

just 'bung new tube in

Ah, right, ok....

😆

I is win so ner. 😛

Was contemplating one of these for when I go tubeless, then I remembered, I've got a compressor in the garage! 🙂

I just had an idea - anyone know where you can buy hoses that clip of screw onto scrader valves?

Car tyre + 1/4 turn valve + 2 female scraders (or 1 scrader plus one presta) and voila -instant 30-40psi reservoir and fast siphon.

Anyone killed themselves/blown their face off/destroyed part of their house using this thing yet?

Built one of these yesterday, great invention! Cost me about a fiver, aquarium tubing, plus bottle of Diet Coke. Awesome! Very nerve wracking pumping it up to 80psi, but all good so far.

I've made one a few weeks ago, its made things much easier

tick - bump

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!

I've used mine with great success... when the valve core is removed. With the core screwed in it won't depress to let air in and inflate the tube. This is pressures 40-80psi

Its amazing how quickly it'll blow up a tyre though!

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 🙂

great thread

Real men wouldnt worry about such things 😉

From soggy bottle rocket experience a 2 ltr Coke bottle goes at any where between 150 and 180 psi. That's when 30% full of water. Never had one fail at less than 140 psi.

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!

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'...)

prouster - how comes I never get anything useful from Halfrauds?

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.

How many psi in the bottle did it take?

How comes I never get anything useful from Halfrauds?

if anyone wants a cheap steel tank, try a commercial vehicle breakers. They have an endless supply of air brake tanks which can be had for a few quid.

Just inflated two 2.35 super tacky high rollers onto Mavic CrossRide wheels using a 3ltr cider bottle at 110PSI. Worked beautifully.

Bump bump

Note to self, don't use that 2l tesco plastic milk carton again. 40 psi and BANG!

Having built and successfully used one last night, am now going to enter Scrapheap Challenge!
Classic Bodge. Stan's should post a link to this thread on their website..
Well done whoever invented this contraption.

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 🙂

Another happy customer. After having a nightmare trying to seat a non-UST Baron on Mavic 819s thought I'd give it a go.

Cannot believe how well it works. Thank you thank you thank you thank you! 😀

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

works perfect

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

[IMG] [/IMG]

That looks ace but using an appropriately sturdy container takes the fun and danger out of it!

I'm surprised nobody has come up with a cheap product that does this...

thank you very much. i used to go through CO2 but this has bodge is the work of a genius. thank you 😀

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 pack

Final gave this a go. My first attempt at tubeless. Worked first time, I think it was beginners luck.

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?

Andy

I drilled two holes in the top cap. I wouldn't drill a hole in the base as I reckon it would compromise the bottle.

I botched a version with a 1L bottle last night, took a few goes, but worked, pretty sure a 2L bottle would work a treat...

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 only need to pump mine to 40psi, experiments with pop-bottles in my youth revealed that they can handle at least 150psi..

Maybe; the jeans leg (and eye protection) seem sensible precautions however it's done...

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 🙂
