I tried you approach but had some minor leaking, so I tuned it a bit: * drill the hole in the cap at 4mm so the tube fits through tightly * push a pneumatic tube through the hole * connect a T-piece to the tube's end that's on the inner side of the cap * then pull back the tube form the outer side and gently press the tube end with the t-piece in the hole Due to the tube being thicker with the T-piece inside and it's softer rubber material it will completely fill the hole without any micro-leaks. Still, as I liked this in your original idea, no glue needed! :)
Hi, I made one too, with a milk can or a bottle, but i drill 2 holes, one input 1 out put, but it doesn't work! the milkcan even exploded! can you please help?
You have to use a soda bottle, because it is pressure bottle and a milk can is not which is why it didn't work. Also the cap on the soda bottle is much thicker than the milk can cap which helps create a better seal. hope this helps
that looks great, I am just starting pneumatics and to be honest $50 aus for the storage bottle or a pressure gauge is just reticuloses. Do you have any suggestions for alternate gauges.
@@GreenGeckoLegoTechnicWorkshop in my video the lego air cylinder is not lifting one side off the chassis up but my other cylinder i have can lift it up with ease but its a 16mm in diameter bore air cylinder but its way to big for the chassis a 1/5scale or 1/8 scale will be the right size for my other air cylinders
Dude what tubes do you use, cause I don't know if the transparent tubes u use are different from the colored lego comes with. If so, then whats their size?
i have had no leaks with press fitting it without hot glue, i had 25psi in the tank for 2 months and it still had 20psi. 5psi lost in 2 months is not a big deal.

Great idea, i should of thought of that... Thanks for sharing : )
That is a great idea
Also what dose the pneumatic switch left and right for
Glad I read this comment before making it!
The designer, Green gecko, is a genius. 👌
that's some dank music there bud
thanks
Bro… tho was so long ago.. when we used dank
how much psi can it whistand before blowing up or leaking? iam asking both the tank and the lego hoses.
Well Lego pneumatics work up to 4.5 Bar, the bottles can take around 10 Bar.

sure. But also with the bottle i can't make pressure. Maybe because i have 2 holes i nstead of one?
Do you have a switch on the input? and what type of pump are you using?
I drilled 3 holes, 1 input 1 output and 1 for the manometer, I use an airbrush compressor to fill the bottle
Sounds great, the reason why i had only one output was because i like to combine about 6 together to make a massive air tank.
Green Gecko Lego Technic Creations I want to make a pneumatic engine that looks like a steam engine, could you create something?
i will have a look, ill let you know soon.
I made a engine that looks like some kind of steam engine, based on your fast 1 cilinder engine, but it doesn't run smooth, could u help?
make sure the timing is right and you have good air pressure and flow.
is it ok for solder?
Funny, had the same idea over 10 years ago.
How much pressure can the silicon tubes hold??
I tried them on 40 psi and the tubes started leaking air
If you push them on correctly. They can hold 100psi when the engine is running, 70-80psi for a Air tank setup like this one.
You can use a Zip Tie or Cable Tie to hold the tube on for higher pressure.
that looks great, I am just starting pneumatics and to be honest $50 aus for the storage bottle or a pressure gauge is just reticuloses. Do you have any suggestions for alternate gauges.
You don't really need a gauge
What if I don’t have the T piece?
you can use the Hose connector instead
@@GreenGeckoLegoTechnicWorkshop I found a T pièce not a Lego brand a random brand
Will it be able to lift over 1kg off weight
Yes with the right amount of pressure. If you use a 4 cylinders instead of 1, it will need less pressure to lift the same weight

Can u tell me where u buy from switches and small size cylinder, plz reply
Hi, i buy all of my parts from bricklink.com
Where have you got these hose?
ebay, search for 2x4mm food grade tubing
Thanks!
how many psi do you have
How can i get these air switches?
Hi, you can buy them on my store here. They are already modified for LPEs: greengeckoworkshop.com/products/modified-lego-pneumatic-switch-new-style
Dude what tubes do you use, cause I don't know if the transparent tubes u use are different from the colored lego comes with. If so, then whats their size?
same diameter, but they are a bit softer than the lego ones
How much PSI does it hold?
it holds 55 psi no problem, when you take it to 60 psi the hoses pop off.
Can you make that separator that puts the air to one cilinder then to the next cause i dont have that part
yes, just block the hose
Any idea how much PSI these switches are rated to?
They work around 100 psi no problems in My Engines, 55-65psi is the safe working zone for these switches.
Green Gecko Lego Technic Workshop thanks very much.
There is a mistacke at 1:52 ; )
how is it a mistake?
Green Gecko Lego Technic Creations I think it's Use one of these instead of Use a one of there
Green Gecko Lego Technic Creations There are two "and".
i see the mistake, i will fix it soon. thanks
Ok ; )
I made the air tank and it worked.
I detected a small leak around the T-piece. I might put some silicon on it.
hot glue works well too
Green Gecko Lego Technic Creations nope hot glue doesnt even seal with water, i would use silicon
this is a air tank not a water tank
***** but water has bigger molecules than oxygen or nitrogen so if it isnt watertight then air should rush right through aswell
i have had no leaks with press fitting it without hot glue, i had 25psi in the tank for 2 months and it still had 20psi. 5psi lost in 2 months is not a big deal.
Its very good, i built it but... Its not working😢 why?
Did you use the correct size drill bit?
The cylinder is working to slow and weak
Even i use hot glue for T piece
Can you please put the parts on mochub?
I will see what i can do, all you need is a switch, some T pieces and Pneumatic Tubing
I make one with glue and it works so good with 6 bar or more, so the engine works, and works, and works.. ;)
6 bar is quite a lot in a soda bottle from my experience
@@GreenGeckoLegoTechnicWorkshop it's a German soda bottle ;)
@@Xx_ToterTigerLP_Rockt_LoLxD_xX hahahahaha
Ryobi drills are awesome looking compared with b&d..
i use a DeWalt now
Hay lizard!
I love the music too
nice
thanks, you will need to make a few of these to power your engine for a while. 4 to 5 is a good amount
ممكن الطريقة تكون سهلة
