Lego pneumatic engine (one cylinder)

[fox123456789ish]

how?



[inniable]

jeg har laget en lignene motor men for ikke start på den, har gjort alt som deg untat at jeg har et 24 tannhjul istede for 50 tannhjul som du bruker

Håper du skjønner norsk.

Inniable

[jardok01]

chu chu!!!!! XD (train)

[DuckHunt20]

put a fan on it lol

[gcndavidmn]

That's brilliant! Great illustration of how an engine works.

[keyboardjeff]

Where can you get those flywheels? It seems I am the only one who isn't using those wheels.

[2013dak]

were can i go to get the parts to build this motor ?

[2013dak]

Were can i buy this? how much?

[Kpilot786457]

wow the cylinder is slow but the wheel is fast.. cool!

[williboooooy]

That is one quick LPE!!

Really nice job man 5/5

[SuperGoodEats]

how much psi?

[MrKILLER0713]

Awesome...

[abbe5225]

tja var kan jag få tag i såna här saker? some luft sakerna ?

[blewie14]

Awwww cute =D

[fixitdude74]

similar principal to a steam engine, walschaert steam valve, without the reverser.

[myburntfoot]

smart! :D

[ctgormans]

How do you build this ???????

[jammy453]

are your pump the air by hand or by compresor?

[10paperplane]

hej

jag har byggt en sån där motor men den går inte....vet du vad som e fel?

[rocketman468]

@10paperplane säkert fel taimat på ventilen eller liknande. langa bilder. jag PMar min email ;)

[MrRazmushenriksson]

@rocketman468 Tjena igen!

Jag har bytt konto så jag heter mrrazmushenriksson nu, jag hette 10paperplane förut...... skulle jag skicka bilder? håller fortfarande på att få den att funka XD. jag följde en instruktion här på youtube, men den funkar inte :O jag kör med vanlig handpump och inte några uppgraderingar (större hål i cylindern) utan allt är original. men det ska väl funka ändå?

[sjogge123]

@10paperplane som föregående skrivare säger.

Allting handlar om timing, jag håller på att bygga en ångmotor i metall och där handlar allting om att få de att öppna och stänga vid rätt tillfället

[secreamia]

make a tutorial please

[cascio100]

is gears red 42 tooth???

[SM96UK]

smply amazing coordination

[fagogarbejde]

how do you get the contact to switch that fast

[ponygtx]

Silicone spray, cylinder on 2mm drill out and heavier flywheel

sorry I about my bad english.

[rocketman468]

checka my other video. 2mm drill and much silicone spray and drilled switch

[punkgopher22]

buddy you just got your ass 1 more subscriber

[ThePajamaPlayer]

make it 2

[hondayamahafan]

is there any way to make this non ascillating

icantspell

[rocketman468]

what do you mean ?

[hondayamahafan]

make the whole cylinder/piston assembly not move

[TheShadowOfX01]

@hondayamahafan translation: is there a way to make a non-oscilating version of this

[muddupudda1]

i would blow it up with soo much psi

[rubenve1994]

oké thanks

[rubenve1994]

did you need a flywheel?

mine engine don't move, and i dont now why?

[rocketman468]

yes it have to have a flywheel to get over that "dead spot" and try adding a flyweel that is geared so it spins faster than the crank, then its just fine tuning the switch timing that matters.

[erahaar]

is it enough power to build a lego car that can drive with that engine?

[rocketman468]

more than enough ;)

[punkgopher22]

@rocketman468 where do you get the cilinder piece and what air compressor do you use

[katowsky]

Would you plz tell me where the air comes from , the amount of press... Thx !!

[rocketman468]

from an air compressor at 6 BAR i dont know how much that is in PSI sorry

[katowsky]

thanks for answering

[newforestroadwarrior]

87 PSI.

[helpas345]

chuga chuga choo choooo!!!!

[rocketman468]

hehe :P

[jakemears97]

reminds me of a steam train......

[triggerdance]

tutorial needed

[technicdesigner]

@triggerdance u dont need a tutorial just look at it and copy the setup

[triggerdance]

@technicdesigner ok

[koen1koen]

make instructions plzzzzzzzz

[RjbsNXT]

wow

[wowXmaster]

can you make a bilding hoe to for it?

[topitapi]

Whats bilding hoe?

[chrismofer]

NICE!!!!!!!

thats genius!!!!

it switches perfect!!

[L3G0nerd]

impressive

[blubbersmith]

cool

[28kingIV]

where do you buy them in Canada ?

[davidl343]

what kind of gear was the big one

[rocketman468]

40 tooth

[evinsteven13]

does lego make parts specifically for stuff like this?

[rocketman468]

no they dont :D

[rcfreak2424]

make instructions

[Minifig666]

Have some manners at least say please.

Also very nice engine I made my own and then found my eBay ordered pneumatic cylinder was broken. (It only expands but when I go to contract it leaks from the top can anyone help me?(I think the seal is broken.))

[rocketman468]

yea got same problem with some of my engines. the lego isnt built for stuff like this so it breaks. if you try to build a inline 4 with an engine rock solid engine block it may not leak. but cuz this engine dont have an engine block the cylinder wobbles and creates leaks

[Minifig666]

Thnx for the help, but my one doesn't work even whilst mounted in the engine and it has gotten worse and worse. Also I only have one cylinder and I cannot find repairs on the net anywhere. (I think putting it in the engine made it break)

[Thunderdome123]

I think i read it on a site or somthing like it: that if you send in a broken piece of your lego set to your nearest lego company, then you'll get it fixed back for free. that's what i thought...

[vVeazel]

Keep the cylinders and switches lubricated with a silicone based lubricant, and they shall last longer.

[WillyWonkaChocalate]

But DON'T USE WD40 the oil base in lubricants like these will corode the plastic.

[maschine133]

hello that is a good engine can you me a building guidance gives?

[rocketman468]

i dont think you need any instructions just take a look at the video. i uses a 40 tooth gear and 2x 1x1 liftarms as a crank and then you can figure the rest out youself i hope.

[lukebob1]

can you put a picture of the inside, when it is moving it is blurry, and you don't show the inside when it is stopped

[suNproduction1]

made one like that ^^ thanks for posting : D took a time before i understood the timing, but it works now just need an air compressor : D

[mac550]

that's quite cool, nice one

[pagani8]

Not very fast for already drilled inlet...

I've aslo seen the other one, faster but i've gotten my one cylinder (big cylinder) to run faster without boring the cylinder :P

[legostuffguy]

did u drill out the cylinder? how did u get it to go so fast

[rocketman468]

yes the cylinder is drilled out and im using an air compressor

but i will soon upload my improved engine that is much faster. that cylinder there is leaking so i changed it with a new one

[ericstranne]

i have... search for "home made lego cars" and you'll find 'em

[rocketman468]
