So, i have finally understood. From the beginning, i had the right build, same before asking my question. Actually, this build allows the two cylinders from moving and so i thought my build was wrong. Apparantly, no.

If you’re interested, i have found a more performant build :

Thanks for your help and sorry for the disturbance…

@GuiliuG There is nothing illegal about it. If you take two old type cylinders and connect them with liftarms so the liftarms have 1 hole free between the cylinders, the space between cylinders is enough for just 1 plate. I have it in my hand right now and it fits perfectly. If you have space for 4 plates there, then you clearly connected the cylinders too far, probably 1 stud too far. It's really, really simple. Try with just one plate between them.

I have naturally looked at the pictures before asking my question but i can’t see correctly how the parts fit. For me, a plate is this part :

And the space between the two cylinders can’t be filled just by using one of this plate. I have same looked at the jennifer clarck excavator, where she seems to use a similar solution, using four round plates – or a round brick and a round plate which is the same solution ( 3 round plates = a brick plate). But this solution doesnt’t work properly… it’s for this reason i have asked you my question. But maybe your two builds are illegal and plays on the flexibility of the parts?

Sorry to be boring but i absolutly want to solve out this problem, without an illegal build because i’m a “hardcore” purist.

@GuiliuG Did you try looking at the photo? Because you obviously placed cylinders too far. Just 1 plate is enough.

Unless my cylinders have a defect, it’s an illegal build because the distance between the two cylinders, when they are hold by a thin liftarm 4L is a little less than the distance taken by the four 2*2 plates.

@GuiliuG
Look here: http://www.brickshelf.com/gallery/Sariel/VolvoEC290C/dsc03271.jpg
They are put back to back and held together by two thin 4L liftarms, and they have 2×2 plates attached to their bottoms to fill the space between them. Very simple.

Hi Sariel ! Can you explain me how did you connect your two old pneumatic cylinders together? I have already tried a lot of solutions and i haven’t sorted out the problem of connecting correctly this old cylinders… All my ideas were illegal builds, due to the strange dimension of this cylinders. You seem to use rond plates, and i have tried with these but my attempt has again reached in a failure…

Thank you in advance !

you should make an awesome working roller coaster that is based on a real life one.

@Jade2448 4 pumps, and you can see it on the video.

what kind of compresor did you use and how many pumps?
