[BALLERDD7]

Do I have to have a special computer piece to use them?

[foxbox61]

For pneumatics? no.

[BALLERDD7]

where u get the air tank at.

[foxbox61]

I bought 2 LEGO Technic 8299/ 8250 sets on eBay: it has a tank + pneumatic parts + many yellow technic bricks.

[BALLERDD7]

Can u get them at a store or only on ebay.

[foxbox61]

i presume you are referring to the tanks? Do this go to peeron dot com and search for set 8250. Look in the list for the airtank, and click the link before it. Peeron will then show all sets that contain a tank.

Of course this works for any part....

[BALLERDD7]

Im wanting 4 pneumatic cylinders, an air tank, and a switch becuse im wantin to put them on a rc car as hydraulics.How do I buy them also?

[foxbox61]

Sear eBay for "lego pneumatics"; there are a lot of people who sell seperate pneumatic parts. Use Peeron dot com to search for sets (like my favourite the sub marine)

[BALLERDD7]

One more question, r these pneumatics expensive? Thank 4 ur help.

[IllegalMavamaarten]

I don't know.

I have a large truck with 3 pneumatics in it, to make a 'grabber', and also for opening the motor.

It's really cool, but I still want those blue pumps, and an air tank.

...wow

[ghostviper]

Very nice. Your good :P

[ruuman]

You could try filling the air system with water, this will give you a far more even pressure so less lurching. Very nice though

[Sparrow338]

Problem with filling them with water is that the system isn't closed, the pneumatic swtichs leak all over the place when you switch them. Other than that I have found that doing that works great.

[ruuman]

ah right, I broke my switch valve the first day I got it and only had the crappy red cylinders which bent under the torque. so was only doing direct actuations and found that water gave better performace. I've just got some yellow cylinders so will have to play a bit. I wonder if a thick fluid may help like cooking oil?

[hypergoth]

one day i too will know what the hell you people are talking about... =]

noice btw, 5 *

[iamloudmusic]

nice use of mixing chain and vehicle track, though I would have used gears on the scissor lift instead of pneumatics.

[foxbox61]

Yes, you are right. Pneumatics tend to have 2 states: on/off, up/down, etc and nothing in between. And controlling them is consuming motors to (pump + switch)
