Hello and welcome to the forum ebay is also good for joblots.

Burf You can buy hose, Here at Blokbricks.

What a big brwt of a thing,this is definitely a must for the crane fans.

Mmmm.... I wounder why Grohl is asking for the part quantity for? I think a T style truck would be good Grohl if your looking for inspiration.

Nice looking tractor.

I was not going to add it to a moc,it was just for an idea of mine,many people hate Pneumatics as they are hard to control so i thought i would try to come up with a easy way to control them.

It looks great what are the problems you are facing? Driving like a wet cake on skates sounds like it is the lack of control that is the problem but if you geared it down enough then this should not be the cause.

Here is a pic of the device,if i can get it to work you might get the following advantages, Gearing can be made faster or slower to control the flow of air to the ram. ..............................Thats it. More pumps can be places beside each other for more air.

I am lucky in that i can use all the lego cad programs to degrees but i dont boast about it or do i ? ,but i would not say it is best to build in cad first rather than in the real,i am also 21 with no degree but i don't think that matters to much. Oh i thought you were a 20 something.

I have made a gearbox that selects which pump to power each pump is connected to a switch which then goes to a port in the ram,i can remove the switch as this does not do any thing. All this should be run by power functions.

I am working on a servo switch device but i need to figure out a way to release the air from the pneumatic circuit,i tryed a valve block but that did not work.

Don't you think that the tower might be a bit small in terms of height by the time that you build the fort walls up?

Ah yes, build one of them that would be thinking out the clock a bit.

You could buy metal axles for making your car rc from Brick Machine Shop ,Enzo the owner also does custom orders.

Operating excavators is good fun from time to time but that is not really a hobby,I cant think of any thing which is better than lego (technic).

No i don't think so Why don't you use a technic turntable with some small 'city wheels' in it?

Sorry Tim misunderstood.

Edited

Pf attach /disattach? So what other great technic power functions stuff should we get?................................................................ah yes,

Too much resistance with two bands compared to one,mayby they found this out after the cad or paper work art work was done.

I got the loader and i did motorize it,you could fit a ram to the steering to add more pneumaticability, (new word i made up?....... ) or you could just fit a motor.

Well it's cheaper than this one. Oh Man

Enzo if you sign up to photobucket.com you can upload your picture an then post it into you post.

Ah thinks Burf for your answer.

I wondered that to,it might be down to the power function signal breaking up. (not so good in a race if this happens )
