Well, I think people were pretty impressed with pneumatics at BrickFest! I've
been contacted already by people who want to use pneumatics in their non-technic
MOCs.
We are fortunate to have a pneumatics brain trust here on LUGNET. It is nice to
have peers like you and others.

Nor can I, but mine was blind luck: I won the raffle for the Technic Crane.

Yes, I've been trying to take more care in the hosing department, because they
can become a real rat's nest.

I am not sure what plastics LEGO uses for flexible parts (hoses, axles, etc.)

Aren't they all just concepts and prototypes? Sooner or later I think of ways
make each of my models better. It is just a matter of time.
Most of my MOCs are concept/prototypes. That is the

I can't wait until they are viewable to compare AND gates. SSC1 ended up using
my design of that. If mine differs, I'll post it too.

Would you like to work together on pneumatic documentation styles for Brick
Journal? I will be writing for Brick Journal both on CAD and MOCs.
