I was just thinking an axle or pin hole in the middle would make it easier and stronger to mount pneumatic cylinders when used for outriggers. Also, having a pin hole and axle hole at the bottom would make it easier to mount two cylinders together for an even longer stroke. I agree that the valves should be redesigned with the ports on the back. It would be so much better.

I like it! The transverse drive-train is really great.

I'd like to see a pneumatic cylinder with a 7-9L stroke. Also add an axle and pin hole at the bottom (like the LA's), and an axle or pin hole about mid way up the cylinder. And we need a servo motor.

Awesome! This has old-school written all over it.

Heck yeah! I'd be all over some XS motors. I think a motor with return to center and built in clutch would be even better.

Interesting idea. So, you are going to use 4 or those hockey puck springs? They aren't cheap, unless you have a secret stash somewhere. If you have a secret stash, I'd be interesting in some.

If you go to this link, and look at the pictures, it appears that the tank uses a "torsion" bar suspension made from axles. I've seen a few other people do it as well. One of the PF pneumatic valves I've seen uses axles as torsion bars to return the valve to center. And just an interesting (to me) side note that has nothing to do with LEGO: My '90 Toyota 4Runner uses torsion bars on the front suspension. No coil or leaf springs. The cool thing about my torsion bars is that I can give them a few cranks with a wrench and gain an inch or so of lift. I still like the coil sprung front suspension on my '00 4Runner better though.

That's an event I would love to go to. I really like the portal display. I agree with the Technic theme not being as popular, and I too noticed many people leave Technic stuff out of their photo galleries. I get the feeling that even EB overlooks us Technic folks. I've seen some amazing Technic creations posted here, but I have never seen any posted on the front page. Model team stuff yes, but not Technic. Part of the reason I enjoy going to the conventions is to try and get people interested in Technic. I have a blast answering questions about Technic. Last year at BrickMagic, a kid was walking towards my Technic tractor, and the mom pulled him away and said, "that's not LEGO, don't look at that". CRTLEGO, it would have great to have another Technic fan at BrickFair. We didn't have a big Technic turn out. Paul and I had some large mocs, one other guy had some moded sets, and there were a couple of kids with some smaller mocs. Not much else. Anyways, just my thoughts on that.

Sometimes I listen to music while I build, but when my brain gets fried, I watch a bit of TV before getting back into my project.

I used an articulating joint on the tractor I built. Sorry, I don't have very good pictures of the joint itself, but these pictures may give you some ideas: If you go to my youtube video , you can see the articulating joint at the 30 second mark.Hope that helps! Daniel

I like it! You've managed to fit a lot of features in a small space.

Fantastic! I've been waiting for LEGO to make the #5 and #6 panels in black. Hilarious.

There are pros and cons to both. I like the precision that LAs give, but pneumatics are easier to build with, unless your are building something that is remote controled. Downside to pneumatics is that it is more difficult to place them in remote control projects. My backhoe I built uses LAs, and it works fairly well, but had I known what a pain it would be to route all the driveshafts, I probably would have waited to accumulate more pneumatic parts to build a pneumatic backhoe. I'll build another backhoe with pneumatics someday, but I need to buy another 16 or so cylinders first. I did like the accuracy with the LAs though, and even though it was a bit of a pain to route the driveshafts, it was still a fun challenge. My next project is going to have pneumatics. Also, I find the longer stroke of the LA easier to build with than the shorter pneumatic cylinders. I'm with allanp on this, LEGO needs to make longer pneumatic cylinders. Just my thoughts on that.

I picked up this set a few months ago. Not bad at all! I was pleasantly surprised when I figured out that the rear "suspension" lowers when the bed slides back. Clever feature.

Looks great! I like the extending dipperstick.

Can anybody tell which panels are on the tow truck and log truck? The #3/4 panels are pretty obvious, but I can't tell if the hood panels are #17/18 or #5/6. It looks to me like the tow truck uses #17/18 and the log truck uses #17/18. What do you all think? I would really like to see the #5/6 panels in black.

Looks great! Interesting suspension design. It looks like it uses axles as torsion bars.

Well, the Unimog has some new pneumatic elements, so I think there is still hope for more pneumatic sets in the future. I don't know if we'll have a pneumatic set in 2012, but I'd be confident in saying we will have more in the future.

Oh wow! This part is awesome! The square hole in the middle is unexpected, but I like it. It gives room for a couple of pneumatic hoses. This part would be perfect on the two mocs I'm working on. Davidmull, this part could have a lot of uses. It could be used at the end of a boom for a rotating hook or claw, used as wheel hubs in large mocs, used as pivot points for pendular axles, etc. Very useful, imo.

I vote for a review.

I like it! Nice boom design. It looks like the boom uses pneumatics to rotate it.

I just finished up a simple video:

Thank you, Jurgen. I've re-uploaded the video with a different sound track. It should work worldwide now.

Welcome to the forum! I looks like you're off to a good start! It's always nice to see somebody else getting into Technic.

I had a chance to see this at BrickCon. Very, very cool moc. It caught my eye even before it was taken out of the container he used to carry it in. Really nicely done.
