A while back I reverse engineered built the pneumatic module created by Akiyuky and could not get it to work reliably so I sought some help here. An LDD file is linked in the start topic a change made based on the comments of hknssn are posted in the 3rd post. Link to the post: http://www.eurobrick...howtopic=100705 Hope this helps.

I do not personally own the set, but the train motors should come with black plastic wheels with thin transparent rubber bands around them like so (white/transparent circle around the wheel): If the transparent rubber bands are missing I would suggest you contact LEGO customers services and ask for replacement wheels. My trains run with rechargeable batteries thus do not deliver a 9V total and I never had issues. I am always making sure the wheels are not pressed to hard against the "motor block" like snowvictim suggested.

Welcome TheLegoNewbie. The squell/squeal is mostly heard in my experience when the train PF motor is on a low setting. The motor has 7 speed settings in both directions when you use the included remote. You did try more than one click turn on the remote? Do the wheels turn very fast when lifted? If so I assume that you are on (almost) full speed and do not have a clue why the engine does not work when put on the rails. I have not had issues with the train motors.

Thanks a lot for the suggestion hknssn. I used it in my first version but could not get the gripper to work correctly then. I just tried it again on my current (third) version and everything seems to work fine. The only thing is that because of the larger turn it can make and therefore is stopped "early", the whole module (including base) is now turning on my glass table due to the impact on the L stopper. This is using the big hand pump, with the small motorized pump it works like a charm. Akiyuki and Michael Speelgoed use the 16 tooth which theoretically (and for them practically) can make an exact 180 degrees turn with a pneumatic piston. I am not sure how much additional stress is put on the turn stopper but time will tell. For anyone using my LDD with hknssns' solution, compensate the pneumatic piston position so the turntable turns 1 more teeth when the stopper L is removed in either direction. It works like a charm so thanks again.

Currently I am trying to build a pneumatic GBC module based on the videos of and .Somehow I keep having issues with a full 180 degrees turn. When not attached to the base, the turntable turns a full 180 degrees (like in the final part of Akiyuky his video). Once attached to the base my grabber does not turn fully, but only about 150-160 degrees. This way my version will not grab new balls but crash horribly due to not being aligned properly. Somehow the pneumatic piston does not push the turntable enough when fully extended. The only way it works ‘properly’ is when I operate the pneumatic pump as a madman so the swing speed turns the grabber fully but it should not have to operate on insane speed as shown in both linked videos. It might be that the module is not properly balanced but I copied most from Akiyuky and analyzed Michael Speelgoeds’ one too and they seem to work fine, although I must admit that the use of all the black pieces make it hard to see every detail so I might have missed something. Another reason might be the friction between the gear rack 1x13 and the outside of the module. As shown in the LDD file I made, there is a lot of free space between the gear rack and the outside of the module (all marked lime green) so I originally had a half bush on the lime green peg with cross axle closest to the grabbing arm so the gear rack would not ‘jump’ over the 16 tooth gear. LDD does not accept a half bush, due to not having enough free space which made me think maybe it gave too much friction. I removed it and pressed the lever 3M tight against the gear rack, but it does not stick so after a while the rack starts to slip on the 16 tooth gear. More importantly the grabber still will not turn a full 180 degrees. I am currently at a complete loss on what I can try next and was hoping someone had some pointers.

You mean ? It came with the mountain climber from CMF series 11.

Congratulations to the winners and thanks to everyone who entered the competition, you all were a great inspiration. Last but definitely not least, a huge thank you to the people who voted for my entry.

Thanks for your post Herky. Yes the backside is bland, I tried to add a fold able fire escape ladder below the first floor window but this made it look terrible and I did not have the bricks lying around to build an "American" fire escape like shown below. Feel free to copy/use ideas from the photos for your own build.

Great contest and thanks a lot for organizing it. Sadly, but understandably, there were only 5 points to give away so too many wonderful entries had to be axed from my not so short list of potential winners. People who I did not vote for, blame the lack of available points not your building skills.

Thanks for your kind feedback OrcKing, somehow I missed your reply.

Wow, that is a great looking modular building! I love the lettering, would you mind if I try and put them on my modular pub? I think it will look much better. The current version is the contest entry so I will not use your lettering to make it better looking for that. I love the washing machines, I build one with 2x arch 1x4 and an inverted dish which gives quite a big machine and it is rectangular. Your version is almost perfect (dial on top makes it impossible to stack a dryer on it but that is a nit pick detail). The apartment has great details too, I really like the kitchen and shower. The back entrance needs a green grocer, market street set or MOC with a pass through alley to be able to get to it? It is very clever because this makes the laundry work much better since it has the full width available.

Thanks cja. I agree that from the outside the attic/top part is one of the strongest parts.

Excellent looking "trapgevel". The coffee shop fits in great with the classic architecture of the building. The kitchen is a really nice build, it makes great use of the space. The apartment does feel a bit empty compared to the coffee shop, guess it is for rent/sale? I think, though might be wrong, it is either too wide (over 16 studs) or too narrow (under 32 studs) with its 22 studs width to fit in one of the building categories, otherwise yes it would be a great contender.

Great entry Chris. I love all the coffee details in the back of your house and the plate of cookies, just great. The picknick table is really awesome and all the mini figures give it a great feel. And I agree bow ties are cool. Good luck in the contest.
