Yes , I was wondering about how long the model can be but it should end up coming out at about 9900 studs³. I used a 15 l liftarm as the steering linkage:

That looks great so far. I will be interested to see what it looks like when it is finished.

I decided to build a concrete pump for the first contest I enter. I see such vehicles regularly on construction sites, so I think this vehicle should be ok for the contest. It will be inspired by the model of the Liebherr 42 XXT: This is my progress so far: Thanks for reading and any comment is much appreciated!

Good idea! Have you videos for your modules? I would like to see them.

GBC Module - Lifting Rim This GBC Module lifts the balls in a rim. Here is a render of the mechanism: And here are other photos: Here you can find the io.-file and all renders in higher resolutios. Thanks for reading, I hope you enjoyed it.

I built it studles for challenging myself, I think it would be much easier to build it with studs. Also I have not much parts with studs, so I normally prefer to build without studs.

Mini GBC Loop This is a loop with one lever as lifting mechanism. I hope you like it!

I've built a few little GBC Loops: Here to the topic. Not all of this loops are in this topic. They will come soon.

Firstly, thanks for taking the time to write this feedback! It's very helpful for me. I will try to respond to each of your points. In general: You are right this is a bit difficult but once it's in the right position, it should actually hold. Yes, these connections are a bit flimsy, but if they were made stronger, for example with Technic Pin Connector Round 1L [Beam], the marbles would no longer roll in the middle, which would be a problem especially with the "axle lift" as the marbles would then roll to the side and onto the floor. I think you mainly meant the other alignment, which is explained below. You can remove the motor by pulling out the two tubes and pulling out the two marked submodels upwards. Then you can connect a hand crank on the other side with the help of a longer axle. You are right, this one needs some speed, but that should not be a problem if you have full batteries. Instructions: Step 1: Fixed Step 28: The alignment was hard, you are right. But because the arm for the marbles is directly connected to the feeding mechanism via an axle and the Technic Pin Connector Toggle Joint Smooth Double with Axle and Pin Holes, I didn't find any other easy way to make the alignment better. Step 36: See above. Step 45: Fxed with another order of parts and a submodel Step 53: Fixed. Step 113: Problem solved by leaving out a half bush The inventory on Rebrickable is also fixed. I hope this was helpful.

Small Technic GBC This is another GBC Loop. This time it's a very small one. The io-file can be found here together with the part list and the instructions. This MOC on Rebrickable.

This looks great and like it could work well! I would love to see a video how it works.

Thanks for your comment! I have seen this sweeper and thought about how to rebuild it with a different mechanism and only from Technic parts. This is the result!

After reading this topic my interest in these things has been rekindled. I don't know if this has been written here before, but I thought of this one:

Philtech's GBC Modules Here I would like to present you my GBC Modules. First of all I want to show you my GBC Module - Slider. GBC Module - Slider (see below) GBC Module - Lifting Rim GBC Module - Slider It has a slider that pushes the balls up an inclined plane. Here a few images: Here you can see the mechanism: The io-file can be found here: https://bricksafe.com/pages/Philtech/gbc-module-slider This MoC at Rebrickable: https://reb.li/m/112266 Thank you for reading and I hope you like it!

A while ago I built these things, luckily only digital:

My GBC Loops Here I would like to present you my GBC Loops. Technic GBC Small Technic GBC Mini GBC Loop First of all I want to show you my Technic GBC Loop. Other loops will come later. Technic GBC Loop It has three different ways to transport the balls forward: an arm that lifts the balls, with a separator in front of it (like in my small GBC (I will present it here soon)): a conveyor belt: and three small rotating arms: This MOC is already for a while on Rebrickable. Here is a video: More photos, instructions, parts list, and some 3D files are available here. Thank you for reading! I hope you like it.
