Excellent work. Thanks for sharing the CAD files.

Logic suggests that 28-36 will have less backlash (however very very small difference). However using bevel gears would (arguably) lead to slightly higher friction, which would increase the issues developed from backlash. To tackle backlash I would recommend an approach similar to that which was used on The GBC Tower. The GBC tower used multiple motors to power at different positions on the gear chain. Alternatively, if you run power directly from the motor to stages (maybe every 3-4 sets) up the main chain, to provide more consistent power to the chain, I would expect similar reduction in backlash. This approach was used by Berthil on the Rainbow Wave to provide power at multiple points along the gear chain. Keen to see how you go.

I have repaired the BSX file which goes along with blakbirds file. It is here (https://bricksafe.com/pages/Jude_The_Lego_Dude/gbc/part-list-storage/bucket-wheel-tower-akiyuki). My build has the 4L bars and I recommend them. I have not tried 4L axles but given that it was Akiyuki's choice I think its probably the best. I can only assume the reason the animation has the 4L axle is because it was prior to completion of the file and since was rectified. Blakbrid did an excellent job at being 99.99% accurate to Akiyukis videos so I can only assume so much. Dunes' copy of the module has 4 sets of buckets and uses extra 3x5 thins in the output, hence the differing number (maybe). The rebrickable link is to a io file posted by 9vsystem, which has since been deactivated (for whatever reason), dunes has no control over this. I didnt see Dunes' mod to be a large enough change from the Blakbird instructions to warrant me doing another set of instructions for the same module. LEGO GBC NL's is probably build from Blakbird instructions (highly likely, with mods). The part list (above) and Blakbirds instructions are a matching pair and will allow you to build the module. Let me know if you have any trouble with the BSX file. Im happy to help with anything else if required.

Yep. https://rebrickable.com/mocs/MOC-165822/Jude The Lego Dude/type-2-l-motor-train-cart/#details You can also revert this to the AA battery pack. Some older details are here https://bricksafe.com/pages/Jude_The_Lego_Dude/my-gbc-modules/misc-type-2-train @Berthil Looking forward to seeing this robot arm. EV3 or mechanical? This is a note for anyone who may be reading this thread in the future. You will find all the bricksafe links I have posed (to date) no longer work. This is due to me deleting my entire bricksafe due to a security risk. Pls contact me if you are searching for instructions or CAD or part lists or whatever, I will find it in my archive and re upload it for you.

For this module, how it is in the instructions is mostly fine. 2 pumps are enough. However I did 2 other changes. msg me for details (I dont want to put it in this thread as its not meant for here). Great work @Seo-onDaddy.

Regarding Pneumatic module. (this question may be suited for the Akiyuki project) I have built it and run it for over 10 show days before replacing any of the moving parts. These parts where initially lubricated with some silicone oil, and I didnt have any issues at all. I think the parts could have gone for longer, but I didnt want it to be a hassle at my latest show so I changed out the parts. It is a bit of a its definitely a public favorite. The trick is low speed operation, run more pumps in parallel at less speed.

Having a single train would significantly simplify the process, I will consider it if I struggle with this too much or if I give up with the duel trains. Also I dont think I explained this well, but I do not desire to have the passing unit station be inside the Falkirk wheel, rather have it on the not rotating platforms outside. This simplifies things and means that I can probably develop a liftarm based linkage to connect the 8 tooth gear and gear rack trigger assembly. Also regarding throughput (or train sitting idile), im not too concerned as of yet, im really just trying to develop another unit for the system, and if that means I have to have another train and passing unit, thats fine for me. In the future the raised section may be elongated to increase time use, unsure as of yet. Thanks for your thoughts, I will ponder.

I have been playing with the possibility of making a Falkirk Wheel for the type 2 trains. At first this seemed difficult, after some further thought it seemed very difficult. Anyway I made some progress. I have not built it physically yet, only digitally. I hope to do so soon. I still need to figure out the entry and exit ramps (done) as well as a timing system which releases the trains into the stations simultaneously (a linear version of the passing unit but with a linkage between the stations). I had desired to have a mechanical link between the trains so they could detect each others presence, but this proved impossible, so I settled for timing there entry so they were the same and hoping that would work. The gearing proved elegant using a z56 turntable. The station is a modified elevator platform with 4 wheel drive which powers the rotation. A second ring of banana gears rotates with the platform to deliver power to the rotation assembly. I expect I will have issues with, 1. timing gates and there mechanical link 2. inconsistent entry and exit times and positions causing trains to be stuck entering stations 3. inability to construct a reliable entry and exit ramp 4. developing a mechanism which releases the trains from there stations at the right moment Hopefully the test build yields good results. Bellow is a link to some pictures of my progress. Link to pics Thoughts? Thanks Jude

I'm not too sure what you mean but, over the last few years the links in these threads have broken. Over time I have fixed them and re located files to my bricksafe. If I interpret you correctly your saying that you can not download the program file for the Fast Ball Sorter. I have re located that to this link. If that is not what your after, let me know and I will see if I can help. I hope that helps.

I made a PDF for my modification of the unloader. It uses the @doug72 idea of counter weight tires. Also @HRU_Bricks additional tire counter weights. I also changed the 'arms' that hold the ball container, so that they are liftarms, gives the entry and exist a little more wriggle room. Also the technic bionicle eyes are secured a lot better then the original 2x3 plate and slopes, in my experience these things fell off why too often. Here; https://bricksafe.com/pages/Jude_The_Lego_Dude/my-gbc-modules/type-2-unloader-mods Also I am working on a future train layout, I finished moding my type 1 crane to type 2, and it is now dismantled to document the parts to order more to build it properly according to my io file. Here is the planned layout. Also I long term tested the V4 turntable at a 2 day show. It had problems, as expected, the worst of which was the worm gearbox disconnecting, I have since made changes and updated the io file for anyone interested. Mostly though it was ok, It stayed in the whole time and really didnt give me too many headaches. you can see it in action here;

I use my one for a 180 degree reverser, even the PDF has one of the on ramps set up so that it can work in 180 degree set up, just by taking off the other train track side. Thats how I am going to personally use it in my train layout. the turning passing unit would be very funny to watch. I might actually see if I can figure that out. Thanks for the idea

@doug72 I finished the PDF for the new turntable. I think @Berthil is thinking of doing his own version using a Z60 turntable, instead of Z56, like in mine. I used a Z56 in mine because all my Z60 turntables have lots of friction and my Z56s are smooth. Shouldn't be too challenging to make a Z60 version. Anyway PDF here; https://bricksafe.com/pages/Jude_The_Lego_Dude/my-gbc-modules/turn-table Also how is the sliding passing unit going? Thanks

If this link takes you to page 1 of the thread then scroll down to module number 16, that will provide you with a link to the 'presentation topic' where you will find info and instructions and part lists for all the components. If it goes to page 22 then you are already at the presentation topic. If you are considering building the type 1 system I recommend the L motor train, if you are considering building the crane loader (unreliable ish...). For the compact layout the M motor train should suffice. (L motor train has no PDF so I can make one for you if you end up down this path) Please note that the type 1 train is not compatible to any type 2 components.

Ok, so I have built both type 1 and 2. For me type 1 was very reliable, but it has one critical issue, and that is traction. It can sometimes struggle when driving around. I found this to be applicable once you run the train for a day and a half at events. My solution was to replace the lego bands that are on the train wheels with the small white rubber belt that lego makes. This was able to provide more traction until the outsides burnt off a bit (which mine has). You can see in akiyukis videos that he only ever ran it short distances, due to this traction problem. As well as this traction problem the gear selector can occasionally drive into neutral when driving long distances, which leads to further issues. Where as the type 2 is much more capable of long distances, due to the 4 wheel drive and electrical switch. I have personally had many problems with the type 2 train, many more then the type 1, and I believe that akiyukis train has problems too, from someones comments I overheard in a video. Type 1 is simper, but can only go short distances. Type 2 is more complex but can go long distances. I think that due to the existence of type 2 everyone instantly decided that the type 1 train was bad, which I would argue not, It has been very reliable for me in the past, then again it has been very unreliable, but that just because it is a train, irrespective of its type.

So I know that HRU bricks designed a reverser that has the 24 tooth driver gear on both sides of the reverser: https://rebrickable.com/mocs/MOC-72808/HRU Bricks/modified-akiyuki-train-unloader/#details However that requires a complete rebuild of the akiyuki style reverser. So when I did mine I just free built it. The 10L axle that goes through the LHS 24 tooth gear, I changed to 12L, then under the station I made this assembly; that is the 12l axle now goes through a bush then an axle connector then a 4L with stop goes through the other side. But now you have to re position the gear racks. Sorry for the small images but eurobricks limits image size. I hope to do instructions for my final updated/modded reverser, but that is not in the near future, unless....
