Sorry for late reply, must have missed this post before. It was made by me awhile back, the white part is a 3D printed 3 x 3 x 3 worm gear box by Efferman. The lift was not reliable as hard to get the balls to load without jamming. I must have missed this post before, it worked OK without flinging balls, by using 12t double bevel gears it help get rid of gear backlash & kept the lift arms in step. Blue axle pins used instead of tow ball pins to stop balls sticking & Not moving onto next lift arm. Long arm used to get enough height so balls rolled back to the start again.It worked fine. -
Or run out of parts !

Thanks but credit should go to Jonas who developed it and made the instructions. I mearly adapted it to suit my proposed layout which have to fit on our dining table until proven before moving up into the loft to form part my Lego Train layout. The 180 deg t/t will replace the ballon reversing loop and the 90 deg will replace standard Lego 1/4 circle curved track. I hope to keep it fairly narrow. Doug

Now adapted the @Jonas turntable for the Akiyuki train system to give 90. deg. turn, very useful for a more compact layout. Train car reversed by hand for video demostration - hence the shaky camera !!

Nice MOC & presentation with a good balance of text & images - well done.

@Jonas Thanks for the turntable instructions. Downloaded the lxf file and followed the generated building guide. At times found difficult to follow as parts are shown put in place before other parts have to added below later in the build. Finally got it built and tested: Had a few teething problems with it working OK in one direction but not the other when the train car would derail as it left the turntable. It was also rougher turning in one direction than the other way. Finally found the problems:- An 8T gear meshing with the 24T gear was rough due to a slightly bent 8L axle - now changed. 8T gear was also rubbing on the last tooth of the gear rack as unit rotated. I was using the new 8T reinforced gear - now change to old style 8T gears and working OK in both directions smoothly without rubbing. Video: note unloader build not yet completed. The jolt as train enters turntable the 2nd time is due to track being 1 plate too low - now fixed.

Thanks for that answer. I sometimes find it quite hard to see where black parts are added to existing black parts unless zoom up instruction page. I have now used yellow 1 x 2 plates & tiles to fill the gap. I am now using where possible 1 x 2 bricks with 2 pins instead of 1 x 2 brick with 2 holes & 2 pins, they are very low cost and easy to get in the UK. Slowly getting to grips on how this train system is built and functions. Is there any information somewhere on how to syncronise the modules, ie. reverser / unloader - loader / reverser etc.other than trial & error. Hope I have enough space to build a layout & run it.
-
The problem:- After completing the build of unloader and reverser modules, testing revealed a problem with the wheels of the motor car often dropping into the gap & jamming at the end of the Lego track section before it runs along the red beams. I have ensured track horizontal at the entry point. When it sometimes worked the ball carrier lines up and unloading cycle is OK. The solution:- Last section of Lego track replaced by 16L rail track beams which eliminates the gap. Overhead view: Close up view: UPDATE:- Now found why wheels were jamming at end of Lego track. I had omitted to fill the gap in the track run with 1 x 2 brick with 2 holes / 1 x 2 plate / 1 x 2 tile stack !!!! However the modification I came up with does work.

Many thanks for the instructions - I will definitely build two for my proposed layout. One 180 deg turn as a reverser and the other 90 deg turn to save using standard lego track curves for a more compact set up. Have enough parts this time. Doug

I used the version which triggers every 180 degs. I will check again to make sure I have used correct modules. Now got it working & seems OK. I seperated the rreverser from unloader twiddled with the drive to unloader a bit and re-connected them and it works !!!!
-
Now built the reversing module using black shock absorber and the unloader module (without shocks) and coupled them together. Motor car runs in OK and the unloader lifts the ball carrier BUT motor car departs before empty ball carrier is placed back onto the motor car. Ball carrier stays in vertical postion on the unloader.the Any tips on how to syncronise this ?
-
Thanks , the ones I tried are from the Unimog and probably too strong. The ones on order are black with normal springs, I will try them first to see if they are OK., if not more ordering. Which shocks absorbers did you use ?
-
Now recieved more parts I needed to progress this build, 1x2 brick with 2 holes & 1x2 brick with axle hole plus correct 1 x4 x 3 panels. Just waiting on black shocks to arrive which seem scarce in UK / EU. As you say you have to pay close attention to following the instructions - hard to with the limited studded spare parts I have .It took quite awhile to build the curved unloader section strong enough. So far have built one motor car and the passing loop module. I can now finish the reverser / loader / unloader / through unit plus another motor car. re your turn table module, would it work OK if only rotates only 90 degs instead of 180 degs. want to use it as an alternative to standard lego track curves which take a lot of room. I will probably use two units, one to reverse direction after the through module and another for a right angle turn. What is the purpose of the two yellow shock absorbers in the unloader module ?
-
Thanks, I have found black with normal spring on Brickowl but none with soft spring which also are not available seperately anywhere. The yellow shocks with hard spring that I have are priced at £11.50 + each !!!! so might sell them.
-
Thanks for the info. I have built a motor car, and WIP on loader, reverser & unloader modules to start with to see how they perform before building a through module. I will add rest in stages with another motor unit and a siding module. I have ordered parts to build these but unsure which shock absorbers I need to order for the reverser and unloader moudules.
-
Thanks, for the explanation. So far unable to find the full inventory for Akiyuki,s latest version, can anyone post a link to it ? Sourcing parts plus black shocks as only have yellow shocks from unimog set.
-
I have checked all these parts I have, which ALL obtained via Lego Technic sets and cannot find any marks on them. Maybe. I need to go to SpecSavers ! !
-
Great, I have no idea how to make instructions. Now re-built motor module using correct instructions and sorting out parts for next module.
-
Yes I have been following the instructions as shown in the GBC index on page 1 of this thread. Item 17 Train Module Type 2 by Courbet. Seems the inventory index do not match the instructions !! I have now downloaded the link to the Akiyuki website which I will now use. PS - now got all pdf files I need and I will probably use your turntable module instead of the reversing loop. Which turntable does it use Z56 or Z60 ? I will try an reverse engineer it. Thanks for your help. Doug
-
Thanks for that - I have down loaded the app. and now able to view BSX files. I have started to build the loader but cannot determine which shock absorber it uses as shown on page 50 of the PDF instructions. Checked inventry file but its not shown. Unloader file shows two hard spring shock absorbers - is the loader the same. If so I have plenty from the Unimog set. Thanks for that info. i must have choose lucky as I used the old PF switch version has the small change over switch. New version with out the c/o switch has the friction dedents.

@plingboot @RohanBeckett Thanks for your help - have managed to download Bricksmith and open it OK. Its the parts lists that I cannot seem to be able to open. e.g. Parts-Siding.bsx FYI: I use Mac OS and now on High Sierra 10.13.4
-
Thanks for the advice - downloaded but my computer will not allow the app to be used as it was not downloaded from Apple Store !!! I will just use the PDF instructions.
-
Many thanks fro the info & advice re trans panels - don't have any so I have used black 1 x 4 x 3 panels with side ribs from lego trains. Hope they work OK with the unloader. Managed to build the motor module but don't have enough parts to build two motors yet. Looks like I will need to source many other parts. I like your turntable module and could use it in place of turn round track loop for the loader module. Is there anywhere you can order a set of parts for each module ? PS I can download the PDF instructions OK but not the individual instructions - I just get a load of code & my Mac OS asks for an app to open them.
-
Thnaks for the advice and info. Correction: My mistake - I have built the Type 2 motor module so will continue following those instructions. I don't have a lot of studded technic so will see if I am able to use studless technic beams / parts where possible.

Akiyuki Train modules. Type 1 or Type 2 ? I have started build this after hunting through my Lego spares for enough parts and so far have built the Type 1 motor module. However I notice that the Type 2 motor module is radically different as are the other type 2 modules in how the motor unit engages with loaders, switches etc. Which type is better to build and the more reliable ? I hope to build a simple system first and the add to it in stages. Also is there any info on how best to route PF cables to avoid snagging ? Doug72
