I've been working on a copy of Akiyuki's mangle rack clock. I'm 90% there, but still have a few details to complete and some 'wrong' colours to swap. Otherwise it's looking good.

Is any one else working on this project?

I always wanted to try but could not figure it out from the video he posted. If you have any details or more pictures of the build I would love to try.

Been working on the Akiyuki Pneumatic trying to solve the jerky movements.  I had been thinking about this mod for a while.  The up down movements were pretty easy to dial in using the ever so touchy sliders.  So I thought why not adapt those to the rotation movement.  That worked out pretty well.  The only other issue I need to address is the rack that shifts just enough for the scoop arm to get caught on with weight in the basket.

nice work @Fyredog, the gear that turns the whole module arround is wrong in the instructions, it should be a 16 tooth gear not a 12, i made a file with the correct changes

Thank you,  Is your corrected file linked on Page 1 of this thread?

yes i believe so

i made a mini version of the akiyuki catch and release module:

Back in 2020 Akiyuki published his video of a LEGO cart with a mechanical direction switching mechanism.
I liked the idea and some months ago I decided to build a complete GBC module around this particular mechanism.
Later on I added a few more mechanisms by other GBC designers and ended up merging 5 modules into 1.

Hope you enjoy the video! :-)

New Akiyuki module! :)

 

Instructions can be bought here:

Sadly, quite the price hike over when he was selling the instructions himself.

Great to see him building again!

Hi guys. I'm new here, but planning a large lift build of multiple stacked copies of the Bucket Wheel Tower. But I'm finding some discrepancies between available instructions and their associated parts lists:

1. AKIYUKI'S BUILD

On Youtube at https://www.youtube.com/watch?v=10JQkulD-UI

No build instructions or parts list.

2. BLAKBIRD'S BUILD

Post at: https://www.eurobricks.com/forum/index.php?/forums/topic/117305-gbc-the-akiyuki-project-2010-2020/&do=findComment&comment=2391520

Instructions are at: https://www.bricksafe.com/files/blakbird/Renders/MOCs/bucket-tower/Akiyuki Bucket Wheel Tower.pdf

The parts list in the post is no longer available, but it is downloadable in .bsx format in this Bricksafe folder: https://bricksafe.com/pages/blakbird/Renders/MOCs/bucket-tower. However, the .bsx parts list will not upload to Bricklink due to invalid parts. The .io file is available, and Brick Engineering used it to output a parts list for me, but I am finding part quantities that don't make sense.

3. 9VSYSTEM'S BUILD

Post at https://rebrickable.com/mocs/MOC-94734/9vsystem/gbc-akiyuki-bucket-tower-with-descender/#details

No pdf instructions for those of us on Chromebooks, but .io file is available. And parts inventory is available at https://rebrickable.com/mocs/MOC-94734/9vsystem/gbc-akiyuki-bucket-tower-with-descender/#parts

4. BRICK ENGINEERING'S BUILD

YouTube video at https://www.youtube.com/watch?v=TAToSQuzXjQ

Associated Rebrickable page is no longer active. No parts list or instructions.

5. LEGO GBC NL'S BUILD

YouTube video at https://www.youtube.com/watch?v=tIDg-PF25f0

No instructions or parts list, but additional photos are in this Bricksafe folder: https://bricksafe.com/pages/Lego_GBC_NL/lego-gbc/bucket-wheel-tower-akiyuki-2013

THE DISCREPANCIES:

1. A Lego bar is used in the back of the bucket of Akiyuki's build, the instructions from Blakbird, and Lego GBC NL's build. But Brick Engineering's build, 9vsystems' build, and the animations from Blakbird show a 4M technic axle used in that position instead. The part inventory of 9vsystem's build does not include the Lego bars. I am assuming that the 4M axles work just fine at the back of the buckets in lieu of the Lego rods?

2. There are qty 4 red 3x5 L-shape quarter ellipse piece PN 32250 used in each bucket arms, which means builds with 6 buckets (Akiyuki, Lego GBC NL, Blakbird) will use 24 of them. But when Brick Engineering pulled the contents from Blakbird's .io file for me, it listed qty 38 of this part.

So in summary there appears to be several discrepancies in the Blakbird instructions vs parts lists vs animations.

I'm just trying to get an accurate parts list with matching instructions that will allow me to order all parts from Bricklink for this build, and then build it reliably.

It appears that 9vsystem's build has corrected some issues that were found during the build, so maybe I should go with that one? It's actually the only parts list I have access to, since I am currently using a Chromebook and cannot open an .io file while I am on travel.

Thanks everyone!

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. 

[Lego_GBC_NL]

Hi there, indeed my build is based on Blakbird's instructions and corresponding parts list (including the 4L bars). I still have the BSX file, but it's the same as what Jude just uploaded.
I don't recall making any mods to the original model, Blakbird's instructions are pretty accurate indeed and I had no performance issues at all with this module, runs extremely smoothly!
Only mods I made afterwards were needed to attach the spiral staircase output. I've seen several nice outputs for the Bucket Wheel Tower, Dunes' output indeed explains the extra 7*2=14 pieces (3x5 L-Shaped Quarter Ellipse Thin Liftarms).

Good luck with your build!

Thanks for the help.

Has anyone considered building the Bucket Wheel Tower using 28 tooth and 36 tooth double bevel gears instead of the 24 tooth and 40 tooth traditional Technic gears? They have the same axle spacing. I was wondering which combo might have the least backlash for a tall continuous build. Might try both and see.

I was wondering which combo might have the least backlash for a tall continuous build. Might try both and see.

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.

for the backlash issue on the gbc tower, i ran a common drive axle all the way up the length of the tower. this ensured that all the buckets were powered from the same drive and also keeps backlash to a minimum, like @Jude The Lego Dude has already said this is the best solution as if you go any higher than the 8 buckets the backlash gets really bad. i can reactivate that 4 bucket tower page if needed.

How often did you tap into the common drive axle?

i used the 3 drive points from the original version the bucket tower has about 30 pass points so putting the drives every 10 buckets works quite well, you may need to gear it down abit but i can hand crank the whole tower and the 5 modules which are also connected to the same drive very easily
