Same love the small gearbox could you mail me some more pics of the small gearbox thanks agingles@btinternet.com

please could you send me instructions for the smaller gearbox, my computer wont open the link and it is ideal for my next project. i'm at ben.hunt.62@gmail.com

love your two gearboxs do you have any more pictures of the smaller compact gearbox as i would love to include it in my moc. i just can't get my head around how it is put together. if available could you post or send an exploaded view as this may help me and others assemble it. thanks

Haven't been here in a long while due to some intense working :) Firstly. Thank you all for those wonderfull comments that I didn't respond to yet :) Thanks for all of those that have added me to their favourite builders lists. You rock! :D I have updated the link to the LDD model, now it should work just fine. It's in the text right where it was before. Dear Jon. As to my gear ratio math, yeah it's kinda mixed up isn't it :) Still pretty simple. A gear ratio of 0.24 in my instructions means that every (1) turn of the input shaft causes the output shaft to rotate 0.24 times. If you want to get it your way just divide 1 over a given GR and you'll get the correct result (in this case 4,17:1). Ben. Although I've updated the link I've still sended you the instructions liked you asked. Daniele. I did noticed that :) Also a 6+R would take a lot less space (in height). It's 7+R just because I was building a Veyron :P

Your design is awesome! It looks that the first and reverse are on the same axle, but with small changes you can obtain a 6+R gearbox with realistic gears scheme.

hi I was just wondering if you could send me the instructions because when i click the link it says 'file not found' If you could that would be a real help. Im at 'ben.hunt.62@gmail.com'. I will credit your designs in my next creation.

Hey,awesome design but i gotta ask, i don't get the gear ratios , because unless you have 4 overdrive gears canyou resay what the ratios are for example like 2.77:1, that's a real ratio because it takes 2.77 rotations of input shaft to spin the output shaft once which is underdrive i kinda need help with your gear math ,kind of confused that's all .

You really have WAY too much time on your hands. Excellent work!... Did you say this was for smaller cars!?!?

ravishingly beautiful!

This is one of the best things I've seen on Moc. A compact, modern gearbox is usually one of the failings of Lego vehicles but this is fantastic. I'm going right now to make it.

Hey. I can't find the building instructions? When i follow the link from Josh Lucas, this comes up: Page can't be found. I use LDD, are there a building instruction for this? - Thanks

Wow! I just finished building this, and it is amazing! 6th and 7th are a little tough but still it is an amazing piece of engineering. This alone put you in my favourites!

really nice dude

I like what you did there... the only thing bothering me is the dislocated axle mount you mentioned... I don't imagine that to work very smooth under a lot of stress. While this surely isn't a gearbox designed for a R/C model, it's still a flaw that'd be cool to get fixed :p Keep up the awesome work!

very good job i like it smart and many funktions

I'd say it's about right for a 1:8 to 1:10 scale models. When it comes to mounting. Remember that what you see on the picture is a gearbox as a monolith construction (it even has blocks that are there just so it may stand properly). It is 9 studs high on these photos (without the handle). After building it around with some beams you can get the height down to 7 studs. I place the beams pretty much differently every time, what I most often do is building it oround with a square. Parpendicular beams on the front and rear - axles 2 and 3 go through them, and then i connect them together with two parallel beams. This forms the mantioned square. After that i form a custom mounting construction underneath this square to hold down axles number 5 and 6. -Its shape mostly depends on the number and placement of other mechanisms in the vehicle.

What scale would you say this transmission would fit into? 1:6 maybe? I have built it to try it out but I am not sure if it will fit properly into a standard 1:8 scale car. Have you tried building any mounting brackets to it yet to attach it to a frame?

Brilliant. You've moved the game on with this.

Absolutely brilliant! I'm gonna build it as soon as possible. I'm gonna by the parts via bricklink.com. It would be great if you could post a parts list. That would make the ordering much easier. It's brilliant guys like you that make me love mocpages.

OK I tweaked my LDD thanks to the instructions on the site You've linked. I checked the design, except the intentionally omitted parts, there is only one missing. Here's the tip which: http://img401.imageshack.us/img401/8484/errr.png . When You've posted the instructions I didn't even started to do my own :) Great thanks for the wonderfull job mate.

I checked the file here and was able to open it without errors.

Hey, I created instructions for this in LDD. Could you check to make sure it's accurate? I omitted the half-stud offset on the bottom axle on purpose, since it was unique to your implementation. If it's accurate, feel free to add the file to this page, but I would appreciate it if you give me credit for the instructions. http://mocpages.com/moc.php/210902

I didn't notice your comment that you were working on instructions yourself, but if you want to check mine, you need to unlock extra pieces for LDD by following these instructions: http://www.eurobricks.com/forum/index.php?showtopic=40794

Bravo! Jestem Zdziwiony! Bardzo Ladnie Wykonane!

so er.... what does it do then? it looks pretty neat but can you please make a comment about what it does?

Very nice, its good to see a new gearbox design

The only LEGO CAD software that I've used so far was the "SR 3D Builder". I've downloaded the LDD 3.1.3 (with brick version 114.3) and I'm not able to open the posted file with it ("Parsing the file was aborted due to an error in the file"). Is it an actual error in the file or is it my 'stock' LDD?

I've never seen such a small 7+R gearbox! I'm sure we'll find your idea in a lot of cars, because you explore a new way in the design of LEGO gearboxes! Good work!

Thank You. Regarding the offset gear I must agree with You. It just doesn't look right. Though I can assure You that it does work brilliant. I've checked how it works under various tensions and it actually does work under a double XL engine MOC with 0.67 engine to gearbox ratio, 2.67 gear ratio and 1.00 differential ratio with 4x4 drive and about 1,5 kg to move :) It just does not fail. Regarding the dimensions. This is not an creation under which I was working. I'm actually building a car and this is its gearbox (its a part of an creation and not an independant creation). The height and distances between the engine and offset axles was not suppose to be minimized :) It was supposed to be right :)

While this seems like a very interesting concept, That offset gear and axle just do not look right. This design may be compact width wise, but not heigth wise. I think if you worked on this a little longer you could make it even stronger. Still very cool though.

Woot! I'm stunned. An amazing creation. Nothing more to say... BRAVO MATE!

Some info can be found on my main page. As to my occupation. I work and study at the same time. Im a student of "Mechanical Engineering and Mechanics" at Poznan University of Technology.

Astoung piece of LEGO engineering! You got me to comment on a car-related MOC, and that's no small feat!

Thanks. And yes. I'm always connecting such creations to motors on different stages of the build. Just to make sure that everything works smooth. I didn't make a video since I didn't except such an attention :) I hope I'll have time to make the instructions and the clip still this week.

Very very cool, how old are you? I assume your a mechanic or something?

Excellent! A very complex MOC. Well done on that small amount of space! Have you tried to connect a motor on it? I would also like to see the instrcutions.

Oh My God! Man you just have to post those instructions. You've single handedly made me create My account! This transmission OWNS!

Thank you all for those flattering comments. I can see that actually a lot of other builders are interested in this designs building instructions and part list. No problem. I'll try to find some spare time this week, create them and post.

Very good work!!! The size is impressive... A part list an instructions would be nice. Can you create one?

awesome technic creation ,bravo

This could be a new era in Technic gearboxes.

It's now a long time I haven't seen Lego designing a large scale car built with integrated gearbox. I estimate the last time I've seen Lego doing this kind of stuff was in 1999 or 2000, that's 10 years ago. They should hire you to give a presentation as a 7-speed compact gearbox designer and insert it into their new large scale car model. Tomorrow it's the big day for me to present my Ferrari 599 GTB fous-seater sports sedan for a school course. I added two extra medium engines on te rear wheel to carry the scale car's weight. Now it has in total four medium motors that power the rear wheels and one medium engine that powers the steering compartiment. I think I'll have enough time to put the pictures and a movie on the site during the big holiday period.
