Back with another GBC module: this is inspired by a KNEX set called the "Clockwork Rollercoaster", though there's nothing really "clockwork" about that set or this GBC: Again, I'm not making instructions at the moment, especially when this uses a handful of old parts, but I can provide an LDD file for folks who want to play with it.

Ah, sorry for the late reply... I'm probably not going to make instructions unless people are willing to buy them, but I can send you (or anyone else interested) close-to-final LDD files if you want. DM me.

Ah, that's just so people with slower connections don't get hammered by trying to load everything at once... sorry if it was confusing! Yaaa... I didn't realize he had done some similar things until after I had made the respective modules. Still, I like to think of these as more accessible versions of what Aki's done. I'm a little torn on trying to research or not research other modules before building my own... on one hand I would like to avoid the influence of other designs in my own design, but on the other hand, sometimes the thing you think is original isn't.

Hmm, it seems fine to me, so it might be an issue on your end... unless other folks are having the same issue?

Thanks! Was super happy I could use those Bionicle liftarms too

Thanks! It was definitely on my mind to try to build both unique and minimalist for some of these while I'm building up the parts inventory to do more involved modules.

Hello all, I recently started building GBC modules and wanted to share a few original/semi-original modules. Split-level Stepper Extensible Tower Not-Scissor Lift Some perhaps fancier ones to come soon! Bonus:

Thanks guys, someone asked for the LDD file, so I will add it here: http://www.brickshelf.com/gallery/BradlyColin/Miscellaneous/gbc/190328a_gbc_train.lxf (The heights might be a little off, but they should be easily adjustable)

Something different for once...! Ever since I bought a used 7722 a few years ago, I've been wanting to use 4.5v train/Technic stuff in a contemporary application. Originally I wanted to build an Actual Train Thing, but my Bulleid Leader has not worked out, at least not in a 4.5v context. Recently though, @jtlan and I have been getting into GBC, so of course I had to shoehorn the 4.5v train in there somehow. Anyway the Simple GBC Train has a bunch of mechanical features which are better explained in a video: For those of you who don't know what GBC is: http://www.greatballcontraption.com/wiki/Main_Page Anyway, I put this in Train Tech because while it is GBC related, I think it's more train than Technic. Furthermore, GBC might be the intended application, but this system could also be used for other automated train loading/unloading sorts of things if you are into that. No Brickshelf gallery as there's not really much more to see than what's in the video, but I can provide a LDD file if anyone is interested. Otherwise have a nice day!

Dunno if anyone is interested in this sorta thing, but some commentary on drive train revisions on older MOCs... been doing a lot of this sort of thing in the last year. A lot of times when I do a new build, I don't know what the issues are until I run the engine more often and for long periods of time, and only then can you even start to debug or make improvements. Building a new powered tender for the T1 Changing the gear ratios and motors on the QJ Have a nice day!

That would be too easy

That is indeed my T1! ... it's roughly the same scale. You can see the original thread from 2014, though it has been updated a bunch since then!

I do have the unicycling lion... I think? At least this was what I saw on someone's model... though whether or not that model was accurate, I'm not sure I don't want to mod the 4.5v battery box car, so point to point will probably have to be for a future (smaller) model, but it is still on my bucket list! This one will probably get converted to PF (or maybe powered up!). One thing you can do with the 4.5v motors is wire them in series and then run them as pairs off the PF controller via the 9v extender/adapter. That's probably what I'm going to do if I want to keep the 4.5v motors in this loco, but they need a lot of gearing down and so far I haven't found the space to fit the PF battery box and receiver without compromising structural integrity. I'll definitely update the thread if I get around to it though.

Hello all, long time no post! This project is kind of a wash at this point, but I think it is still worth a share. Perhaps that's appropriate as the SR/Bulleid Leader is best known for being a total flop, an unconventional design with a lot of new features that of course proved too complicated and unreliable to even see regular service. Five of the 0-6-0 + 0-6-0 articulated locomotives were laid down, but only one was completed, tested, and deemed unsatisfactory before the whole lot was scrapped. I usually only build American trains, but I make exception for the Leader as I have a fondness "advanced steam" designs like the ACE 3000 and the 5AT. Also like the 5AT, I had built a mediocre model of the Leader a long time ago and wanted to revisit it... Like almost all of my train models, the Leader is built at roughly 1:48 scale, and the chassis can navigate all the normal LEGO R40 track geometries. At this scale the locomotive should really be 7-wide (as should most British engines), but I fudged it and made it 8-wide such that the body would not be wider than the trucks, which I could not narrow due to the huge greebles on their outside frames. Also due to the trucks I had to compromise on the lower line of the body: the prototype has a very long sweeping curve over the two inner drivers, but I could not get enough clearance between the wheels and the cowling to make this work on R40 curves, even with the pivots right next to the center axles. For now that line is just abbreviated, which is sad. The roof has a bit of a hodgepodge of different curves. The 2x8xN bow is a good approximation of the actual look, but I had to use other combinations of parts to model the various features on the top of the loco. I think the mix of implementations does a good job defining the shape but also giving it some texture, though there are some cracks especially around the bunker that possibly could be smaller. Moving on to the internals! This model has a pretty unique drivetrain and this was one of the main reasons I wanted to build it: when I bought a used 7722 a few years ago, I noted that the 4.5v system had a feature that has never appeared again on any subsequent train system, and that is the ability to run a train point to point** I thought it would be really cool to build a nice model that could leverage this functionality, but it would have to be a locomotive that could realistically pair with the two-axle 4.5v battery box, so revisiting the Leader seemed like a good choice. Furthermore, I wanted to try out an interesting articulation mechanism for the Leader proposed by fellow builder @jtlan, which would theoretically work well with the large outside frame greebles. Unfortunately it's this 4.5v drivetrain that really hasn't worked well. It seemed to work fine in the ample testing I did prior to finishing the model, but the shell turned out to be really heavy, and the motors have trouble moving it at a meaningful speed while pulling a meaningful train. You can see some of the test beds and the final product in this short video: Ultimately, I've tried to tweak it to no avail, so this will probably have to be converted to PF for it to work well, and I don't really have that much motivation to do that as 4.5v was the whole point. So for now, that's that; there are a few more pics once the Brickshelf folder is moderated, but otherwise have a nice day! ** What I mean by point to point is in the video at 0:10

Yeah, I'm aware of the previous posts... someone contacted me trying to get the file, but I don't have the original anymore, so I was hoping to be able to get someone to recover it from that post. If that's not possible, oh well.
