Leonardo da Bricki Posted December 1, 2017 Author Posted December 1, 2017 Just now, Jurss said: Ar those suspension arms connected (top and bottom)? Seems no. If so, lower part will pop out of the hub. The thing, that holds steering gear axle in the front will not hold it in vertical direction. Ok, there wont be much load, but ... Yes, they are connected. But in the photo, I had forgotten to add the connector to the right side, as you can see. Concerning the 2nd part, I have already addressed the issue. UPDATE: Front Axle Had some time tonight for more work, so I again altered the front axle. It is now sturdier, and has some more details, including the fan and the lights. I will now move on the rear axle, fake engine, and gearbox, as these components will determine the shape of the chassis I connect the front axle to. After that, I'll add the rollcage and whatever else I'm forgetting at the moment. [WIP] Ariel Nomad Axle 3.0 [WIP] Ariel Nomad Axle 3.0 Quote
1gor Posted December 1, 2017 Posted December 1, 2017 It looks like front axle is indeed sturdier now, but still reminds me on formula offroader Quote

Leonardo da Bricki Posted January 20, 2018 Author Posted January 20, 2018 Hello again! I am back, with a very, very, VERY much overdue progress report. I am sad to say that I have not figured out a way to implement uneven arms in the rear suspension for this scale model. Perhaps in the future, a larger one, scaled to 98mm Unimog tires, perhaps with Claas tires (sand tires) on the rear axle, would work. A few photos below of some of the designs I tried. As you can see, even a half-stud offset is just too much, it keeps the wheel at an angle all the time, not just when the suspension is compressed. Failed Axle Failed Axle Compressed Now, I have begun working on a shifter mechanism, and adding the fake engine above the axle. In the real Nomad, it is chain driven, and I believe I can implement that here. I never realized until now how much more space there is when you don't need a battery box or motors. I could get used to this... [WIP] Ariel Nomad Axles 4.who knows... [WIP] Ariel Nomad Engine: Straight-4 Quote
1gor Posted January 21, 2018 Posted January 21, 2018 (edited) Suspension looks good My suggestion my friend - try to implement bricks like on Mack at both engine sides, sunce you chose to install smaller fake engine Edited January 21, 2018 by I_Igor Quote
Leonardo da Bricki Posted January 22, 2018 Author Posted January 22, 2018 Been working on the gearbox design, many thanks to DGustafsson13 on rebrickable for the original design and gear ratios used here! If you're here on EuroBricks, come take the credit! As for a shifting mechanism, well, it's a lot harder for six speeds... I think I have way to do it though. Kind of. One problem is the size of it. As you can see, it is incredibly bulky. And I don't know how to shrink it. As for the second problem... easier said then done. I'll explain more with the photos below. [WIP] 6-speed Gearbox As you can see... It's huge. Aquaman for scale. Keep in mind that most of the frame is 100% temporary, and can/will be changed in some way at some point. [WIP] 6-speed Gearbox Bottom view. As you can see, I have a mechanism for sliding the red shifter back-and-forth, however, it doesn't reach as far as it needs to. To work properly, it would need to move around 0.75 to 1.25 studs farther, side-to-side. I'm not sure how to solve this problem. Before you mention, yes, I am aware the red shifter is locked, it's simply to hold it in place while I'm building. Oh yeah, Lego, please make an 11L link! @I_Igor I am still not sure how it's going to fit in above the axle, so we shall see if it does get bricks around it. Quote
suffocation Posted January 22, 2018 Posted January 22, 2018 Have you checked out @Paul Boratko's 5-speed-plus-reverse gearbox? It's considerably smaller and runs very, very smoothly. Not sure he's made the instructions for it public domain, though. Quote
Leonardo da Bricki Posted January 22, 2018 Author Posted January 22, 2018 @suffocation I don't think so. Do you know what topic it's posted in? I can probably RE it if the photos are good enough. Quote
Leonardo da Bricki Posted January 23, 2018 Author Posted January 23, 2018 UPDATE: I have been tinkering with the gearbox a good bit, and there is no good way to make this design smaller, at least not that I have found. So I am going to change the gearbox a bit, and try to add a reverse gear, to be a bit more realistic. The actual Ariel Nomad has a 6+R gearbox, but that would a pain to try to make. A 5+R is good enough for me, plus, it will be smaller overall then the one i am currently using. I'm slowly getting an understanding of how this works, so here goes nothing. I'll add photos later tonight, if possible. Quote

Do you know what topic it's posted in? I can probably RE it if the photos are good enough. I suppose it's the non-AWD version of his 5+R gearbox, which can be found here. There is also an AWD version. Instructions for both are 10 dollars. He used a modified version (4+R) in his 1969 Camaro SS. There are some good images of that gearbox on this page. However, I think even a 5+R gearbox is overkill at this scale. It would be unproportionally big compared to the engine, which is very nice btw. I would settle for a 3+R gearbox.

I am starting to agree with you, because even though the gearbox is now much smaller than before, I still have no good way to add a shifting mechanism to it. 3+R, though it's less accurate, would probably be the better way to go, as I can then have a center console shifter that's (almost) to scale. I'll work on that today, see if I can get it done... 2. Thanks. I just wish there was an easy way to mount the engine, since there is no room to have the chain drive running from the axle... I think I have a way to make it work, but that won't come for a while. I need to complete (start) the chassis before that. Quote
Leonardo da Bricki Posted January 23, 2018 Author Posted January 23, 2018 Got this done in my free period, a quick-and-dirty 3+R. More later tonight. And I forgot Aquaman for scale. [WIP] 3+R Gearbox Quote
Leonardo da Bricki Posted January 24, 2018 Author Posted January 24, 2018 UPDATE: I screwed up the gearbox... I was messing with the gearbox, trying to add a shifter to it... And I realized I have the gears out of order. 1-2 on one side, 3-R on the other. Crap. That doesn't work. Currently, I'm working on another version of my 3+R, hopefully I'll get it right this time, it shouldn't be too hard, I don't think.... Just need to have a central output driveshaft for this to work. Quote
Leonardo da Bricki Posted January 24, 2018 Author Posted January 24, 2018 UPDATE: I'm still stuck. Here is what I have now, but I still cannot get the proper gear sequence. With the red input, the first gear on that axle is reverse, and then first. Please, @Didumos69 do you or anyone else smarter than me want to help me and point out what I did wrong? 3+R Gearbox V1.1 Aquaman for scale. It's pretty compact, about ideal size for my Nomad. 3+R Gearbox V1.1 Quote
Leonardo da Bricki Posted January 25, 2018 Author Posted January 25, 2018 UPDATE: Gearbox done, connected to the drivetrain and rear axle. Figured out the gearbox on my own, it now shifts 1-2-3-R sequentially. I'll be adding a shifter mechanism soon, you can see the attachment points for the red levers below the driving rings. Before I finish that though, I'm working on adding the fake engine above the rear axle. [WIP] Ariel Nomad Quote
steph77 Posted January 25, 2018 Posted January 25, 2018 Agreed with Jurss. If you do not links the two suspention arms this Will not résist. I realy appréciate and looks forwards to this project Quote
Leonardo da Bricki Posted January 25, 2018 Author Posted January 25, 2018 @steph77 I solved that issue long ago, the entire front axle module is complete now. It will be added in a week or so, as I will be building the rest of the chassis soon. Quote
Leonardo da Bricki Posted January 26, 2018 Author Posted January 26, 2018 QUICK UPDATE: Fake Engine Been working on this for a while, red pins+beams is temporary supports. Mostly just planning out connection points here for the suspension, and where to mount the engine itself. [WIP] Ariel Nomad [WIP] Ariel Nomad I won't have another update for a couple days, Great Brick War is finishing up Campaign 5 this weekend. Middle of next week I'll post something on this project. Quote
Jurss Posted January 26, 2018 Posted January 26, 2018 Isn't that suspension too wobbly? I'm afraid, that under load it will also broke, especially because of that lower connection of shock absorber. Gearbox is nice. Why You are making really fake engine? It seems to me, that it will look to small for this scale. Quote
Leonardo da Bricki Posted January 26, 2018 Author Posted January 26, 2018 @Jurss Currently, yes, but only because I have no real supporting structure. Most of that is temporary framing for sizing things and working out the upper mounting point. Thanks. Took some work, but I'm happy with it now. It's either going to be huge (9+ studs wide) or small. And I think it's pretty close to scale as I have it planned. Either way, I'd like to have one in there for sure. Quote
Leonardo da Bricki Posted March 28, 2018 Author Posted March 28, 2018 Well... It's been two months without an update. I apologize. Now I will rectify that problem. UPDATE!!! FINALLY!!! IT'S BEEN SO LONG I TOTALLY FORGOT THIS EXISTED!!! BUT THERE'S AN UPDATE!!! 1. Though I have no photos of it & it's already been dismantled, I did make the engine work. However... It needed to be about 4 studs shorter. So I decided to do without, and make a more detailed mock-up of one. 2. I have been working on a bunch of random bits lately, hopefully in a few days, I'll have something coherent to show you. Or maybe tonight, depending on how this goes... Quote
1gor Posted March 28, 2018 Posted March 28, 2018 we will survive day or two to see your update, don't worry. I haven't post my model updates for almost half a year... Quote
Leonardo da Bricki Posted April 5, 2018 Author Posted April 5, 2018 FINALLY!!! A REAL UPDATE!!! 1. THE GEARBOX: It is complete, and the extra bits to drive the now-long-gone fake engine have been removed. A shifter is still WIP, as you can see. I have looked at so many different versions, styles, and ideas, I have no clue as to whether this is replicating someone else's... As far as I know, it is/will be an inspired original shifting mechanism. [WIP] Nomad Gearbox Assembly 2. THE CHASSIS: All over the place. Most of it is just temporary right now, I'll be changing colors and streamlining it soon. Currently, it is just there to hold all the parts in place. [WIP] Nomad Chassis 3. THE BODY: I still have no idea what might happen with it, but it will most likely be integrated with the chassis so that it functions like the real thing, and provides strength and support. I will be using a few flex-axles to achieve some curves, sorry @Didumos69, but most of the body/rollcage will be rigid. And how about some BLUE seats?! Quote
Didumos69 Posted April 5, 2018 Posted April 5, 2018 (edited) Nice! The shifter looks a lot like this one... Edited April 5, 2018 by Didumos69 Quote
