Jurss Posted January 8, 2022 Posted January 8, 2022 Got these parts. They are fifty shades of grey. No surprise, lego does best they can. https://rebrickable.com/parts/68327/wheel-41-x-15/ because seemed best for some roller. When it came out (2020), I thought, that we really could expect some road/asphalt roller. If not in technic, then in city or some other. OK, for city theme it is somehow too big, I suppose. When I started to build, I understood, that for technic it is somehow too small. But I managed to build something. Some asphalt tandem roller could be easier (will try that next), as I needed to find some matching wheels for rear. That was somehow challenging. But here it is (sorry, not the best pictures, as it is snowing in my photo studio), even with some functions - HOG steering, articulating roller, openable hood, and some really fake engine. I was thinking to implement some fake engine, but could not get together it with steering. Roller frame (or something) was also challenging. After some thinking this seemed best solution. On option was also 7x11 frame, in which those wheels fit really good, just it is even one stud wider. And then it doesn't look so good anymore and there are too big gaps between side and roller. HOG I put behind cabin, which mimics air filter as on some original rollers. Rear hood is openable, and there is very fake engine Quote
Maaboo the Witch Posted January 8, 2022 Posted January 8, 2022 Great stuff! Makes me wish TLG had done a Volvo compactor for the polybag set. Quote
jorgeopesi Posted January 8, 2022 Posted January 8, 2022 Nice design for and awesome tiny roller. Quote
SaperPL Posted January 8, 2022 Posted January 8, 2022 That's a really good use of those wheels. There are some details that could be done slightly better, but overall this is a really good model - great job :) Quote

Jurss Posted January 8, 2022 Author Posted January 8, 2022 I built it lego group style @SaperPL - You are free to anounce whole list Thank You all! Started to think about asphalt roller. Thought that I could use something like this but axles are too close to those wheels. Yes, that can be used as those roller cleaners (or something), but I can't use those axles to add connectors.

SaperPL Posted January 8, 2022 Posted January 8, 2022 12 minutes ago, Jurss said: @SaperPL - You are free to anounce whole list There is a steering wheel at this scale that can either sit on a stud or on a bar, which would be better than using gear. I think there is enough room to fit a driver seat, but I've got no idea if there is a good way to attach it. Also I'd try to hide every blue pin. The colouring could be a bit better if it was mostly yellow at the back and front and the cab was black, but the black sides at the back make it so that the black fake engine is lost in the black background. Black looks good as accents, unless the model is supposed to be a black car or bike, but big black patches a lot lead to hiding details and feeling a bit messy. And I've done a lot of this with prototypes, so I know the pain. Finally for a fake engine at this scale, I manged to do something really convincing with one type of connector: I think I've seen a lot of different approaches to fake engines at such small scale, but the way you've done it is not convincing to me, that it looks like an engine, sorry :P Quote

So maybe I was then littlebit lasy and just finished it. The same story is about fake engine. That was not significant for this project. And I could fit something that is 3L there, and it even sits on beam, which is structural element You mean this steering wheel? In fact, I didn't knew, that I have them :) Now I know. Need to find it. There are somewhere 3 of them in the house. Not in my sorted parts, but somewhere in kids room. Seat. I was thinking pretty long about it. There is pretty high already T-beam 3x3. Just side pins are free. Maybe somehow I could out in the middle this And then maybe I could fit some brick, there, that looks like a seat. Thank You for productive discussion! Quote

If you don't have the elements in specific colour and some elements for the engine, maybe you could build the model in studio and make the instructions for the perfected version? You have tested mechanical principles of the construction, so making an improved virtual model is not that bad :) Quote

You may use the pipes here, they are thinner and will not rub the drums. Only you will need to reinforce the triangles connection at the back side. Personally, they would work the best if added between the bigger outer frame (7*11) and drums to hold the "cleaners" and fill the gaps. I would dream about such roller as an official set if it has this frame Edited January 9, 2022 by Void_S Quote

As I mentioned before, I was considering 7x11 frame for that road roller, but it is somehow too wide. It doesn't look good with it. For some generic asphalt roller, just as standard lego set, maybe it would be OK. Quote

Jundis Posted January 9, 2022 Posted January 9, 2022 Nice little roller! I also like the built solution for the roller frame better than the liftarm frame. Side question: Why did you put this round connector piece in above the rear axle? Quote

Jurss Posted January 23, 2022 Author Posted January 23, 2022 (edited) Digital version. Added some front lights, some kind of seat. Also really fake engine is different. https://bricksafe.com/files/Jurss/veltnis/road_roller.io Edited January 23, 2022 by Jurss Quote
