In that case, no, I don't understand either. In fact, if you made a small unthreaded shim on one end, and a corresponding indentation on the other, you could make one that was both stackable and a full 2L long. Maybe not enough diameter to play with on the 2L worm gears, but should be possible on the newer 1L ones, I think. Quote

But my question in the AMA was if you were willing to sacrifice the stackability, wouldn’t a perfect 2l or even 3l worm gear be possible? (The answer was apparently no, but I don’t understand why that would be so) Expand It sure seems that it would be possible if one were willing to give up the stacking! Quote
Johnny1360 Posted March 8, 2021 Posted March 8, 2021 Could it be possible they do it that way for some reason we are unaware of? Maybe it's like that to avoid interfering with other parts while in operation, or the other way around. Quote

Especially since you wouldn't want the shim to work itself into an adjacent axle hole. Quote

I’m not sure that would work.. if you then put 2 of those stacked worm gears on a rack the shim in between would cause it to be misaligned? I think it may be a choice between one or the other.

I think it may be a choice between one or the other. Expand No, my idea is that the shim would slot into the end of the next one. As @pleegwat says, I don't think there's enough diameter, at least on the 2L ones, and you'd only get a whole number of studs with a single unstacked gear. Quote

doug72 Posted March 9, 2021 Posted March 9, 2021 (edited) Re Stacking 2L worm gears. There is a right way & a wrong way to do this - see image. If stacked the wrong way the worm teeth don,t match and cause increased friction when engaged with gear racks. The groove seen between the teeth should all be in line to be correct.

samuelgu Posted March 14, 2021 Posted March 14, 2021 I would like help to make a lego technic nissan z32 in the style of bugatti chiron set. How can I do that? Quote
Gray Gear Posted March 15, 2021 Posted March 15, 2021 @samuelgu I am glad to see another JDM fan here! The 300ZX is very underrated imo. Do you have some technic MOC experience? Building a 1:8 scale cars like this takes a lot of time, especially if you don't have a lot of experience. First thing I always recommend is to work with Sariel's awesome Model Scaler. It'll help getting the proportions right. >> Model Scaler << Quote

Expand Well, considering how little those parts were used in their time, they probably weren't exactly greatly useful or at least they broke easily or something. They were only ever released in 2 lengths, 4 and 10, and only appeared in a handful of sets. Quote
2GodBDGlory Posted March 25, 2021 Posted March 25, 2021 I'd be quite interested in getting some, but they are rather expensive now... Quote

Expand I wouldn't go overboard for them. Nice to have in a parts collection for completeness but they soon work loose in use, 3/4 turns of 8851 turntable, and double nuts do not lock it either. Possibly why discontinued so quickly? Quote

Scoar Sonander Posted March 28, 2021 Posted March 28, 2021 Hi! does anybody have a solution for brakes for a rear axle, and brakes for a front axle? I see that lots of people use Pneumatics, but I am looking for something like the system that Sheepo uses... anybody have any ideas? Quote

I see that lots of people use Pneumatics, but I am looking for something like the system that Sheepo uses... anybody have any ideas? Expand I've done a number of cars with mechanical brakes. Here are some images of my most recent design: Bronco Sport Rear(https://bricksafe.com/pages/2GodBDGlory/ford-bronco-sport) Reveal hidden contents M-motor driving U-joints, driving bevel gears, rotating 2L beams, pulling 6L links Similar Hub from above. The black connectors with 3L axle are fixed on one end, and loose on the near end. This pulls black 4L half beams, pulling the rubber against the disc This is a poor image of the bottom of the hub, but it might help Bronco Sport Front Reveal hidden contents The 5L suspension arm in the center activates the brakes Bottom of the hub Unfortunately, I don't currently have any images of these hubs on their own. If you are interested in them, and can't figure it out from these images, I can try to rebuild them and get some better ones. Quote
Scoar Sonander Posted March 30, 2021 Posted March 30, 2021 (edited) OK! Thanks a lot, I hope you don't mind if I pilfer these creations and use them to my own ends... (I won't sell them, of course!) Edited March 30, 2021 by Scoar Sonander ton > to Quote

Scoar Sonander Posted April 8, 2021 Posted April 8, 2021 (edited) Does anybody have any tips for making a Lexus front grill, like the one from the RC? I've seen people just use normal plates, but I want to use this for 1:8 scale. Thanks in advance Edited April 8, 2021 by Scoar Sonander Quote
Jurss Posted April 9, 2021 Posted April 9, 2021 Maybe You can strech some lego net there? https://www.bricklink.com/v2/catalog/catalogitem.page?P=71155&name=String & Net Lattice 10 x 10 Square&category=[String & Net]#T=C Or use this https://www.bricklink.com/v2/catalog/catalogitem.page?P=30923&name=String & Net Lattice Plastic 8 x 14&category=[String & Net]#T=C Quote
Scoar Sonander Posted April 9, 2021 Posted April 9, 2021 Thanks, but those are relatively hard to find, let alone to attach! Maybe I'll just make it black and use stickers! Quote
