![]() I will be re-visiting the worm drive because that did give a much higher reduction. The speed it runs at is going to make locating the MLP on launch supports difficult. There is no space in the drive train for higher reduction or extra stages in the gearing. I like that it has some good speed but it really should be slower. In terms of speed, yes that is going to be a problem. So yes, lots of things are on the limit of what plastic can tolerate :) The biggest challenge was the fact that the chassis is basically hollow, so supporting everything mechanically and keeping the look was a battle. There are so many competing factors going on here, it is one of the things that drew me to the project in the first place. ![]() I'm looking forward to see more progress! I expected it to be way way slower - actually don't you think you require to high speed out of this massive contraption? Probably pushing lego (and ABS plastic) to the limmits :D I'm honestly impressed with it's driving performance. It's cool to follow your progress, seing how clever engineering approach you take while solving the problems. ![]() I think I saw this earlier on yourtube but somehow missed this toppic until now. Even with a little play they have not skipped at all.Įnormous creation. The new bevel gears seem to hold together much better than the 24t crown gear. The m-motor axle is now properly supported and the gear ratio ended up the same 1:6. No more gear or part separation, right to the point where the motor stalls on a new set of batteries. Going back to the original bevel gear approach (which is a little closer to reality) and making a number of modifications has helped. I do like that it is so much slower but that's about it. I had to significantly modify the steering arms to get the changes to fit and that made them a lot more flexible and the list of cons gets longer. My bad for sacrificing rigidity for looks. It generated a lot more separation pressure so rather than limit the number of holes visible and use short 1x2 bricks, full length beams keep everything from separating now. Another issue is that I cannot run beams side to side and that allows just a little flex when the load comes on and the worm gear is catching on the Pole Reversers. This is only from a few minutes testing so I'm not keen to keep going this way. It is generating a lot of Lego Dust at each end of its axle at the half bushes because of all the thrust. Is there a LDD file anywhere? As I would like to see if there could be further improvements to the crawler assemblies.Īfter trying the worm drive I have a different set of problems.
