jgw Posted August 29, 2016 (edited) So, new update. A small one. There are some things that worked out well, and some that didn't. So, bad things first: The lifting boom does not reach low enough at all. I am waiting for a 13L liftarm, which will compensate the length by 4 studs, but even then it is to low. The problem is, I cant make the cilinders extend any further, since that will bring them over their "dead point". If the boom is then taken back up, the LA's will tare the whole chassis apart. The pendular suspension on the first axle is removed. This because I needed the space. I am running low on building space. The gearbox is taking up a lot of room, and the motors take the rest. The BB will be outside the cabin. Ugly, but the only option. The "X-frame" is not for sure a component of this truck. It's all about the space... Good things: The studded parts of the truck did work out very well IMO. I am not finished with the rear, but the side did come out very lovely. The gearbox and the LA's work very very smoothly, need to test the drive though. Still some poor, unedited photos Edited September 5, 2016 by jgw Share this post Link to post Share on other sites
steph77 Posted August 29, 2016 Hi i solved the problem of the arm action range on a truck i build some time ago. Go to my youtube Chanel to check if m'y solution can éventualy work for you. It use 3 actuators with on working in contrario of the two others.... Share this post Link to post Share on other sites

2LegoOrNot2Lego... Posted August 29, 2016 This is an amazing progress, looking all good so far! Sorry for the setbacks, but get used to it... :laugh: The rear impact guard is awesome, love all of it!!! Share this post Link to post Share on other sites
jgw Posted August 29, 2016 Hi i solved the problem of the arm action range on a truck i build some time ago. You indeed solved it. It is a very very clever mechanism! But sadly I can't use it. Too little space for it... Share this post Link to post Share on other sites
jgw Posted September 26, 2016 (edited) Okay, a new update! This update is quite drastical, but worth it IMO. It is seen from my position a logical step. The project was in the end not turning out as I wanted it to be. Everything turned out very smooth, but then I connected the drive. The whole drivetrain was based on U-Joints, strangled in all weird positions you can imagine. This resulted in a very fragile drivetrain. The rear differentials were supported by 2 O-frames, but the scale made it so that I couldn't place a small turnable between them. So the weight of the rear of the truck pressed on a single 4L axle. Now all of you know this wouldn't work, and it didn't indeed. On top of that, I was not able to gear down the 2 L-motors, so the torque wasn't great either. I had to come up with a solution, and I happely did find it yesterday. I removed the already poor performing pendular suspension, Which resulted in one layer of space more. Doesn't sound much, but it fixed a lot! The drive is now going in a straight line. The LA's are placed one stud lower, which means that the boom performes lovely now, it can almost touch the ground! And, who knows, there may be some place for that container attachment, albeit manually. Got a new phone, so better pictures in bad light! Don't mind me in the window Let me know: big wheelcovers or small ones? Edited September 26, 2016 by jgw added pictures Share this post Link to post Share on other sites
