Excellent use of parts. Very creative!
-
i have a soft spot for hardsuits. Excellent work! Great use of those spring parts. If i could rate mocs, i'd rate this 11/10.

Nice looking fire bat..

I'm back in business. I got the package in the mail and got my differentials. Found a flat gearbox design from google search that i copied and modified a little. Pictures coming soon. I'm currently having two axles on top of eachother, one stud away from eachother.. Lower one for drive and upper one for steering. Can i get two functions trough the turntable by using the new differential? EDIT: The reason why i'm asking is because i only have the 42055 set parts to use. And i'm beginning to think that it's impossible to get drive and steering trough one turntable with these parts. I think i'll just have to order the turn table 2 function parts from brickowl.. -

Take a metal rod that's small enough to go trough that white axle piece and push the lego axle out of there. I use a toothpick. (Toothpicks are for single use only because they break.) -

I wonder if he'd like to share instructions how to make it. Two motors between the tires is the best setup for crawlers. Also the fact that you can switch from fwd to rwd or awd with a flick of a switch is awesome. (Push the front wheels up with RWD and pull the back wheels up with FWD.)
-
Man i love rc crawlers.. I think i should try building one.. I wonder if i could make a RC crawler with two XL motors..
-
I'm giving up on this project because the gearbox gets so low that it'll lift the tracks in the air. I'm going to switch from an excavator into making a landrider style tank. After i get the hang of making proper gearboxes, i'll retry the excavator once more. But it was a great learning curve. I just need to rethink this thing. Can't wait until i get my package in the mail. Expecting differentials and whole bunch of gears.
-
Thoughts? It's a gearbox that'll take one input shaft and turn it into two rotations in the same direction or two rotations in the opposite direction (after i attach the differentials to the front end.) Weakest link is the two gears on the sides which are only connected by a 3 stud length beam. So far, the testing has shown that it works perfectly. (The three long beams are just there to keep the gear selector in place as i figure out a sturdy way to connect it. ) This is a fun project. Imagine a car that'll have a gearstick that can only go forward and back a click. Then you have two pedals on the floor. Left pedal will go backward and turn to the left and the right pedal will go forward and turn to the right.

No wonder i was having trouble with my own custom gearbox.. I completely forgot these existed:
-
That looks cool. I could make it so the motor powers everything.

i'm trying to have one motor on the upper half.. The battery switch directions will move it forward and backward. And flicking a gear switch will change it from drive to steer and then the battery directions will steer it left and right. The upper half will be turnable by hand. I'm struggling how to implement the mechanism to the bottom half. Now when i think about it, i'd like it so i hold the model from the top half and use switches to make the bottom half move.. Rest will be hand cranked manually. (Don't have RC parts. Only got one motor and one BB for power functions..)
-
But how does that thing turn? I want it to be able to turn 360 degrees so i'm moving the motor and BB to the top half.
-
Update: Here are the tracks and center part.. I had to tear apart the transmission and restart.. But currently i have the center turntable and one drive axle coming trough it. Now i need to convert the one drive axle into two axles. One for forward and reverse and the other for turning. I'm using the basic subtractor scheme. But i'm stuck at how do i turn that one axle into two with a switch in between. That switch in image two was just a mockup to test it. The differentials and gears are coming in the mail shortly. So i'm currently mocking up a test gearbox and leaving space for the differentials. The tracks are a slight twist from the BWE track system. But it fits this excavator mock.. Any ideas or suggestions what kind of gearbox should i build here?
-
Should i just skip the nonsense and order a XL motor to the begin with? The excavator i'm building is going to be very large. Not 42055 large but close. The original plan is to have an electric track setup and fully mechanical arm on the top half.
-
Man.. Technic used to be hardcore. I can imagine the joy when kids got this set back in the day. Hours upon hours of fun.

Alright, i ordered 5 differentials and some other bits and pieces.. I have a new plan for this excavator.. It will have a V8 engine on the top half and the motor + battery will also be on the top half.. All the gearing will go down to the tracks in order to move them.. The big flaw in this plan is that i can't have two axles going down the middle so the tracks will only have forward and backward movement so it won't turn.. Unless i can make one shaft have two functions with a switch. Is it possible to make it so the engine spins when the motor is spinning in idle. And when i move a switch to the left, it'll move forwards and if i move a switch to the right, it'll turn left.. Then if i reverse rotation from the battery switch, i can make the left switch move the tracks backward and the right switch turn to the right? I think it could be done with these: EDIT: Here are my plans:

This is a very nice slizer reimagination set. 10/10. -
What's the difference between this: Open center or this: Closed center I'm going to order at least 3 differentials and some gears for my upcoming project and i was just wondering what's the difference between these two diffs and which one should i choose? EDIT: Also if anybody has any tip where i could find the cheapest order to get differnetials and other assorment of technic gears and stuff shipped to finland, i'm all ears. Currently i've been using brick owl and it's been a reliable site. Although the postage some times is just crazy.

Scale model = an accurate scaled down or up copy of a thing that exists already. Technic, mindstorm ect.. = Anything else. Best explained by: An engine can be a motor. But a motor can't be an engine.

42055 is the best starting kit for this technic hobby.

I'm currently in progress of disassembling the BWE and trying to put all the parts in labelled containers.. It's a big big job but it'll pay out later.. I'll probably order up differentials and a large motor + other misc parts like gears and stuff and do it right the first time. I have two of these filled up:
-
This will be an interesting project because i don't have those differential gear things.. I only have the parts that the BWE came with.. I'll just have to figure out a way to gear the thing with those parts.. I'm thinking about having the upper part of the whole thing completely mechanical. So the whole top part will be moved by levers and twistable gears.. But the bottom half will be controlled via one motor.. Other solution is to wait till i can order new parts and get the right parts that i need.. But then i'd just go with twin motors. So i guess this is just a fun little brain teaser project to get to know building with technic.. Before the BWE i was only a CCBS figure builder and now i'm stepping to a whole new scene with this technic bit.. I like a good hard challenge.
