    After more than a year without trails,finally did it!!

    Took the JK, the M548 and the ‘mog to drive a little. Ended driving the Unimog a lot more than the others

    Tried an easy line with sucess and was doing slightly harder lines and the truck was doing great…ended in one that I was positive that will fail…but the truck managed to climb. In 1st gear of course

    Those axles are seriously amazing.
    That 1st pic outside, wow.

    Thanks guys!

    well, to the news:

    that previous axle sparked an old idea of making 100% printed axles. About 4 years ago I worked on that, having housings printed but the big scx10 internals didn’t allowed to do them small and nice. Fast forward to the present and adding to my improved 3d skills,we have more choice

    Someone suggested TRX4 diff gears and using lockable diff. Was a great idea but the parts are too expensive.Remember that I need 4 sets to make 3 axles. Went to scx10.2 gears from Ebay and they seem good, nice machining and finish

    The issue was doing the gear mesh because of the “high pinion” feature but after a few tries, is done

    Doesn’t seems but it works:

    I’m aiming for this,2 halves:

    The angle on the pinions is because torque tubes are a possibility. I’m just waiting for parts to arrive to confirm if it’s possible

    Thanks! i try my best

    I wanted to do a smaller pumpkin because it just looks better. There’s quite a difference between scx10 and scx10.2 gears:

     

    Is 11mm actually because because of the design I’m trying to replicate, mine wouldn’t be 11mm smaller…

    Hi,

    This is taking more time and thought that I’ve expected. Torquetubes are cool but now I’m seeing why I only saw one project with them. There’s a couple of things to consider. Anyway, managed to print the prototype for the front axle. I’m still waiting for the other diff gears and bearings to arrive

    There’s the torquetube and the next thing to do is the spherical chassis mount…but need to center the transfer case outputs first. It’s not a problem with normal driveshafts but if the axle diff is centered,so must be the transfer case

    Did the skidplate and mount the transfer box as centered as I could. The torquetubes require that. The skidplate sits lower than the older one but I think that wouldn’t be a problem, this is a scale truck afterall

    Quick mockup:

    Missed the torquetube length by a couple of milimeters but the real ones will be machined from aluminium so it’s fine

    The rear trackbar mounts are in place. Need to redo the motor mount and wait for the diff bearings to arrive. My plane is to complete and mount an axle before moving to the next one

    Hi!

    Quite slow but I don’t gave up on this. Even if it’s harder than I thought….(so that’s why few people try to do this…hmmmmm)

    Still waiting for bearings and better filament to print the axles but in the meanwhile, did a new motor mount because the old one will interfere with the front torquetube. Speaking of torquetubes, started on the definitive ones, printed one at first to confirm the length and if everything worked.

    So, now in aluminium:
