    Wow! That's a heavy rig.

    No wonder your springs were breaking. Nice job on the recoil stock...

    Yeah I knew she was going to be heavy.
    I like the fact the weight distribution is accurate.
    The 1:1 tractor is about 32,000 lbs, and the trailer section is 17,000. The correct comparative weights help the realism of the driving characteristics

    This morning activity, I bought the cheapest driveshafts evar to put this together. Instead of splines, itís a D shaft, which means if you have torque applied, it wonít slide due to binding and then it pops out the cvd cross pin.
    So Iím upgrading to the second cheapest drive shafts, Ďnese punisher copies. They have 6 splines, and need a little filing to slide smoothly, but for $15/pair theyíre fantastic.

    I had to lengthen one for my main prop shaft. This runs from the transmission to transfer case.

    I started with a 10mm shaft I turned down to 7.5mm to fit inside the shaft. Iím adding 30mm to the length.


    The splines in the female side are only about 20-25mm long, the rest is round inside


    Looks like the length is good so itís off to the welder


    Welded, sanded, and installed. You can see another one I already replaced but had to shorten.

    So todayís project, steel reinforced fenders!
    I kept breaking the angles off the tractor and trailer fenders, so I cut out some stainless pieces and bent them up.


    ShoeGoo is a marvelous thing


    While I was at it, I used some old inner tube and made proper mud flaps




    I also had to test the new springs and drive shafts

    So I got new foams in. These are advertised for trucks over 10 lb. they are a two stage foam. The outer layer is still squishy, but the inner layer is firm. I got them into the tires today.


    Flat on the left full on the right.

    There is still a decent amount of squish but a major improvement in keeping the tread from folding over when pushed sideways.

    I finally got off my butt and got my wiring done. The articulation servos are now powered by a CC BEC at 7.2v while the 6v 5a BEC runs the radio and steer axle.

    Itís a success. The rig will articulate at a dead stop on carpet now.

    I got it all put back together. But a problem Iíve had is the crane was missing which sat on the rear bumper.
    I figured out how to get one though.

    I found a 1:144 scale 3D model of a hemtt about 30x8x6mm. Cut the crane off of it, and enlarged it 2750% to get the crane about 200mm wide.
    Then I fired up the printer


    Printing time with all the support structures is 32 hours.
    I have about 6 hours left as of this morning.
