This gearbox was harder to mod than the other but works well(minus the gears made of butter)
Turned my attention to the tailgate now. Added the steel tow cable with all it's mounts
Sure it will look better all painted(and without excess glue) but i want to show it earlier. For the curious, there's aluminium for the half circles and hooks , copper on the middle mount, brass on the cable ends and the cable itself it's steel(a bike brake cable)

Another stage:
Working on the ring mount and legs for the .50.It's a notorious feature that had to include..
The ring it's a 2 piece part that I've machined earlier. Could do it in 1 piece but this way, rotates 360º.
First, the front legs
Then,could do the rear ones
The asymmetry on these is on purpose.For some reason the 1:1 it's like this...
Waited to next day to allow to epoxy to harden and added reinforcements,steps and cleaned the "welds"
Only needs a bit of sanding,colour and better looking(and shorter bolts). I think I'm doing the .50's mount next...

While i wait for my m548 to return from the seamstress I'm doing other stuff. One of those are taking care of the tracks. Stock, look too clean and being all black,don't seem scale. So i tried to weather them to look metallic and worn
this is the first one, used a rust red, and 2 different grays
because the red was too "red" for rust, on the second track applied a bit of dark brown and seems better

My attempt at a canvas for the bed
About the random wiring and unused holes,the hooks don't have even spacing between them so i add a couple more holes for keep them even spaced. The eyelets are 3m and had to modify the plier to that small size. The canvas it's not green but i've seen them this color on some photos.
There's also a tarp for the hatch in the roof

Thanks!
Now, the suspension system:
The m548 uses torsion bars as suspension system with additional shocks on the first and last wheel
Not a m548 but you get the idea
On a m113
the traction bars rely on long rods that are fixed in one end and can twist to provide suspension. Many small cars still use that as rear axle.
After some research and failed attempts, decided to replicate the 1:1 as good as I could
Prototype:
These pieces are where the axles and springs are mounted
The photos are a bit confusing but the 8x 4mm rods are the pivots for each wheel and the wires are spring steel, later switched to a kind of spring blade
The advantages of this system are that can be easily adjusted in stiffness and ride height
Unfortunately, the first wheel on each side cannot be included on this system because the motors were in the way. The solution was putting a shock on the outside. Don't look out of place as the 1:1 has one too
An funny feature it's that, by the design of system,with torsion bars next to each other, wheels are slightly offset from one side to another. Hard to notice but the 1:1 it's also like this

The suspension arms. The real ones are a kind of dogbone so have to do them similar.
They are steel bar with one washer welded at each end to add that 3d look and help to round the ends. Machined a bit on the center to make it thinner. Then, filed all the edges to look a cast piece. On the holes at the ends, will be a axle for the wheel and on the other, the suspension pivot
In the end, they'll be almost invisible. Half-hidden by the wheels and the tracks
Doesn't show much...

4 arms in place
4 wheels in place
Only 4 wheels per side in that photo. The first pair of road wheels have a different suspension setup than the other ones. Settled on a simple design. A pivot bolted to the chassis where the arm rotates(ball bearings) and a shock. The 1:1 also has a shock on the first arm, assisting the torsion bar, so this it's not unrealistic
Mock-up:
Not happy with this shock so I've made my one:
It's an axial scx10 shock, gone from 93mm to 62mm,53mm compressed and 71mm extended. Shorter shaft and a "cap" hidding it to look more scale. On the next post, I'll show them mounted and a video of it working

Nice work on the suspension!!!

Thanks maus45!
more small stuff:
Take a aluminium welding rod
Hammer it a couple times, bit a filing and sanding and voila:
what it could be?
This is my first try with 1.5mm spring wire on the suspension:
Seems good but the steel don't return to the original position. A retired machinist gave me today a couple meters of spring steel in rectangular profile instead of wire. Gonna try that out
