Scania 112

[Benni]

I came to the conclusion rather quickly that 6x4 would be a simpler solution, or at least forget the lift axle (for now, might revisit it later).
Getting rather excited to see it drive so the printer has been running almost nonstop for the last 48hrs and this is what I came up with

Don't know if there is a name for this kind of setup, walking leaf suspension thingy.
Haven't given up on making leaf springs but while still in testing phase it's easier to just print a pair.

Also put a little paint on a couple of parts, will need a few more coats and wet sanding to get rid of all the lines and imperfections.

The colour isn't exactly what I wanted but still pretty close. It's a standard rattle can colour and only 5min away so I'm rolling with it...

Well, I took the plunge.



Since I wasn't happy with the progress of scratch building everything as my first build I ended up with buying a kit, Tamiya Grand hauler.
Not that terrible expensive and the length suits my needs.

I also ended up on drawing up the frame and crossmembers in Fusion360
https://cults3d.com/en/3d-model/game...d-hauler-frame <- Link if anyone wants to check out.
Just to make everything easier in the long run since I want to put my own dup bed and cab and don't want multiple holed all over the chassis.

Nice, looks like that really speeds up build time!

I think there were some places that sell blank frames and printed drill-jigs, once you get all they layout finalized

[Benni]

Building the frame took almost no time at all, when the body came things started to slow down a bit.

Since I'm not running the original body I didn't see a point in going forward,
might put it on another vehicle in the future...

Now for the biggest (so far) deviation, the original truck has a flat floor but with the gearbox in place that's impossible.
But the good news is that so far I haven't had to drill any holes to the frame, I've been able to utilize the ones that were.

The stock Tamiya wheels vs my own design

Not by any means perfect but it fits my vision. The "Wire brush and a rattle can" look. Wish I had a resin printer to get a better finish...

The last few days have been quite exiting. (And also a bit disappointing)



A lot of testing, breaking stuff, redesigning and I've managed to get myself a working model that can be used in in light yard work.

This is still far away from being complete.
The body sits too low,
need limit switches,
the dumper lift mechanism needs rethinking, (hydraulic?)
electronic overhauling,
gear reduction,
and a whole lot of cosmetic details.

But before I can do any of that I need to fix my 3Dprinter, managed to fry the mainboard.

Fried printer huh??? I'm not gonna ask if it tastes just like chicken.

You're not alone though.... A couple of years ago I managed to static zap the input board on my Monoprice clone of a Wanhao D6. Now I never touch any of the electronics on that machine without first touching the metal frame - since it's grounded.

It was completely my own fault, was measuring voltage and the probe slipped and touched 2 pins...
But hey, always look at the bright side of things, this is a good excuse for a upgrade Just not yet.

[Benni]

Wow, it's been way too long since last update...
The progress here has been really slow for the last few months, but slow progress is still a progress...

A bunch of small upgrades, mostly cosmetics but also a few functional ones.
Biggest upgrade is the dumping mechanism, it now tips a descent load without any help although it really struggles in the beginning. Haven't ruled out hydraulic but would like to try out few options first.

We've had some amazing weather here lately.

Must have done around 100 trips in the last few days.
With increased weight comes new challenges.
Increased load on the front tires, especially with sharp turns, managed rip the tires (glued) off the rims.
I also ended up breaking some teeth in the middle axle, nothing catastrophic, managed to put the diff back together in a fully locked state which has had a little effect on the turning radius.
have also been thinking about this option

I'm off, back out in the sun while it last to do some more testing...
