Hi model builders,
About a year ago I built this model truck. I started with a 1/24 AMT Peterbilt kit, but when it was done, I hadn’t used much of it. I kept the cab, and the basic engine, but the rest was scratch and aftermarket built. The front and rear axles, tires and wheels, and parts of the winches are from Kit Form Services.
To make it a 6x6 I made front leaf springs and suspension from brass stock and evergreen. The rear suspension is a combination of scratch and KFS parts, it’s a walking beam that is posable (that is, you can tilt the axles like the real thing). I used really small RC U-joints, so I could make posable drivelines, to accept suspension flex and not snap off.
I also added a PTO system that sends power from the transmission to the front and rear to power the various winches.
You’ll see the hood/bonnet represents the newer versions that Peterbilt uses, which was scratch built. Beyond this, there was lots of scratch work, gin poles and all.
It was a fun build - please have a look:
The interior of the cab turned out fine - but is hard to photograph. You’ll also see four shift levers, trans, transfer case, and front and rear PTOs.
This turned out to be a project that was as interesting to research as it was to build - lots about these trucks that I didn’t and still don’t know. Below you’ll see a few WIP images:
Above, you can see what I mean by “posable” rear suspension. I scrathbuilt a Hendrickson set up, and as you can see, it pivots as planned.
It’s a bit hard to see above, but I set up chain drives from the PTO to the winches - the chain drive is from a 1/12 scale motorcycle kit.
I did what I could to update the kit engine, firewall, engine bay, and spent too much time getting the steering to look right and remain posable.
And the hood - no fun at all - the version on the left (white) was the first try - close, but wrong, so, second try in primer - which is closer. The geometry of this is more complicated than it may look, and was certainly a challenge!
And there you have it - thanks for having a look -
Cheers, and happy model building!
