1/10 Oilfield Truck Foremost Delta 3

Hi,
browsing around i've found pics from my very first complex steel build.
A Foremost Delta 3. Articulated steering, full functional gin poles and many other features.



If someone is interested on more detailed information of the little Monster let me know. They will come

Looks like a real beast!

Very neat truck.
Teaser like that and expect us to not want more info?

OK.

The build started mid 2016. At this time I owned a Proxxon Micro Mill, a Proxxon Table Saw and some handtools.
First experiences in metal handling were done, but in small sizes. Some hard soldering for tube frames were durable but not very chic.

After some research in the web i've found the "unusual locomotion" site. Looking for a Truck with angular design I've found the Foremost.
Some more research later i've get the tech specs and a small bunch of high quality pics.

For a 1/10 scale truck, the sizes are big. 3,3 m wide, 3,2m high, in the first version as 4x4 9m long.

Features are: Articulated Steering, great low impact tires, leaf suspension at the front, the rear axle is direct mounted on the frame.

I don't know anything about articaluted steering, leaf suspensions or the physics in this size category.

So, it was a very exciting journey through a lot of ignorance, learning, errors and retries.

All starts with the axles. Designated were two old moas axles from a axial xr10. I bought almost exact scaled tires. To get the target width i have to rotate the tires. So i need adapters for this.



The cut and drill these little plates the micromill was on their limit. But it works and i'm happy as i saw the monstreous axles

The front suspension are leaf springs. For this monster no springs are buyable.

First step are the holders for them.

Aluminium 25x10mm

some holes


sawed with the small tablesaw





ready for the springs

the springs are from


these tapes are easy cutable with a manual metal shear


drilling is more challanging, but at least its done


Bending and preforming was easy with heat. Spring steel losts his tension and you can form the eyes simple with pliers.

Preforming needs a support with screws in the right distance.



heat up and when its hot enough you can see the lost of thetension . after cool down the spring holds this form but is still springy.



mounted


with more progress on the cabin, some leafs will added.

hi. i'm back from holidays

Next step was the articulated joint:

Two pieces of aluminium marked


slotted


milled






holders









works fine so far


as you see, at this stage the plan was a 4x4.
