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.

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

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.

hi. i'm back from holidays :D

Next step was the articulated joint:

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