ravens s.o.f.t. – a brief summary

[Member raven62 Topics 12Replies 259Scaling Like A Pro★★★★★]

After a floatingcrane and a floatingcrane-pusher (or ahts ) I’ve started in september 2020 the build of a new offroad vehicle.

Based on a traxxas trx6 it should be a full functional firefighter truck. At this time, I didn’t know if it will run or a big fail. Due to some other reasons, I’ve forgotten this little beautiful forum.

My next project will start soon, and the s.o.f.t. is, in it’s technical point of view, a straigth predecessor of the upcoming project.

Thereby now a briefly summary of the last five Months:

All starts with a trx6 chassis

A firetruck needs a water tank.

The Hull should be completely from metal. At the articulated trial car I’ve used aluminium sheets. But I’m not really happy with this material. Meanwhile I’ve found a shop which sells 0.1mm steel body panels. Steel is very well weldable. But so thin sheets and a big weld-machine? After some research I’ve bought a Micro Welder from Lampert. A win – win for me and my wife, because my other hobby is making jewellery. The microwelder raises the possibilities enormous.

 

 

 

First bigger parts to weld was the cabin-frame. Not good, not bad. Much to learn and much to practice.

Looks quite good, but just the sheetmetal is too weak and I’ve decided to add a steel tube frame.

to avoid collisions from the fragile monitor with trees it will be retractable

Above the tank, the complete mess of pumps, electronics and the remote controlled filler nozzle take his place.

On this pic it looks very accurate, but this will change later 🙂

 

Pumps are: Monitor, Filler and Tire watering

 

The truck is a prototyp, so the cockpit interior wil by hypermodern with tft-screens and touch panels. Only the steering wheel is old school.

you really like challenges. There’s no margin of error with 0.1 metal…

Beautiful work Ralf, glad you’ve found us again. There is a tonne of mechanics and electronics in those pics you’ve barely touched upon.. I’m fascinated already

Hi,

the electronics are a great mess for just a short list of features:

retractable and turnable monitor

track and tire watering

automatic tank re filling

standards form the trx6 are the two gears and the lockable differantials

learning points for me during this project were welding and handling fine sheet metal , soldering smd-leds and programming an arduino to manage three little tft-screens.

 

.1 mm metal is really thin but meanwhile i love it. it s a specific alloy for chassis works i.e. pressing and deep drawing.

it comes as a coil and can cut with a sharp scissor. lexan sciccors are great for small curves etc.

 

If parts need a bit more stiffness like the bumpers, i’ve used the monstreous 😀 .2 mm sheets.

 

First big learning was, that welding steel-tubes is easy, but welding waterproof steel tubes is really tricky

I’ve invest several hours and tube-meters of testing ans learning.

But at the end, the tubes to the monitor are ready and the monitor gets his final form.

 

Some endpoint switches are added to prevent collisions

After a bit color the cabin began to look like a cabin.

 

Next step was the build of the rear hull…..

Building the rear hull. (Front part. My oven is to small for the whole hull)

 

a sheet of 0.1mm metal

 

 

lines

more lines

lines for some beads

beads

cut out

window to reach the main switch

completely folded

very wobbly and will get a inner reinforcement

So much talent and so much bonkers in one go.

I love this way of live. My Job is serious enough.

—————

Building the rear hull is done and a great orgy of soldering smd-leds and fitting all the little things together was following. Actually it waits for material of the track & tire watering. This will be the last work before a great testrun.

Some Instagram Links for actual Clips:

Little lestdrive in my garden during rearranging a pond.  It’s not a slomo. The hobbywing fusion 1800kv is a lovely engine to drive extremly soft and sensible!

At least a Still from the testdrive

Width: 24cm

Length: 70cm

Height: 32cm

Weight without water:  8,8 kg. (Very light for a car with a full metal hull, i think)

 

So, this Project is almost finished. Next will start in a Moment 🙂

Last feature is online. Track and Tire Watering to prevent melted tires.

For my next project I’ve needed the ability to bend tubes exact and reproducible in various diameters. (many people can this with their sense of proprotion, i need hardware )

The winding tube under the cabin for the track watering was the first complex bending-test. Not perfect, but works.

Following this on IG…impressive amount of work…you really like to learn new skills

[Member Paulnb57 Topics 2Replies 27Ready To Trail★★]

Enviable skills! Great build

Wow … What an engineering project! that micro welder looks like an awesome toy on it’s own … very mipressed.

Hi,
