Autocar ACX 8 x 4 Cabover

[Jürgen M.]

Hi everyone,

I'd like to share a build with you.

It's an Autocar ACX 8 x 4. There's no such model kit? Probably right. Thats why I'm designing the parts and printing them on a 3D printer.

There's not much to see yet though.

I've made the cab and interior by now! 

The chassis is in production.

Here you can see the first few parts, not painted yet though.

Hope you like the idea. There's more to come! 

And this is how it's supposed to look: (Pics from the Autocar website).

I may vary in the choice of colors and perhaps cut some details though! 

I'll be back soon with more parts and build progress.

Fascinating stuff, looks like a municipal chassis, garbage truck etc... Are you using an Autocar chassis? I don't suppose it matters really does it?

[Chariots of Fire]

Nice work!  And a unique choice for a truck build.  Rockford is right.  Typical US trash truck chassis but perhaps without the second steering axle.

Cool! Nice work on the 3D printing! I see something similar going around here today, it's garbage day!

They really are good looking trucks and they keep them clean

[Jürgen M.]

Glad you like my choice! 

I won't make a garbage truck out of it though. I haven't decided yet. 

One thing's for sure: the steering will work in both front axles. 

Thought I might make a cement mixer or a mobile crane or something.

Here are the first chassis parts:

Front suspension is being printed just now!

a cement mixer or a mobile crane would go really well with it since you have two steering axle's, but if it were mine i would go with the mixer...

Thanks for your opinion! ?

I think it would bei a challenge to design and print that! ?

 

[Jürgen M.]

Thanks by the way for the picture of the original Autocar. ?

here´s a little something to see. It´s the printing process of the front suspension:

Excellent work so far 

Looking forward to progress 

[Gary Chastain]

This is a build worth watching. 

[Jürgen M.]

Thanks guys! 

I'll show you some progress on the chassis later. 

Didn't have much time today, too much work!

But what are evenings for? ?

[Jürgen M.]

OK, here´s a bit of progress on the chassis:

I had to exchange the front axles since they kept breaking. I put in metal pins. Also the vertical steering axles are of the same metal material. It´s just safer that way. wouldn´t want to take everything apart if something breaks. But the steering works. Still have to combine the steering of both front axles. Might have to improvise a little.

 

Thought I´d also add some pics of the 3D designs:

Got some new pics to the chassis progress. Not much but it´s getting there!

 

 

 

[Gary Chastain]

Outstanding 

[gotnitro?]

fantastic work on the chassis so far !  watching the printing process is very interesting

[Jürgen M.]

A little update on the chassis:

 

 

[Rockford]

Very clever stuff, looks great! 

[Jürgen M.]

Wow, I'm really happy about your feedback, thanks! ?

I've made a little further Progress but now I have to take a break because my filament is bound to end!

Have to wait a few days till new supplies get delivered!

But of course I'll show you what's happened in the mean time!

The break cylinders and the tank support are mounted.

The rear rims are also finished but will not be mounted before having painted the chassis! 

By the way, I'm also expecting a new printer. I'm really excited about that 'cause it's going to be more automated. Print bed leveling ist no more a manual pain in the ...! 

And it prints a bit faster than the old one!

Hope the quality ist also as much better as promised!

We'll know soon! ?

[Rockford]

Looking good Jürgen, looking forward to seeing this come together. 

[Jürgen M.]

Thanks Rockford. I´ve primered the chassis in the mean time, soon I´ll put on the top coat. The front rims are in print (for the third time!) had problems with my printer. Hope they´ll turn out ok this time.

[Jürgen M.]

Hi Folks,

the engine is in print. Had to design a new Transmission because the one I used for the Diamond Reo COE was too big.

Since the front part of the chassis is lowered the standard engine doesn't fit. I also made a new oil pan. It's flatter so it doesn't interfere with the steering rod!

I also printed the rack which holds the air filter, and the exhaust system.

Tomorrow hopefully I'll get the new printer. The new filament arrived yesterday. That's why I was able to go on with printing!

I also had to change the position of the turbo charger from the right side to the rear of the engine and therefore also the intake and exhaust manifolds. 

You'll get to see those soon. 

Stay tuned! ?

Hi everyone,

The chassis is finally painted.

As soon as I get the tires (had to order them, ran out with the Diamond Reo!) ? I can put on the wheels. 

Anyway, it's going forward bit by bit.

The engine is ready to be painted, will happen tomorrow or saturday!

This was the test if everything fits in!

Love the progress. 

[Jürgen M.]

And here's the engine:

Will be painted soon! ?

[Jürgen M.]

Hi Guys,

here's the painted chassis with engine and shaft.

Hope my new printer arrives soon. Want to geht the cab finished.
