Default Unimog 6x6 (full custom)

Hi,

I'm doing this Unimog for quite a while now with several iterations as my skills improve. So long that it suffered the "Great PhotoBucket Crisis" and then, the TinyPic going down. For that reason, I've lost my initial photos but,basically, a Unimog was built from scratch



ch:








That mirror has a recess for a piece of selfie mirror:
















It had a custom 6x6 chassis, running scx10 axles and front motor

After several months of successful running, decided that it should have portals and began to work on that.Initially,i was thinking of machining them but it sounded better in my head. We don't have a CNC machine at work so even with lot of work these parts would look rather crude. I thought in 3d printing which allow for the "casted part" look I was searching forThis it's the first prototype


This was the improved version mounted on a scx10 axle:


The spheres on the housing ends meet 2 purposes:
-look more like the 1:1
-the portal boxes widen the axle 18mm so I've narrowed 20mm

First prototype of the rear ones:


mounted on SSD housings look awesome:







Better things to come, I promise. Keep tuned!

Thanks guys!

I had the first headlights for the 'mog 3d printed but they weren't 100% what I wanted, so armed with fresh noob solidworks skills I tried my best to replicate the real ones:

They turned out alright




Some aluminium foil to spread the light



I think they look better..





They're mounted on a new bumper that's exactly the same as the old one. Had to make another because I'd took it to the shop, painted it and someone lost it somehow. Probably thrown into the trash

at least you know solid works I use tinkercad
don't get me wrong I've designed some bonkers things in it, but it has its limits namely things like importing stl file sizes.
too bad the transparent filament wasn't clearer.

Solidworks was a very steep learning curve, in my opinion coming from AutoCAD but is powerful when mastered(I'm far from it ). I cannot use other software right now , tried Fusion but can't handle it.

The "clear" lenses were a bit of a let down but I've solved it with another solution



Portal axles are great for clearance but the 15mm extra clearance , also raised everything 15mm,the truck looked like a monster truck and it needed a new chassis. Kept delaying it but one day,after work, had one of those "now or never" moments,blueprints in hand and 10m later:












Looked out of scale, made of 16mm tubing but the 1:1 blueprints showed 17cm frame rails so it will work out









Got a Helios 2sp a while ago on a deal and even if it's a small size 2sp gearbox, that size don't allow being on many builds. This 'mog has plenty of space for one.I don't really need 2sp but I dig the scale looks of it





In my current chassis, used a Scx10 skidplate but the new one has to be custom to accommodate the Helios.























At ride height













Sorted out the links mounts. Not pretty but seemed the best idea

The axles weren't really finished. There was some rubbing inside of the portals and against the rim. The rims only needed a bit of machining. Pretty tight,eh? :



Now I have 2 rear axles looking like this, no frictions. Pretty smooth, actually



The front parts are a different history. The steering was kind of limited because the dogbone cup was binding on the inside of these axle ends.

On the left, stock. On the right, what I had to dremel to solve the problem:


And how it looks without the axle housing:



The rear shock mounts now



Some Unimogs are like this:

Views:	46

my take on them:






Had to invert the location of the shock/spring because of the sxc10 axle. Uses a long scx10 spring and these nice 60mm shocks:

The chassis progressed. New crossmember, battery craddle and the rear shock mounts are in place



All the links(i know, Unimogs don't have links...)



Forgive me the lack of torquetubes with photos of ground clearance

I wanted to make the truck standing on it's own so the work order was: front axle truss, panhard and upper link and spring/shock mounts

The truss

Started with the axle springs mounts, similar to the 3d printed i have in the back but in steel to be welded









Added a 5mm square steel rod,tight to the housing





To finish, the panhard mount next to the knuckle and the angled upper link mount





The idea behind the truss was making it low profile so it wouldn't hit the frame rails but in the same time, looked from factory. The angled link mount allows to use straight rods and has a thread to avoid the "nut and bolt"


The spring mounts:







In place:







Next, secure the bumper

The bed:

It's first iteration was made mainly in balsa wood, seemed like a good idea at the time:



Painted, looks good enough but can't handle the trails

So,had to do another and using the opportunity to make it wider because that was another mistake I've made. So, this one is 30mm wider



First, the bottom:



And then, one side:



Back:


With primer:





Honestly, hadn't a fixed idea on what to do besides a floorboard look

Scribed the all the lines and started with the "nails":





After all the nails, some black spray, a bit of sanding to do a kind of black wash,apply a heavy duty metal brush to do a wooden texture and finally the brown:





more zoom!



Honestly, i was surprised with the result as the paint could fill the texture of the metal brush but turned out nice. A mate clear coat in the end will take the shine away



Has hinges, only need to replace the lower screws for shorter ones:








Very satisfied with the bed width, the bedsides drop perfectly

About the bedsides:


It's time for ziptie all the electronic and try some rocks:

more on the bed:

The bedsides open,good...but they have to stay closed most of the time so i've came with an idea that it's not hard to execute and don't look out of place

First, machined these 3mm pieces with a 1.5mm hole for the pin (dowel?):


then, made the part that bolts on the bedside:









The black bolts should be countersunk but the tool failed on me so had to use these ones. The chain will be replaced if I find a smaller one



All the latches done, rear tailgate and it's steps:











Bishop approves:

Small detail that was bothering me for some time:







Long time ago,I've ordered a Axial parts tree only for the door handles. Not lazyness, only lack of skills. But the tree only had 2 so they went to the doors. Now, I can do stuff out of Styrene

Also carved the holes, they're not painted because I'm doing underside detail on the hood


The guys who print my stuff offered to model and print an Unimog engine so I took the chance.

straight from the printer:

It could be more detailed but i wanted to add parts later. The sizing isn't true scale but there's space constraints on the place, there's the 540 and the servo over there

First, exhaust manifold, turbo and an alternator


Then, the intake manifold


The engine driven air compressor for the onboard air tank


Injector lines


Turbo Downpipe


In place
[IMG][/IMG]

It will not be a perfect replica but it's enough to cover the motor and servo. Needs more stuff like air filter, pulley belts, some pipes and paint

While the fake engine and the rest of the parts were getting done outside the car, one more important thing has to be done: make it run properly!

The cab has new mounting points(4 screws inside the inner fenders) and attached the bed on the chassis.







The bed tips to change batteries, that sit above the middle axle,between the frame rails


And off to the trail!!

A little more work on the engine





Mounted it and the air filter. Needs a couple more parts to fill this bay










While the bay is slowly being completed, did something else:







This printed wheel is a copy of the Gmade SR02 already in the truck but thin as possible to fit under the bed as the real one







Just needs a mount welded on the chassis

Working on the rear fenders(mudguards?? )

















Bent in 0.9mm aluminum sheet. Only bent one to approve the design. What do you guys think?



The real ones can be like these:

Thanks! keep tuned because this is not one of those projects that are forgotten at middle way

Already had a fuel tank, done years ago and like I feel my skills improved, so re-did it













Not in the final position (hot glued in place).

More 2 parts to fill the engine bay:

This coolant reservoir:





And upgraded my old radiator:









After adding everything to the bay, will hide the blinker's wires....

My current bed is fine but i've scrapped the idea of the canvas because there's no way I can put functional hooks on the thin aluminum that's on the bedsides so I'll make a brand new bed for this purpose

The idea is to look like this:

This time, I'll print the bedsides because of my current personal situation, and doing the floor and struture as before,with wood and PVC sheet

2 prints, 1 side:


How the corners would look like


Giving some wooden texture to the PVC


Small nails to mimic round head bolts securing the planks


Black for panel gaps


Painted in a colour that should be brown but it's more like dark olive drab so it will stay




Next is prepping the sides to paint and attach

So, I've scratchbuilt a fuel tank earlier. I think it looked good enough but seemed a bit small. So I've copied the shape, enlarged it a bit and printed. That was some time ago but today picked it again to apply some paint and did something else

see the mounts below the tank?

Anyone knows why the pics are small?



Well, things are going slow...was anxious to get the metal stuff done to pass the bed to the lady who will do the tarp.







At first, I will only make the front and rear arch like the real ones but all my reference photos were from 4x4s. This long bed would need one more,atleast

The archs are 4mm stainless steel and the rest 3mm. The feet are steel, brazed to the archs.Was planning to braze everything but I'm quicker with the TIG.
