The shifter fits perfectly and the tilting of the cab will work fine! It's still a bit shaky though cause the tilting axle I used here is too thin. It's just for try outs. VID_20250604_160121~3.mp4 I also printed the grille and side trim. Looks OK! Maybe It could use a bit of improvement though!

The steering parts: Put together and mounted: And it works too: VID_20250604_110414~2.mp4 This is about the smallest you can print in a filament printer, especially when you need functioning parts!

I took off the tub and worked on the chassis and engine. Still have to work out the exhaust system. Toughy! Fuel tanks are printed and painted. As soon as they're dry I'll assemble them and add the cable ties I always use as straps. Then I can mount them. The cable ties are my standard as straps. I've designed a few different types of brackets all made to tuck away the heads. And you can paint them any color you like! Even chrome! I've also made a steering gear in a similar way as in the Ertl kit! More to come soon!

A mock-up to see if the cab will fit over the engine without collisions: Up to now everything fits perfectly! Quarter fenders are just mocked up, they still need a bit of adjustment. The rear panel, fifth wheel, battery box and air cleaner are permanently in place!

Wheels are mounted! Hubs are next. Then the air cleaner and exhaust system!

I decided to not paint the chassis flat black but lo leave it as it is! Here's a little mock-up: The exhaust (heat shield) is from a Volvo F12 Globetrotter. The end pipe is printed. Wheels are painted. I'll mount them later this evening probably! The space between cab floor and engine is very thin so I hope to get the cab in a position where it doesn't touch the engine and still isn't to high. The great challenge will be to fit in the shift tower.

Thanks Scott! I'm aware of the differences but noone will see it later since the truck will be up on a shelf later where you can only See the outside. I used my 4070a kit as a reference so it won't be totally authentic. In this case it doesn't matter though. In the movie the interior of that truck is not shown so I will also have freedom of art concerning the colors!

The engine is painted and completed. The radiator is almost finished and will be mounted after having painted the chassis.

The interior tub is printed. I used the illustrations in the instruction sheet of the AMT kit as a reference. The three brackets I designed onto it are just mounting aids for the sleeper wall! The dash is printed too. I know, it's the 4070a dash but actually I don't really care!

The engine fits in perfectly! Of course it's not finished yet. I just assembled enough to try out if the virtual mock-up was correct.

Thanks guys! I'll try to find the middle between detail and pragmatic building. Once it's on the shelf most details won't be visible so why bother. The details on parts like the rear panel are easy to design. Things like that don't take much time!

Fuel tank brackets are mounted: Rear panel with mud flaps:

Rims are printed. I'm using Italeri tires, got lots in my box! Of course the rims need painting (white). The chassis will be painted flat black. Before that I'll test the fit of the V8. If everything fits I'll mount a few more parts like the shift tower and tank brackets. Then it's off to the paint shop!

That is absolutely..... I don't know a word to describe it! Fascinating! Amazing! Beautiful! ...

Not really! When the parts are very small and delicate they have to be taken off really carefully so they don't break but most parts are no problem. Some already fall off while I take the raft off the bed! You just have to do a lot of after work.

Brake drums are mounted. These are the first engine parts:

Brake drums are finished and wil be mounted shortly! Front axle is mounted and steering works!

The Revell chrome spray takes lots of time to cure till you can touch it. Last time I let the parts cure for 10 days which is what I recommend! By the way, putting a clear coat on it is possible but not too early. I put one on 3 days after applying the chrome and it caused a dullness of the chrome. I then tried the same with a water soluble clear coat and got the same result. Best is to leave the parts alone at least a week and then still be very careful handling them. By the way, beautiful old Mack! 👍

Attached the front and rear shocks and a stabilizer: Also assembling the steering: ... using a 1mm brass rod, two 2mm brass rod pieces and some box parts (white). Brake drums are next (being printed). Then I'll begin printing the V8.

I think there are resins that are not so brittle but mostly that effects other attributes. I'm no resin specialist though!

The resin parts are much more brittle than the filament parts. They're not as heat resistant as the resin though! 😊

Rear axle is in place! A few other parts waiting in line: Diamond plate with pogo stick, front axle (steering parts being printed at the time), front engine rest, bumper support.

More parts fell out of the printer yesterday: I also started to assemble the chassis. Front springs attached: Rear springs too: Rear axle is next. Front axle will be pre-assembled with steering components first.

I was actually thinking about that. More will not have room on the Convoy shelf. I can lengthen the shelf one more time but not much. Just enough for the current build and something smaller!

The first parts in hardware: Fresh and warm out of the printer! Now that I'm almost finished designing I can begin printing parts one by one.
