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.

Lookin' good Pal! Keep going! It's a really unique build!

That interior looks incredible! As realistic as the rest of the truck! Fantastic!

Don't worry, your frame looks very good and straight. A good start! Just take your time and you will be more than satisfied! Keep up the good work!

Thanks Guys! I hardly have space enough for my filament printer. I already sold the old one to make room and I won't sell this one! Maybe someday I'll get one but not at the time! Anyway, I need some sort of motivation to improve my skills in this one! 😉

Did the big plumbing of the exhaust and air intake, shocks and rims! I know, it's not all authentic IH but that's the nice thing about designing, you can make things fit the way you like! Just like scratch building, it's not always 100% (at least mine isn't) but it works! The result is what counts and what the builder has to be satisfied with! 😉 The rims I took out of my virtual drawer. I had designed them for my R.D. Mack! The exhaust stack will be a donor part from an old knocked down Volvo F12 Globetrotter as well the seats. The quarter fenders are carry over parts of one of my favorite builds, the IH Conco! They're staying in the family! Tank brackets are my "standard" self designed parts a bit modified to fit the short chassis. Fifth wheel is from a previously built Convoy truck I built. The K100 with the belly dump. Everything else is new and specially designed for this build! Hope you enjoy the thread! The virtual part is almost done. Then comes the hardware!

Here's a bit more progress: This is a virtual mock-up to see if everything will fit and there are no parts collisions to be expected! The chassis with fuel tanks, mud flaps, battery box, ... With cab: Now I have to isolate the parts into single print files! Of course there's still a bit to do designing parts! This is not all yet. The shift tower, some interior parts, tail lights, drive shaft, exhaust, air cleaner, ...

Did some designing on the chassis and rear axle! Again I used my finished model as a reference so it's probably not 100% authentic but who will take a look at the rear axle when the rig is on the shelf? The chassis will get a bit more details later. That's all for now!

Thanks for your efforts! Still I probably won't use all this information in my build! It's not to be rude or not to deny worship of your efforts so please don't be offended! My goal is to let the first impression show the primary attributes of this specific movie truck. Since there isn't much picture material to use as references I'll try to make it look as close as possible!

By the way, if you're wondering why I called this thread "Convoy, take 7", it's because it's my seventh Convoy truck and I wanted to make it sound a bit movie like! 😊

I did some research and found out that it's actually called a CO4070b which followed the "a" around end of 1972! The differences are mainly the head light bezzles and the engines! The b cab was set a bit higher to make room for larger engines! The cab itself as well as the chassis didn't change much. Only a few minor details like the chassis front also to adapt to larger engines! That's about all I was able to find out. Interesting but not really relevant for my build though! I'll put in the V8 I already installed in the Superliner! In my Ertl kit there's also a V8. Hope to make more progress this weekend like designing the chassis.

Thanks for the infos! Still I'll be building the "Magnavox" IH! I already have a tandem IH CO4070a. What exactly are the differences between the 4070 and the Transtar II? The head light bezzles are different but what else?

Hi, I just posted a thread in "Big rigs ..." but accidently Not in "In progress ..." but in "Under Glass"! Is there a way to transfer it or at least delete it so I can post it again in the right place? Sorry for the inconvenience! The title is "Convoy, take 7" Thanks! Jürgen

Oh my God, I posted this in Under Glass! 🙈 I'll try to delete it and put it over to "in progress"! Sorry about that! Thanks to Stichtup for transfering my thread to the right place! 👍

Hi Folks, I've been struggling about what to do next and changed my mind several times. Finally I decided to do one more Truck from the movie Convoy! This time I better not say it's the last one! 🙈 OK, enough of my personal bla bla. This is it: an IH CO4070a Handle in the movie: "Bald Eagle"! I will of course design and print all parts myself. At least of the truck. I'm not sure yet if I'll purchase a reefer kit. (It's a lot of printing!) You'll be the first to know! These are the first parts I designed: The cab with sun visor ...and the interior tub with dash: I downloaded the instruction sheet of the AMT kit to see the details of the interior parts better. Hard to see on a finished model! For the cab I used my finished IH model: Hope you enjoy the thread!

That sounds cool! Can't wait to follow the build! 😊
