David,
Have a safe trip, and see you when you get back.

If you're interested in shooting enamels, MCW paints has just introduced a full line. I'm going to be trying them out myself real soon. Nothing shoots nor looks like enamels in my book.

Thanks Joel, means a lot.

I use the latest posts button so that I don't really miss any posts.

I don't know much about trucks but, I research a lot for each build and I'm constantly learning more.

As to the tires, they came that way with the laser engraving and I read about the foam filler on another forum.

Anyway, I got the MM Italian Red laid down today. I'm trying to run through as much of my Testors/MM paints as possible since Rustoleum has killed the brand.

I'm on the road all next week so it will have plenty of time to cure.

David,
I'm finally catching up on the goings on here on the Truck Forum. I just don't get here very often. That's surely a major loss for me.

My overall knowledge on trucks and truck modeling is at best "0", so I usually look at a truck build from the point of view of a modeler only. And so far I've loved what I've seen here. Your engine detailing looks most realistic. Same goes for all those lines weaved in, out, and around the chassis.

And your tire detailing really has kicked them up more then a few notches. The foam does give the tire a whole new look, and the laser lettering decals look better then the real deal.

Like you, I never really have anything to drink on my bench or computer desk as it just ends up seating there either getting cold or room temp warm. I've tried playing music or having a pod cast on, but in no time flat I've tuned them out as my focus is on the build. What I keep on my monitor is detailing pics and info for quick reference, and at times, even forget about any of that.

I'll be following along for the rest of the ride for sure.

Thanks Nick.

Cheap Chinese 24 gauge solid core wire I found on Amazon. LOL Came in a two pack of black and red (that is closer to orange and might work for heater core hoses on a 60's to early 70's car)

Hi David, I'll second that - the engine turned out really well! Nice touch with tubing with the lettering on it! where did you find that super detail part?? really looks good -

cheers

Thanks Jim, it is weathered more than shows in the pictures. Flash washed it out a bit.

While still waffling on the main body color I managed to get the engine painted and weathered. The MM Bright Yellow over MSP 1500 Black looks just about right to me.




Engine is just mocked into the chassis as I still need to finish rusting the exhaust manifolds.

The rest of the parts, including the body, are in primer.

Thanks D. I've been working from home for more than 4 years, so a quick trip to the basement is easily accomplished if my phone stays quiet.

Can't wait to see how it all comes together, but I still haven't decided on a main color. Leaning towards Italian Red at this moment.

Gotta love a long lunch within reach of the workbench!

Very nice progress on the detailing David, this build is shaping up beautifully.

Had a long lunch today and spent some time in the basement doing some plumbing. The AMT supplied vinyl tubing is pretty hard to keep in the shape you want as is has no core. I used some solid core 24 gauge wire that had an overall outside diameter of .055"/1.4mm. Worked very well and kept the shape it was bent to. The other lines are .035"/.89mm solder to replicate the hard lines.

In this case, I used artistic license as the relay valves would be hidden by the fifth wheel plate and I just made up some manifolds instead to give them a place to go.

The rear service brakes are fed down one side through a tank into the manifold and then to the forward actuators. The parking brakes are the solder line feeding under the front brake air tank and onto the manifold then to the rear actuators. There is a solder feed line into the front brake tank and forward to the manifold then the wire lines to the front brake actuators. Sounds complicated, but it took less than an hour to plumb it all.






Engine in primer.

Ryan, this lacquer laughed at the Simple Green and purple cleaner as well. I hit it with everything I could and it just wouldn't go away without resorting to scraping.



Well that stinks. I had seen AMT kits work differently before, here is another example to add to the list.

Looking good. I like the backer rod trick, I kept wondering why I hadn’t returned my package after a remodel. This is why.

I have seen a film under the chrome before, I strip my chrome using Simple Green. That layer or remnants are easily removed with water and old toothbrush.

Looking good David - As I mentioned before, I have a hard time building square truck chassis - almost harder for me to do than scratch building! Yours seems to be going together as it should! I like your trick with the tires -

Cheers
Nick



I have picked up this with extra magnets, I have found it to be a helpful tool to greatly improve my building. You probably make your own but us mortals are not as gifted.

White 1500 primer coat on the backsides of the wheels and Black 1500 on the chassis, engine, suspension and various other parts laid down between this morning and evening.

Airlines and another coat of black primer after that.

I'm going to use MM Bright Yellow over the black to replicate the Cat Yellow.

Great idea with the backer rod, it really does bulk out the tyres and give them more presence!

I think I remember reading that the "goop" under the chrome plating is a lacquer based clear primer, maybe try a bit of lacquer thinner on a brush in a safe spot to see if it moves. Hopefully it hasn't filled the surface details too much!

Making good progress, it looks very neat.

Cheers, D



Thanks Damian, I'll try MLT first and then the straight LT.


Edit to add. MLT had nearly no effect on the lacquer, straight LT softened it to the point it would smear. Not going to take a further chance with it at this time.
Damian, Thank you for the suggestion though.

The tires/tyres in AMT kits used to be some of the worst to get aligned and keep aligned on the wheels, too narrow and to large of a diameter compared to the wheels.

Well, AMT fixed that issue, in this release at least. However, I still stuffed them with 3/8"/10mm backer rod which is a closed cell foam that is used to fill gaps behind caulking.

New tires with and and without the foam inside. I used a 3.5" long piece in each one. It gives a nice hefty appearance to the assemblies.

Some comparison shots with and without the foam insert.
Laser printed lettering on the tires.





One of the fuel tanks finished and mocked into place.



A few more parts to clean still and then I hope to start laying primer before the end of the weekend. Black primer on the frame, white on the wheels and gray primer on the cab.

Also, had a strange occurrence when stripping the chrome on this kit. Some of the sprue sections had an over abundance of lacquer under the chrome that would not come off and left goop in recesses, etc. 91% Iso and more oven cleaner would not remove the goop.

Thanks Jim and Gabriel, I'm pretty sure I'm now going to have to scratchbuilt the intake plumbing from the filter as the intake is now a bit further back. One modification causes the next. LOL

Hi David,

All is looking good! The tubing on the engine looks the part too.

Funny you'd mention frustration with assembling the chassis and setting the springs correctly - I always struggle with that. It shouldn't be that hard, but it clearly challenges me, and what's a real bummer is sometimes, you really can't tell if the alignment is wrong until the wheels and tires are on, and you can or can't see light below the tires! I usually see light! haha -

Yours looks right - looking forward to seeing your next update -

Cheers
Nick



Thanks Nick, It was obvious in the dryfit stage that the rear springs were off. On one side the lip that runs against the bottom of the chassis was about a millimeter away from the rail, on the other side it was about .5mm short of making it to the bottom of the rail when using the alignment holes.

What I did was measure from the back of the rear spring hanger to the back of the rail and match that on both sides after the pins were cut off. Without the axles on, that seemed to give me a correct setup.

No work on it yesterday as we went to one of my brothers' place all day.

Yard work today and then some workshop time tonight hopefully. Going to tackle the steps and straps on the fuel tanks next.

It's getting interesting here, David. Plumbing the injection pump seems to be a relatively simple and very effective detailing trick. Saved to the cloud!

Nice looking engine & frame. It's really coming along. Kind of makes me want to pull my LNT8000 back out.
