that is super cool..what length is the trailer ??

[Aaron Corey]

The photo of the actual 1:1 trailer in my first post shows the 32 foot version; however, I'm building the 29 foot version (approximately 14 inches in 1:25 scale). So mine will have a much smaller gap between the hopper and the wheels compared to that photo. Midland also sells 40 and 42 foot version with tri-axle setups.

Hi Aaron,
Very nice modeling, your trailer is looking great I do have a question that maybe you or another member maybe able to help me with, Does anyone make a scale ruler for 1/25th scale? What I'm getting at, currently there are scale rulers that model railroader use for 1:160, 1:87, 1:64 and 1:48 scales, where all the measurements on the rulers are in foot and inches. Does this type of ruler exists for 1/25?

Thanks in Advance,
Rich S.

[Aaron Corey]

I'll need to pick up one of those scale rulers someday. Up until now I've just been using a calculator, and once in awhile I'll mess up one of my measurements.

Here's my latest progress; the hopper is attached to the main body:

Aaron,

An excellent topic and build, its great to see how you have gone about the works so far.

[Aaron Corey]

Here's my lastest update

The front and rear "bumpers":



The hopper doors:





Next, I'll be taking the suspension from the AMT Fruehauf flatbed trailer and adapting it for this project...

Very nice scratchbuilding!

[Aaron Corey]

Thanks guys, I'm really having fun with this project.

Now I understand why the real trailers are built the way they are: Even though I'm mainly using 0.020" styrene (which is pretty flexible on its own), the fully assembled trailer body is surprisingly strong and stiff.

Whoa, some cool work going on here. I don't usually check out the semi truck threads, but I'll be checking back on this one.

wow nice build, found a future project idea

[Aaron Corey]

I've assembled the suspension, and attached the frame rails to the bottom of the trailer. The suspension came from the AMT Fruehauf flatbed. The frame rails are 4 inch sections cut from the frame rails in the AMT kit.

[scale trucker]

not to pick but the boggie is backwards

[Aaron Corey]

Good catch with the backwards suspension, it was actually a deliberate decision on my part. When I was mocking up the rear suspension I discovered that I had to put the bogie on backwards in order to prevent the rear tires from interfering with the mudflaps.

Now that I look at the photo, I realize that could solve the issue by trimming the front of the suspension (the part that grips the frame rails) to allow it to sit further forward on the frame rails...

Great work ! Cant wait for more pics ... rich try micro mark they have everything to do with scale building

[Truck parts]

That's one outstanding build. Looking forward to seeing it done.

[Aaron Corey]

Thanks for the great comments guys

I've fixed the suspension. Here's a mockup to see how everthing fits together:



Now, I just need to add a few more details (push block, air cylinders for the hopper doors, mudflaps etc.) and then it'll be time to paint.

[Aaron Corey]

I've also created the artwork for my decals. It's based on the actual paint scheme used by the manufacturer.

[Aaron Corey]

Now I've added the push block and mudflap brackets:



...and the air cylinders for the hopper doors:



Now I just need to paint and decal, and this thing will be done.

I like this too
I may convert it to 1/32 scale.

I have a set of aluminum scale rulers from Murphey.
Murphey's Rule 3 has 1/25 & 1/43 scale

Murphey's original has 1/72 & 1/48
Rule 2 has 1/32 & 1/35. (have to find where I hid that one!!)

I ordered these several years ago from an ad in a model 'Enthusiast' magazine,
so I am not sure if they are still made.
