Union Pacific BIG BOY 4-8-8-4 1/25 Scale (Engine)
 

Hello there

I decided to sprit to new thread for easier looking.

FRONT ENGINE SECTION
-----------------------
I return back to designing and adding details to the engine. I drafted 3D model since last year. Now I am turning all parts to be a paper model. I have to add the paper thickness to each part. And design how to assemble them.
For the engine I want to sprit to 3 sections. Front Engine , Back Engine and Boiler. I start from the front engine first. This section included with Engine Truck , Front Engine. Most of parts are ready to be unrolled.

Trying Drive Wheel making
 

Hello all
I finished the test build of Main Drive Wheel. It works well. There was some gap between surface and surface by cutting and bending errors. I repaired by adding big volume of glue to those gaps. And removed the exceed volume by a cotton bud. Those gaps were completely removed.

wow... internal structuring for each wheel. I'm gonna have to build this one.
May I ask how you did the weathering on that wheel? It looks rusty and dirty.

David

The mind just boggles...very impressive.

WOW = it just keeps getting better and better!!!

I used Tamiya's wheaterning master B-set (rust) and dry brush painted to all corners.

How do you cut out all your card parts?

Do I see different weights of card?
What are some of the card weights you used for the wheel construction?

I used cardboard 1.2mm and 190 grms for skin. Cardboard I cut by hand. But 190 I cut by a sticker cutting machine.

And thus the maestro penned the opening measures of his magnum opus ...

Intermediate Drive Wheel
 

Hello there , I just finished cutting cardboard pieces of another kind of drive wheel.
The frame position is quite well fitting. I tried without glue. Parts connection is very strong.

Just posting to keep updates on this thread, there are no normal words that can discribe this :eek::eek:

My wife, my son, myself, are in awe of this train. That spans 9 to 51 years old. That covers a lot of awe and crosses gender (not to be read "crossgender", but he-she would probably be in awe also. Just trying to be politically correct). O.K. shut up now John.

You must be from another planet, kooklik!
Amazing layout, precise fabrication, simply gorgeous work!
Too darn perfect to be human!

I am starting a savings account just for this masterpiece!
Your sub was spectacular but this blows my mind!

Makes me wonder, what in the world could you possibly do next????

Your new nickname is HJ, in my book!
Halinski Junior!

Russell

Oh, it's so good to see more updates on this!

Oh my ...... I can't believe my eyes! kooklik, outstanding project!! :eek:

It was more than a year ago on an "other " forum I suggested this one:D

ohh man.... that would be GREAT!! I second that suggestion.

Thanks for answering my weathering question Kooklik. I'll try the kit.

David

That's a real monster !! I saw it in a documentary program "Top Ten Big Machine" or something like that. Very fantastic subject. :)

Have fun with trying it. I have not much experience in weathering. I would be glad if you share you trying here.

:) Cheers

Need help
 

Hello there
:confused:
Now i'm putting details to rods and links. I have no detail of the point in the picture. I don't know how they link each other. I want the detail. I would like someone who can take photo from the real Big Boy for me. Or you already have the pictures please send to
[email protected] or post picture(s) here.
Thanks for advance. :)

Here is another "next project suggestion":D
BTW, I think Willygoat lives close to one of them.

Yes , Willygoat may be the one who lives close to there. Oh what a beautiful Steam Engine. It's possible if i can find its drawings.
Cheers
----kooklik----

Here is things I've added more details. Side Rods connection was wrong until i found the mistake by Willygoat's pictures. There is no erecting drawings for rods linking.

If you still need pics, just let me know. I may be able to grab some in the next couple of days.

Your phottos help me alot.

This is going to be a Master Piece:DRick

Thank you Rick.
Now I am making another side of wheels totally 8 drive wheels will be finished soon. But now I have to stop painting. It's raining everyday here. The too high humidity here knocked out my airbrush. The 3D modeling is going well. I'm re-designing mostly all parts around the drive wheels.
Best Regards

Hello all
I redesigned the side rods and all links behide the cylinder.

Finished all front drive wheels.

Beautiful wheels kooklik. I can't wait to see someone (else) build this monster.
:D

This continues to solidify its position as most impressive design/build of the decade!

This model is just plain fun to watch come together.

More, More, More

Hello
Thanks for all words. I've not updated here for a long time. I was redesigning almost all parts. Added details to chassis , brake , suspension. All parts are ready to be unrolled.

Finished the chassis. All parts are well fitting.

There isn't an adjective fit to describe your work. Awesome, incredible, and fantastic don't even come close to describing your abilities. After seing what you did with the tender I can only imagine what is in store with the locomotive.

Wow, Kooklik! I can see another purchase from you in my future!!

Thank you Zot and Chris
The frame will be skinned soon. Before doing I will add some pattern on the skin first. There will be many parts stick on them. The cylinders are one of complex part. The pipes and joints on them are movable parts.
Best Regards
----kooklik----

That is absolutly masterful.

Thank you clevermod01

Today I have new parts to show. The drive wheel box and its centering unit. The coil spring was made of 1.2 mm copper wire. Coiled on 3.6 mm shaft.

Fanpapertastic Kooklik. The time and effort you are putting into this design is amazing. But, your building skills blow me away.
