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.

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.
