If you take piano wire, tire one end securely to a fixed point, then pull a 5 or 8 foot piece really tight, till it "gives', you will have hardened that piece. By the wrapping in around a mandrel of the diameter you need for a spring, you will have a hardened spring for your assembly. This is how wire is hardened. Make sure you wrap the end you star with a couple of times at the beginning, and at the end, so that if will have a flat area to sit on, as opposed to just the end of the wire.

To Enrico63:

In the actual final state of the model, suspensions are only looking nice but are glued and not working.
However I've been playing with the idea of including a spring inside the cylinder.
As correctly pointed out by Calinous, springs from usual ball pen are to strong.
One of the best spring was from a drawing pencil (picture attached).
Some elongation of the spring will also result in softer springs.
Nosports is the designer of the model and he confirms the possibility of making working suspension.
In the same time the biggest challenge seems to be the low weight of paper models.
The total weight of the rear axles carrier is in fact approx. 46 grams and at least 2/3 of the weight is represented by the wheels.
I have been also looking into possible solution with rubber bands, flexible rods and torsion bars.
Considering also that the wheels are not rotating but fast glued, working suspension become even less attractive.
I like Zathros idea of making springs and for sure I will take a note of it.
However this is only my second big card model and I'm learning the trade.
With regret for now I have to drop the temptation of making big changes to such nice model.

Now it's time to report some more progress.

Follow few pictures about the construction of the main drop deck.

1. Central sections of the drop deck not yet glued.
2. The 3 central deck sections now glued.
3. 2 end sections of the drop deck.
4. 6 lateral sections to the drop deck.

Progress updating.

1. The main drop deck ready to be assembled.
2. All parts of the deck glued together.

Happy Easter to all of you

It's time for some recent progress reporting.

1. The drop deck is now connected with the rear wheel carrier.
2. The drop deck is assembled for transport of big wheeled vehicles.
3. Wheel recess of the drop deck can be removed.
4. Drop deck is now configured for transport of tracked vehicles or large load.
5. The loading ramps in front are too short ?!?!? ......... I've to find a better solution.

Its configured for large wheeled vehicles, because the wheel-sinks are up.
They could be moved farther out for wider wheelbases.

The loading-ramps are just right, because in normal the drop-deck lay on the bottom, while loading, so there the ramps just needed to this long to get atop.

Yeah like nosports said, the term "drop deck" refers to the fact that the deck drops to the ground for loading.

It's looking really good, can't wait to see more.

To Nosports:

I like the design of the wheel recesses. Very easy to made and at the same time very flexible.
I'm building now the side extensions and the beauty of your design can be even more appreciated.

To Nosports & Jaffro:

Thanks for your comments & explanation.
I have made some adjustments and now I can have 2 levels for the drop deck.
A dropped down level for easy loading and an higher level with sufficient travel clearance.,
