KoolWheelz Tutorial Build - Lunar Rover Racer



Lunar Rover Racer

Printed model sheet...65lb plain white cardstock.
Its worth it to spend a little bit more, and buy a good brand, good quality, cardstock.
It prints better, it scores, it folds and shapes better.
Lower quality cardstocks are rougher...more "raggy"...they tend to bleed a little more
resulting in blander colours and less sharp detail.

The Rover is not a difficult model, but its got a lot of parts...and most of those parts are very small.
That makes it a more "advanced" model...
and a model better suited to someone who has some experience with bending and shaping small parts.
If you don't have that experience already...then this will be a fun challenge for you.

I recommend some good magnifying glasses for this one!

As always, I recommend a scalpel style Hobby/Craft Knife with fresh blades at hand
and a metal straight edge (rule) for making precise cuts.

A small pair of fine point scissors also comes in handy.
As do Tweezers, Clamping Tweezers, a Scoring Tool and dowels of various sizes.
Use a good quality papercraft glue.

For those of you that cheat, and enlarge you models,
the Rover model sheet doesn't offer a lot of extra room....sorry LOL
You might be able to enlarge by 5% or so...which is still a considerable upscale...but thats it.

First job is to score everything that has to be folded.
There is a lot of scoring to do...and its not all marked.

Its a good idea to make yourself a good scoring tool that can score a precise fine line.
If your score lines are too wide, you are going to have a problem on this build.

Not sure why I didn't mark all the score lines on this model sheet
...maybe I thought some folds were obvious?
And, maybe I was trying not to clutter the page? (because of all the small parts, and lack of rooom?)


So, heres a diagram that should help you out.
I know its not the clearest photo, but I think you can make it all out.
Don't worry, I'll post more photos showing score lines.



...
Once you have your model sheet all scored...lets focus on the main Floor Pan of the Rover.
This is the part we will build first.

As I promised, here(below) is a closer detail of all the fold/score lines (marked in yellow)



...
Yes, all those folding sections are not all the same widths.
So, try to be precise ...score and fold exactly on the lines.

Make sure not to score horizontally across the floor pan (indicated by the red lines).
If you did so, it will weaken the floor too much and your Rover will collapse in the middle.
I recommend you reprint this part and try again, if you scored across it.


Try to understand the chassis part.
You are looking at the underside of the Floor.
Those larger solid gray rectangles in the center area are the underside of the Floor.
We are going to fold the striped side sections over and they will be the top of the Floor.



...
Now...Cut the chassis part out using a sharp kife and metal straight edge.
Its important to cut everything straight, precise and square.

You also need to cut into the floor pan to separate the (front and rear) narrowed sections of the floor.
I've marked these cuts in blue on the next photo.
You can make these cuts before or after you have cut out the entire part.



...
There is an Assembly Diagram available for this model.
You can find it in the KoolWheelz section at www.papermodelforum.com

But I'll also use some of the diagrams here to help illustrate the assembly.

In the next few posts, I will show you how to fold and assemble the chassis.
In the next picture, this is what we are going to create by folding the chassis/floor pan into shape.

Computer problems the last few days, but I'm heading downstairs now to print out, and I should have a good building session tomorrow

Be safe. Are you in a mandatory evacuation zone?

Judging from the Paper Modelers Map he's smack-dab in the middle of it. Hope he's already left and gone inland.

Any excuse to get out of work is a good excuse. I am in a mandatory evacuation zone but I have no where to go so we are just going to hunker down and ride it out. We are as well prepared as one can be. The hardest part will be building the Rover by candle light.

Yeah, although the dripping candle wax should do an excellent job of sealing the Rover sheets before assembly. All the best in riding it out my friend. Done it once, a Cat II - Hawaii, Army, assigned there, literally no place to go. No desire to do that again. Hang tight.
