Let's Build a 3D Card Model - Step 2 -- Add Cereal Box Backing

If you downloaded and built the house in Step 1, you will need to print another set to complete Step 2 .

A.   To add strength and thickness to the model I am going to mount the downloaded sheets to heavier card stock, a cereal box.  I found a box large enough to mount the letter size, 8.5"x11", sheets.

When you card model you save boxes like this.  If you have kids you already have a ready supply.


B.   Cut open the box along the sides to obtain something like this.

Two long cuts and two short cuts provide the basic material.  Save the small, leftover parts for details to come.


C.  Cut out the front and back panels, trimming the edges to ensure a flat surface.

Here are the panels needed to mount the printed sheets.  This slick, outside surface is sealed enough for Yuma, but you may want to seal both sides with spray primer.

 
D.  Here in Yuma, Arizona we have mostly low humidity so I use the cereal box as is, leaving the printed outside surface on the inside of the model and gluing the printed sheet to the bare inside surface.  If you want to protect your model from warping with damp / dry conditions you may wish to seal both surfaces with a spray primer.
These card panels are now ready for the spray adhesive.


 E.  Use a spray adhesive to give the bare surface of the card a light even coat, locate the sheet and smooth out using a stiff ruler.  I just happen to use a tile trowel that I have around.  Leave over night under weights to ensure the panels dry flat.

WARNING: Spray paints and adhesives should be used outdoors, away from flames and with a backdrop to collect the over-spray and protect other surfaces.

All for tonight.  My panels are drying under weight and I will edit this step 2 over the weekend.  Then we start with scribing the fold lines, cutting out the details and folding the corners.

Let's Build a 3D Card Model - Step 1 -- Free Internet Download

Card modeling is an old craft with a new life.  Old timers like me will, if able, remember cereal boxes with the back printed with some toy or building.  We would cutout the item, fold on the lines noted, push the tabs into the related slots, resulting with a free toy.  With WWII over "real" toys came back on the market and card modeling in the USA fell from favor.  Europe must have spent a few more years with material shortages and card modeling held on with a newer generation.
Now, with the internet, card modeling has surged back with both free and commercial sites offering thousands of models of every imaginable type.  For this little build clinic I have chosen a free American model of a log cabin once belonging to Thomas Lincoln, President Lincoln's father.  This is one of the Build Your Own Lincoln Sites, available at 
 www.lookingforlincoln.com

The completed model is shown with the two pages downloaded from the internet and printed on 110# card stock with a color printer.  The models in this series are 1:87,  HO scale.
I have wanted to try adding depth to a printed model by recessing the doors and windows and applying the shingles row by row, creating a 3D model.  This may require printing a second and possibly a third copy to have enough extra parts to complete the modification.

But for now, go to the site noted above, and even if you have never built a card model, download, print and build the model using the instructions included.  Don't worry about making a mistake, just print another sheet if needed.

TIPS:  You can use scissors or craft knives to cut out the several parts of the model.  When using a knife make several light strokes instead of one heavy stroke.  Paper dulls knife blades quickly so keep a supply handy.  Most modelers use the #11 blade that fits a small handle.  I use a letter opener to score the fold lines making several moderate passes.  Practice will help you develop the skills and improve your results.

WARNING:  Knives and other tools used in card modeling can cause injuries if not used correctly.  Children should proceed only under adult supervision.

Check back often for updates of the 3D modifications and hints, tips and additional sources for help and information on card modeling.

See you soon!
