Welcome to Faux Fossil Building. I chose the Tyrannosaurus Rex because of my own Childhood Dreams of Owning a fossil of my very own. I will show you how to build a T-REX using recycled paper, recycled cardboard and a home made mold.
Step 1: Things you will need
What you will need.
1. Hot Foam Cutter $20.00 USD(optional) of a Steak knife (free).
2. Foam Insulation $2.50 USD
3. Paper (recycled)
4. Cardboard (recycled)
5. Plaster $13.00 USD
9. White Glue $2.00
10. paint brush
Step 2: A good picture
I found a picture of a T-rex on the Internet. I traced the image using Illustrator or you can free hand if you feel comfortable. Just make a Pattern that suites you.
Step 3: Tracing Patterns
I blew the Image up using a graph. I made the T-rex the size that I wanted. Use Signboard or Cardboard when making the graph for your resize. Signboard helps to keep your knife or foam cutter steady while tracing the outlines.
I then used an exacto knife to cut out the T-rex pattern. I Glued the cut out Pattern to the Foam using white Glue only, spray glue will melt the Foam. I found this out the hard way and had to make a new foam T-REX.
Step 4: Cutting Foam
Cut out the Foam using either a Hot Foam Cutter of a Steak knife. I found out both work just as well and a Steak knife is free.
Step 5: Make a Mold
Make a Mold of your Foam T-Rex Using Plaster of Paris. Make sure you glue (white Glue) down Foam original to Wax Paper. This will allow Plaster to release from the surface that you place it on and by gluing it down you will not have any under cuts under the plaster.
Spread Plaster evenly over your original at least two inches thick. Spread plaster at least three inches past the boarder of your original.
Let plaster shell dry for 24 hrs and then demold.
