He loved playing with the T-Rex so much that I decided I would build him some friends to play with. He requested a stegosaurus, triceratops (my personal favorite dinosaur) and a pterodactyl (which I haven't fully figured out how to do yet). I built the stegosaurus first to see if I could do it and then built the triceratops next and that is what this instructable covers.
Step 1: Materials Needed
1/2 inch plywood (size will depend on how big you make your dinos)
Optional for accessorizing:
Small Hinge if you want a tail to swing
Large Nail if you want the mouth to open and close (I actually used the scrap rod from a rivet)
Scroll Saw or fine blade Coping Saw for low tech
Bench Belt Sander or sand paper for really low tech
Step 2: Designing your dinos
Once I was happy with the basic looks, I transferred them to the plywood. The second pic shows what I hoped the completed dino would look like.
I then broke down the components around the body. You will need four legs (two front and two back)...assuming your doing a quadruped. The head was made of three pieces sandwiched together...the two outer pieces were identical with each having the nose horn, main horn and frill. The inner piece had only the nose horn and frill so this would give the look of three separate horns.
The line going through the head to the bottom jaw is the part of the body that the head will attach to.
Step 3: Cutting and Sanding
Step 4: AssemblyLe
Glue the inner head piece to the outers, making sure that the nose horn and frill on all three are lined up. Nail the three pieces together. A well placed nail will do great as eyes for your dino. I did a nail on each side of the head in roughly the same spots. You may need to do additional sanding of the head after putting it together to make sure that things are smooth and uniform.
I attached the head to the body with a scrap rod from a rivet but a large nail would work perfectly also. Just drive it all the way through both sides of the head and body. The amount of room you have to work with the "cheeks" of the dino and the body will determine how far you can get the mouth to open.
Step 5: Completed Triceratops and friends
I hope you enjoyed this instructable and as soon as I figure out how I'm going to do the Pterodactyl...I'll post that one
