For Sale sign (found at Wal-Mart, hardware stores, etc)
3/16" thick Posterboard (that stuff with Styrofoam inside and thin cardboard on both sides)
Strait edged ruler (preferably metal and containing a right angle)
Super glue or hot glue
Here are the templates for the major pieces of the project, cut from the materials indicated. If the template sizes indicated aren't matching up to that you print (which has been happening to me sometimes), you may need to mess with the sizes in a paint program. All the sizes, though, have been made to scale in Paint.net.
First, you will want to cut each of thee pieces from the materials indicated. Any right angles are made easier by using a triangle ruler. This will help prevent future mistakes and keep the tank from having a wobbly effect.
Next, gather the wheel well pieces. From the posterboard cut 2 pieces which are the same length as the plasticard piece but 3/8" shorter from top to bottom. Using either super glue or hot glue assemble the pieces as show in the image below. The posterboard pieces will allow for the wheel rims to sit nicely in the wheel well when we get to that step.
Taking a second wheel well piece, glue so that it matches the other side. Duplicate this effect with the other two wheel well pieces so that the two sides match up.
Now that you have your two wheel wells put together, gather the two posterboard pieces. Take the piece labeled as the top and cut a 45 degree angle into one of the shorter sides. The top one you will glue along the edge of the wheel rim with the angled side overhanging past the back edge. You may wish to use 2 pieces of posterboard which measure 1" by 2" to provide for structural support as I have done here.
Glue the other wheel rim in place so that it is flush with the first side you glued. Next glue the bottom in place so that it has an even distance from the front and back of the wheel rim (this should be almost non-existent). Taking the front bottom piece glue into place so the long edge is even with the posterboards bottom edge. Match the front angled piece so it connects the bottom front with the top (it's ok if there is a little overhang- simply trim this using your hobby knife). Do the same at the back of the vehicle frame.
Next add the wheel well detail pieces to the sides of the vehicle. Measure carefully the width of the wheel rims with the plasticard attached and cut strips of plasticard which will run the length of the vehicle's wheel frames. Starting at the front angled part of the wheel well, glue the plasticard in place, following all the way to the back of the vehicle. At each of the bends, gently score the plasticard with your hobby knife to allow the plastic to bend without breaking apart. At the very back of the vehicle cut the piece so that it only overhangs about halfway (1/4") down to leave room for the wheel track. Do the same on the other side.
Using the left over from those plasticard strips (you saved that, right?) add pieces to the front and back just like it appears in the image above. Now sand all of the edges so that they appear rounded.
Well, this is going to conclude the first tutorial part of this vehicle. Next week I will go over how to make the wheels, tank treads, front visor, side exhaust ports, rivets, and the top and side doors and hatches. Till then, happy scratch building!
