2 toilet-paper tubes
Cereal box or some cardboard
1 or 2 straws
Make your bulldozer blade!
I started out by making my bulldozer blade. Simply cut one of your TP tubes in half the long way. I ended up cutting it down a little more so that it was about 1/3. Looks like a bulldozer blade to me! You can even cut the edges at an angle a little bit to make it even more cool.
Make your bulldozer arms!
Next you can make the arms that will hold your bulldozer blade. Stand your blade up on to a piece of cardboard and trace out its circular profile. Then draw out your arm design. Make it about three to four inches long. Cut it out and trace it onto another piece of cardboard. Then cut that one out. This way both of your arms will be the same. Next make a hole on each arm so that they can slide freely onto your axle straw.
Add the axle holes!
Now make four holes onto your other TP tube. You will want to make them as level to each other and as evenly spaced as possible. I spent a few moments with a ruler and marked my locations out first. Then using a hole punch I carefully made my holes. These holes need to be slightly bigger than your straws.
Add your axles!
For my axles I cut out pieces of two straws so that they stuck out about an inch on each side. I inserted them and then made a few adjustments to my holes. Basically, I made the holes a little bigger so that my straws would turn freely.
Make your wheels!
Take an old box or piece of cardboard and draw four circles (I made my wheels about three inches in diameter). Then carefully cut out all four wheels. Find the center of each wheel and make a small hole for your straw axle to slide through. Try not to make the holes too big, or the wheels might wobble.
Start to assemble your dozer!
Start to assemble your bulldozer by installing the back axle straw then slide your rear wheels onto it. You may want to add a little tape to hold your wheels on it they are loose. Then place your front axle straw in and slide both of your bulldozer arm onto it, one on each side.
Add your wheels!
Now install your front wheels. At this point I rolled my dozer around a little and then made a few last-minute adjustments. Before you tape it up permanently make sure your wheels can turn and that the blade arms are loose. If not, make the necessary adjustments.
Attach your blade!
All that's left is to attach your front bulldozer blade to both of the arms. Find a position that you like and tape it on. VOILÀ - a TP Bulldozer! You can start rolling it around or dress it up. The sky's the limit!
