Putting the wheels together

Today Mr Ward gave us a bag of essentials for our car. In that bag was;
Axel = steel
Gears = polymer (plastic) - polycarbonate
Tube = polymer (plastic) - polycarbonate
Wheels = rubber
Nuts = metal
Buttons = metal and polymer (plastic) - polycarbonate

We had to cut the axel in half and the tube into quarters. We would then hammer the large gears onto each axel, then put the tubes on either sides of the large gear. We would then put the wheels on each but only if it had 9-10mm in between the tube and wheel. Then we had to put the button in the holes in the handle, we then had to secure a nut around it so it wouldn't fall out.
What I enjoyed most about doing this, I may have been hard but our friends were all helping each other and supporting each other.
