There is really no definite right or wrong in building a beer can model. It actually boils down to your imagination and how great a challenge you want to accept. These slides will show you some areas that really stumped me for a while. For the rest, you are on your own.
Step 2: Things I Use...
1. 16 ounce beer cans (drink the beer first).
2. Various adhesives, but the MOST important is JB-Weld. You can do the whole project with JB-Weld if are not concerned about time. Liquid Nails will give you a faster set, but doesn't sand very well.
3. Some cutting instruments.
4. A 9 volt battery. If you break it apart you end up with six 1.5 volt AAA batteries.
5. A Sharpie pen makes a good container for the batteries. Just cut it up (make measurements first).
6. If you are going to power it, get a small switch (the style is your own choice).
7. DC motors. If you are going to make a powered model you need to start with the motor. The scale of your entire model depends on the size of your motor.
8. A great source for switches and motors is: http://www.goldmine-elec.com/
9. You will also need at some time some wire. (24 stranded is good)
10. Some shrink wrap.
