1. Pencils, brown wrapping paper and a big eraser.

2. Router (if you don’t know anyone with one, rent one for the weekend)

3. 1/8" straight router bit (preferably "guaranteed against breakage")

4. Aluminum security tape Radio Shack (49-502) or copper tape for stained glass.

5. 2" x 4" lumber for table legs/support

6. 5/8" or 3/4" particle board for track surface (known by various names in various markets).
    MDF (medium density fiber board) works well too. Note, MDF is very smooth and a couple of people have commented that after it's painted it's TOO slippery for the cars to grip, therefore carefull testing of the painted surface should be done before commiting yourself to the MDF/paint combination.

7. Various nails/screws, hammer, screwdriver .

8. Household wire (lamp cord).

9. Soldering iron, solder, flux

10. Plug jacks

11. Oil based gloss paint (gray, green etc.) and paint brush. See point 6.

12. Plastic Wood, Putty Knife, Sandpaper

13. Drill, Jig Saw

14. Wallpaper Seam Roller (optional)

15. Drywall joint compound.

16. Safety goggles  ('cause we've got no insurance if you get hurt).
 

Then you need to make or buy two simple tools.

First, a large "Compass" that will hold a pencil at one end and have a series of holes at the other, measured off to represent the radii of the corners. A piece of thin plywood measuring 2" x 18" should do any corner you can come up with.

 
 

Second, (if your router doesn't come with this attachment) you need to make a "Circle Making Jig" which is essentially just another compass that uses a router rather than a pencil. Most routers have several holes in the base plate that will allow you to attach a "Circle Making Jig " or as Art refers to it, "a stick with a nail in it". A wider piece of plywood (equal to the width of the base plate of the router) should do the trick.
