•   Tape measure 

• AP dragsters to race

•   Masking tape (optional) 

• Glue (optional)

Assembling the Spring Tensioner

1)  Cut two pieces of string eight to 10 inches long. Tie one 

string firmly to one end of the spring. Tie the other end of 

the string firmly to the paperclip as shown (a dab of glue 

can help hold the knots more securely). Slightly bend out 

the end of the paper clip (Figure 1).

2)  Repeat Step 1 on the other side of the spring.

3)  Place the spring in the middle of 

the double posts on the finish 

plate. Thread one paper clip 

through a double post on one side 

(Figure 2). Do the same on the 

other side with the other paper 

clip. 

The finish plate is ready to be used.

Setting up the Track

1)  Find a level surface. Smooth tile, 

linoleum, or a gym floor are ideal 

for the track – the dragsters will 

not run as well on carpet.

2)  Place the AP Dragster Launcher where you want the start of the race to be. The brass tubes should be 

pointing down the race track. Measure the length of track you want – it should be between 20 and 40 

feet long (40 is preferred; the shorter the distance, the more you will need to reduce the suggested air 

pressure). You can mark the track finish line with masking tape.

3)  At the finish line, place the finish plate with the post side closer to the track (Figure 3 on the next page).
