how to make a potato launcher

this writing is for your reading pleasure only. its suggested that you do not try to make a potato launcher

the first 2 pictures are of the stuff you will need.

( supply list )

A = 16 inches of 3 inch pvc pipe
B = 2 feet of 1 1/2 inch pvc pipe ( we suggest 2 feet minimum )
C = 3 inch to 1 1/2 inch reducer
D = 3 inch to 3 inch fitting
E = 3 inch to 3 inch threaded fitting
F = 3 inch threaded end cap
G = pvc primer & pvc cement
H = 6 inch bolt 1/2 inch diameter with 2 nuts
I = 2 3/4 inch bolt 1/4 inch diameter with 1 nut
J = grill ignition switch
K = silicone. white or clear, you choose!

NOTE: make sure to use pvc primer before you cement the pvc together.

STEP 1: 

(-)  prime & cement part E to either side of part A.
(-)  screw part F into part E. 
(-)  do NOT cement part F & part E together.

STEP 2:

(-)  prime & cement part D to the other end of part A. ( either side of D )

STEP 3: 

(-)  prime & cement part C to either end of part B (only one side of C fits B)

STEP 4: 

(-)  prime & cement part C into part D  (there is only one way C can connect to D)

STEP 5: 

(-)  Drill a 1/4 inch hole in part B  1 inch from part C. 

(-)  Insert part I (2 3/4 inch bolt) through 1/4 inch hole.

STEP 6: 

(-)  Drill a 1/2 inch hole in part F. 

(-)  Insert part H (6 inch bolt) through 1/2 inch hole in part F. 

(-)  Tighten the 2 nuts to the bolt (as pictured).

STEP 7:

(-)  Drill a tiny hole in part A about 3 inches back from part D (for wires to go in)

      NOTE: see step 8 picture for better visual.

(-)  Insert the 2 wires from part J into the hole and assemble the grill ignition switch inside part A.

(-)  Now click the ignition switch and look in part A to make sure you see the spark.

      NOTE: you MUST have spark before moving on. 

STEP 8: 

(-)  Now silicone the grill ignition switch to part D as shown. put the black lip of the switch onto the edge of part D. 

(-)  Add a little silicone in the hole where the 2 wires go into part A.

      NOTE: this is a messy method but it works! 

(-)  After you apply the silicone to your launcher you can dip your finger in a cup of water and smooth it out. (while the silicone is still wet) 

NOTE: You will want to let this silicone dry over night before going on to step 9.

STEP 9: 

(-)  Before you finish with the silicone make sure you can still see the spark. 

(-) Now silicone the switch and wires down completely.

NOTE: You will want to let this silicone dry over night.

Give your new potato launcher a good “once over” for safety!
