Paintball/Airsoft Mine Project

I found this recipe online and modified it to my own needs
Ingredients:

• 4" PVC cleanout plug
• 4" PVC female cleanout adapter
• 4" PVC cap
• PVC cement
• 1/2" PVC piping (at least 6")
• 3/4'' PVC piping (at least 6")
• 1" screw
• a nut & bolt (just long enough to go through 1/2" PVC)
• CO² cartridges used in airsoft guns
• PVC cutter (is nice but can use a hack saw too) {not pictured}
• Power drill
• 1/8" drill bit
• 3/16" drill bit
• 5/16" drill bit
• 3/4" spade bit
  
• Baby powder (talcum powder is too hard to find, baby powder is cheap)

The original design called for paint to be sprayed out. That worked for his design. In the Army we don't put paint in our simulated mines for training, we use baby powder. Paint is just too messy.



Step One: Use PVC cement and bond the 4" PVC female cleanout adapter and 4" PVC cap together. Make it a tight seal. No gap between the two.



Step Two: Cut a 3" piece of 3/4" PVC piping. Drill holes at base where CO2 will escape. I drilled 4 holes with the 5/16" bit.



Step Three: Drill Pilot hole in PVC cap (dead center) and sink in 1" screw. My screw is a hex screw with a rubber gasket. Good tight seal.



Step Four: Use PVC cement and glue 3/4" PVC piping piece dead center inside the 4" Female cleanout adapter/4" Cap thingy with the holes down at bottom closest to PVC cement.



Step Five: 4" PVC cleanout plug needs a hole dead center with the 3/4" spade. This will be for the 1/2" PVC piping to go through. You will need to scrape some PVC out because it won't fit without you helping it. Then with the 5/16" bit drill 8 holes for the powder to escape.



Step Six: Glue 1/2" cap to 1/2" PVC piece (about 3 1/2"). Drill hole for nut and bolt inside mine. This is to prevent the plunger coming out of mine.



Step Seven: Drill hole between cap and mine itself in the plunger. This is for the safety pin. I made my pin from a BudLight bottle cap.



Step Eight: Camoflage your mine as your region ground color matches best. Put Powder in mine, screw tight, bury in ground, pull pin, talk a friend into stepping on it for a test.
