Introduction: How To...build a Spudgun Ignition

About: Renewable energy sources, studio audio effects, tube amps

This is how i made my -sort of- remote controllable spudgun ignition

list of stuff to buy before you start on this project with a high awesomeness level:
piezo bbq-lighter
spark plug
wire
steel wire

tools: a wire stripper
          tape ( yes , tape is a tool)
          hands ( don't lose 'em , they might just come in handy)

Step 1: Drilling

this is the part where you take out your drill , attach a drill bit the size of the threaded part of the spark plug.
Drill a hole in a strong , robust part of the combustion chamber

Step 2: Wiring the Piezo Ignitor

Take the thing apart , but be careful not to damage the internal components.
you will see 2 wires , extend them by attaching a longer wire , and secure with electrical tape.
make sure everything is sturdy and tape it all up
(see picture)

then , tape one wire to the small pin at the end of the sparkplug , and one wire to the o-ring around the threaded part

Step 3: Insert the Spark Plug and Secure

twist the wired sparkplug into it's place.
then take steel wire , turn it around the sparkplug , then turn it around the whole gun and twist the wire , so that it's stuck , once again , look at the picture

Step 4: Testing

here are some pictures of the testing before and after putting it inside the gun



Btw , i'm from Belgium , so my English probably isn't perfect , so if there are any mistakes noticed by you , please alert me!!

    Your English isn't bad. I read plenty of things written by native speakers, man, and you'd have to be pretty awful to not be up to par.

    Great project.

    the spark plug is kind of...useless if you're using a BBQ ignitor....all you need are two nails or pins or anything metal that are close enough to allow a spark to jump the gap when you push the ignitor

    yeah that's true , o no , wait , what is a sparkplug again
    indeed , 2 metal pins close together , it even has extra isolation and threaded wire , so you can jam it in there real tight , instead of hot-glueing your nails

    nice comeback

    hmmm, well , you can see that there is only a small (threaded)endcap on the gun.
    I tested it with a bigger endcap , but the gun was so powerful that it blew the cap off and rammed it into my stomach :P
    it's pretty powerful , because , when i shot it against a 3 inch thick wooden board ( point blanc) it shot right trough :)

    shot something through a 3" thick piece of wood?

    pics or it didn't happen.....you would need a LOT of pressure to do that

    ahhhh, that would make a bit more sense

    the ammo i used : 3 aa batteries , siliconed together in a perfect - barrel shape
    also added a steel pin on top :P
    that's why it shot trough
    ps : the chamber is 50 cm long and the barrel 1meter long
