SpudFiles

I am currently in the proces of making my 2nd spud gun but this time im making it out of metal!!!
I found an old grease gun to use for the chamber..
One end has a hole in it so u can pump the gun so i filed this out big enough to fit a piece of gall pipe that i found(a bit bigger than a average marble)
i have welded the gall to the now end cap (took a bit of effort but it has came up alright)
Now i am going to jsut weld a base on it wih a bit of 4mm steel i found..
But before i do this i need to put the spark in it.. I only wont something simple preffibley a bbq ignitor nothing fancy..
Will the sparker work in metal chamber i want to put two scewrs in it like my oother 1..

You have to isolate to wires. If they are shielded just run them in the chamber and keep the spark away from the chamber walls.

You can use one wire that is insulated as the "hot" wire, and then use the chamber walls as the "ground".

I.E. - one wire is well insulated from the chamber walls (via rubber coating, epoxy, etc.... or you can use a spark plug), and the other wire is simply soldered to a spot on the metal chamber. The spark will jump from the hot wire to the chamber wall, or in the case of a spark plug, the electrode to core.

Why is this in the Cannon Showcase??
