Cannon ignition question

[vng21092]

Would this create a spark gap? http://imgur.com/OaGUpCK,N7QRZq1 The first image is the chamber, that is a stripped solid piece of 12 gauge wire. The second image is a screw cap with a bolt and nut on it that will be connected to a wire from a piezo, will this create a spark?

One wire from the piezo to each and it will spark if the gap is small enough. It would seem like a consistent gap is unlikely with that setup.

Looks good, make sure you have around 1/4" between bolt and wire.
