Pictures of static spark gap with carriage bolts?

Well, my first "modern" tesla coil is almost ready to be fired up for the 
first time. Over the weekend I built the tank cap circuit, base, spark gap 
and varnished the coil.

Because my TC is so simple (360w) I am using a simple spark gap using two 
5/16" carriage bolts mounted on right angle brackets. The initial gap is 
right now set to about 1/4" but of course I will probably have to adjust it 
the first time.

I was wondering what other's carriage bolt spark gaps look like (so I can 
compare with mine)? I have seen a ton of pipe gaps, multi-gaps, etc but 
really no good pictures of a simple gap using carriage bolts. Any out 
there? BTW, I have taken picture of my TC during the construction phase and 
will post pictures as well as video to my web site (www.joecool-dot-org) as 
soon as I get it working.
