In you description, as you don't describe the structure, I see just one
fatal problem: WOOD. Wood is -not- an insulator at all for high voltages.
If the NST terminals were in contact with wood, very probably there
is a carbon track formed that is short-circuiting everything.
The first thing to do is to see if your transformer produces some
output with its terminals floating in the air.
