I've had troubles with carbon tracking through wood (mainly because of not
thinking). There are a lot of
areas which will not have a problem using wood, but at places like the
spark gap and primary, something
must be done to prevent the path through the wood. Basically, find a way to
insulate wooden structures
from hv lines, brackets, primary, etc..

My primary is oak, however, I use a plexiglas insulated strip between
primary and runners and use
tie-wraps to hold the primary in place. I've once used wood in a spark gap
(never again).

Here's a photo of my primary:
