Yes that is correct the strapping would run eave-to-ridge.... Are there
any products out there that I could slide in under the current
sheathing to create channels? It would be nice to just have to go over
the old sheathing with plywood and not have all of the problems
associated with spacing the plywood up. I was wondering if I could
remove some of the old sheahing and slide some kind of duct in between
the sheathing and the insulation???

I am in the process of stripping old shingles, putting plywood over old
sheathing and adding new shingles. The roof is over an attic that was
converted into a bedroom. The current roof has a ridge vent but no
Soffet vents. I was told that the best way to add a soffet vent is to
put strapping down between the plywood and old sheathing in order to
create a ventilation space. Then cut holes in the top of the old
sheating over the eaves. Then put he plywood down, cap the space and
add the vents on the bottom side of the eaves. Is this the correct way
to do this???

It's *A* correct way to do it, although I suspect that
using something thicker than strapping would get you better
airflow. (The strapping is running eave-to-ridge, right?
not gable-to-gable?)
