Thanks for the advise guys.
Arthur Johnson here in Australia sent me some pix of his which cleared it all
up for me. Looks like I was trying to over complicate things, again!!!

My side stringers taper down and end forward of the start of the horiz stabilizer.
That makes for a flat appearance at the tail.

Subject: Pietenpol-List: External stringers
Hi All,
Just wanting to know what you guys have done at the tail end with the external
stringers for the fabric stand off. I was trying to avoid adding the 1/4"x1/2"
stringer to both sides of the vertical section of the tail to prevent having
a "fat" tail post leading into a "skinny" rudder but having pondered about
it for a day, seem to think it's the easiest option.
Any advise/criticism welcome.

William:
A few yrs back I flew w/ a man who owned several commercial fishing vessels.
During Tuna season we would fly a couple hundred miles off shore in his
straight tail 172 w/ an oddly pink interior. The plane was equipped with an
extra tank in place of the aft seat allowing for an 8 hr operation. The idea
being that we would spot the tuna from the air and mark the spot w/ a dye
marker, then via marine radio direct the boats already on station to the red
plume. The marker bombs consisted of an 8 inch square piece of newspaper
that would contain about 3 table spoons of neon red dye and a small pebble.
The marker bombs were tied up w/ a rubber band so that the selvage of the
paper would be rather like a feathers on a badminton shuttle cock. The were
quite accurate. Unfortunately they were also fragile. And thus when a little
less than careful the marker bombs would come apart as we attempted to
launch them out the open window. This of course explained the reason for the
rather feminine interior dcor of the old 172. The stuff never came out of
the old white vinyl interior.

We used to use flour bombs in a Texas town using a barrel. It was fun, but
extremely difficult to hit that barrel. Anyway, we used brown sacks filled
with about 1/3 of flour. We tied the bags with one string, loosely, so that
the sack would easily spill its content when it hit the ground or the
barrel. Be sure and take them out of the aircraft when going into Mexico and
back. It is terribly embarrasing.
