<DIV>Gee whiz, Bobby, I thought I was the only one.</DIV>

<DIV>Wayne, take your square and add its mirror image. You will have a right
isosceles triangle with the base being the hypotenuse and the vertical
center line bissecting the triangle. Draw several parallel lines to
the hypotenuse and they will all be at right angles to the
vertical bissector. These serve to line up the stab at the same time the fin
post is being aligned. Essentially it becomes an inverted T</DIV>

<DIV>I made mine from a 1/8" piece of plexiglas. It is fairly large right
triangle with a hypotenuse some 28" long. It is a super tool for locating
the stab and fin exactly at 90 degress to each other. With a little more
ingenuity, it serves as a fixture to hold things lined up while the glue
cures</DIV>
