did all the fitting and attaching
with the wings still in the jig.
You can eyeball the holes
for the rivets on the ends of the
W-816 and W-818 pushrods, or if you want them perfect, you can measure
around with a piece of paper. Wrap
a piece of scrap paper around the rod and mark where the end overlaps. This will give you the
circumference of the rod.
Now divide the measurement by four.
Make three more marks on your
paper each spaced ¼ of the circumference from the first mark, and you
now have four equally spaced marks for your rivets.
Since these rivets don’t
pass all the way through the rod, you can get away with hand drilling. You
can still use the drill press if you want to, that much accuracy just
isn’t required here.
