1. Used tape to extend the lines on the canopy and find the upper hole locations for the skirt. Marked them with white paint marker.
2. Drilled and clecoed the remaining upper attach holes in the skirt.
3. Used an extended drill bit to reach inside the cockpit and back-drill a locator hole in the skirt for the canopy handle..
4. Filed out the hole to match the diameter of the steel handle guide in the frame.
5. Test-fit the interior and exterior canopy handles. I noted with dismay that the custom handle I'd purchased from JDAir several years ago, and had custom-engraved, does not seem like it will work on an RV-8 because the front edge of the handle will strike the canopy and the skirt when it's rotated 90 degrees. I'll need to study this problem a bit further, but in the meantime I ordered a raw, stock canopy handle from Vans Aircraft (which has its point of rotation far enough forward that it will not strike the canopy).
