Today's first project was to double-countersink the aft canopy slide rail support to accept the rivets that will attach it to the rail itself.
I also enlarged the attach holes in both parts to accept the #6 mounting screws. These will be contersunk later.
Next, I fitted the rail support to the fuselage and checked out how it laid in the forward recess. It looked good, so I taped the rail support onto the centerline of the fuselage, and drilled the attach holes into the fuselage skin.
I'll have to crawl into the fuselage next, so I can drill the final, forward mounting hole. There's not enough room to do it from the top.
My plan is to rivet the two rail components together, then have them either chromed or anodized -- along with the side rails and attach screws.
