I did the edge prep on the canopy rails today and then alodined the areas that will overlap. The next thing that I did was rivet the forward and aft sections together. There was another builder on the RV-List that was wondering how to do this after the canopy rails were already riveted to the fuselage. I guess in that case I would just use blind rivets. But, since he gave me the heads-up, I decided to rivet these together on the bench and use solid rivets.
