Hi all,
Possibly a fiberglass newbie question here. I'm using Skybolts and a Sam James cowl. I riveted on the fasteners to the firewall last weekend, and have done a loose fit of my upper and bottom cowl halves. Basically just dropped the top half on top of my baffle rubber.
Everything looks good to start. But since the gap thickness between the fastener surface and the top forward fuselage is one skin thickness (0.032"?), clearly the cowl thickness is much more, and I end up with a huge intersection jump.
How much should I bevel down the inner firewall edges of the cowl for proper fit? Or is beveling really more just for visual cleanliness? Some part of me worries about beveling down too far, and not leaving enough along the edge of the cowl for structural holding by the fasteners.
