Great Progress today. We primed the channel across the top of the firewall and riveted it in place. We made the upper engine mount fittings and match drilled to the side skins. We also worked on the lower shear webs and match drilled the lower angles, including fabricating two for the middle shear webs. We also installed the witches hat on the side walls as well as an angle stiffener. Finally, we began match drilling the lower floor skin between the firewall and the first carry through. We also installed the dashboard. We encountered no problems and the work went well.
