Firewall and engine mount

Drilled engine mount holes through the firewall today and reamed them. Teamed out the bolt holes in the fuselage frame, and the engine mount,

Drilled, teamed and deburred the AN3 bolt-holes to bolt the firewall to the frame.

Drilled out two rivets from the firewall that were touching the frame and reversed them with a flush rivet.

Also bought a beading roller and put beading on the rear bulkhead. Not really happy with the results as it leaves the sheet aluminum wavy.
