Cut backing plates out of .063 aluminum sheet to be used to provide greater strength to the mount points for the cowl flap mechanism to the firewall. Layed-out and match-drilled the plates to the firewall. Had to stop for the day when my back began acting up from a mis-step I had a few days back while using the snow-blower to clear snow in the driveway. Was on a roll with this assembly too!!!
Nut-plates will be installed later, and also a stiffening bend will be added to the long edges.
