Today a little progress was made in the shop … finished up the deburring and smoothing of edges on the remaining fuselage ribs and the center channel’s aft bulkhead. The last thing remaining to do to the F-1204 center channel before priming and paint was to machine countersink eight rivet holes for nutplates which attach onto the center channel’s forward bulkhead.
Machine countersinking one of the eight rivet
holes which will secure four
nutplates onto the center channel’s forward bulkhead
with flush rivets.
The center channel’s aft bulkhead requires some
countersinking as well, so will try to finish that off tomorrow and hopefully begin
dimpling ribs and parts which will contact the side skins.
