Opulence, I has it...
I dis-assembled my fuse today to begin the deburring and dimpling. I have a question regarding the overlap of the 827-1/826-1/890-1 and 804 center section flanges...
I thought the 827/826 assembly sandwhiched between the 804 flanges and the forward floor (890). But the instructions are saying to machine countersink the 890 which will accept dimples of the 826/827...implying that they will not be between the flange and the 890. This then would leave an exposed edge facing forward, into the airflow.
Then I remembered there is still another lower skin on the forward fuse (no part number handy), below the floor, that would cover this exposed edge, and also seat into those 826/827 dimples...at least the forward row.
So, now I'm totally confused and discombobulated. I wanted to check with y'all before I countersink or dimple something in error. I think I'm getting this correct from the plans, but for my own sanity, please confirm this sequence...from bottom up (out to in) if the fuse was finished and standing upright:
outer skin (dimpled)
826/827 (dimpled)
890 (c-sunk)
804 flanges (possibly partially c-sunk)
Thanks!
