Thanks Gamera! The work continues...
I finally sat down and forced myself to cut out the 6 fuselage side gun position window frames. I had a devil of a time cutting the window opening on the first one, but like I say I do things the hard way first.
Hard Way = Cut opening and trim with knife, hoping knife won't slip or make the dreaded "k-k-k-k" skip with resultant rough/faceted edges that propagate fractures. I lost 2 window frames that way.
Easy Way = Drill pilot holes, use knife to butcher out a rough cut, then refine opening size and shape with elliptical cross section file. Easy. 5 done in one sitting.
The window openings were backed with 0.010" sheet plastic. I used the heat form buck to trace out the rough shape to get a drop-fit into the backside of the frame. Again, easy.
There are 2 odd shaped side gun postions and one tail position at the back that need to be fabricated and installed. I have those figured out already. Some rain channels also go back there.
Those holes on the landing gear sponson are for little wire grab handles.
