38-02 trimming Upper & Lower Cowls

OK, I’m back.  10 consecutive nights in the ER left me with a severe case of RV-12 withdrawal.  I got back to work by tackling the cowling.  As you recall, I had finished up with the oil radiator, but it  is mounted on the air duct that is mounted inside the cowl.  I had deferred the cowling from its schedule slot (chap 38) due to the advice of hanging the engine and letting its weight “settle” for a few weeks before fitting the cowl.  Made sense to me, so that’s what I did.  First picture:  me, getting ready to attack the fiberglass.  I elected to use a reinforced cutting wheel on a dremel to do the major cuts and a 1 cm sanding drum for medium abrasions/shaping and the traditional 80 grit sandpaper on a block for detailed finish sanding (shaping work only—not surface sanding!)
