Mostly it&#8217;s the mess, but the big minus is the cure time.     I filled the ends of the empennage tips with foam, laid up some fiberglass on each side to stiffen it, then slathered on a nice frosting of micro.  I had to take another run at the micro to fill the low spots, but this time I mixed it a little wet.   Of course, this necessitates putting the pieces in a position that will allow the filler to flow out flat along the backside, like so:<\/p>\n<p><img src = \"http:\/\/stjohn.openbar.com\/airplane\/images\/12-4-2010\/IMG_0713.JPG\"><\/img><br \/>\nThis tree, cobbled together with clamps, tongue depressors, and scrap angle, allowed the filler to behave as if it was cast in a mold.   There&#8217;s still a modicum of shaping after this, but these are nearly done.<\/p>\n<p>But I had to do something else while this was curing, so I tackled the thing I know I have the resources for.  A while back, I verified that the strobe unit worked.  Now it was time to stick it in the plane.   I&#8217;m going to worry about wire runs later, but I mounted it just behind the baggage comparment bulkhead on the passenger&#8217;s side.   This is a fairly common location, and will do the job nicely.   But I&#8217;m out of practice with metal.   I went through three plates before I got one that fit right.  There are two pieces of angle a little wider than the strobe head, fixed to the J-stringers between the longeron and the floor.   Drilling them to the J-stringers was not fun, and neither was riveting them.   But they did eventually go in.   Here&#8217;s a shot of one of the angles clecoed in:<\/p>\n<p><img src = \"http:\/\/stjohn.openbar.com\/airplane\/images\/12-4-2010\/IMG_0714.JPG\"><\/img><\/p>\n<p>And this with everything assembled and riveted:<\/p>\n<p><img src = \"http:\/\/stjohn.openbar.com\/airplane\/images\/12-4-2010\/IMG_0715.JPG\"><\/img><\/p>\n","protected":false},"excerpt":{"rendered":"<p>4 hours.
