The largest thickened of my spar is slightly less than 1 3/8 inches with 95% at 1 1/4 inch. If I countersink the holes in CS08, I then have 3 inches of space to fit these fatter spars. There should be plenty of room. To countersink the holes, I borrowed a 90 degree angle drill attachment (see photo) and purchased a 1/4 inch pilot countersink bit for that from Aircraft Spruce: http://www.aircraftspruce.com/catalog/topages/stopcountersinkcutters.php This works very well. I've done one and it took about 2 minutes. The structural screws are a little long. I forgot one lesson in ordering parts. Buy a size up and down when you are ordering fairly inexpensive parts. The post cure for the second wing is underway, despite 0F temps outside. All the extra equipment like aileron paddles and control rods are gone to provide a clean tunnel for the fit check. It will stay that way until the spar pin bushings are bonded in place and the dihedral angle is set. Not sure when that will take place with the bitter cold here. It is difficult to get the correct temps inside for curing of Araldite. I would recommend replacing the CS08 fasteners with flush as a matter of course. My logic is margin of safety and if there ever is contact with the spar, there would be a smooth surface. I am even thinking of applying teflon tape to the surface as well. Also - the remote view camera I bought from Walmart for $60 has been invaluable. I have been using it ALL the time! No amateur colonoscopies, however!
