Sec VI – Damn the Delams!!!

Well, I had set a heater up next to the landing brake to aid the layup in curing, which it did, but apparently I set the heater just a little too close because it left me a medium and small-sized set of delaminations.  The delams were both in the corner closest to the heater.  So I pulled out my trusty hand drill and drilled some small holes on the edges of the delams/air bubbles and also rounded up a syringe.  I mixed up some epoxy with fast hardener, filled the syringe and gave the landing brake its due injections.

I also sent out the heavies to take care of the problem, literally.  Since there were a couple of slight, yet unsightly, bubbled glass areas, I weighed down the glass near the offending sites after their injections.

So while my unruly landing brake cured, I went to town on laying up the 1-ply BID onto the 32″ x 48″ sheet of 3/8″ foam.
