RH Tip and Lens  ( 4 hrs )

Filled "slot" at aft end of RH Tip (reference earlier recent posts) with epoxy mixed with microlight.  note: previously reinforced inside with cloth/resin anticipating this gap once I cut off 1/4".  I'm sure glad I noticed this on RH Tip, since LH Tip was A-OK at aft end.  Finally, it was time to cut the polycarbonate Lens...which ended up being less traumatic than anticipated.  To prepare, I used a portable electric heater to warm the part up (warm to the touch), since garage was only 63 deg.  Using a dremel with fiber cut off wheel worked well - essentially the material "melts" - there was minimal dust to cut apart the LH/RH thermoformed shell.  I kept the heater on as I trimmed the LH Lens.  Per Van's Step 3, I trimmed front and outbound ends to establish initial fit, then marked and trimmed off perimeter.  Using a small drum sander in dremel allowed me to quickly trim to a line.   I'll hand sand tomorrow to get final fit...then Repeat for RH Lens.   Note:  Scrap pieces allowed me to practice with plastic drills and countersink (Aircraft Tool Supply Zero Flute Countersink 3/32-1/4").   Reference VAF for excellent tips on cutting polycarbonate.
