Finished off the drilling for the ELT support shelf and deburred it all. Looking at where it goes, decided the forwards portion might have some lightening holes added that could hold water bottles. Laid that out, cut the 3" holes, deburred these. Put the plastic edging material on them that I used for the inner wing ribs at the flap pushrod access area. Made up a bracket to support the bottom of the bottles and riveted that in place.
