Cozy Update – April 30, 2016

I used a combination of hand saws and the dremel tool for trimming the aft end of the fuselage sides.


I trimmed the aft end of the right fuselage side then trimmed the top longerons at the rear of both fuselage sides.  At the aft end I ensured that I had at least 0.5″ of additional length in the longerons from the aft trim lines.

Lastly, I removed the glass and foam in the 8.7″ x 5.5″ areas where the centrespar will mount.

Trimming the fuselage sides.



I used a coping saw and small hand saw with a hack saw blade to trim the left front fuselage side then the right front fuselage side. The front foam/fiberglass and longerons were both trimmed.


A carpenters square was clamped in place to avoid cutting inboard of the trim lines.  The fiberglass is hard on the cutting blades so I procured some additional dremel and hand saw blades.


A dremel cutter and the hand saw were used to start trimming the left rear of the fuselage. The foam/fiberglass was trimmed but the longerons are not to be cut.
