Fuselage bulkhead placement

The lower half of the fuselage was leveled fore and aft and side to side, and then it was fixed in place in its cradle using Bondo. Working forward, the engine firewall, landing gear pockets, gear bulkhead, cable conduits, keel, and canard bulkhead (all pre-fabricated parts) were placed in their respective positions, trimmed where necessary to fit, and their positions marked on the fuselage. Holes were drilled through the bulkhead flanges and the fuselage inner skin for later clecos.

The area of the fuselage close to the NLG door hinges was protected with aluminum tape.  Next, the NLG door part was glued into place with wood sticks and hot glue.  The NLG door hinges were alined and spaced correctly using a piece of all-thread, and then cemented into place with resin+cabosil+flox (cabo/flox).

Glassing wing bottoms

With the micro starting to get tacky, the final fill and fair of gaps and transitions was done with a thick mixture of resin+cabosil (cabo).  A length of triax was cut and draped over the wing, and smoothed out by hand.  Resin was squeegeed and worked into the glass to wet it out completely.  Peel ply and weights were used in select places to keep the surface flat.  The trailing edge glass needed to be periodically forced into a sharp edge by stippling with a brush.

Prepping wings for fiberglass

The trailing edge foam was cut back to make an even and straight edge.  Ailerons were cut out using a long hotwire foam cutter, and then the foam was replaced in the wing.  The control surfaces will be cut back out later, after the wing is glassed, filled, and primed. A hole was melted through the foam with a soldering gun to the cable conduit in the leading edge foam blocks.  The VHF NAV antennas were placed on the wing and glued into place, with the cable and balun routed to the wing root.  The foam surface was sanded lightly to smooth the gaps and to fair all the edges.  Micro was spread over the entire wing and squeegeed into the foam.  Micro was used to fill gaps and holes and to fair all transitions.

Nose gear doors

I used a jigsaw to cut out the hole in the lower fuselage where the nose landing gear doors will go.  An inset is molded into the fuselage in the right shape and location – care was take to leave an even flange around the opening. The NLG doors are supplied as one piece (to be separated later). These had to be sanded to fit the NLG opening with about 1/8″ clearance all around.  The jigsaw was used to cut out four NLG door hinges from a thick piece of fiberglass layup – slow, blade-dulling work.
