Building Seamaster Day 16: Wing, Floats & Push Rods

Rounding of Leading Edge

On April 14th I did a fair bit of work on the wing and a little bit on the fuselage.

On the wing the supports were glued into place.  This is top and bottom for both wing tips and provides stability for the wing tip to prevent over flexing, etc.  You can tell in looking at the leading edge of the picture below followed by the leading edge in the featured image at the top that I rounded the leading edge to get the aerodynamics going.  This involved a lot of sanding.  Key here is to wrap the sand paper around the edge and work it back and forth pulling down and away from the edge back and forth to get the rounded effect desired.

This day I also glued the bottom, light balsa, of the floats to the sides.  Eventually the floats will be fiber glassed and special paint applied to make them water proof as these will be placed out on the wings for flotation in the water.

Making sure the push rods are long enough (and casing cut back to allow movement of the inner rod) for the rudder and elevator of the aircraft to where the servos are mounted.

Building Seamaster Day 15: Fuselage Bottom + Wing Tips

On April 12th I worked on the wing and the fuselage.  I glued the bottom mid-section of the fuselage in place which involved using glue along the edges to hold it to the fuselage as well as along the front edge to hold the bottom the flat surface it butts up against in the front.  It is then clamped and held in place while it dries.

As seen in the two pictures below I glued the two balsa wing tip forms into place.  There is glue along the straight left edge of the wing tip form to adhere it to the side of the outer rib as well as on the wood pieces where it is sliding between on the front and back of the wing.  This is to ensure it is glued into place and is being held by clamps while the glue dries.
