You will see that I have already cut out a section from a Wellington fuselage to insert into another fuselage to lengthening it by the required amount. Some work will be required at the join to the wing to smooth it out.
Also visible are a casting I made from a Lancaster upper turret (courtesy of F-toys model) fairing that I will add to the spine of the fuselage for the upper turret on the Warwick.
A resin lifeboat is also in the picture as are two completed Warwick wings.
This picture shows how I cut up a number of Wellington wings and used the pieces like a jigsaw puzzle to make the appropriate length and increasing chord for a Warwick wing:
The wings are the same from the outside of the engine to the wing tip (on the wellington) with the Warwick having an extra 3 feet (6mm) added to the outside of the engine for the wing length.
Here is the wing once glued, puttied and sanded:
The Wellington's nacelle has been removed as the Warwicks was all below the wing with the engine being mostly under the wing unlike the Wellington which was centred on the wing when looked at from the front.
