HALL BULLDOG

The Hall Bulldog, a 1930s racing aircraft, carries a bold and uncompromising personality. Tight proportions, gull wing geometry, and a compact fuselage that feels carved rather than drawn.

When Jim Burke approached me to recreate it as a full-scale replica, the challenge was immediate: no complete technical drawings existed. Only vintage photographs, often distorted, incomplete, and stripped of reliable lens data.

This was not styling. It was aviation archaeology.

The process began with rigorous photographic analysis. Distortion-free areas of historical images were isolated to reconstruct accurate 2D three-views, which then evolved into a precise 3D model.

Each photograph was treated as a calibrated lens. By matching archival images to virtual 3D cameras and adjusting parameters until geometry aligned, perspective errors and optical distortion were progressively eliminated.

The workflow was iterative and disciplined:
modeling, camera matching, correction, refinement, validation.
It took fifteen full iterations to achieve a coherent match between digital reconstruction and photographic archive.

Once the external surfaces reached reliable accuracy, the 3D model was translated into technical format and shared with Kevin Kimball, whose expertise in vintage racers allowed the development of the internal tubular frame.

Here, digital skin meets structural engineering. The goal was never aesthetic nostalgia, but technical integrity and historical respect.

To position rivets, panels, and structural details accurately, I developed a dedicated dimensional mapping system. A custom “ruler texture” was applied across fuselage and wings to ensure coherence throughout the aircraft.

When working only from 1930s photography, every millimeter must be earned.

The Hall Bulldog synthesizes the foundations of my path:
a lifelong fascination with racing aircraft, modeling as verification, technical rigor, and the ability to translate images into geometry.

Between a faded photograph and a steel tube structure, there can be a bridge. That bridge is built with discipline, intuition, and iteration. When the proportions finally align, it is not nostalgia. It is geometry restored to life.
