Aircraft construction is perfect for early style hot rods for several reasons, not the least of which is aesthetics. Fighter planes and race cars are spare creatures: what doesn't go into them doesn't require power to move around. As a result they look lean and mean.
But minimalist machines needn't forego creature comforts; they just have to reflect that less-is-more philosophy. For example, Frank Wallic said he figured that conventional carpet would look out of place in an interior that looked more like a cockpit. At the same time he said he needed something to keep his feet from sliding around on the slick floor. At least he needed a way to protect the varnished floorboards from abuse.
So he drew upon the construction techniques he'd learned by making aircraft-style panels to whip up a set of very simple heel boards. He also took the project as an opportunity to use some real neat rubber matting that he found at Restoration Specialties and Supply.
Wallic offered three construction techniques: one with a riveted ring, another that folds over itself, and a simple non-riveted type. They vary in difficulty, but even the most involved style is within the grasp of anyone willing to invest themselves with a little creative effort and a few inexpensive tools.
