Hollowing Out Wood: An Aerodynamic Advantage
Hollowing out the wood in your chassis can create an aerodynamic advantage by reducing air resistance. By removing excess material from the center of the board, you can create a more streamlined shape that allows the car to cut through the air more efficiently. A 1/4 inch cavity in the center can reduce weight by up to 5%.When hollowing out the wood, be sure to maintain the structural integrity of the chassis by creating supports or ribs to prevent collapse.
This can be achieved by carefully cutting out the center section or by using a router to create a series of narrow channels.
Applying a Thin Coat of Varnish
Applying a thin coat of varnish to your chassis can help reduce weight while maintaining structural integrity. By applying a coat that is only 1-2 mils thick, you can reduce the weight by up to 1%. Additionally, varnish can provide a protective layer against scratches and other forms of damage.When applying varnish, use a high-gloss finish to create a smooth, aerodynamic surface.
Avoid applying too much varnish, as this can create a heavy, uneven surface that can increase weight and air resistance.
