A Laser cut wood body for the highest speed possible.
Speed comes from finding the best trade off between:
1. Equal weight on the back wheels
2. keep weight on DFW low but not too low.
3. Keep thickness of body to 1/4″
4. Make body as light as possible while still being strong enough to resist any bending or vibration during a run.
Our engineering improvements to the typical laser cut body are as follows:
A. Offset the weight behind the back axle to be closer to the DFW.
B. the front axle is cut with the grain to give a much stronger overall construction and also allow you to set the wheelbase to whatever you want.
C., We laser cut, but leave attached, a 1/16″ strip on the DFW side. This allows a solid fit in your drill fixture while drilling the front axle holes, and if desired can be removed to modify the DFW distance from the rail to get the back wheels centered on the rail.
D. The 1/16″ strip can be cut with scissors to make two ribs to further enhance the strength of the body. We suggest one right in the nose, and another one mid cavity between the axles.
For best results, lightly sand the laser burned and hardened wood before drilling or gluing.
Finish up with the smaller bars and/or cubes to bring the weight
up to 5 oz and fine tune COG for speed and stability
