Another milestone in the Nemesis R1 build occurred earlier this week where the entire chassis was 3D scanned. Before performing the scan the entire rear section of the car was removed and a full new rear configuration created in order to fit the Subaru EJ207 and STI six speed transmission. With this new configuration in place it was time to scan the chassis to move the project to the next step.
For the shifting mechanism of the vehicle we’re using a Factory Five Subaru kit to cap of the rear driveshaft (not installed yet) along with the cable shifting linkage that comes with their kit. Cusco mounts were used for mounting the engine and transmission . For now we added some trailing steel to connect the under tray and diffuser which might end up changing depending on the final model.
3D scanning the chassis allows us to move the physical structure into 3D space where we can then model different body panels to fit around the dimensions of the vehicle. This is where we take the inspirational 2D drawings and try and capture the essence in 3D space while working with the limitations of actual dimensions.
To get an idea of spacing and height of the driver we also placed the custom embroidered Corbeau UK seat approximately where it will be positioned along with its seat rails. From here we’ll design the height of the rear section of the car and build a roll bar to fit the design.
After everything was setup it was time for all of the thousands of target stickers! These are required to give the computer a position in space to know how to scan the chassis. After all the stickers are on the target you need to be extra careful not to bump or move things so that the computer doesn’t get too confused.
The result of the scanning is a 3D model that is accurate down to the width of a human hair! Next step is creating the first rough 3D model for the distinctive shapes of the Nemesis R1 body panels 🙂
