At the start of the build process, my group of friends and I were thinking about how we can create a concave shape. We came up with a concave wood template. We would have one pre-cut block to trace with to make sure the seams were consistent. All of these pieces of wood were nailed and glued together to create a mold that we could use later to compress the layers of wood and fiberglass to create a concave shape.

After all of the pieces of wood were cut to shape, we began to match them together as best we could (this was because we cut the wood by hand and it wasn't perfect). A makerspace would have helped. After gluing the mold together, we began to notice imperfections. To fix the uneven shape, we started to chisel away at the mold to make it as smooth as possible.

The chiseling got rid of all the major imperfections, but there were still some small bumps in the wood. To fix that, we used wood filler and put a layer of it over the mold, shaping it to match the curvature. We sanded the mold to make it smooth. The mold was complete.

None of us knew how to work with fiberglass, so we got a roll of fiberglass, and we played around with it. We made multiple samples to see what works best. 

Once all the layers were combined, we waited for the glue to dry. 

After mounting the wheels, the longboard was complete. We were ready to test it out.
