Chapman Skateboards produces skateboard decks since 1991 and is proud to take part in the history of skateboarding in the US.
In a wonderful video they show the mastery of creating a skateboard from the beginning to the end:
One Skateboard At A Time from Chapman Skateboards on Vimeo.
Early morning
Machines are ready
Materials too
Work starts
To cut out the famous shape
And make hundreds of it
Of which each one is special
Because of the careful work of each person
To make each deck, one deck at a time
