I'm sure this has been discussed elsewhere on slap but the search function didn't turn anything up for me.
Who made the first seven-ply skateboard? When?
Shalom.
p.s. I got to thinking about this because Eames Demetrios came to my town for a lecture on the furniture of his grandparents, Ray and Charles Eames. They developed technology for molding plywood before and during WWII. They designed wood splints for the US military during the war.
After the war they became world-famous for their modernist furniture design.
e.g. The Eames Lounge Chair
The reason I bring this up is that they made this stuff in Venice, California and were making furniture with seven plies of Canadian maple.
My skater buddies and I were super intrigued by the implications of this and asked Mr. Demetrios about this. He smiled and claimed that at some point in the 70's, before they moved production to Michigan, one of their large machines was stolen, apparently by some skaters who started up a skateboard wood shop.
