“The first refined skateboard came out around 1963 or 64. It was a hard, inflexible board and the wheels were stone (or something like that) on an axle that allowed the wheels to turn in response to the left or right weighting on the board.”
We made our own boards. Laminating them for texture and color. Stained and varnished ... NEVER painted. We got our wheels from the local roller skating rink. I don’t remember what the material was but it was not stone.
You're right, it wasn't stone......
This is the best picture of my skateboard that I could find as well as a link to one for sale on Ebay........Evidently the wheels were made of clay, which didn't really matter when your only surface was hills.....LOL!
