Coconut Rubber Samples

I was sleeping over at a friends house last night and talking to my buddy about having to go rip up some coconuts.  However, he told me that his friend (who grows lots of marijuana) uses a coconut fiber mix that he buys locally.  SURE ENOUGH, they sell it by the brick over at Plant It Earth on Divisidaro.  Picked up to bricks for testing.

I also went over to Douglas and Stourgess (a mold making store on Bryant) today to look at some different rubber samples and buy some for making inner shoe soles.

They suggested not using latex rubber as it is supposed to be brushed on layer by layer.  It takes a long time to dry because it is water based (which Gabriel said would be true) but it also tends to discolor, smell funny, and clump up with the coconut.

I got both latex and Urethane rubber just to test them out.

I tested the materials for strength and flexibility by creating a series of samples on a weight ratio- Rubber to CocoFiber.
More Cocofiber and less rubber seems to be the answer which is good because rubber is really expensive.  Also, the denser, less flexible rubber seems to be better.
