|Le sable et sa préparation
|Sand and it's preparation
Here is a weird contraption of mine to break the sand blocks that
I cut a piece of the top blade and the moving one to shake the sand little at the time.
This will be evolving into a drawer type filter system suspended from the ceiling.
The cover on top is an effort to
keep the big clumps in when they get grinded.
I made those wood washer myself :)
Here is Jean-Pierre from Enseignes
Herem Inc. preparing petro-bond from a kit.
He buys the oil seperately and save on shipping. The resulting sand is really nice.
