I’ve been staring at the sawdust pile, then looking over to the chipboard stock (particle board), then back to the sawdust. Back to the chipboard, back to the sawdust, etc..
I’m sure one of the reasons that thick, solid, plastic ‘table’ tops aren’t used ubiquitously is that it would be hella costly. Chipboard makers get around this by using only a very little bit of plastic (resin glue) to hold wood chips together, and include a lot of air spaces too. I don’t have a factory to process my sawdust in such a regulated way, but what if i could replace a lot of the volume of a worktop that i might cast in solid plastic myself with wood chips? How strong would my product be compared to what the same money (as the casting resin) would get me in a store-bought work surface? Or conversely, how much would a home-made equivalent to the store-bought work surface cost me to make?
My initial plan of action for this casting task would be:
Has someone tried anything like this?
Cast upon glass, the work surface should be dead flat. It would be dimensionally stable; hard; hefty (good for not moving around); more robust than airy chipboard; and could be shaped using many a woodworking method. So i’m seeing only positives for my application.
If this is possible I’m imagining it could be a very useful approach to very many folks. Every woodworker abandoning centuries of tradition of laminating fine wood into a workbench slab, and instead casting their own cheaper better alternative. We will call ourselves cast-aways. High on the fumes from our workbenches and ecstatic over the new tool we bought with the money we saved. Or is this all just blasphemy?
