Since we last spoke some thought has tended toward this idea.
I was by the hardware store the other day and happened upon a bamboo sink
Can't be too unstable under high humidity. Though understandably it was well finished with lacquer of some kind. I imagine these days it's likely to be urethane, but it wasn't giving up its secrets.
Looking at the need to precisely locate the front and rear mechanical systems on the tub i came up with a relatively simple, almost idiot proof idea.
Plans are provided for precise dimensions of bulkheads and how to build them with precisely located hardpoints for the subframe mounts, these would then be joined by a supplied torsion tube. The various other panels would be a more freeform afair that can be completed as each builder chooses. This has the benefit of making the fit customized for each person.
But the more i think about it the more i'm leaning towards building a tub and doling them out. It makes the supply of parts less of a hassle, and we all know how much development needs to go into a car outside of the sourcing of raw materials for the main chassis unit.
It's times like these i'm reminded that I live almost downtown without a workshop or private garage that could be used as such. I love it, but building things is a pain. Especially large things.
so in usual fashion i end with a question:
in the context of this kind of project what would you be willing to spend on the main chassis component, the tub
-as a flat pack/set of plans
-as a pre built tub
