BIODIESEL PAGE
This page will eventually document our biodiesel experiments.
We are currently in the hunter/gatherer stage.
At the moment, we are leaning towards straight vegetable oil conversions due to the reluctance of chemical suppliers to let us have methanol in reasonably priced batches to justify the expense in making the fuel.
Best UK site I know to is this one http://www.veggiepower.org.uk/ John Nicolson's conversion (which is detailed on this site) is exactly what we had in mind
I can also recommend the "book", I find it compelling reading.
Sorry I can't offer you more just yet.
