Hello Roy
and thanks for calling.
You are privileged to live in Australia. They have developed a mustard species, that can be used as human vegetable oil raw material. A company Yandilla is specialized to produce various mustard seed oils mainly for human consumption. Steven Hobbs is a farmer who grows mustard for bio-diesel and has experience and a small oilpress on that field. Steven visited my farm 4 years ago and so are you also wellcome to do.
But first, contact Steven and the company Yandilla - they may have some older but good mills for reasonable price. If I send a press to you for nothing the costs may anyway become quite high.
About my tests; I have tried to asses the risk for a farmer who is compelled to use raw unestherized mustard seed oil during some crisis ( war etc. )
It is cool even cold here in Finland, but minus 15 degrees Centigrade is still possible to run a car in my system.
What part of Finland was your father's home region ? Please come and see this nice country and visit my farm too !
