How to make coconut oil without any food processor? How can I make coconut oil without having access to any food processors? I do not own any blenders, juicers, coffee grinders or anything like that and I am not looking to buy one, so I want to know if that's possible.

I would also like to know how efficient the methods you will mention are? Would I get around 66g of coconut oil per 100g of fresh coconut meat (as is the approximate content of fats in fresh coconut meat)? And if not, how much would I get approximately and how to improve the amount that I can get (again, without food processors)?
This is not something I have done, so I don't have all the answers you're looking for. This is, however, something my mother in law (Sri Lankan) does with old coconuts. It's something that's been done in Sri Lanka and other tropical countries for hundreds if not thousands of years. 

She'll split the coconuts open and pry out the flesh, then leave the flesh out in the sun until it dries out. Then she takes it to a mill to grind, but at this point, you could grind it yourself. You could use a mortar &amp; pestle or anything like that to grind it as finely as you can. Then squeeze the flesh until you get oil out of it.

I don't know how much oil will be produced, though.
