we had a contraption like that in our kitchen. actually, in the 'service verandha'(i have NO idea why the passage outside the kitchen that leads to the garden was called that, but thats what it was) and it was mounted over a shelf. the serrated 'cone' on one end and a rotating handle on the other. another option was the 'aruvamanai'.
This is the only google link that turned up. PPT, but hey! Page 15. I have never used this as it is quite a dangerous contraption. Someone from the India forum may be able to give more detailed info.
Re machines, there is 'Anjali' brand coconut graters for home kitchen use. It is small, very handy and rather plasticy.
Summet's 'Ultra' wet grinder machines come with a coconut grater attachment.
Elgi Ultra website.. I dont think you can get the coconut grater attachment if you buy it in the States because of some weird restriction. Probably because it is deemed unsafe and dangerous by US import laws. It can easily become a weapon. If you annoy the missus, that is.
Tepee, you *can* save the coconut water and I LOVE it! Coconut turns me off, but I *love* the sweet coconut water! At home, its usually broken with a longish knife or with a hammer(as my mother does it). My grandmother used to simply break it by tapping it over the grinding stone. I say 'tap', but I have *never* been able to duplicate that technique. The trick is to do it with one swift blow to allow the first crack to appear or the edges will be jagged. If the crack line' is straight, you get two perfect coconut shell halves. You simply crack it open slightly first and 'drain' the coconut water before splitting it into two halves.
edited to add: found it!!
Anjali coconut scrapper! A non-plastic and metal(iron, probably?) version of this was mounted on top of a shelf so one can grate the coconut halves standing up. It is done in a jiffy!
