Well my mill has cracked 100 kg of grain and it is working just as good as ever with no real signs of wear.
Some people thought that maybe jarrah wouldn't cut it but it actually is standing up very well. I haven't progressed plans to motorise it since I can hand grind a 5kg grain bill in about 2 minutes.
And no I haven't updated the wiki page but for people who haven't checked it out, please feel free to visit http://brewiki.org/RollerMill
I haven't checked with the same grain side-by-side with a knurled style mill but I speculate that the smooth rollers tend to leave the grain more intact. Also due to the positive drive to the second roller, there is less shear applied to the grain. I have set my brewhouse efficiency to 85%, I think the mill is helping me get good extraction.
