I feel kind of stupid I didn't notice this earlier. I'm working on #8 today and I've been struggling with my grind lines matching, just like all newbies. But, problem wasn't alignment, I'm keeping them even. The top little turnout line never matches side to side. One side has a nice little radius, other is squared off.
Finally noticed why today, insert big DUH, it's my platen! I built my own grinder and used a piece of 4x4 angle iron for the platen. The factory corner has a radius, the other side I milled down to a 2" width. Of course it has a nice sharp edge, never thought about it because I'd never ground any blades. Moral: if you make your own platen, make both sides have the exact same edge radius.
