Peter, i spent half an hour trying to plane a walnut board without much success. The 850 can remove a lot of wood, maybe a bit too much - i had it at around 0.3mm setting and after a few passes it would carve too much wood. Even at 0.1mm it seems to me it carved too much and I coild not make it even on the width of the board.
It felt it would be perfect on a 3-4" wide board, anything widwr, especially a 10-12" was a struggle for me. I'm sure there is some technique to make it work. Can you share your thoughts?
Thanks
