Thanks for the comments,
I forgot to say that this is the first washerless design that I have done.
Dave Clark showed me the design for a washerless type of setup. I think its pretty slick.

Basicly we're relieving the liner in areas cirtical for blade clearance and leaving a raised area for the washer. Leaves no gap at the top and stabilizes the blade well due to a larger surface area than a washer.
