I finally got a table saw this weekend, I picked the Ryobi BT3100 and I'm
pretty impressed with, bang for the buck. The only trouble I'm having is
that the riving knife seems pretty flimsy and it wobbles a lot. Moreover,
no arrangement of the shims aligns it properly with the saw blade. I've got
all my shims on one side and it's still off and there's no more to move to
fix it! Anybody else encountered this?
