Start on the end grain first and use a backer (sacrificial) board. You rout
the end grain and continue right in to the backer board. Of course the
backer board has to be flush with your good piece.

Hope that helps a bit.

I am rounding the corners of some 3/4" hard maple and at times the wood
will split out a small piece where I am turning the corners. Can
someone tell me how to avoid this?

thank you!!
