    45ss Con Rod Chamfer

    Xmas project
    I'm rebuilding a 45 ss and only have one original con rod (no oil holes).

    http://www.apba.org/sites/all/files/...TION041013.pdf says "... chamfering the oil holes..." is allowed. Another blog/forum... suggested that without the chamfer the fishing engine rods break.

    My question is how big a chamfer and how best to make it. I was thinking about using a dremel with a conical stone, high speed, low pressure and lots of oil to make the surface as smooth (micro crack free as possible).

    Any one have experience with this?
