Well last week I was struggling with a milling horribly twisted board and the flat jack plane blade I had just wasn't doing it. So after month of putting it off I finally bit the bullet and radiused my first plane blade (A spare blade I had). Following some direction from Chris Schwarz on Roy Underhill's Show The Woodwright's Shop (right about the 15minute mark). It took me only about a half hour to do and not the most beuityful thing but it works very well.
