Re: Krenov style plane jams

Warren in Lancaster, PA
I have used the same trying plane on every board since January 1979. The cutting angle is 43, the angle on the cap iron is 80 for a total of 123 degrees. The angle on the wear is 15 degrees from perpendicular (105 degrees).

One guru has said that the angle on the cap iron plus the bed angle could not exceed 90 degrees. Another guru said that if I look in the mouth of my plane there are all kinds of scratches from jam ups. A third guru said that Kato's numbers do not add up. Needless to say these people are lacking in experience.
