Re: Replacement cap irons or chipbreakers!!!

Warren in Lancaster, PA
When the "improved chipbreaker" came out I took it as evidence that the Lie Nielsen
people had no idea how to use a double iron plane. However some wondered if they were not made deliberately ineffective so as to sell more high angle planes. I give them the benefit of the doubt.

I have used a rounded "bevel" on my cap irons for over forty years. As Nicholson says 205 years ago "The bevel should be rounded and not flat." A low flat bevel just will not be as effective. It is difficult to estimate the actual angle where the cap meets the iron, but let's just say it is closer to 80 than to 50 degrees. A 45 degree flat bevel gives a weak action.
