For many years I have had a scrub plane with a 1/4" A2 iron that is awesome. However, I have been trying to streamline the volume of tools in my shop and have chosen the scrub as a target for elimination as I believe I can get acceptable results with my jack. I have always ground my jack iron (#5 sized Millers Falls) with eased corners so that I could use it for cleanup tasks, jointing smaller objects, etc. but if I am going to use it for stock reduction I believe a full camber to the blade would be helpful. I further believe this will complicate the use of the jack as a small jointer or a plane to prep flat stock. With this in mind I have two questions; when I camber the iron, how far back do I set the chip breaker (the scrub has no chip breaker) or is it irrelevant for the rough work but negatively affects the use of the plane for jointing? Also, would it be better to replace the scrub, jack, and fore plane with the Veritas BU jack with a variety of irons as it is very easy/quick to replace the iron? What are your thoughts?
