I have an old woodie skewed Rebate plane that I use on occasion. It wasn't cutting right and I noticed a one eighth inch chip had come off the toe of the iron. I also noticed earlier that there was a small chip in the center of the iron, but I didn't sharpen it at the time since I could live with it.
I have ground the bevel on my water cooled Tormex, so I know that I did not over heat the iron when gringing the bevel. However, a previous owner may have over heated the iron and quenched it, thus making the blade too hard and easy to chip.
Before I go about grinding an eighth on an inch off the iron, would annealing it in a 400 degree oven for an hour or so, fix the problem? Thanks
