I am getting back into turning after many years. I have a set of Wards PowrKraft turning chisels I bought back in the late 70s - early 80s for using on my Shopsmith. I am guessing they are only carbon steel and not HSS. There are two gouges, one is 1" outside and the other 3/4" outside. Inside the flutes they are 1/8" less. What I want to know is whether the larger one can be re-ground to 45 degrees and used as a dedicated roughing gouge. I won't need this larger size for anything I can think of now and have already bought some middle price range HSS bowl and spindle tools to use on my Delta midi lathe.
