What is the correct crowning tool to do the crown? I have seen some on brownells but I wanted to make sure that I am getting the correct one. If everyone knows please let me know. Thank you
Most grind their own tooling to some degree with relief and angle to suit. I use a brazed on tip tool for crowning ground to a certain angle. HSS works just as well. A lathe with a four jaw and spider works best.
