[TheForge] Cone Question

[Dan Scheid]

I had a cone mandrill  turn out from my local machine shop. for a cone shape
collar used on spear tips best money I spent . take pie shape steel, heat
up, wrap around mandrill in hardy hole , weld, clean up done.
my cones are 1" in diameter and about 4" long taper to a point about 1/4" in
diameter
