Hey, great work on the heads! Those are iron heads, right? What bits did you use and where did you get them?

Thanks! Yes, they are stock 360 iron heads. I borrowed cutting bits from a friend. A couple of different sizes and lengths. I also used sandpaper rolls. I could not find them in Sweden so I ordered from Summit.
