I thought I saw where you had a cut right down the center of the web soon to be your blade.
That must have been some trick to hollow out the crown like you have done. Were you able to simply bore a hole through it then cut away the rest, or did you have to grind all of the material out?
I think I remember you saying something about not having a forge yet or maybe that was someone else. Are you going to have to cut away at the sides of the crown to thin down the section that will be the eye? I really don't see any other way to do that,even with a forge a lot of material would need to be cut away anyway.
Interesting project and I know everyone is waiting on the outcome.
