What's the diameter of the holes in the angle iron?
I've just made my first "board" arrows, I shaved down 3/8" arrow staves to eight, then sixteen sides with a small block plane.
I did use the drill to sand them. I drilled a hole in a piece of scrap wood to check diameter. I' like the collar idea though, I'll try that on the next batch.
Has anyone else made arrows out of boards? what's your fav wood? I'm using oak now, have shot a few at cardboard, so far so good! I'm still new at this, this is a GREAT website by the way, thanks to everyone for sharing so much.
