Those are awesome Pat. I love the use of natural materials, the way it was done for hundreds and hundreds of years.
I'm planning a build for 2018 where I'm only going to use materials that are found on my family's property. I have a dry elm stave that I cut 1.5 years ago, and these river cane shafts for arrows.
I guess I can get hide glue and sinew from any animals that I harvest this year (no pine trees)
The only parts I haven't figured out yet are the string and broadhead. We have muddy bayous, so there's no native rocks. I was thinking bone? And maybe make a string from palmetto stalks?
