Fellows thanks for the help. Funny that in my stage of making arrows that I have never tried to grind the feathers flat. Back in the old days (50s) when I was learning to hunt with a bow there was Herter's and you could buy about anything for hunting, fishing, or trapping. I bought feathers from them. We had no turkeys and goose wings were about all that was available. I do have lots of feathers and a large belt sander, just no straight clamp. I laugh at the arrows I used to hunt with. No two ever alike with some of the ugliest points ever imagined. Killed just about everything we had to hunt except an antelope with them. Used to just tie the feathers on with fishing line and when they came off just tied on another one! Am planning a Texas hog, deer, and turkey hunt with Hawk Huston in Oct. so getting ready. Still to warm to hunt elk here at hope but have all those arrows ready. Pat some day you need to come to Wyo. and hunt with Hawk. A/Ho Joe
