Interesting and nice to see all of the responses that have been posted since I made mines. I apologize if I came off as rude as that was not the intention. I just found it interesting especially after reading most of The Bowyer's Bible and one of the author's makes an excuse for using a bandsaw saying that you have to draw the line somewhere's and I thought his statement was pretty funny.
My own way of building primitive bow's might be seen as insane or very dogmatic by some people but I enjoy it as it forces me to think and work in a way that makes bow making feel more authentic, slow, and overall more rewarding for me. I use no electricity or anything that has a motor so no heatgun's, no chainsaw's, no band saw's and so on. I use tool's that have been used for thousand's of years like rasps, axes, hatchets, knives, scrapers, and stick to using natural glues like hide glue and pine pitch, and I use all natural finishes as well. I do the same with my arrow's as well.
While an argument can be made that the Indigenous people of America would of built bow's using whatever they had available, the whole point of building bow's in a traditional or primitive fashion is to take you back into time and do thing's as they were done for thousand's of years. So I have no doubt's that primitive people would of used band saw's, electric saw's, heat gun's, and so on, but that's not the way that they did it for thousand's of years so I don't do it that way.
If I had to build bow's using all modern electric power tool's it would kill the enjoyment of it for me and I'd just quit and stick to F word bow's.
Again, what's primitive and what's not primitive will change from the user. Same people will argue that a tiller tree is not primitive but I see no reason why this is the case considering that pulley's have been around for thousand's of years and a pulley can easily be made out of stone, wood, or metal. Bow's could of also of been tillered to a specific weight by hanging a stone with a specific weight from the string on a tillering tree.
