Papa Matt, go to your hardware store, and get number 4, or 8 copper wire. They have it on spools. You can buy it by the foot.
Also go to your plumbing supply, and get your different sized round end caps, for your copper boppers. Not expensive at all to make a bopper, and a couple of pressure flakers. Make one with a long handle, about two ft. or so, so you can use your knees, and arms together for the pressure. The short handled ones, you can make for finer details, and such. I too just started, and have given a lot of blood to the Gods of the Lithic realm, just last night I was up till 5:30 am. and went back out in my garage, and messed around with a flake, and was experimenting, and got a nice blood blister on the pad of my left ring finger. I have started to get some nice flakes, but I am not consistent yet. Still light years away from doing stuff, like Jesse, and Claude Van Order. I did make a decent one out of untreated Chert, but it has a lot of inclusions and hair line frictures in it, so I thought I would leave well enough alone. I had one out of Obsidian, but I had it in my welders apron, and it broke, and I couldn't find the piece to glue in to show it. So I just tossed it. Just read all you can and watch the U-Tube videos, and practice on what you have, and if you make a nice flake, remember how you did it, and try to repeat it, and learn from your mistakes. Just get a flake, and practice making long flakes, and then practice notches, and when you can do that pretty well go for the full Arrow head. It is all an oops, and ahh, process. Sometimes, like with me there is an occaisional #@$% ! moment, like when I had a nice point thinning down, and it decided to break, because I did not have it supported. I started to get resullts, and I got in a hurry. Take your time, and abrade, abrade. I may try to post a picture of the Chert head .
