I have a question about these tools that I have built. I hope cwi555 will chime in here and provide some of his metallurgy background for answers, or any of the other members as well!
I am using copper, obviously, for the flakers and the ends of the boppers. I am "work hardening" these by hammering them into shape. The flakers are hardened by hammering into a point and the boppers get hardened when I shape them into a sphere (they start out as a normal pipe cap, kinda square shaped)
A question I have is, I pour molten lead into the bopper ends before I epoxy them onto the handles for weight and greater impact. Does that anneal the copper material back to its softer state? And if it does, would my continual use of the tool by striking the work material repeatedly continue to work harden the copper tool end?
Another is (sorry to ramble) if the hot lead does anneal the copper could I temper it while it is still heated by the molten lead? Say maybe pour in the lead and then go straight to an oil dunk?

We are not rushing you man, make the video when you feel ready. But don't worry about the mistakes or something not working just explain that that is what is happening and has happened.
We are going to experience those times when we try to follow your video and seeing that they happened to you will let us know we are close but off and you had the same situations.
And a video where it doesn't work can be just as good of a learning tool as when it does.
Don't edit out the mistakes, when you figure out what was wrong then use the mistake to show the correction.
Someone asked about KY both my Daughters live in KY and I lived and worked there 10 years what do you need from KY?

Someone asked about KY both my Daughters live in KY and I lived and worked there 10 years what do you need from KY? The video is coming. I'm having a few 'real world' problems at moment, vehicles not cooperating and a wiring problem in my house! Trust me there will be plenty of mistakes for us all to learn on in the video! I do plan to leave it like it is filmed, just like the few others I have made. I think it is just as educational to watch what someone does wrong as it is to witness success. As a sidenote to that. When I was racing as a crew member we would spend any free time we had reviewing replays of any wrecks or missteps by the drivers trying to analyze exactly what caused this or that for the driver to lose control. A smashed car that just hit the wall at 180+MPH can provide a fabricator/mechanic with a world of data. If you are at a track and see a crashed car pulled behind the wall it will not be very long before a whole crowd of racers will be gathered to not ewww and ahhh but to see what broke first. But enough of that! The deal about KY is redneckidokie saw a fella selling a type of flint stone that is known as Kentucky Blue. It looks really nice, I have never seen any of it and don't even know if it is actually from there or that is just the name of it because of it's color. I just need to fix some of this chit so I can get back to playin!!!   |

Melt temp for lead is 622F. The lowest annealing temp for Any copper is 900fF.
I seriously doubt the lead will anneal the copper.

I trust what you say more than anything my Google machine tells me. I do find it pretty cool how hard the copper becomes with the work hardening. I knew some of this but it really makes a significant difference with my little copper pieces. |

Very well done!! I am looking forward to seeing what you do with the tv glass! Are you going to make the shafts for the points as well? If you make a spear point, are you going to try using an atlatl with it? That is my long range goal. I've made my long bow from Osage and the sting for it. The bowsheath/cover and my quiver are made from deer hides I killed. I've made the turkey feather fletching from turkeys I've killed. That leaves me with making the arrowheads and then the shafts. After that comes the ultimate challenge....harvest a deer with the whole set-up! Once I do that, even if it the smallest doe I've ever taken THAT deer will be my greatest trophy and I will mount it myself and proudly display it on wall. I don't intend to build a spear, or at least not yet! And I know nothing about those Atlatl things. |
