That looks exactly like my bopper I made 3/4 inch cap, I did the same way melted the lead inside the cap after rounding it and use epoxy resin, but the head flew off eventually😂, then the next one I made I glued a wood screw perpendicular with the walls of the cap then I melted my solder and poured it in from a stainless steel ladle, then I use epoxy resin and screwed it on before the glue dried it has not flown off yet😁, I'll comment more later when I keep watching
@@miketufts9765 I believe it was the same material. It was mostly cortex. Patrick had a video awhile back he was knapping a big piece of chert and it had a whole separate pebble inside. It was crazy. I think he put it in the auction. Lol
