Well, I turned a perfectly good obsidian preform until a teeny 68 gr point this morning working on my trade points for Fred. Good grief.
Really a shame and totally my fault as I tried to thin too far out on the tip with indirect. I actually broke the point off the point (
been dying to type that) 3 times before I was done.
Then I tried a bottle bottom and first broke the bottom perfectly in half (which I liked). Then I was able to break each half in half again (didn't like that so much).
Think I'll quit for awhile.
