Tower, I hope it works out and y'all come on down here to the knap in.
Deerhunter, I point my flaker right in line with where I want the flake to go and apply a lot of pressure with my legs then pop the flake with a downward force. The platform needs to be below center and strong enough to support a lot of pressure before the flake is popped loose.
I will take some pics of platforms, flaker alignment, flake spacing and anything else that I can get a pic of that will help explain and answer your question. I just can't explainit.
Thanks Wally44. I already kilt a mastodon with it. Then I woke up and had to get ready to go to work
