Flake Spacing

<< < (2/2)

Jodocus:
Thanks guys. From this I take that I'm doing it right and there's no need to try to be overly regular in pattern.

Stringman:
Like Patrick said, certain point types did demonstrate precise flaking patterns. If you aren't trying to replicate those styles, then random is fine.

When I am making side notched hunting heads I tend to setup running platforms and try to keep flakes consistent so I can match grain weight easier. As has already been mentioned, he distance between flakes changes with regard to the size of the point, the way you're removing them and the size of your flaker. Percussion flakes can be up to an inch apart, while final pass edge flakes can be 1/8" apart.

Or another way to think about it... On an even surface that is mostly without problems, the flake you just ran should leave a ridge that your next flake should run under. This process will carry all the way down your point. Or at least, that's the theory.  ::)

Knapper:
Great thread and good comments and ideas we novice need to think about. I know when we look at the points being made on here we strive for symmetry and good straight lines. Patrick, I didn't know you made mistakes, your points are top shelf! But yes good flake scars seem to be a sign of mastery of the art. Hopefully some day I too can get this down. As many have said "Its all about tonnage "

Dalton Knapper:
I typically do it one of two ways, one I learned from Jim Winn (he has a video somewher on YouTube on this). Of course to start any method you random flake where necessary to get good convexity and a smooth point. What Jim does is to take a flake, which winds up thin at the point where it was removed and widens out as it travels. What he does is to take two to three small flakes that straighten up the lines on that last flake scar so that you get a straighter ridge for the next flake to follow, and so on as you move down the point. He straightens up the curve in the flake with these smaller flakes at the "delta." And you proceed a quarter inch or more down the point like this depending on how big your flake scars are to begin with. Of course don't forget to bevel and grind and work below center before you start the flaking process.

Conversely, it works pretty good on some materials to just skip your flakes a quarter inch or more apart down the point and go back up and clean the deltas (the area between flake scars) out afterwards.

I do either or - not really convinced one is better than the other and it makes a nice pattern if a pattern is what you are after. Of course it is more random than FOG no matter what - as already mentioned.

Zuma:
Very cool thread. Thanks for starting it Jodocus.
Nice to be here sharing the awesome info you all provide.
I started with pretty crappy materials. Most of which are never
abo knapped with any pattern but random.
My concentration was on wide, long and fluted blades.
Hard to pressure flake across well.
I have not put to much time and effort into patterned flaking
until recently. Now I can get material that may allow me to
knapp it with some foreseeable outcome.  I am sure the materials
will make the difference as well as all the neat info right here.
