pressure flaking patterns?

[iowabow]

I have been studying patterns in pressure flaking and thought I would share info and ask others to share what they have tried.  After you learn to make a point and pressure flake the next question is "what does this technique do?" So here is a photo (photo to be added after I charge my phone) of my point I worked on yesterday.  I ran a set of flakes then used the delta for the platform for the other side it created a snake like pattern on the edge that was very sharp. Then I pushed the deltas off to make straight. Notice the broken tip, I dropped it and hit the edge of a marble end table and broke the tip off and took a chip out of the table (Annette dosent know yet so don't tell her).

Ironically, I just re-read Waldorf and he states that oblique flaking is the best for persons wanting hunt with their points.

As for the table, deny deny deny

Mister, you are in a world of hurt about that table. Can you bribe your son to take the blame?

I might be able to spin it to the wall

Nice pattern on that one John! I've watched vids read books and tried some of that collateral, oblique, edge to edge, diagonal, progressive stuff, hahaha. hell, i don't even remember what half that stuff means anymore . Sure is nice when you pull it off though .

Well the search for flake patterns is continuing.   I read that I have to have a near perfect preform before I start and then I need to make a series of flakes evenly spaced out.  Well that is what I tried but the preform was not perfect so this is what happened.

yeow what Sparrow said :

You guys are too nice.  I came close on the right side but the left kinda got lost because the center was a little noisy and changed the direction of the flakes as they moved toward the center. I learned that when you start the pass on other edge but same side you need to be careful not to over shoot your flakes.

... you need to be careful not to over shoot your flakes.

LOL, you're worried about overshooting and messing up a beautiful flake pattern.  Last overshoot I messed up a point with took off a third of the opposite edge.   I guess it's all relative to where we are as knappers.   I'm loving the way you think through your knapping and show it to everybody in real time.  It is very helpful, even if sometimes it strikes me funny.

Keep on knapping! 

And, happy Easter.

I'd love to know what the heck you guys are talking about.  I'd like to clean up my points a bit but in the end my goal is 1) pointy 2)sharpish 3) not ugly.

Some of this lingo is like stepping into Nasa's control room and getting orders to do something which sounds exciting but you remember that you are only there to change the coffee filters out.

 I know this is a little obsessive but I want to try to control the pattern of flakes so that I can match them collateral or oblique or v them up or down. I figured the first step is to make a real good platform and create consistent flake removal. Once I have consistency then I should be able control direction.  Below is a new platform I am working on.

My goal now is to make sure all small high spot are gone without creating any hinges

Also up to this point all work has been percussion so I think I will move to pressure.  Those of you who are good at this please ring in if I am headed down a deadend. I am going to shape things up I hope in the process. I see from the photo that the tip is going to need to move to center.

By the way this is rock that Scott and I picked up at "Secret Creek"
