EGADS SIR! Video 001 and it is about indirect pressure flaking! Seriously just TODAY I made my first steel indirect flaker and with the wonderous KELLY STRAP I managed quite a few okay newbie flakes. Feeling cocky, I tried my short pressure flaker, of course snapped it. SO much to learn and at 73yo I am willing to give it a go.
Yup, I am the one who invented the "behind the knee" technique 14 years ago when everyone was stuck in a rut using techniques from the 70's and 80's. 😊
really cool technique! I can pressure flake just fine but this technique works so well on smaller points that are hard to hold in the hand without snapping them in half. I use more of a continuous platform as in pressure flaking and the results are amazing I have made the most thinnest points ever using this technique! thanks so much for sharing the videos they all are very enjoyable and helpful.
Hmmm... I don't know either. I don't have the book. The only thing I can thing of is the technique of lightly tapping the edge to get rid of the sharpness and strengthen the edge. It is done as an alternative to abrading. I demonstrate the technique in my video "1/2 Spalling Chert (Flint) for Flintknapping".
I always wanted to know how they made arrowheads. You make it look easy. I must say tho, your fingers take a beating doing it. Your left hand is plum ate up.
Is that Hornstone? I just bought several pounds of it at your advice. Or to say you had expressed a liken to Hornstone. Can't wait to get it. And I do believe you are an expert. That's just a matter of opinion. But I believe you have achieved that level.
Hey Jack - love your stuff. I've never been able to get the hang of indirect, but come back and watch this video regularly trying to figure it out. Something I can't really tell from this video - how hard are you pressing into the rock with the tip of the flaker before you swing (or are you just setting the tip on top of a platform?). Relatedly, how heavy does your moose billet need to be when working with pieces this size? I've tried using my delrin ishi stick pressure flaker for indirect with a heavy bopper in place of the billet, and I can't seem to get flakes to detach unless I swing REALLY hard, which it doesn't look like you are doing here. Any suggestions?
I do swing REALLY hard. But you tool tip might be loose or the delrin too flexible. Try making a stiffer percussion tool with harder plastic and thicker copper rod.
Yes, I put my foot on a block to elevate my knee. I cradle the flaker behind my knee. You can see a front view of my knapping if you search for "Jack Crafty front view flintknapping"
You stated you developed your indirect percussion technique just by trial and error. I have the same problem of not creating a flake that travels across the width of a piece I am working on. This technique seems to alleviate the short flake syndrome. I also see people using a thick piece of rubber with a gouge or groove cut out in the middle to allow for a wider flake to travel. This might be an alternative too? Its all about trial and error. :)
Yeah, it could be a little sharper but I let the diameter of the wire determine the sharpness. It's kind of like using a mechanical pencil vs a pencil that needs to be sharpened.
you should bevel to your flat clean side first to raise your platform edges before you take anything from the cortex side. Otherwise you make it much harder by making the dome higher
This is my very first video! (so I was not very experienced) And besides, I like working with thick preforms. I was not trying to thin the point in the beginning.

Welcome to the addiction. Haha. 😆

It all began here
Yes
look how happy Jack was before every video became him responding to trolls and autistic know it all's who dominate the hobby!
Awesome! I'm always very glad to hear about positive experience with this technique.

Very ingenious techniques.
thanks. I'm glad this old vid is still attracting attention... :-)
You're welcome. Glad you found the videos useful!
your indirect pressure flaking looks like a workable techniques to me and far easier than counting on a perfect eye and hand contact..

@rshotrod1965 Yeah, the fingers get messed up. I'll have to make some leather "finger socks" or something. They get really bad in the winter.

This is chert, in this video.
Hey Jack, what diameter Delrin Rod are you using in indirect??
The diameter is about 1-1/4" but it's metric so it's a little off.
I've used several diameters over the years. Mostly, I use 1-1/4" but I've used up to 1-1/2" and as small as 3/4" diameter.

is your foot on a block? Do you cradle the pressure flaker under your knee and leg or against chair seat?
Yes, I put my foot on a block to elevate my knee. I cradle the flaker behind my knee. You can see a front view of my knapping if you search for "Jack Crafty front view flintknapping"
@@KnapperJackCrafty Thank you very much! I really appreciate your videos.
1 Jack you dont need sound o=your videos are great. 2 wheen i orded texas flint mine looked so driffrent cortex was the same but not the inside
Thanks. Yeah, Texas flint is very unpredictable unless you gather it yourself. There are many different colors and variations.

would you do a video from the other direction. shooting towards you so I can see a better view of your style of indirect percussion.
See my video here: th-cam.com/video/capGa8Mr-mU/w-d-xo.html
Cool technique I just started knapping myself if I have any troubles I will give this a try for sure , thanks for sharing .
Thanks! Glad you found this helpful. :-)
Shouldn't your flaker be sharper? I am just wondering. I somehow think it would make things easier but I might be wrong.

I can’t wait to try this technique! Thanks a ton!
You're very welcome.
