How about posting a pic of how that jig actually works?  I am not visualizing the pressure points at all!
Nice work!

Zero experience at fluting and almost none at all with knapping after the summer of 1989 when I was playing around with it. Mostly commenting so that this will pop whenever someone comments further.

That is an incredible flute, running the length of the stone!  It makes me wonder what the ratio of the loss of mass to the loss of strength/durability would be, seeing as how it retains the two rigid ridges just inside of the cutting edges.  And also what the comparison would be in penetration before and after fluting.  I am sure there are certain advantages in function, even though just plain old bragging rights for sheer cool factor and prettiness and difficulty of execution had to have a little of the spotlight.
Guns have triggers. Bicycles have wheels. Trees and bows have wooden limbs.

1442, thanks again . You have  answered and cleared up a couple issues that I have had with my own fluting. When you say you tap your bit are you actually taping your bit or just pushing outwards with your other hand upon the release of the platform?

I'm actually tapping it with a hammerstone about the size of a base ball or a 1" bopper.
When the flutes release before I get max pressure built that I want to put on it,  they always turn out narrow and short.

I think some of the advantages of a long fluted point would be a thinner haft and the profile of the tip area with the channel of the flute scar is just built for penetration. The Cumberland people who where making these long fluted points where hunting mastodon, so they where having to poke through some really thick hide and meat.
Then later in time the shorten thinner Folsom points with full length flutes evolved to hunt bison.

Hawkdancer, I'll get a pic of a diagram of a solberger jig and post it. There are other types of fluting jigs too.

Here's some pics of a few more fluted points
This first one is made from raw landscape gravel and shows a good edge view of the tip profile when the flutes go all the way to the tip

Very nice ,thanks Bob for bring this up. I see yet another project in my future. I'm building a brick oven now but hopefully making some flint knives soon.

nice flutes zuma
I always had heck trying to flute points prior to using the jig but I know now I was not setting up the platforms properly at all.
Thanks Hawkdancer,
I been gonna make a drawing of how the jig works to apply pressure for you and to show a couple more details that I cant explain without a picture.
got a few things I need to do for Christmas first though.
