I have been knapping slabs of glass with both copper and antler pressure flakers. I keep running into a problem. I raise the edge near a face and prepare to flake. I abrade and notice the platforms...

I am having trouble visualizing what you are talking about >>> double ridge? A photo or two would help. WA

No photo at the moment. Picture looking at the edge of a piece. There's a diamond shaped platform on the edge with a ridge on the top face and a ridge on the bottom face. Both ridges meet on the same...

Take a look at the pinned topic above entitled "help with slabbed material". On the first page of that topic are a series of pictures walking through getting a slab from square edges through the first...

As far as I know it´s not mention in the "help with slabbed material" but what I do, is pressure flaking a small chip - "push in and down" of one of the riges and then turn it over and pressure flake...

Have you tried zig zagging? If you zig zag from both ends of an edge they meet somewhere and make a diamond but thats what i think of from what your describing. Or are you just pressure flaking the...

mowhawkwoodman: Thanks. I am zigzagging. I'm wondering if I'm not taking enough of the platform off and I'm leaving too much of a remnant. I'm going to try and press a little higher upon the platform...

it's very difficult to understand what problems you're experiencing from a verbal description. photos would be helpful in diagnosing issues. having said that, a lot of how you should approach knapping...

Thanks, Freeze cracked. Photos are not an option at the moment. I think much of my problem is just paying attention and focusing on what I'm doing. I did catch myself letting the piece move in my hand...

Do most people use some sort of support like a pad/rock? I've been doing it without any support.

not necessarily. when i knap just on leather, i tend to hold the work down near the bottom of my hand on the heel, which is i guess the most "raised" area of my hand. a major problem with knapping...

Thanks for the video suggestion and the advice.Very good information. I'll give it a try. I have snapped off a few (okay, most) points because of failure to properly support. Then there are the points...

As for dropping points, I started working over a soft floor mat and rarely break one by dropping it now. I dropped one that was almost finished today, and it is still whole. WA

When i leather knap i dont use anything under it. Thats one too many things in my palm other then the rock and leather. I like leather because i can feel the points and if im using toooooo much...

I've tried both, the ishi stick and the 6" pressure flaker. I really like the ishi stick. At first I thought it was because I could get more pressure but then I figured out that what it was doing was...

Freeze Cracked: I saw your comment about turning the edge was that the same as raising the edge? I do that and loose a lot of width as you stated. But I thought that without raising the edge you...
View ArticleRe: Pressure Flaking Problem
hi wayne - yes, turning the edge and raising it are the same. whether or not you remove the saw marks is actually a function of you properly controlling a number of variables, not just the position of...
