Title: working the biface
Post by: iowabow on June 11, 2011, 12:32:45 pm
Thought I would share a cool thing that worked.  Maybe this made no difference but here is what I tried; I prepared the platformas normal and then thought I would abraid the top where there was a small step with a little junk. I did this to bring the rear rigde and the forward ridge together.

x2. knock that mass down a little and it'll come right off of there with the right platform set up just right.

This knapping thing is fun.  Something new to learn everyday.  I did not come up with the idea I think I read a post when I first got on here about someone doing it.  It sat in my brain until today.  I remember some one said " you grind the ridge? He said yes" I thought that was very odd until today. If you are trying to make the ridges match/join it makes sense.

Good technique to keep in mind.  Thanks for sharing.

I have encountered more problems. The stone has concret frost like flakes that are causing a lot of problems so I used a punch to remove a stack that I could not get from three directions.  The next 2 images are of the nice side and the bad side.

The last photo of the bad side, Id bring that platform flush with that side of the face and work the "top side" down to get ride of that coarse looking area, then on the dip just below that, Id set up a platform on the bottom, on that protrusion. Id take the ridge off just to the right of that to allow for easier flake removal, then hit the platform on set up on that protrusion and try to drive it sort of up and right in the photo and see if you can get under what looks like a cliff edge in the dip....

But dont take my word for it. You're doing better than I am lol. I'd probably miss the platforms and mess it up worse. lol

These "problem" series threads ae fun.

Ok good ideas.  Next post I will draw out the plan on the stone. But understand it is not set in stone!  I could not resist.

Looks like you got that under control. What I want to know is what kinda rock is that? I LOVE the looks of it!

Not sure what it is called.  It is some of the flint that leapingbare sent in the spring.  I have included a picture of the plan but it may shift a little to the left.  I was trying to get ever mm from this small stone.

Working real hard to make sure platforms are just right before I swing.  I was able to remove the step on the good side and working very carefully on the other side not to upset the dragon in the middle.  The shape is coming around and the blade is getting thin. I would been very happy with this in Jan. Of this year but now I know there is more to be done.

I worked more on the difficult side and almost finished the straightening. One more side to go. I get real nervous toward the end and try to take no chances at this point. I have put off working on the point because I seem to alway break it so this time I am going to wait till I am almost done. I will probable finish the point before the base. I have only been knapping 6 months so I don't have as much skill in the finishing of the point. I was thinking of doing a side notch, any thoughts guys?

Post by: stickbender on June 14, 2011, 06:26:18 pm

     Yeah, I have thoughts! >:(  Why the heck did you have to mention you have only been knapping for six months!  I can't do that well, and I have been attempting to knapp for far too long to only be where I am at.  I guess we have another smarty pants on board now!  Maybe I can see about a room in the Bulgarian monastery for you also! ;D  Nice job on a tough piece of rock! 8) I am only working with Obsidian at the moment, I have some tough tough stuff Mullet gave me, but I can't work it yet, at least not raw.  So I am going to save that till I get somewhat better than I am with the Obsidian.  But it seems that you are light years ahead of me.
Now I want to see how you notch it, if you do.  I can't notch worth a darn. :(

That was a funny post! I am also not great at notching but hope I get a chance to on this one.  Well here is the pic of the almost completed side and if you look close you can see the pencil line on the other side. I will have to fix the base but I learned a lot on this point so if it breaks it is ok because it is the journey not the distination that I enjoy.

I haven't been posting here long ,but I've seen you come a long way in a short time! Practice,practice,practice. Centerline, platform,abrasion. In my opinion go for broke. It's the only way you get better. Notch it from the edges in! The same principals apply in a notch that apply on the edges. I'm not an expert but I did stay in a Holiday Inn Express once!

P.S. Justin too . Very good knappers the both of them! I my opinion.

Things went real smooth this morning and the other side is done.  I have one coner that is rounded because there was just no material there so I was thinking of matching the other side.   So what do you think guys corner notch or side notch ? I thought that I would side notch but not sure.

I'd probly give it some side notches. Looks good! ;)

It takes me a long time to finish points with so many other times going on. Anyway here is the finished product.  Comments welcome.  I like the point but I would have done it differently knowing what I now know. I think if I had rounded the sides the edges would be sharper. I had nice angles before I shaped it all.

hey cowboy thanks! you know this site is a gold mine of information. I have said it many times before but you all really helped me out. Without this site I would not have picked up on this for years. I have wanted to knap for 20 years and just did not have the instruction available to make it happen. I am going to TN in a couple of week and cant wait to see the pros working the final stages of a point. I really want to learn how to do good finishing work. Are you going?
Title: Re: working the biface
