My first point

[lebhuntfish]

Well here it is, just like the title says, its my first point.  At least one that I didn't break.
I got the rock from Scott at mojam this year.  Im sorry but I have no idea what its called. 
I know that its not perfect, but im kinda proud of it. 
I would appreciate some critique because im trying to learn.  I do have a question though. 
I have a ton of plate milk glass.  It seems to knapp really well.  But the problem I have is that it pretty much all has 90 degree edges.  How do I go about angleing the edges so I can get the edge sharpened?
I have broken most of them except one.  (second pic)

Second point,  I put it on my trade arrow.

Good job Patrick. That first one looks pretty good. The second one looks like naviculite which to me is harder to get a nice scar pattern with.
For working glass and 90 degree angles. First lightly abrad flat 90 degree edge. Then I do what you call scissorsing the edge. I usually start in a corner. The abrading will help get a grip on the slippery glass and also get rid of lose weak material. Try to get a shorter flake off in corner, then flip piece over. Using the angled edge of your first flake try to make a second flake on opposite side of piece.Dont use middle of removed flake edge. Use side of it and lightly abrad it. Flip over and continue process. You should develop a zigzag edge. Once your all the way around you basically have a biface. I'm not sure how plate glass works, it might be a bit thin. I find anything I can practice with especially if it's free, has helped me tremendously.
Looking forward to seeing more

Thanks Bj,  I tried that this morning and it seems to work better.  I watched a video last night where a guy was showing how ishi was making his last point before he died.  It was a piece of plate glass worked in the way you discribed. 
The glass I have is called milk glass,  it was in 4 foot sheets and was used for shelving in my grandma's feamarket.

lebhuntfish, nice first point, I like. On your milk glass( sg edge) materials stitch your edge with short flakes , move edge to one side and next pass longer flakes to start building convexity, flakes don't want to travel far on a flat surface. Bob

Nothing wrong with those, Patrick. That first point is Georgetown. You did good.

Thanks Eddie,  Ive managed to get about a 15 points made in the last few days.  Ive pretty much just tried to make whatever I could out of what I had.  But its been fun and educational.

Glad to here your still chipping Patrick. It seems like you have the right aditude. If you can just keep from getting frustrated it can be very relaxing and amazing how fast time goes by. Warning, just like bow building this can become very addictive. You will find yourself looking at landscape rock, glass bottles even old TV's and computer monitors. It's ok, it's  :-Ktotally natural. All of these objects want to be made into something created by you.

PS that was good advice from Outbackbob, I wanted to tell you the same thing but didn't have the time at the time. Many big and little things to learn. Always pushing your comfort zone to expand you limits. Also breaking a lot of nice points along the way.

Looks real good!  Hang on to that and watch how you progress!  I am about ready to start on my cache of stone and plate glass, I think.  Put a big split in my left thumb right at the contact gripping area though!  Puts me back on the sick, lame, and lazy list!  Guess I will just play and work through the pain!  Still have to finish the batch of arrows, layout the hickory stave, make a couple new strings, figure out how to operate the "tin tipi"' organize the garage so I have room to work, etc. then I can start knapping, not to mention hunting, shooting, practicing, and the ever present "Honey do list"!
Good job, those Eagle Scout skills pay off now and then!

Thanks Hawk!
You sound just like me with all of the "to do's"!
But as of now I don't have any thumb injuries, just sore shoulders and neck.  But life goes on!
