How Chipping of Edges Happens at a Microscopic Level

Larrin,
Bless you.
You do this just to determine if there is anyone left here who has two brain cells who know each other . . . is that right ?
I woke up to THIS !
No coffee yet . . . it isn't fair !
It's FUN but it isn't fair and I have coffee brewing as we speak. It is a good thing I had two good nights sleep or I would have just stayed in bed and whimpered.

Ah well at the very least you have provided me with a simply fabulous quote for my "signature" below and for that I thank you.
Fracture Lubenics. . . they measure the fracture toughness of watermelon, because science is important:

I'm by no means "educated" or a scientist. Using my motto bellow, however, I was able to finally decipher a formula that I can use to calculate the spoke length for bicycle wheels within less than half a millimeter, every time, simply by measuring the components and running the formula. It even takes into account the elasticity of the spokes and the compression of the rim taking into account the crossectional profile of the rim (did I get the terms right?).

I was working with custom bicycle makers way back then building wheels that had never been built with components that had never been built (to those dimensions) before. Think Answer Forks ala Manitou Mountain Bikes . . . owned by Doug Bradbury. Those were the good O' days !
So you see I do have faith . . . faith in the repeatablily of scientific method.

. . . anyway . . . GULP, GULPCOUGH . . . I'm slamming the coffee as I type . . .
I'll get back to you . . .
Thank you for the fun though challenging info ! ! !
and now for my motto in dealing with such papers as yours :

One thing I took away from this article, is that in using these steels for chopping tasks, the edge geometry must be made appropriate to the task.
Thanks again Larrin!:thumbsup:
 
Hearing that my articles are hard to decipher is nothing new. It just means I’m a poor science communicator. Maybe if I keep practicing.
 
Try not to say his name 3 times or he'll show up 444 times, and this whole thing will get a helluva lot more confusing.

All I knew before this and all I still know is that I keep my machetes a bit blunt so they don't chip as bad or as easily when I hit rocks and stuff.

Now you’re just trolling.

I was just making a dumb joke, but it is true that he'll probably show up as this exact subject is what he lives for.

Now I honestly didn't get much from this article and videos, i just couldnt really follow it well.
all I learned is that keeping my machetes slightly blunt is a smart thing to do.

Not in the least !
I'll have none of that.
I was just saying . . .
I'm not awake . . . still . . . and I hope to be . . .

Who is he?

We don't say his name, but you'll know if he arrives.
This is the exact kind of thing he's always arguing about, micro rolling and micro chipping calling his cheap 420j Rambo replicas better than some kind of high end steel.

You know what I'm sorry I even brought it up at all, I started something and " he " is probably not even logged in.

Larrin, the subject matter is heady, so many of us struggle understanding it, but the delivery is just fine.

Thanks, I appreciate constructive criticism as well as reassurance. I just have a strong drive to make the articles as good as possible. The current one may have had too much math up front to glaze eyes over.
 
Larrin, I'd be interested in your thoughts about stress risers, especially at plunge lines where they can become a stress riser, and whether sharpening choils centered in the plunge line can block stress lines, but also with thumb holes, thumb studs, jimping and even saw teeth on the spine.

I am also interested in stress risers forming along coarse edges. On my choppers, I usually go with a coarse edge, mostly because it's going to get dull fast anyway so time spent on a refined edge is wasted. But from your essay, it would seem that choppers would have stronger edges if sharpened all the way through the finer grits.

Thanks for your post.
 
good stuff. thanks for doing it and sharing it with us.
