Axe maul handles

cityofthesouth you're taking all this to heart! It's immensely useful to dissect and discuss the cause of wood failure.
I came across a "dead" 5 lb Mastercraft construction axe in a highway contractor's waste bin last week. The factory installed handle had broken so the tool was likely abandoned and then some time later discarded. It is painfully obvious that severe grain runout, virtually identical to that of the handle shot I post every now and again, contributed to this break. However when you inspect a side view of the same piece of wood you can also see the detrimental effect of weathering and shrinkage. This axe did not see light use (as evidenced by the poll mushrooming) and IMO it's quite impressive that the flawed grain hickory held up as long as it did.

Your last reply leads me to believe that you think run out and "grain" mean something different than do I. I'll just leave it at that.
 
You guys have to be kidding me and I'm just not in on the joke. . .
No kidding and so no joke.



. . .Yes, wood sawn at an angle, how specific do we need to get?. . .
At least specific enough to know what you are talking about that's being sawn at an angle.



. . . EVERYONE GETS IT!. . .
Do you mean everyone on the planet? Gets what?



. . .Half of your words are exactly the same words I used. . .
Well then, you are half way there.:thumbup:



. . .Can we get past the semantics at some point?. . .
Which semantics? Someone call a screwdriver an axe? They are both tools.



. . .This handle did not break "exactly the way a run out handle breaks". The break LOOKS the same (because it is a long straight break). . .
If it looks the same, then how do you know? Mystical powers? Looks like it separated along the grain to me. Look at FourtyTwoBlades' video in post #4. Did this one break across the grain?

. . . but is exactly the opposite orientation to the grain that it should have broken IF it did in fact break due to runout. . .
Does exact opposite orientation mean perpendicular?



. . .Bob, your new picture perfectly illustrates runout. . .
Thank you.

The red line illustrates how the OP's handle broke and the board in the picture also perfectly illustrates the OP's handle grain orientation. . .
How do you know this? In the OPs handle, what is the grain direction in relation to the head? The OPs handle looks like it was made out of a board like fig 2 or 3 to me.


. . .Bob, my point is this with "across"; just because it is not 90 degrees perpendicular does that make it no longer "across"? I am using the term across because while it is not 90 degrees perpendicular (it's far more acute or obtuse I guess, depending on how you look at it). . .
From post #41:
The OP's end grain picture clearly illustrates that the break is perpendicular to the grain - that is, across. . .
So is it perpendicular or not? As long as the long grain fibers are broken it would be called across the grain regardless of the angle.



. . .Now, please take a look at your own pictures. This one indicates runout exactly as we all understand it. . .
Figs 2 & 3 both illustrate runout. Not sure about the "we" part.



. . .You will note that it is completely contradictory to your image from page one and everything that guy says in the link. How is it contradictory? Because the picture from page one illustrates quarter sawn lumber. . .
I assume you are using the terms flat, rift, and quarter sawn as the grain orientation in a board (not some term a sawyer might use for how he/she cuts a log). Like this:

. . .with a pink line running at an angle on the face of the grain. . .
Board grain has three surfaces runout aside. Face grain refers to the surface along the width and length, edge grain thickness and length, and end grain the ends of the board. Just to clarify the pink line is running on the edge and not the face.



. . .This handle, and the image above all illustrate flat sawn wood and unless I am still missing out on the joke. . .
You may be missing the fact that flat, rift, and quarter sawn boards can all have runout. You are not missing a joke.



. . .runout breaks occur WITH the grain. [However, that guy is specifically talking about what is exactly illustrated with the pink line in the picture from page one. And he is consistent is calling that runout. He even demonstrates it.
Repeated from above:

Tried replying last night and was getting server errors too.

All I can say is that I think you are reading far more into "runout" than is usual - the way I've always heard the term used, it is just the grain running out of the sawn face. I've never heard a distinction made based on whether its running out of a quarter sawn face, flat sawn face, or any rift sawn face.
 
"Ultimately the point is, the "on the face" type of runout can't be terribly important because if it were, we'd break a lot more handles" This is EXACTLY the reason why vertical grain orientation is best. This applies to straight and curved handles, although, straight handles tend to have less problems than curved.
 
. . . My point earlier was, this type of runout would happen on curved handles no matter what. . .
Correct me if I am wrong, but I don't see mention of curved handles in your earlier posts. Assuming I missed that, the OPs handle is a maul handle (relatively straight) and we are discussing handle seperation across the grain vs with the grain, so I don't see the relevance.

Where did the description "on the face type of runout" come from for an axe handle? Are you kidding me? I never heard that an axe handle had a face. That terminology has got to be made up.

Well, being open minded, I went looking, and low and behold I found it! I guess I'll have to manup and admit I was mistaken because here is an example:
