vertical grain is stronger than horizontal grain

bump it up to about 50 ish,, and it will tell you a bit more about the wood,,

The scope of the experiment was, to see if the splitting surface holds up as a back. Even mostly unscraped and with imperfections.
 My thinking is, the back would have failed before the belly, when overstressed, if the imperfections would have done too much harm. And that is supported by what you say: the wood is always more tension strong, but the sides would have changed, if using the raw splitting surface, changes the tensile strenght properties.
But exactly that isn‘t the case, the belly failed and which shows, that the back is still stronger than the belly.

In short: I wasn’t about to show if vertical grain is stronger. I guess you haven’t read all of my posts.

@brad:
Do you mean the one I showed in my last post or when I redo the experiment?

Silly me, I was fooled by the title and all the earlier posts that talked about that subject.

when you experiment,, I think the heavier bow will give you a better represetaion of what the wood can or can not do,,

[Artus]

That’s the plan for the next try

What do you think about the bow I showed recently?

[willie]

you might try shortening this one actually. the tips are not really working anyway, you might want to make the right limb bend as much as the left

Thanks Willie!
But I actually decided to discard this one and take it as a practice piece in primitive bow making. I harvested another ash recently. And now I think I got the hang of it on how to make a bow with more primitive tools. I learned the approach is slightly different than doing it on a workbench with a draw knife, but it works just fine. I just need to get acommodated to it.
