Get that flat spot out of the left limb (about a third of the way in from the tip) and she'll come right around. Sweet arc for such a shorty.

That's a lot of bend Pat. I'm hoping she stays together too ;)

You just had to jinx her didn't you Cipriano.  ;)

Well, I was exercising her before removing some more weight when she went BOOM! She was on the tiller tree and I was pulling her to 20" to see where I needed to remove more wood to get the weight down when she went. I have to say I'm not all that surprised, disappointed yes but not surprised.  :(
 Anyway, I will remove the sinew and and do a post mortum to see if I can figure out what went wrong, other than trying to get too much pull for her length.








NEXT!!! ;D

Nooo! I just saw this thread for the first time since that bow went a way to dry.  My heart dropped too, when I scrolled down to the pic.  I am sorry pat.  :'(

After thinking about it for a while and then studying the break I think she broke in tension, ripping the sinew when it went. I made sure when I layed the sinew to cover the handle, fades and out to the limb well because that is where a lot of the stress is. The break initiated(from what I can tell)at the crown on the bottom limb about 5 1/4" from the center of the bow which puts it 3 1/2" from the handle. This bow was to bend in the handle at full draw so I left the handle area a little thicker. I should not have done that! It only concentrated those stresses to a smaller area and the bow gave where the limbs were fading into the handle, side to side and back to belly. I created a weak spot right at the fades. Looking at the last pic I posted of the bow drawn at 24" the left limb is the one that broke in the third pic and the right in the forth. It looks stiff right off the handle and and it probably hinged right there causing the back to fail.
 The bow was at 20" when she blew. I was exercising her after doing a little weight reduction scraping on the belly. I had also thinned(belly side only) one side of the fade on the failed limb side but all I did was rasp then scrape a little to shape the fade more evenly. I guess that also might have "given" just a little more and in wood bows, "just a little more" can be deadly!  :(
  I'm sad this bow went. It was my shortest so far and I was pushing her to see how far she would go. I will do different next time.    ...and thank goodness for the tiller tree. I don't even want to think about if I were holding it in my hand or working with a tiller stick.

Bummer Pat. I feel your pain. You had that baby looking really good. As you said she was definitely a shorty. I think your analysis is probably right on.. On them shorties that bend through the handle is critical.  On a good note I know where you can get some more, Pushing the limits is how we learn the thresholds

Making a bow bend through a narrow transition like that is tricky business - especially with those big paddles further out. I've not attempted that design for that reason - you are braver than I am.

Keenan, I'm totally blown away how little wood she had in her and she was pulling in the mid 50s @24".
  I've already been thinking about the next one. Some of the sinew on this bow was recovered from Elkie when she kept rejecting it. I soaked it off and saved it. I will do the same with this sinew. Maybe the third time will be the charm.  ;)  I'll call the next one "Patches".  ;D

  I think I'll make an atlatl out of the remaining handle and good limb. I've never made one of them before!  ;D

Ignorance is bliss, Gordon.  ;) I realized that about bending through a narrowing section was a no no...after I examined the break.  ::)     Hopefully I learned from my mistake.
