Ash longbow - 45# at 28"

[FilipT]

Another crack thread. 

I started today ash longbow and removed a lot of wood using perpendicular cuts to layout and then chopping chunks of wood of. Probably the best technique for fast wood removal but lo and behold, hidden knot took the split inside the layout (back).
I filled the crack with CA glue and clamped it. Was this a good thing or I could expect further problems? Should I maybe instead try to get rid of crack by going around that place? You can see that I have enough wood on the other side.

If its in the handle or fade or tips you may be ok. Otherwise, back it, or sinew wrap it, but sinew wrap is hard to do and tiller a bow so....

[FilipT]

That is a bend through handle longbow and this crack is about 20 cm away from the tip. What about my second idea, where I make that part of limb in a "snake", so that snake avoids crack?

[PEARL DRUMS]

that is going to sneak up and bite you later.

  Looking real close, the crack seems to be following the grain....My vote would be to follow the grain and take it out...

How wide are your tips? You have lots of meat there for being so close to your tips. Id say keep shaving it down.

[Springbuck]

  You should be able to follow the grain more closely there and work it into a "snake" as you said, ASSUMING you have enough width both THERE and anywhere else the grain takes that big a wag laterally.

  What I mean is, if you try to follow the grain THERE, you should probably follow it throughout the whole bending limb.

[FilipT]

Yes it is following the grain. This is the idea I have. I did this in Paint.

[Springbuck]

  That looks fine to me.  Just make sure it doesn't also run off the edge anywhere else.

[FilipT]

I will watch every millimeter of this while removing wood haha. Don't want to experience this again!

[burchett.donald]

Filip,
         You will have grain run out again if you don't follow the grain...Green x's show grain run out area...IMO, I would start with a single center line following the grain and then lay out the taper from center...Hope this helps...Check out the purple lines, maybe you have room?
                                                                                                                                                Don

Ash, knots and bending is not a good combination, if you know what I mean......

That ragged looking area in the upper right is just as concerning.

[FilipT]

I removed the wood already and it followed the grain so that limb will look like something in between purple and red lines. That being said, I do agree with PatM regarding that ugly knot. I know that one cannot bisect the knot, but we can remove most of it.

P.S.
What are you all looking at is not the clean back of the bow. This ash has really firm bark that cannot detach from the wood so I removed just the rough parts and this here is a underbark couple of mm thick. I hope that I could find an easy way to remove it. This ash has huge amount of rings and just a small slip on my part will violate the rings.

I've never worked Ash but with all the wood I have worked I spritz the underbark with water and let it soak in for a few minutes, then scrape with a dull scraping implement. Plastic works well. The underbark comes off easily.
