Outstanding work. 

I thank you for the time you put into creating these build alongs.   In case you are not sure, they are very much appreciated as they are a much better learning tool than any book could relay.  I anxiously await the next installment.  Thank you.

Russ

wholeheartedly agree!
thanks gordon

Thank you all for the really nice comments.

I'll be posting another batch of pictures this weekend that show applying skins to the bow and wrapping the tips.

    Waiting is the hardest part. :P  But the wait is well worth it.  Thank you for all you put into these build alongs.  They are the best!

Nice build along Gordon.

I've never made a sinew backed Yew but the rumoured potential for the sinew to pull the sapwood apart is definitely there, I have seen it happen on other projects I have worked on.  It's not something that happens right away but something that can happen over time.

I hear you Marc. I became aware of the same rumors after I had backed the bow, but I could not find any reports where the rumor was substantiated. What I can say is that I modeled this bow closely after a bow that was reportedly constructed by Steve Alley. The bow was broken so I was able to deconstruct it and saw that the sinew was affixed to a thinned layer of sapwood. So I just did the same without thinking about it much.

In retrospect I might not make the same decision today. As for this bow we shall see what happens. If the backing holds, great; if not, then I will let everyone on this forum know and we’ll have learned something useful.

Gordon, could you add some sinew wraps around the bow at 4"-6" intervals along the limbs to possibly counteract any possible separation of the sap/heartwood?

I could, but I'm curious now and would like to put this theory to a test. Of course if the backing survives that doesn't prove much other than this particular bow was resilent. But if the backing does fail by pulling up the sapwood, then that pretty much settles the question for me. To faciliate the test I'm going to run the bow through a "torture" test using my tillering tree. I figure if it survives 1,000 full draws it's probably fine. If not, well there's always next time...

Science? Nah, I've gotten this far already -  I just feel like going for it. I'm betting she survives the test. So that makes 2 of us so far - shall we start a pool?

And just to make things more interesting: Keenan, if this baby survives I'm betting that she slings an arrow further than anything your side brings to the competition in May. Let the games begin!  >:D
