I follow jim hamm's idea out of bows and arrows of the native american's book and never stress the wood before sinew. now i know backing a bow is a whole lot of work for something you never had a string on, but i do agree with him in the idea that potential damage and internal stress could be done to the wood that would not happen if the backing was on. I would back it now, set it in a reflex like you want, tiller it later. just my opinion.  26" on a 48" bow with no backing, impressive!!!

Excellent Thread Sir!

I have a Yew Problem Child stave with this style bow in mind waiting in line.

Thank You for sharing your process! :)

I'll never get it to 26" without sinew and I hope I can then!  ::)

I agree with pauls thinking about not taking any set and stressing the bow presinew if it is your objective to sinew it. I've done it both ways and my results in set,cast,n early draw weight was very noticeable. So I now long string it to the point of bracing the bow and where I have about 5-10 lbs left to reach my desired draw weight,then I sinew it. I wood not be pulling it any further and I wood reduce your weight by at least 20 more pounds from where your at. If your early tiller is good,and your sinew is nicely laid down evenly and equally in both limbs then it just makes life a whole easier when you go to finish tiller it out when she's seasoned.

I can't believe im answering a question for you...you should be answering mine..lol ;)

I don't have a lot of experience with yew, sinew backing or short paddle bows. This will be my shortest sinew backed bow and I'd like to eventually shoot it if everything goes well.   ;D
  I have not pulled this bow beyond 50# and am just working out the draw inch by inch. So far only long scrapes with a scraper, exercising the bend and checking the weight. I'm loosing about a pound per 25 scrapes.
  In the past I have tillered a bow to be sinewed, either to about 3/4 tiller or to full draw before adding the sinew. I hold the the bow in reflex when I add sinew and give the sinew plenty of time to dry before releasing the bow from the form.
  This is how I held the last sinew bow in reflex while I sinewed it. I used a thicker piece of sinew to make a loop around the handle then, with the tips on 2x4 blocks I drew the handle down and hooked the sinew loop to a small screw hook.  When done I just cut the sinew loop close to the backing and that was it. Worked great!!!

Pat I went 23" on a 47ntn. Be intersting to see if this one goes to 26 with sinew. Looking real sweet so far.

I would sinew sooner than later.  The added sinew will bring the neutral layer closer to the back (more so on a wide-thin limb bow than narrow-thick limb bow, simply because you have a lot of sinew on there, and because the limbs are thinner, so percentage wise- you are moving the neutral layer more than adding sinew on a narrow-thick limb bow). So if you wait to add the sinew until after significant tillering, you have been training wood to become tension wood that will need to be compression wood once sinew is added. At least, that is the conclusion I came to laying awake in bed last night.

I sinew later than earlier.  Sinew is too much work to put on a piece of wood until I'm pretty sure it'll make a bow.  I'm never sure before I've bent it at least a little.

CMB, that makes sense to me  :o somehow.  I've read about the neutral plane thing and sorta kinda know what they are taking about.  ;D   I think I'll set this bow up for sinewing as it is. I'm sure the sinew will draw up more as I remove belly wood later. I'm not in a rush at all with this bow. My intended draw weight is success!  ;)
  George, I have brought this bow to brace(about 1") and the string is dead center. From there she has been drawn to 17" so she knows my intentions!  ;)   There is a little prop twist but I'm  not gonna worry about that. The bend to 17" looks pretty good so I guess it is time to move on.
  Sadie, when I quit trying to learn it is time for me to dig that BIG hole!  ;) ...and I'm sure you will agree it's not quite time for that yet!  8)  I still have to build an Asiatic composit horn bow yet!  ::)
