Title: Sinew only on working limb
Post by: hoosierf on January 09, 2019, 06:08:10 am

It strikes me that a lot of the sinew we lay down on bows doesn’t do much work. Has anyone started sinew at the fades and ended it say 6” from the tips?  I think you would put wraps on both ends of the sinew and leave the handle sans sinew. I was wondering if 1) you would still get the full benefit, 2) if you might get more cast since limb mass is lower, and 3) might cast also benefit from causing less sinew to do more work.

In the end I’m probably really trying to get sinew backed results with less material , faster curing, and less labor.

Has anyone tried it?

I can't remember putting sinew on the last 6" of bow to the tip.Crowning sinew can help conserve sinew too without losing any performance.

I've only done one sinewed bow so keep that in mind. I think leaving the tips bare is a good idea but leaving the handle bare might be another thing. Weight in the handle barely/doesn't affect limb weight and there might be some benefit from having the sinew in a continuous strip. It would tie the two limbs together sort of. I think leaving out the handle would be a mistake.

It depends how far the limbs are bending. If bending area is to close to place where sinew ends it will tear the sinew off. The sayahs of hornbow are also not sniewed.

 I typically sinew just past working limb on the tips, usually just short of where the recurved start. Never made a bone bending handle sinew bow, so it always has a full course of sinew.

I usually don't add sinew to the last 6" of the limb but I do add sinew over the handle area to connect both limbs together. My first sinew bow I just sinewed the limbs and that bow took some set on either side of the handle.

I’ve always done my first layer tip to tip, then any other layers built up where I want it built up.
