Sinew Backed, Double Curve Bow
Papa Matt:
Yes, Pat...More info on the fish glue please. Also, you said Ishi used to decrown his bows and violate rings to get a flat, level, surface for the sinew...is this to say that you should not sinew a round-backed bow, only de-crowned bows? Do you have an opinion on this?

The fish glue I use is made for furniture restoration work (among other things). It is liquid at room temperature and does not need to be mixed or heated. The manufacturer says the formula is fish glue, a small amount of glycerin, and a deodorizer.
There are various commercial sources for fish glue (just google it). Some of it can be pricey. Isinglass is the most expensive (fish bladder glue).
I suppose I could make my own....someday.
As far as flat surfaces for sinew, no, the surface can be rounded as well. I was referring to the way the growth rings are violated on wide limb paddle bows made from juniper. A straight grained stave of juniper is a VERY rare thing.
JackCrafty:
Here are a couple of photos of a Native American double curve bow showing a single layer of sinew on the back. (A friend sent me these photos of his bow when he asked me to make a new string for it....the string in the photos is too thin and was made for display purposes). Anyway, the length of the bow is 40"....and the draw is probably 20" (typical of most NA bows of this type). It appears that the sinew is a safety feature (to help prevent breakage) rather than a performance enhancer.

That's a bow that your friend made? It looks old. I would have guessed it came out of a museum. What wood was used for it?
