JeffP51 just asked to see some progress on my sinew backed Utah Juniper. I cut the stave on a friends property in like August. I started a thread about only using non modern tools and materials to make a bow. I split the stave with a axe, and reduced it with a draw knife. Using dimensions I found on this site for an Ishi style bow. It is 52 inches tip to tip. Flat bow style, from 1 3/4 inches at the handle to sinew hooks for the string. It tapers from 3/4 thick at the handle to just over 1/4 at the tips. I added 1 ounce of whitetail back sinew for the first layer, and another half ounce foebthe second, mostly down the middle of the back. I used knox gelatin as the glue. I did not induce reflex as I added sinew, but it still ended up with close to 1 1/2. The total weight is 12.74 ounces. Strange as it weighed 12.3 ounces before I added the half ounce. I have mostly used 60 grit to tiller as my scraper doesn't work on this soft wood. Here are some photos so far.
