Hazelnut bow build-a-long (fixed pictures)

YES!!!!
RT,
I think the rawhide technique probably works best where the fractures are localized. Are you seeing crysals all along the belly?
Gordon:
Okay RT, I saw a picture on your thread. That looks like a good candidate for a patch. I use cow rawhide that is about 2 mm thickness. I bet wild hog hide would work great. Otherwise I could put a patch in an envelop and send it to you in the mail. After applying the patch to a limb I wrap it with serving and then do a similar wrap on the other limb for looks. Here's a pic of a bamboo backed yew that I fixed in this manner. The fracture was caused by a knot that came through the belly and was rather severe. But it has not given me any problems since I fixed it - and I shoot this bow a lot.

Great bow as always. Thanks for the biuld along. Joel
Gordon:
A number of bowyers that I hold in high regard have expressed doubts that the rawhide technique I used to fix a fret is effective. An alternative treatment that is proven is to remove wood to below the fracture line and then glue on a strip of matching wood.
Next up - final tiller
Gordon:
The bow gained some weight after the heat treatment so it took a bit of work to get back to where I was previously. I’ve been scraping on the bow whenever I can sneak away into the garage for a few minutes. Here she is pulling 55# @ 25”. Tiller looks pretty good except the left inner limb looks like it may be bending just a little more than I like. I won’t remove quite as much wood from this area as I continue to reduce weight. String follow is minimal at this point.
