Tension Cracks in Sinew Backing

(1/5) > >>

Marin:
Hello,
I've been tillering a sinew backed bow as of recently and it seemed to be going well. Just today, I was bending it once again to a point I have already bent it to last weekend. It bent fine last weekend and this weekend it still seems to be bending evenly (even checked the bend with a block and ruler to measure along the curve and see if it's bending evenly). I heard very quiet snaps and cracks as I pulled it today and noticed the formation of several horizontal cracks on the back today. I was expecting this to happen at some point as I tend to add a bit more glue than most and I read about it in TBBI  being something fairly normal when making backed bows. However, the cracks seem to be concentrated along a short 5" section and there are quite a number. I checked the bend at this area with my gizmo and ruler and it does not appear to be bending any worse than any other part of the bow, plus this bow is only being bent at about 5" in total currently. I don't mind having these cracks, but I am only curious if this is something that is worse than I think it is? Would this lead to performance issues?
I've attached pics of the cracks in question as well as bow tiller at this point from two different angles. I should note that this bow is heavily reflexed with some slight recurved ends, so at this low level of bending, more reflexed portions are going to look stiff and unbending when in reality they are bending. The cracks in question appeared on the back of the portion closest to the handle.

Unstrung profile for reference

Id say you need to string the bow to see how its bending,, braced it may show that area as week,,
then proceed to even it out and go from there,,

Marin:
So the cracks themselves aren't anything to worry about? Just as long as the bow is bending evenly

Marin:
Also, isn't it still to early to brace this style of bow? I thought I should at least get it tillered up to about 10" of bend or so before I try to brace it.
