preventing sinew drying cracks

<< < (2/2)

sonny:
I took a couple of pics but don't think they'd show very well.

the sinew was applied one course at a time.
It seems Tom Sawyer is likely on the right track in that the blank should have been pre-tillered a bit more,, but then there's the problem of inducing too much reflex (making a very unstable bow blank,, been there, done that) as the sinew dries. I guess there's a happy medium in there somewhere that I need to find.

I think now I have at least made up my mind that I won't continue on this bow but will soak the sinew off (however much I dislike that chore) for use on another project..



 

tom sawyer:
For less reflex, use a thinner layer of sinew.  ERC is pretty light stuff, a thin layer of sinew should work on it.  Maybe even put it down the middle, and taper off to nearly nothing towards the edges.

I've never been able to make myself recycle sinew.  As tough as processing tendons is, sokaing it and resorting it by length is even worse.  More power to ya, do you have any tips for recycling sinew?

sonny:
....only tip I can come up with is "grin and bear it" ;)
 

Hillbilly:
I remember a pic of a bow in Jim Hamm's book, I believe it was a sinew-backed yew, that had huge scary-looking sinew-induced checks on the belly, but he said that it shot great.

Marc St Louis:
Can't say I've ever had splits develop when sinewing and I have sinewed a number of bows. I apply sinew a bit differently than many though. I mound the sinew down the center of the limb and only put down a couple courses on the edges.
