Last time I removed sinew, I put the whole bow under the faucet in the bath tub and ran it under hot water. Eventually it started coming off, but it lifted some wood with it. Hide glue is tough stuff. I wonder, would it melt with a heat gun?
"The way of heaven is like the bending of a bow-
 the upper part is pressed down,
 the lower part is raised up,
 the part that has too much is reduced,
 the part that has too little is increased."

Why do you want to remove it? Just cus it looks bad cosmetically? That's easily remedied if that's the case.

Do not heat sinew it cooks it and it will shrivel up. Even very hot water will cause this to happen. I think your best bet is a warm moist/wet towel over an extended period of time. Let the hide glue and sinew rehydrate a bit and slowly strip it off.
Giving it your best effort is what anyone should expect.

You can scrape it off to. Its work.

Steve:  From what I can see, you're sinew job isn't too bad.  To me it looks like you used too much hide glue and maybe tried to fill in the gaps with hide glue, also.  My first few sinew jobs, I did the same and got the cracks in the glue like you have.  It really doesn't hurt anything.  Just makes a lot of noise and scares the bejesus outta ya. 

You may be able to "wipe" some of the excess hide glue off with a warm water soaked rag.  If there's a finish on it, scrape it off first.  It will take a little time.  Its kinda like getting to the Tootsie Roll in the center of a Tootsie Pop.  It'll take a lot of licks but you'll eventually get to it. 

Good Luck!

thanks guys.the reason that i want to take it off is to do some corrections.this is one of the first bows that i had started a long time ago.i didn't straighten some prop twist and limb allignment problems.this was a good stave and now that i know more,i would like to correct these problems and do a better sinew job.i have learned alot since i put up this bow.once i make these corrections,i am going to add some reflex and flip the tips a little.next go round,i'll comb my sinew properly and use less hide glue.

Pat removed the sinew on his bow called Elky I think.  If I remember right he kept moist rags on the limbs for a while.  Maybe he can chime in and give some accurate details about it.
I started out with nothin' and I still got most of it left
