Degreasing back sinew?

[LeightonM]

I'm liking this thread. We are butchering a beef and I'm saving the back sinew and its really fatty, so this info is on point for me.

Yep, I process the sinew and then I wash the back just like Pat said, then I wash all the sinew in bundles pre sorted for amount and length that I also separate for each limb on separate boards after washed and rinsed.

One thing I have started doing is getting a pot of hot water by my glue pot and I dip each bundle in the hot water and ring it out good before it goes in the glue. I think it helps to warm up the wet sinew before hitting the glue and helps keep the glue pot from cooling off too quick. After a few bundles of cold wet stuff it was loosing heat quickly.

I used back sinew on 2 bows and really like how it turned out. I get a lot smoother application with back sinew then leg sinew.
 LeightonM, On my last 2 sinew backed bows I use cow leg sinew and I liked it better than any other I've used. I got it already cleaned and shredded so I liked that part best of all.

If taken to the same diameter leg is softer than back.
To degrease acetone is the business but I guess any strong enough alkali will do the job.

Makes sense, has anyone tried using acetone on sinew?

[PatM]

Charles Grayson recommended acetone. You don't need to mess with toxic solvents and worry about exposure and discarding it.  Just use the strong soap.

Sounds good, thanks guys
