degreasing before sinew
« on: January 17, 2012, 09:19:13 pm »
i was wondering what you guy's that sinew alot use to degrease your bow prior to sinew?
the first one i did i used lye,{drain cleaner}, but it's a bear to clean up and get rid of, i was thinking dawn dish soap but wasn't shure if it would do a good enough job on it's own, thank's, Bub

I've used Dawn dish detergent in warm water on osage before.  The sinew job is still stuck down and working fine 6 years later.  The water also raises the grain and opens it up so the glue works down in a little better, too (in my opinion).  Your mileage may vary.

acetone, not very natural but has worked well for me. evaporates quickly and leaves no trace. also use it on all wood glue joints.

I don't do a lot of sinew backing anymore, but back when I did I degreased with dish soap and I never had a problem with the backing lifting. I never noticed that one brand of dish soap did a better job than any other.

I got a question, What do you guys do to degrease and remove contaminants from your glue? Also, what would make a sinew back crack all to heck? Would it be crappy glue?

around the painting trade we use denatured alcohol for EVERYTHING,raises the grain,degreases and evaporates in seconds with no residue,a lot cheaper than acetone and healthier!! I've never done sinew before but if architects spec it for degreasing well.....   Ron

On the last sinew backed osage I did I washed the freshly toothed back with Dawn then rinsed with boiling water. I began sinewing as soon after that as I could.
  TMK, sounds like you used too much glue, its too thick.

TMK, I agree with Pat. Sounds like your glue was too thick. I like mine about the consistency of warm olive oil.

As far as ending up with clean glue, garbage in, garbage out. If you put a lot of nasty stuff in the pot, you'll get nasty stuff out no matter what you do to clean it. All of the sinew that goes into my glue pot is as clean as the sinew I'd use to back a bow or wrap an arrow. That way there is no fat and no meat to contaminate the glue. It ends up nearly transparent, sets solidly and quickly and is stronger than anything I've found for sale anywhere.

You guys are so right, you have no idea how right you are. My glue was like a thick paste. Like mashed potatos. :laugh: I feel like I can finally see the light. I have so many sinew scraps, and I thought it was the sinew and not me...  :laugh:

I also wash the shreaded sinew in Dawn and warm water then hydrate it well in warm water before using it.
