Title: sinew questions
Post by: Henrik on January 20, 2012, 07:34:19 am
Hey all.

I am considering using sinew on my current project. the trouble is that I haven't got access or conditions to use anything other than a carpenters water based glue. will this work or will the sinew just overpower the glue?

If it will work how should I proceed? The plan is to find the nearest pet store and buy sinew there, hammer out the fibres and bundle them up before applying. Should I soak the sinew and put glue on the bow before joining the two together?

The bow is a Black locust flatbow 2" wide at the handle and 13" to either side, with a taper out to the ends. (total length = 66") I have a nice back ring through the entire length so I don't even know if sinewing is necessary.

Any advise to this newbee will be appreciated :D

   If I had a good back I wouldn't bother with sinew,I am not sure if the glue you are talking about would work or not,I do know a lot have used TB3 with success.
I personally only use hide glue with sinew.  :)

You can use unflavored gelatin powder to sinew back a bow.

Yeah I'm a bit in doubt to. BL is already very strong in tension as is I'm told.

But very nice to know about the gelatin powder, very accessible in food stores around here :D

I'm not a sinew expert, so take this for what it's worth. If you have a solid back, don't mess with it. The real issue may be the length.  Sinew works best on shorter bows. 66" may be on the long side for a sinew backing.

I agree with Jeff.  On a longer bow sinew is mostly added weight.  There's quite a bit of effort and hassle to put it on too.  On short bows, it's a whole nuther deal and well worth the trouble.  Good luck with your bow.
