Sinew Backing

[Running Bear Eagle Eye]

G'day
Im just wondering if artificial sinew will work just as well as the real stuff as it is really hard to find.
And also if you have to use hide glue to attach it.
Thanks

Running bear you might be better of asking this question on www.ozbow.net as this is a taditional site and you will most likely get a lot of helpful hints and tips from the guys over there.
Just a sugestion mate.

Running Bear absolutely no need to go to OZBOW at all mate, there is plenty of knowledge on this site about traditional archery. Speaking from experience artificial sinew will not work like real sinew, it will make the back of your bow safe but will not add any significant performance to your bow. I always use bondcrete to glue sinew or artificial sinew to a bow, it works very well and is more waterproof than other glues, you can buy hide glue but I find bondcrete to work better and much easier to use.
When you are making a bow with backing you are better to keep the bow shorter rather than longer as the backing can add physical weight which can actually detract from the performance of your bow. Whenever you do add a backing make sure that it has plenty of time to dry before you start to bend it as shooting the bow to early will result in excessive string follow and poor performance which defeats the purpose...Glenn...

So you think that artificial sinew will help prevent the bows limbs from failing because thats one of the main things im looking for as my passed to attempts at making a plain spotted gum bow without backing have been a failure.
As for the size of the bow my attempts have been a bow 180cm long
i dont know if i can make a spotted gum bow much shorter as i have been told to keep them long or they will just break.

Running Bear one of the main reasons bows fail is poor limb design for the timber used. Taking for granted that the grain is straight a lot of bows and especially flatbows fail because of the rectangular limb design, this is not a good design for our hardwoods. If you haven't already tried this next time and I assume that you using stock timber make the back slightly rounded and make the belly rounded the same amount as the back, and make the edges rounded as well, don't have a flat back and belly and absolutely no flat sides, the compression from the back is too great for the belly. This is still a flat bow but it will be more efficient than a flat back and belly and side flatbow. You will decrease the physical weight of the limbs but retain the strength, the bow will take much less string follow and be less prone to throwing up a splinter on the back and will be an all round better shooting bow. I know that there has been a lot said about the rectangular section flatbow but it is probably one of the worst designs ever, especially for our hardwoods...Glenn...
