Title: sinew
Post by: andybutrick on August 18, 2013, 03:19:27 am
  I built a 68" slight five curve longbow, with a bamboo back, Ipe core, and osage belly.  This bow shoots awesome, quick straight and powerful at 72lbs.  The bamboo is flaking out at a high pressure point.  I want to sinew the back and fix the bow.  Does anyone know for sure if sinew is only good for really short bows?  My thought was to sinew only about 50 to sixty inches and leave 5" or so bare at the tips.

   I've sinewed bows anywhere from 46"s to 68"s. Sinew will work on any lenth bow. I've never sinewed over boo. But I see no reason it won't work.

Sounds like a good idea.  But wont the sinew add like 15# which would make it 87# lets see pics

Combed flax might be an option on the flaking area.By flaking I don't know exactly what you mean.Most times bamboo will pop up a splinter at a node if the node has been taken down too far.

If the flaking is the rind it shouldn't be a concern. A rawhide backing would be more appropriate with less adverse affects on the bow.

I only sinew back bows that I design and plan to be backed from the beginning.

If it's flaking/splintering at a point, and the bow looks done otherwise, just wrap that spot with, well, almost anything soaked in glue.
