Title: Selfbow repair
Post by: rascal on February 13, 2010, 01:30:00 PM
Looking for some input on what I think is a pretty simple repair, I have a 59" nock to nock osage orange self bow that draws 83# at my 25 1/2" draw that has a small splinter of wood that popped loose from the back of the bow.  The limb is 1 3/8" wide at the site of the sliver if it makes a difference and the sliver is less than the size of a flat tooth pick.  It is in the first 3rd of the limb closest to the handle, about 2" long and still attached at the point closest to the handle.

I have some sinew Ive been collecting and thaught that I could wrap the area but I have no idea how to do this properly or if it is the correct repair for the damage.  I could probably chase a new ring and tiller it out as a lighter bow as well.

Any ideas??

I would add super glue under the splinter and clamp it. If the bow is tillered you could put a permanent sinew wrap over the splinter so it won't raise up.   You could also put a rawhide backing over both limbs after super glue in the splinter. That will probably hold it too.

What adhesive do you use to put a sinew wrap on?  And would it hurt anything to put a matching wrap on the lower limb as an accent?

glue the splinter down with super glue.

Then, wrap the area with #4 nylon serving and coat it in 2-ton epoxy.

What Shamus said or silk wrap with super glue. For sinew use hide glue. Yes, you can add another wrap on the opposite limb for symmetry.

Rough up the surface for 1" above and below the splinter.

A little Knox gelatin dissolved in hot water and then kept warm with an old coffee maker hotplate.

I like to put some longwise and then wrap it for at least an inch above and below.

Make sure your tiller is pretty good before since you can't really do much about it afterwards.  Sometimes you just have to live with a stiff spot where you did your repair.
