first let me say i have not repaired a splinter.
this rawhide "repair" was from a wind check that got mighty close to the edge of the bow.
even tho it was following the grain and at the end of the crack the grain turned back in towards the center of the bow,
i didnt feel completely confident doing nothing
i cant even say it is a permanent fix, but its held for hundreds of arrows so far...
all i did was soak the rawhide in water after cutting it to proper dimension to fit around bow tip
then stitched it up with artificial sinew.
when it was still wet the edges of the rawhide were just touching.
as you can see in the pic the rawhide shrunk quite a bit when it was dry
that puppy is on there tight
hopefully you will get some of the fellas who have years more experience than i to give ya good advice.
