crack in back
« on: January 10, 2020, 04:04:39 pm »
Got through the sapwood and found this. Fatal? Could shorten the bow and thin the limb and eliminate the crack. It would end up being a teen/young adult bow but that is fine too.

Jim, follow the grain the check is on. If it stays in the limb and doesn't run off you should be OK.

My first thought is can you eliminate the crack?  Is it wide enough?  If so, that’s a possibility. If not, so long as it does not travel off the edge you could be fine like it is.

I would add thin super glue to the checks.

Rawhide sounds good, probably not needed, but I like it

What caused that check? Tension in the wood as it dried too fast. Is all that tension gone? Could it open up when shooting?
Sure you could try and fill it with CA but personally I'd remove it. Osage can do 80# @ 1 inch wide.

Checks are generally caused by drying, as the wood dries it shrinks and if not prevented by sealing can pull the wood apart along a grain. I would seal the back and if you expose another back ring later seal it again and keep it sealed until final sanding and adding the finish. Shellac works well for the sealing because it can be easily removed when you want it gone.

 I assume it is osage. Carefully, drawknife it away. It looks like it is beginning to run off the edge. That is what I would do. Jawge

It is Osage and the guy I got the stave from removed the bark but didn't seal the back. Probably 10 years ago. It is probably about an inch at the narrowest point. I am still chasing the ring  on this stave.

Even at 10 years the stave can check when new wood is revealed so seal it as you expose a new back ring.

I still feel very optimistic that it will make a bow,, ,, however you decide to resolve the issue of the check,,
osage is amazing stuff,, if it was mine I would leave it wide and rawhide back,, but taking the check out would make just as good a bow,, pretty much your call,,
