Title: split in bow back, any ideas?
Post by: Eric Kol on January 08, 2008, 11:22:55 pm

Hey folks. While chasing the growth rings on a buckthorn stave, I noticed a crack in the back. It is very very tiny (thin) and about 2" long. It is with the grain and does not violate any fibers. It also does not show on the belly. Can I "fill" this with wood glue? Can it be saved with backing? should I even attempt to tiller this or back it first (if indeed that would help). I hate to give up on it as it has proven to be a bit of a pain to find suitable buckthorn for staves, but if it will be a waste of time...... Perhaps I could try to get two billets out of it?

probally a dry check. I'd fill it with super glue not wood glue. As long as it doesnt run off the edge of the limb it should be ok. You could wrap it with super glue soaked thread after tillering for extra insurance.

I'd do as Ryan said with the super glue but its probably not necessary to wrap it. If it is a small check fill it and let it dry for a while. If it is bigger, fill it in sessions. I have used fine saw dust and super glue to fill large checks, voids and knot holes.
   Will you post pics of the check?     Pat

What Ryan and Pat said,we have a lot of Hickory do that and as long as it is lenght wise with the grain and no run offs it will be fine.Not sure with buckthorn but with Hickory it ant a problem. :)

What the other guys said...! ;)  Fill it with superglue and consider it a mark of character. :)

Seal the back again. Apparently your stave is still loosing moisture and that is why the check in increasing.   Spray shellac or carpenters glue will work fine to seal the back. Get the stave to floor tiller stage and clamp it to a form and allow it to dry a bit more.  ;)  Pat
