Cracks on back after reflexing

[Pat B]

Any time I expose a new back I always seal it with shellac. I've had 10 year old(seasoned) osage check like in your pics when heat was applied. The shellac will help prevent the checking and can easily be remover. Also the shellac can take the heat where some other sealers can't. It will even take steaming.

great advice Pat,, I have had "seasoned" staves sent to me here in the hight desert,, and started checking the day they got here,,, cant be to careful on a nice piece of wood,,,

Us high desert folk just can't catch a break let me tell ya.  Same thing has happened to me a hundred times over.

I keep a spray can of Bulls Eye shellac on my work bench all the time. Its a little more expensive than the dry or paint on kind but it is quick and easy for these kinds of application.

I get them from time to time,not as bad if I seal the back as Pat said. No problem as long as they don't run off the sides, super glue and move on.
