Re: Teak crack
Ditto on wedging open the crack and using a syringe to glue deep. If you use polyester glue, the wood needs to have moisture, as in H2O. If you clean with Acetone or any other solvent you will dry it out and the glue will not bond well. Even just breathing hard on the area(like cleaning your glasses) will help. Clamp firmly but don't squeeze all the glue out. The glue should foam out of the crack if it is working correctly and the pressure of the cure will force it into all voids. Be sure to put paper under the work to catch dripping glue and tape off around the crack. As it stops dripping and foaming you can wipe the area with a damp cloth to clean up uncured polyester glue. The board does look a bit thin but if you use a very long screw and pre drill you should be good for a while. It may fail along a different portion of grain if stressed too much.
