It is too brittle and perhaps there are other circumstances that affect it. In certain circumstances it works perfectly, for example pinblocks or repairing stripped screw holes. It seems to me that when it is absorbed by the wood and you are not relying on it as a "glue joint," it works best. I love it for repairing stripped Steinway rail screws (not split rails) and have effectively used it for many years with no failures. There is a specific technique to make it work correctly though.
