I have some decorative wood pieces held to a metal gate by lag screws. The stuff is old, about 25 years, and the wood around the holes has shrunk, so that the screws don't tighten quite properly.
Is there anything I can pour into the holes that would cause the wood to swell, and maintain its shape? I know epoxy would work, but I may want to take it apart again.
Wood is probably douglas fir.
