Dan and John,

I was thinking of something like Loctite to secure a 1/4 inch bolt in the bushing, using a wrench and some
'pulltwist' to remove the bushing from the wood. If there's a problem with the inside surface of the remaining
'hole' a Forstner drill bit might be utilised to make the new hole a little wider, and if required a maple 'plug'
inserted, cut off and sanded flush after which pilot a new hole drilled.... hopefully the bushing might
then be screwed back in with a small amount of epoxy glue on the thread to make sure it will be secured in
place.
