Hi, Has anyone tried a router upside down for this problem? It would seem to me that a router could be put on an adjustable, with a bolt in each corner, jig. Another choice, which although messy, would be a power file. I think that is what it is called. The one I have is made by Ryobi, and is a small belt sander. Regards, John M.
