I'm looking for a tool that my husband says he saw on one of Bob's shows sometime in the past.(Big help, right? ) He says it's basically a router, with a blade on the bottom/side. It works on wood siding in such a way that it smooths the face of one board and also squares/smooths off the bottom of the board above it at the same time, and you don't have to pull the siding off of the house. Anybody we've asked has looked at us like we're crazy, does anybody know what exactly this tool is and where we can get one?
Thanks in advance!
Michelle
