Extending Cutter Life

				Not specifically related to gear cutting but some useful information nonetheless.  Sharp cutting tools used in woodworking leave a cleaner cut than dull ones.  Oftentimes a tool loaded with pitch or glue residue can exhibit the same characteristics as a dull tool but a simple cleaning can restore them to like new.  Instead of purchasing expensive cleaning fluid sold for cutter cleaning, I use industrial strength citrus based concentrated cleaner that you can pick up at a hardware store for $20 or so per gallon.  Soak the cutting tool (router bit, saw blade, etc.) for about 10 minutes in the stuff and brush with a tooth brush and the pitch falls off.  The cutter performs like new and you can re-use the solution multiple times.  Way less expensive than sharpening and it doesn't alter the cutter diameter!
