Gav, what you describe is known is a climb cut. My first router, that I abandoned because it ceased to hold router bits (two were launched into what I presume is low earth orbit) came with a manual that extolled the virtues of climb cutting. The cut edge may be smoother and have a distinct finish. What the manual failed to mention was the danger associated with climb cutting. My second router, the Makita 3612C, came with a manual that warned against climb cutting. Part of the terminal segment of my left forefinger was turned into some resembling unprocessed hamburger in far, far less time than it took to type even one word when in one unthinking moment I did a climb cut. The workpiece shot away and my finger made contact with the spinning router bit. I am very fortunate that there was no damage to the joint or tendons, but weeks of rinsing with hydrogen peroxide and bandaging in such a way as to eliminate joint flexibility have left me now, weeks past two years, with a forefinger with limited flexibility. Based on what I have seen in the shop safety forum, I consider myself very fortunate. Thus please for you own safety, and the safety of anyone or anything that might be in line of fire of the workpiece, please heed the words of curiousgeorge, steelbreeze, and Hamlin. There is also an extensive discussion in the thread Direction of Feed. Far too many injuries far worse than mine have been described, sometimes with graphic photos, are described in Shop Safety, and few of these are attributable to climb cuts. Bottom line: climb cuts are very dangerous without proper precautions including deliberate planning and very tightly holding down the workpiece and using push blocks or push pads that keep fingers and all other body parts far, far away from the spinning router bit.

- Wood working, especially router work is too much fun to let "disabilities" get in the way.
