1. a good place to work with a wood vise or something else to hold the workpiece.
2. drawnknife. I wouldn't use a hatchet to make a bow unless my life depended on it.
3. the best rasp you can afford. farriers rasp is large, cumbersome and not very useful for making a bow. they're great if you shoe horses. I've used a pair of Nicholsons(#50, #49) for the last 10 years. great rasps for the money. I recently acquired a hand made rasp from Dean Torges. fellas, this is the only rasp you'll ever need. with a handle on both ends it offers the ultimate in control and comfort. the fine side cuts quickly and effortlessly and doesn't leave behind deep tool marks. the coarse side is vicious and makes quick work of heavy stock removal with minimal effort, and it simply does not clog. see them for yourself at

5. a four inch rattail rasp for nocks. chainsaw file is too long and was made to cut metal. a lousy substitute, imo.
6. cabinet scraper
a hand plane is practially useless for making wooden bows. a toothing plane, however, is quite handy. indispensible if you are preparing glue joints
a bandsaw is a great tool to have for making bows, but not a necessity. well, borderline necessary if you want to make alot of bows or work with board stock. a depth-controlled scraper such as the Bowyer's Edge is nearly indispensible for finessing tiller and precise stock removal. I've used a couple of the knock-offs, and they didn't measure up, imo.
I made my first bow with a chincy drawknife, a cheap 4in1 rasp, paint scraper(careully sharpened), chainsaw file and sandpaper. trust me, the work is much more enjoyable when you have good tools. :-)
