Failure is a huge part of this game. When I started out, just getting a stick to bend, without a hinge or 4 inches of set was an achievement and I broke as many as I made, as I get better, my standards get higher, and although the number of bows that snap or fall way below target weight is smaller, my failure rate is still really high as I no longer accept things like 4 inches of set. My work area is a small cleared space in the garage about 4 feet deep by 4 foot wide but I have arranged all the household junk so I can swing the end of a bow around to work on one end at a time when I work at the bench - a door strapped to the wall with legs made from 4x4 fence posts. Mostly I work using short fat log (about 14 inches high and 14 inches wide) as an anvil for all my hatchet work. I also use it to brace against for rasping and sanding. Its amazing what a hatchet and rasp can accomplish, I very rarely use a vise for bow building. I'm pretty sure I could get away without a bench or a vice but they are nice things to have.
