it varyies fron bow to bow,, If I had to make one fast I could,, but I usually am working a little at a time when my schedule allows, so have no idea how many hours I have in a bow,,, I try not to work on one when I am tired,, I have been working on one now for several months,,but can make one in a day if need be,,,starting from a stave,, but I dont like working that fast,, I am usually working on several bows at a time,, maybe 5,, so that is hard to keep track of,, I will rough out the stave with a band saw if available, but like using hatchet and draw knife too,, ok,, sorry for the vague time frame,, but thats how I do it now,,
