Well perhaps we need to further qualify things then. When I speak of how long it would take me to make such a bow, I'm counting everything involved at my regular pace, enjoying myself while making the best I'm capable of... not how fast I could possibly crank out something 'serviceable'... like it was a race and my life depended on the time... instead of the bow :^)
Heck, I'll bet it takes me 2-3 hours just to final sand and apply the finish. At least aother hour for the string, rest, grip, etc.
The last sinew and fish backed osage recurve I made fought me most of the way and I bet I had 50 hours or more of actual working time in it.
