Yes indeed an impressive bend from a piece of fir..........
Better wood,longer and wider and you'll have a good one next try 26 inch draw, stiff handle, sinew backed recurve should be about 58 inch.
Ah come on! Too much man-nee. If that's doable with fir, I'd like to think that a good wood, springy and good at compression, and still sinew, could be more draw weight with the same dimensions, maybe even to 28". But yeah, it probably wouldn't perform as well as a longer one? nor hold much reflex? but short bows are cool
