Title: 47.5" Black locust flatbow (Recurve added and speed test redone 1/23/21)
Post by: eastcreekarchery on December 27, 2020, 04:56:06 pm

47# at 22 inches. 47.5" ntn. Limbs are 1/4" thick at the thickest point and 1.5" wide at the widest point. Took about and inch of set. The growth rings on this piece of wood were nice and thick, and so the limbs are about two growth rings thick. I shot a 425 grain arrow for the chronograph tests. Average of 161 fps for a solid anchor and 170 fps for a snap shot. I may add some reflex but I think the limbs are under enough strain as it is. No fretting or chrysaling at all.

The bend looks good to me and no frets, congrats!  I have found I like 1 3/4 " in width of limbs for that style, especially when getting short in lenght. Amazing how thin locust will get.

The initial speed test for this bow had some pretty impressive results but I'm not sure the chrony was telling the truth. I'm more confident in the new results. I added some reflex to the bow and it now draws 52 lbs at 23". I shot a 520 grain arrow at the 23" draw and got an average of 148 fps and 159 fps for snapshots.

Impressive power and speed for such a short bow. How much does it weigh?
