62" ntn, 1 1/4" wide 18" out from center, then straight taper to 3/8" tips with overlays, flip the tips a pinch Charlie. You know what I have learned after building all the bows I have? The bows poundage is the biggest factor, all things being equal. I have made all kinds of static recurves and they shoot just like similar weight straight bows, or close enough it doesnt matter. You can make a 40# bow a fast 40# bow, but you cant make a 40# bow a fast 50# bow without lots of "add-on's".
These are just my opinions and findings of course.
