Here are my 2nd and 3rd bows ever built. For my 2 nephews, ages 5 and 7. Made from Red oak 1/2 X2's. 48 inches long, 47 knock to knock. Artificial sinew strings. Dyed with Rit dye, and sealed with rattle can polyurethane. Cedar used in the handle. Handle wraps are tennis racket handle wraps, with a leather flipper rest. The blue one pulls about 30# at 22, and the red one pulls about 25# at 22. They both really shoot smooth and fast.
