Building a kids bow string?

[T Folts]

A guy asked to me build a string for his kids little longbow, it is a bear little blue 40" nock to nock so I will build it 37" long with B-50 my question is how many strands and what size serving.
Thanks

Build it for the arrow nocks.
This is a 20 pound or less bow, right? Any string built with B-50 will be strong enough, so look to the child's arrows to guide the strand number and whichever serving. The Brownells serving works fine.

I typically use 6 strands of B-50 for my kids bows and double serve.

I make them 8 strand so the nocks fit nice.

I just made one with 10 strands of B50 works great !
