I build a kid's recurve. It's a slightly scaled down version of what I call my recurve #3. For kids I build it 48" NTN. The bow ends up being roughly 1 1/4" at the fades. Limb taper is strait from the fades to about 1/2" at the tips. 16" riser.
.030" glass
One taper @.002 per inch, .090"
One parallel @ .040"
.030 glass.
Total stack= .190"
Draw weight is about 16-18# @24". About 10-12# @ 18"
This can be increased for bigger kids.
