Youth all-wood tri-lam suggestions needed

[eflanders]

I am the proud uncle of two lovely young girls who have taken a shine to shooting archery and doing it traditional to-boot.  I have built quite a few all-wood tri-lams for adults but never a youth sized bow previously.  My current forms just will not work accordingly.  At this point I think I am going to put together an adjustable form like what Roy uses for this and other bows.  I would guess that a glass bow is probably the best for kids, but I have never done one before (and quite candidly I really don't want to for these 2 either).

The guidance I am looking for from all of you is some basic dimensions like length overall and poundage.  The girls are built very slender and not very tall for their age. The oldest is 13 and the other is only 10. I was thinking something in the 20 - 30# draw weight range but I am unsure.  

What do you suggest and what are your own personal experiences in this sort of project?

I haven't made a kid sized tri-lam, but I'm thinking about making one for my daughter over the winter.  She's 21, but very petite and her interest in archery comes and goes.  She loved The Hunger Games, so I'm hoping that a Katniss type bow will get her interested in shooting some arrows with her old man    
Anyway, here's my guess at a 25-30#  hickory backed osage bow for her.  I'm going to skip the core lam, because I don't think I'll need more than 1/2" total thickness at the fades.  Backing is 1/8" that I'll just free hand taper to about 1/16" at the tips on my belt sander.  Should be able to bend the 3/8" osage belly lam to get that R/D profile off the form, o/w it bends easily with dry heat.
Guessing again here, but I'd make it 1" wide for a little less than half the length of the limbs and taper to 3/8" tips.  My daughter is 5' 3" tall and with her short draw, I think 60" long with an 8"  handle will be okay.  
Hope this is some help until somebody who has made kids' bows chimes in.  I live in Neenah.  Go Pack!

I think 30 pounds @ 28 would do for a young girl who will only draw maybe 18 to 20 inches. You want it light enough that they can handle it and enjoy shooting. I wouldn't go any shorter than 56 or 58 inches. A real short bow is a bugger to tiller and they have more weight being so short. I'd make the belly lam 1/4 thick, the core lam 1/8th thick and the backing 1/8 thick, tapering the core and backing about 1/16th. An inch wide at the flares, tapered to 3/8th at the tips.
