Title: What might be done with these components?
Post by: Knoll on August 24, 2015, 09:36:15 am

Seeking ideas on how to use all or some of following 3 components to form a new bow.

thin piece of jatoba. 63" length x  just 0.3" thick . . . front profile is cut . . . 1.5" wide to 15 1/2" from tips, then taper to 1/2.
thicker hard maple slat.  67" x 1 3/4 x .45
very thin pc of hard maple.  63 1/2 x 1 3/4 x .15

Draw weight/length objective is 45-47 @ 25".

Whatcha recommend?

  jatoba is a nice belly wood but requires absolutely perfect tillering or it will chrysal. The maple can be used as core and backing if the grain is straight. maple is also a decent belly wood but not one of my top choices.

Yup...maple backed jatoba with a maple core tri lam....since the jatoba is kinda thin id make it a slight bend in the handle at the very least...no gluing on a stiff handle. Make it no wider than 1 1/8". Tiller it good.

Ok, flex-in-the-handle tri lam will be the plan.
And narrow width to 1 1/8".
Glue-in reflexed limbs or leave flat? The thicker pc of maple has a bit of reflex 'cause it was once glued to red elm backing.
I usually do 6" long glued-on static flipped tips. OK, or decreased length of working limb a risk?

I'd use the jatoba as the core, the thin maple as backing, and the thick maple as belly.  63" long, 1.5 wide, rigid handle with 8" fade area.

I decided to look in and couldn't resist the issue of the jatoba and maple.   I'm well and hope you and all the old buddies are too

Jatoba is glued to the thicker maple slat. Total thickness of the 2 is about .79". Limb width is a bit greater than 1 1/8" until 12" from tips, and then taper to 1/2". This sucker is STIIIIFFF.

Move beginning of taper further toward middle, or reduce thickness of maple, or both?

Yes, ...both.
