Taras,

I have just finished moving from Houston to San Antonio so my files are
packed but in general:

I build a one piece 60 inch recurve with rather narrow limbs and fairly
aggressive recurves. This gives me a recurve that weighs about 20 ounces
has long working limbs due to the 18 inch riser, is smooth drawing out to
about 31 inches and shoots a 675 grain arrow at about 190 feet per second.

In order to do this with the narrow limbs, it requires a thicker core than
your typical recurve. My wood to glass ratio averages about .44 glass to
wood. In a typical 60 pound bow, this would be

2 each .040 clear glass laminations for facing and backing
2 each .120 actionwood laminations with .002 tapers
1 each .030 colored coretuff lamination between the wood cores
( I use this coretuff to provide dimensional
stability due
to my narrow limbs and since I shoot fastflight
strings)

for a total thickness of .350 at the butts. On my form with the 18 inch
riser, this works out to about .330 inch thickness at the fadeouts and .250
thickness at the nocks. My limbs are only 1.125 inch wide at the fadeouts
and are only .6 inch wide at the nocks. I use a straight taper from the
fadeouts to the nocks.

On a typical recurve with limbs that are 1.5 to 1.75 wide at the fadeouts,
the wood laminations may only total to .120 to .150 inch thick.

Lots of luck and don't hesitate to e-mail if you have questions.

Mike

Hi, All !
At last I've made my bow. But what i am upset about is my limbs are
too weak. The bow is 49" long. Each limb is 21" long, 1.25" wide at
the riser and about 0,6" at the nocks. I used straight taper. Each
limb has the same width all the way - 0,173" (4.4 mm)- 4 layers of
ash
wood (0.6 mm) and 2 layers of fiberglass (1 mm). They have fair
recurves at the ends. The limbs were kept in a heating box with 2
