The first bow is all Hickory. 59 inches long, and pulls 30 to 45 lbs. The second is 64 inches long, and pulls 25 to 40 lbs. Front limb is Ash, and the short limb is White Oak. I used what wood I had at the time.I tried making the back limb 1/3 ,1/2, 3/4 the length of the front limb to get better performance with no success. Unique, but not practical for hunting, but fun to shoot target with.. The 2 limbs are attached with dowel pins ,glue ,and thread wrapping. Some guys that have made them claim they relax some at full draw. I haven't found that to be true. Mine stack at full draw. Saved these 2 for my grandson's as a keeps sake.
