Hello again from Finland!
Along the "Corona II" bow I was in parallel making another bow also. This has also ca. 5 mm bamboo and bulletwood slices but now on top of osage. The belly is made of four pieces of osage. First I made two billets from scarp osage gluing the parts so that the joint runs vertically to the back of the bow. The billets were glued to stave with V-voint at handle area. Then I found a bad knot in the lower limb so I cut some 30 cm away from both limbs and glued lemonwood pieces with V-joint as replacement. The laminates were glued to stave with Smooth-On epoxy. Then, as usual, bandsawing and rasping formed this stick to bow shape. I made nocks and arrow plate from bulletwood and fine tuned the bow to 83 lbs @ 28". I wrapped some dacron to secure the osage-lemonwood joints in both limb ends. I found also a couple of knots while rasping the stave so I used some dacron to secure those spots also. Several layers of TruOil, leather handle and dacron string finalized the bow.
I named this bow as "12 Pieces Stick" because of itīs made of 12 wooden or wood like pieces: 4 x Osage & 2 x Lemonwood on belly, 2 x Bulletwood in core, bamboo back plus nocks and arrow plate from bulletwood.
