Divide the circumference of one of these circlesinto 10 equal parts, and draw the radii thruboth circles. 5. Select 10 of the thin segments which matchwell in grain, and placing one at a time betweenthe two circumference lines, fit their ends per-fectly together along the radial lines and clampeach in place with a wooden clamp as fitted. 6. Remove one at a time and glue in place, tap-ping gently into place with hammer or malletand clamping securely. 7. Face off on lathe, and mark the circumferenceof any circle on surface thus faced off. 8. Divide this circumference into ten equal partsbeginning at the central point of one of thethin segments, and draw radial lines thru thesepoints. 9.
