Spirals are cut from laminated blanks made up of birdseye maple center, tulipwood and bloodwood.
The blanks were 6 and 3/4 long by 2 and 1/2" diameter.
The steps are 1 and 3/16" diameter by a 3/16" high 33 of them on 8 separate offcenters in the circle. The steps are not glued They are turned from the blank so 2 single pieces. Then placed together for 66 steps. Comments welcome
