"Effluvious" -Maple burl, African Blackwood, maple, and brass
The primary sphere for the Effluvious was turned utilizing my Sphere Turning Apparatus, as is typical. The hemispherical hollow required the fabrication of a Cage Chuck so that I could mount the sphere upon my wood lathe and turn out the declivity.
The blackwood sphere was also turned using the Sphere Turning Apparatus, then carefully marked out with a height gage to establish the equator for final turning and splitting in half.
The brass parts were made from 1/4" thick plate on my engine lathe, and incorporated very tight surface details and specific chamfer angles. The 13 radial holes in both of the rings were bored back on my wood lathe utilizing my Direct Indexing Spindle Apparatus and my Horizontal Drill Head attachment for my compound table. The 1/16" brass rods were hand bent into place, with an emphatic twist in the alignment to add a sense of motion and eccentricity to the blackwood sphere captured within.
The brass pedestal riser was turned freehand with gravers upon my engine lathe, then let into a bored socket within a black lacquered maple base.
