Brushed? You said you want to: [font=Tahoma, Verdana, Arial, sans-serif](1) eliminating ALL machining marks, especially in the curved areas, (2) lather channels, (3) grooves in the handle[/font]
Cut my "losses" with the above hand sanding exercise, and have ordered a mini rotary tool, wool felt shanks, and diamond lapping paste (40 micron to 0.5 micron, roughly equivalent to 320 grit to 10,000 grit) to restart the entire endeavor.
For reference, this was after 1,500 grit sandpaper - looks pretty brushed to me. The challenge here would be sanding in a single direction to achieve this finish.
For further reference, this was after 2,500 grit sandpaper, reminded me somewhat of the Yates stone-washed finish. The remaining machine marks were truly devastating.
I’d love to see what the underside of the top cap looks like currently as well as the base plate. Did you measure out both pieces before you started? I only ask because I’m curious about the tolerances being affected
