Black Palm ring turning blank Size approx 40mm x 40mm x 15mm
More than large enough for all sizes of ring cores.
Black Palm can be quite difficult to work on the lathe. The hard black fibres can be brittle and splinter or pull out.
Very sharp tools and correct cutting angles are required to get clean results. Applying sanding sealer/CA glue etc throughout the process prior will help to reduce tear out.
The end result is fantastic as can be seen on the image.
Not recommended for beginners.
