Been a long time since I came out from under the porch, but I need some wisdom
from the the porch.  I need to make a round sanding device.  About 2" -3" in
diameter to sand the inside of a sphere.  So I am thinking of finding a material
to add a grit to, that will break down as using, to continually expose new
sanding grit to sand a spherical inside shape.
What say the group?
