Next I use the Rotex
with 36 grit in the grinder mode to refine the form and blend
Next the 2" Grex
Pneumatic to bring down and define the "Hard edges at the
perimeter and ridge.
Then back to the die
grinder... Then a 5" ROS with 60 grit to further contour. This
is the general shape....once they are all like this I go back to
insure consistency and reshape the edges and ridge. I will end
up at 220 grit and then finer pads. It takes 1 1/2 to 2
hours per seat to 60 grit as you see in the pics. I have
done a lot of shaped wood objects with hand and power tools.
I can make the same seat with gouges and a mallet in about
double the time and I still finish with sanding.
Final trim on bandsaw.
Zebra is a wood that
prefers sanding. It is very difficult to plane with a
smoother. The Arbortech is a rough out tool and takes a little
experience... it is like a rip blade with 3 teeth and likes to
be pulled with the blade parallel to the grain. So I
didn't have unexpected tear out. The Rotex with 36 grit
blends the dips and hills into a level surface. It is a
process of going from course to fine with care. One slip
and you ruin the seat blank... which is about $80 each at $16 a
You need to stay in
control and take little breaks... the hands and fingers tire from
holding the tools.
