June Program:
The Oneway “Hisway” Coring System
by Oskar Kirsten
MULCH. That’s what good
wood turns to if you just remove
the center layer after cutting
layer. Imagine a big nice piece
of bowl wood with grain up the
wazoo and color to match. The
center of that goes away in chips
to a flower bed. But, now there
is a way to salvage that center
wood without the frustration of
the McNaughton Nightmare. I
know that from experience since
I have had two McNaughtons
over the years. I made lots of
niece bowls with unplanned
drain holes. The flowers I planted
in them liked them anyway.
Mike Mahoney can wiz us with
what he can do, but we mortals
have been saved by the OneWay.
So for the June demo I will try
to show how I am now a much
more calm person since I have
developed the confidence to
make several nested pieces out
of a single piece of that “special”
wood. The demo will include
the important set up and the options
it allows. There are ways
to avoid that bottom hole every
time. Really. Included will be
the methods of properly grabbing
the pieces for the methods
of nest progression. As time permits,
I will show how I changed
the stock OneWay mounting
plate to be able to do more that
hemispherical sections and see
the options.
Set of nested 4 pieces from a
Eucalyptus burl that I had for 10
years not wanting to McNaughton
it. (Good thing, it became
the introduction page to last
year’s (2012) Utah Symposium
DVD)
This a Carob nest of 5 pieces
and clearly shows what can be
“saved” from the mulch pile.

form with legs
This a redwood burl set of 4
pieces using the same cutter to
generate concentric hemispherical
sections. The set is 16” in
diameter and about 6” tall.
The ONE admitted McNaughton
nest that worked. It is a rare
Carob burl and it is less in diameter
than deep!!
Very hard to do and will remain
an orphan unless I repeat this
with the OneWay.
