The "Woodturtle"
CNC Wood Lathe Add on
During the summer
of 2004 I was doing a 20 mile walk. I use these long walks to reduce stress
and to run design ideas through my head. One of my walks was from North
Arlington over to West Orange and up Eagle Rock Ave. At the top of Eagle
Rock Ave, and across the street from Pal's Cabin there is a lake next to
the corporate center. As I walked the path around Crystal Lake I
saw something up in a tree. It was not a bird, squirrel or rat. As
I walked closer I could see it was a turtle! As I got closer the
turtle jumped out of the tree into the water and it swam towards me and
then down out of sight. I then looked to see how the turtle could
have gotten up in the tree. We had lots of rain in the summer of 2004.
The base of the tree was under water. The branch of the tree came out of
the water and gently sloped out over the lake.(end of turtle story for
now!)
Now I am deep in the
Jester project doing all kinds of tests and drawing. Some of the
people in my group ask me if I am ever going to design a CNC lathe. When
I dream I sometimes have people in the dream ask me if I am going to do
a lathe. I always tell them the spindle is the problem. There is no cheap
way to make a spindle assembly. I give the same answer in my group as in
my dreams. Also in my dream I start telling people about the turtle who
climbed the tree. I get the same reaction in the dream as in real life!
(a pattern is forming)
So now I am on the
last few drawing on the Jester project. I am looking forward to a few weeks
off after it is finished. I am laying in bed thinking about what project
I will do next and where I will walk to the next nice day. Lathe No! Walk!
Finish Jester! I fall off to sleep. At around 2 AM I wake up out
of a dream. I don't remember the dream exactly. All I remember is a turtle
going back and forth on an axis with a cutter strapped to his head and
people looking on in disbelief. As I sat on the edge of the bed trying
to wake up I saw the entire machine design-Name-Hat and Software solution.
The whole thing! I then went over and switched on my computer and
reported this event to my group. Guess what? The idea was met with disbelief.
The Woodturtle
is a CNC wood lathe add on. It is the simplest CNC machine anybody has
ever produced. It is designed to be used with cheap wood lathes. Other
people have used an X-Y assembly on a wood lathe. This one uses a cutting
bar with a carbide insert. You can also make your own cutting bars.
The cutting bar moves in and out of the dust guard like the head of a turtle.
The Woodturtle
only works with wood lathes. The 20 page booklet showing how to build the
Woodturtle Booklet is $36 US,Canada and $42 to the UK and Australia. Other countries see Order page for instructions.
