Crazy lathe work
« on: April 27, 2013, 12:06:03 PM »
I recently went with a buddy to see some guy turning a piece of artwork on a big lathe. The work piece is 6' X 3' and weighs 200 lbs.!! Shocked
His lathe is an old milling machine he converted. It was turning around 200 RPM's and not going fast enough for him to get a smooth cut. He was scared to speed it up and I agreed.

It is mesquite.
I filmed this with my phone and it is poor quality but you can get an idea of how scary it was.

Let me try to explain this.  I saw a picture of a much smaller one he had made.

He took two sheets of 3/4" plywood 6' X 3' and epoxied them together.  Then he took mesquite cut into 2" X 2" X 6' long pieces and laid them side by side till they were 3" wide.  He did not glue them.  He then took the plywood and placed it over the mesquite and bolted through the plywood into the mesquite strips.  He easily used a hundred lag bolts to do this.  He did not put any bolts in a 3' diameter circle in the middle.  This way he wouldn't hit any of them when he turned it.

He bolted the whole thing to a large face plate and mounted it on the lathe.  His plan was to turn concentric circles to a diameter of 2' 9". 
It was going to look like an archery target with alternating humps and valleys.
After it was turned, he would remove all the lag bolts.  He would then have 18 strips that he would glue together.  He would glue them together in alternating heights.  One high, one low, one high, one low, all the way across with height differences of maybe 6" to 1'.
 
It actually looked pretty cool.  He had one for sale that was only 3' tall for $1500 in an art gallery and someone special ordered a big one.  That was what he was attempting to do when I filmed it.
 
I have no idea how it turned out.
Did any of that make sense?

Interesting. Post a pic of the end product if you get a chance. One of the smaller examples might help. It do definitely look like it could dislodge and brain the operator. ear

I'm thinking that there's got to be an easier way not to mention a waste of wood.  Perhaps I'm not following the process.  All that aside it does appear to be dangerous.

Alan,
The finished product will be just over 6' tall and 3' wide.  The only design is the turning in the middle 3'.
I suggested to him that I thought it would be easier to set up a router somehow and do it that way.  At least you wouldn't have to be afraid of your work piece. :o
 
I will not have a chance to see the finished product.

Router is what I was thinking. Maintain current setup but very slow speed. Add a second router to remove stock and have a smother finish.

Maybe he will send you some pictures. ear
