This is my
circa 1947 Model 111 12"x36" belt-drive Clausing metal
lathe! I was fortunate enough to pick this up from a local salvage
outfit. The story goes that the old fellow that he got it from, used
it for making underwater photography light holders. These consisted
of a series of aluminum bulbs strung together with a small cable like
pearls. When the light was positioned properly, a cam on one end of
the cable locked it into position. |
This is my
gundrill driver setup. After some research, I decided to go with Hypertool
gundrills.
I designed a
few modifications to their standard 1" driver so I could attach
compressed air for chip clearing and screw on a #2 Morse taper
adapter. The taper holds the drill in the tail stock of the lathe. |

The business
end of the drill is shown below and to the left. In section, it looks
like a circle with a quadrant cut away. The end has a spiral ramp
ground in it to shear the bottom of the hole. There is a small hole
drilled just behind the cutting edge that leads to a coolant passage
inside the shaft of the drill for chip clearing.

This is my
little wood lathe. It was my grandfather's. I use it mostly for
sanding and finishing operations in pipemaking. It spins much faster
than the metal lathe. Because the dust is very bad to breathe, I
fitted an attic fan into the window frame that exhausts under the
front porch. |
Here is one of
the x-rays oncologist
Dr. Jack Hutcheson Jr.
from Piper-L made for me of his circa 1920's Henderson pipes. These
were invaluable to me in this project. They say a picture is worth a
thousand words. These s-rays are no exception. The circle above the
bass drone top section is a quarter. I used it to calculate the
distortion in the x-rays. It turned out to be 105.0%. |
