9x20 Lathe

4 Bolt Compound Clamp Cast Iron

Image of Finished Cast Iron Clamp

Pictured to the left is a 4-bolt clamp for the 9x20 compound. I originally built a 4 bolt clamp out of steel (see picture below). It was only 1/2" thick. Later I built this one from cast iron. It is 5/8" thick. Follow the link below for information on how to construct your own 4-bolt clamp.

CNC Conversion

At the left is a picture of the lathe at the current state of conversion. It is actually working, but it still needs a cover for the z-axis ballscrew and an encoder for the spindle.(12/01/2007)

I started on this and then took another fulltime job. So I didn't get anything done for a couple of years! After too long a delay I am about to start work on this again.

4 Bolt Compound Clamp Steel

This clamp was replaced by the cast iron clamp above. The cast iron clamp is thicker and more rigid.
