Prototype 1

The rim lathe pictured here represents my first attempt to create a practical, accurate machine. It utilizes a lathe head from an inexpensive Harbor Freight wood lathe constructed of sheet metal. I used two different types of cross slide, both from Enco. This lathe was sold to a local maker in Arizona.

Notice the extension that goes past the base on the right cross slide. This was a retrofit because I miscalculated the proper distance from lathe head to cross slide. more...

Prototype 2

The lathe head is from a typical Chinese-made lathe. This was a big improvement over Prototype 1 because it is cast iron. It features a variable speed control. I was able to simplify the base design and keep the cross slides on same level as the lathe head. I used two identical Enco cross slides. 

Several of the rims in my gallery were made with this lathe. My only dissatisfactions with Prototype 2 were a lack of slow speeds and tendency to slow down during heavy cuts. I also tired of turning crank handles endlessly, so I vowed that Prototype 3 would have stepper motors and CNC controls to do the repetitive work for me.

Prototype 3

I had some very aggressive goals for this lathe, including:

• Enough rigidity to cut non-ferrous metal
• Variable speeds from 30 to 1200 RPM
• CNC controls
• Enough swing to create a bluegrass resonator.

I failed to create a lathe that could cut metal, but the CNC controls are really cool. more...

The Dan Pennington Standard Lathe Modification

Dan Pennington has engineered a modification to a standard wood lathe so that can support two cross slides. The beauty of this scheme is that it eliminates the need for a custom welded base and workbench or cabinet.

The Dan Pennington Single Cross Slide Approach

Dan Pennington has engineered an approach that uses a single higher quality cross slide. All the cutting is by boring bar.

The Frank Rotella Classic Build

Frank Rotella built this lathe in the classic way, combining and imported lathe head with a welded base. He went one step further and added a heel cutting jig.
