"Getting The Most Out Of Your Lathe"

So last week I completed the upload of  "Wood Turning Visualized". Here is a popular little book that focuses more on the machine, in addition to wood turning you will also find instruction for metal turning, and metal spinning on the lathe. "Getting The Most Out Of Your Lathe" is another Delta publication, in keeping with the rest of Delta's "Getting The Most Out Of Your ..." series.

This is a short book, but like the rest of the books in this series , it is packed with information. Metal spinning is one of those activities that has been called a "lost art". Modern methods have largely made metal spinning obsolete, but it is still used to produce one of's and specialty work. For the home hobbyist, this is an interesting use of the lathe, that will let you produce shapes that are normally produced on large expensive press equipment. 

Lindsey published an interesting little book on metal spinning that I will scan and upload next week.

So to download "Getting The Most Out Of Your Lathe" go to my Books - Free Downloads page. # 58 - 14 MB - pdf.

"Turning Metal On A Simple Lathe"

Many woodworkers who turn wood often have need to do the occasional metal turning such as facing a face plate or making or modifying a turning tool. For a woodturner focused on his craft, the higher cost of investing in a metal turning lathe is prohibitive.

Back in 1985 Lindsay Publications printed John Maloy's "Turning Metal On A Simple Lathe". By "Simple Lathe" he means a woodworking lathe. The concept is not new, it has been done since lathes first existed with mixed results. What John does here is clarify the procedure and provides info on producing the tools with modern materials and the methods of using them. He finishes off with an example of a model pipe T engine cylinder.

I have turned aluminum face plates and shafting on wood turning lathes. My Delta/Rockwell variable speed lathe came with a cross slide attachment and I have used it to turn the commutator on my tractor starter successfully. I have never tried it, but with care and John's instructions I don't see why steel can't be turned as well.

There are two main requirements The gravers, which John shows you how to make, and a speed reducer to get your lathe speed down to the 300 rpm range. Pictured below is Dave Gingery's plan for a lathe speed reducer from his book "The Metal Lathe". There are many different plans around the web for speed reducers but I do like Dave's plan.

Most people are familiar with Dave Gingery's "Build Your Own Metal Working Shop From Scrap" series. Chapter 6 in book # 2 "The Metal Lathe" is a plan for the motor mount and speed reducer. I like this plan, it is easily built. A hack saw, portable drill, and vise is all that is needed and the offset lock and release is quick and easy to operate. It is easily mounted on other machines, where speed reduction is wanted.
