Making Titanium Rings/Mark Stone
Shown above are two titanium rings by machinist and lapidary specialist Mark Stone. The simple titanium band in the third photo was turned from bar stock by Sherlineís Craig Libuse.
Rings #1 and #2: Mark Stone is a tool and die maker, machinist and machine designer. He also does his own lapidary work. He uses Sherline tools to make his jewelry, which combine both his metalworking and lapidary skills. In the letter accompanying his photos he said, ìWhen I purchased the milling machine I was afraid that it might be too light and fragile to machine the titanium I planned to use. Enclosed please find pictures of jewelry which I have machined from solid titanium bars and sheet. The faceted stones are primarily cubic zirconia. The blue stone in the man's ring is lapis lazuli. I do my own lapidary work and the Sherline mill is very useful in making special tools.î
Ring #3: The simple grooved titanium ring in the third photo was turned from 1" round stock purchased on eBay. A 3" long piece of stock costing less than $20 will make 3 or 4 rings. If you price titanium rings in a jewelry store you will find they sell for several hundred dollars each, but you can easily make one yourself on your Sherline lathe in an hour or two. Craig Libuse used a 1/2" TiN coated drill bit (3/8 shank), a P/N 2259 boring bar with 80∞ carbide insert and a P/N 2258 set of LH and RH carbide insert holders with 55∞ inserts. It has been worn every day for several years with little sign of wear.
NOTE: Take proper precautions when machining titanium. Like magnesium, small chips can be ignited with a spark and should not be allowed to build up in the work area.

Shop Tip of the month
Using the 7600 tool post as an indicator holder/Dan Pines
†The tip of the dial indicator extends through the3/8" round hole on the P/N 7600 tool post to contact the material in the chuck right on the part centerline.
Pines, Sherlineís dealer in
ìThe P/N 7600 3/8" tool holder is very versatile, and I have found several uses for itófrom holding an end mill to boring work to assembling a dividing head on it. Another convenient use is for holding an indicator. The shaft diameter of my particular indicator is 8 mm. I made a sleeve, slit lengthwise to fit over its shaft and into the 3/8" bore of the tool holder. It is especially convenient for indicating along the length of the work.îóDan Pines
