Making the nut into a ring is a process of stock removal until the desired shape and fit is acheived.
The inside bore of the nut was not large enough to fit my finger, so I used a die grinder to enlarge the bore and smooth down the threads.
Grind off three of the six points of the nut, continue removing stock to create a rounded bottom for the ring. I used 3M abrasive discs on the die grinder.
Remove more metal from the nut to make it thin enough to fit comfortably.
Hand sand with progressively finer grit sandpaper to smooth and rough polish the ring.
There are several options available to prevent rust, I oil and wipe down my ring on a regular basis.
Step 1: What You Will Need.
Grinding tool; die grinder or a dremel tool
Grinding stones or carbide grinding bits
Abrasive discs or a sander
Sand Paper; medium to extra fine grit
Step 2: Inner Bore
Step 3: Stock Removal and Shaping
Step 4: Sanding and Finishing
To prevent rust I oil and wipe down the ring.
You could give the ring a shinier polish but I chose not to because I beat the crap out of it. Electroplating is an option I may explore down the road.
