| Before: Copper Pipe | 
Earlier we made a 
bangle bracelet from a copper pipe and we added a blue patina to made the bracelet colorful. For this  project, we used copper pipe to make a striking, but 
simple neck-ring  that looks great with a turtleneck and an open collar neckline.
Tools
Jewelers saw and saw blades
Bench pin and anvil 
Half-round file
220-grit wet/dry sandpaper 
400-grit
, 600-grit
, 
800-grit, 
1000-grit
, 
1500-grit
Necklace mandrel
Forming hammer, 
rawhide
 or
 plastic mallet
Renaissance Wax 
Step 1
Determine the amount of material you  need. Must neck-rings measure are about 16-inches long, but you may need  a neck-ring that is larger of smaller depending on who will wear the  jewelry.
Step 2
Cut the pipe. Coat the saw blade with 
beeswax
 to prevent the
 saw blade
 from slipping as you saw.  Use your 
jewelers saw and saw blades
   to cut the pipe. We used a 
size 2
 jeweler's saw blade, but you may need to evaluate the pipe you use to 
determine the size blade you need. Steady the pipe on a 
bench pin and anvil as  you cut. Some folks use a tube cutting jig to hold the pipe  steady   while you saw, but we did not use a jig since we found it  more  cumbersome when cutting from a long length of 
copper pipe. 
Step 3
File the ends of the cut pipe with a 
half-round file to remove tool marks from sawing the pipe. 
Step 4
Sand the ends of the pipe using 
220-grit wet/dry sandpaper to remove tool marks caused when filing the pipe ends. Switch to 
400-grit
, 
600-grit
, 
800-grit, 
1000-grit
 and then 
1500-grit,  if needed, until the ends are very, very smooth. Remember: sharp ends  are not comfortable to wear as jewelry-- especially around the neck. 
Step 5
Bend the copper tubing around a necklace forming mandrel. Use a forming hammer, 
rawhide
 or
 plastic mallet
 to move the metal into shape, if needed.
Note:  If you are having trouble bending the copper  tube, then the  copper pipe may be  work  hardened from cutting, filing  and sawing. If  the copper pipe is difficult to bend, anneal the  pipe  with  your 
torch 
 to soften the metal and make it easier to form.  Pickle the  copper pipe with 
Sparex another 
pickling compound in a 
crock-pot
 or 
pickle pot
  to remove oxidation formed when annealing the  copper pipe.
Step 6 
Finish the necklace. Polish the neck-ring. Texture the neck-ring or patina the neck-ring to add color. Treat the neck-ring with 
Renaissance Wax
 to protect your finish and prevent tarnish.
