Problems with JPL 3 in AA in Maille Industry Posted March 25, 2013 · Report reply I picked up some 20 ga 3/32 black ice rings to make a JPL3 necklace, and I found that the AR on it was too big. TRL lists the AR on the rings as 3, so I thought they would work pretty well. The rings were way too loose, and were slipping out of location a lot. I knew that AA wire was a bit thinner, but that was huge. Has anyone made JPL3 out of these rings?
