If you have a vise and presuming that this is "soft steel wire" and not spring wire. Put a piece of rod a little smaller than the ID of the loop you want to make into the vise jaws positioned vertically. Bend the wire around the rod about 450 Degrees leaving 4-6" on what will become the part wrapped around the other part of the wire. This is so you'll have something to hold onto for the next step. Most of this will get cut off later. Remove the wire from the rod and clamp the loop in the vise with what will be the long part of the finished part vertical and the 4-6" end more-or-less horizontal. Wrap the 4-6" part around the vertical part a turn or two or however many times you want. Cut the remainder of the wrapped 4-6" leg off with an abrasive cut off wheel taking care not to nick the other wire. Thread the free end of the long wire through the new loop . Repeat. You will be throwing away a fair amount of wire, but you need the length to get adequate leverage to bend a tight wrap. You could experiment with shorter lengths gripping the end with vise grips or maybe slipping a piece of pipe or tubing over the end of the wire. By the time you get to number 19, you'll have it optimized. Good luck.
