I did this with 1 pc of ribbon wire. I don't know the exact size. It was a gift.
I fastened the center of the wire to the + post first, then I wrapped each drill bit from the top down. It was like sewing. Once I got to the bottom I pulled the wire very tight and went around the negative screws in a clockwise direction. This assured the wire was pulled very tight when the screws were fastened down. I then removed the drill bits and fired the
coils 3 or 4 times to solidify the coil structures.
I boiled 2 pcs of 500 mesh. Other than that, the mesh never was exposed to any heat until they were fired in the
coils. There were no hot spots, no shorts. Nothing to adjust at all.
This is my first attempt at unoxidized mesh. I will never torch mesh again. The flavor is much better. The setup was much faster.
