About an hour start to finish with 40g. I haven't made any since these.
I do my round wire spacing at almost full speed (about 1500 to 2000rpm). The fuse starts on a twist and ends on a twist so when I cut the spool wire off everything stays in place. Then I glue 1/2" on both ends and 1" in the middle.
Cut everything down and bring your frames side by side without flipping either piece.
Sit your stack between the frames and with everything laying on the table nice and parallel/flat just glue the stack in on both ends. Bind the very last bit of both frames together, hook the swivel with one end and put the other in the drill. If your spacing is good you can just keep the spool at your desired angle and fuse pretty fast...if it's not you'll have to weave that shit.
Some of my builds like this had shitty spacing so I'll measure it out make hybrids. When the weave angle gets to be too much you can skip fuse or go from skip fusing to full fuse to help your angle.
