hey Warren! everyone here is well. Hope all is well there.
The tail is stainless. I cut a kerf in the rear section with a hand saw and epoxied the tail in. I drilled a couple of holes in the stainless to giv eit some more holding power. Then used a clamp to bend it. That stainless is tough stuff. Used tins snoips to cut it out and a grinder to smooth the edges. The rear section just spins on a trough wire with what amounts to a tail wrap at teach end, stainless washers help keep it rotating smoothly.
I've been using one and the action is pretty nice. The tail gives a nice little churning action. Flop it around on top like a struggling dying baitfish and it gets slammed!
