The learning curve is not that steep, and after a few rings, you get the hang of (1) how to get the rod started, (2) how many times you turn the knob to tighten the ring diameter, and (3) keeping the rod aligned with the grooves so it doesn't curve. I'm still struggling a bit with the first part of the rod being a bit straight (after completion of the ring), but I'm sure I'll get that sorted ...
