I did it!
I tore the skin near the leg b/c I don't think I dunked him long enough in the ice water after the hot. Next time I'll let him sit a few seconds more.
I totally couldn't have done it without all the VERY helpful step by step pictures and instructions on this site.
I have one more that I'll do tomorrow. I only did one today just to make sure I could do it. I'll make a couple changes to my set up and do the next one tomorrow
