I finished the write up on the Amsteel to Sta Set halyard splice and have posted it on my web site. Brion, thanks for your encouragement and help.
The specific example I posted splices 1/8 inch Amsteel to 1/4 inch Sta-Set but this would scale to 3/16 inch Amsteel and 3/8 inch Sta-Set. It is easier to make in the larger size particularly using Brion's splicing wand.
I pulled a sample until the 1/4 inch Sta Set broke and have cycled another splice several times to over 1,000 pounds.
