building a sturgeon snare

Anyone got any pics of how to build a sturgeon snare? Dimensions would be great also. I've got one of the cable grip thingies, now I just need to know how to assemble one.
Thanks, Jonesz

Note... since I wrote the article, my preferences have changed a bit. 

I'd use 1" PVC because it fits the line tensioner nicely.  Also, I'd make it around 46 inches long.  It's a good length to easily reach the fish with the snare, plus it can help you measure the slot limit in a pinch.
