Ok, I realize this thread is forever old, but Google (or was it HBT?) search brought me here and so here we are.
Thanks so much to wyzazz for the
McMaster pointer! I was going crazy finding people selling these locking rings for $3-6 each, then doubling that with shipping costs ($34.95 to ship 10 rings -- srsly?!?!)
Hooray, McMaster! ~$1/ring, which seems quite reasonable (and allows them a hefty profit) -- yay, yay, yay!
Except... (There's always a catch, isn't there?!)
Now I need to know the dimensions of a standard Sanke ring -- ID, OD and thickness -- to the nearest 0.001"
"Anybody got one o' those...?"
Thanks!
