CorvAircraft> snap ring question

[AVLEC]

I would like to know if anybody has a really clear, well lit, close up pic
of the snap ring as sold by One Sky Dog? It would be even better if someone
can give me the correct technical name for it so that I can go to my local
fastner outlet and ask if they stock such a thing.
After reading Mark 's post on how his crank flange walked halfway off the
crank, I just have to have some form of retention even if my crank will not
see any thrust loads at all. T he flange was double doweled but as Mark
pointed out, that isn't enough. I do have a WW safety shaft but with the
setup I am planning on using, it just won't work at all.
Thanks.
