We apologise again for the fault in the moderation. Those responsible for sacking the people who have just been sacked have been sacked.

It's POSSIBLE that your competitive spirit has displaced your sense of courtesy.

Blatantly stolen from a post by TomB a member here, but I didn't want it to fade away as it seemed like an interesting defintion:



Quote:

The Blakesley Effect is a term used to describe inefficient metal flow, opposite a clip on a coin, when the rim is formed and the subsequent imperfect or incomplete rim formed at that position after striking. -- TomB

I might add to clarify this effect. When TomB quoted "opposite a clip on a coin" it means the effect will be more or less 180 degrees around the rim, from the clipped area.

It still means the same thing, but being "180 degrees out" paints a picture, which I sometimes need.
