That's one of the little ones. I've made several.

That particular one is just a knife-edge seal - the diagonal bars round
the edge hold it in place and there are a couple of sharp rings on the
inside edge to form the seal. Some of the others are "stator" rings -
static vanes at the end of the compresor stage.

Thanks.

I presume that these were pulled from over-time engines?

Enjoy,
DoN.
