Jig for forming impeller holders from 24 GA stainless sheet.

There is about 0.170" diameter of spring back. I didn't anticpate that or really test for that, so the start of the bend isn't as well constrained as I would like. But it works. Final required OD is 1.225". Mandrel is turned to 1.005".

Finished part. It's very exciting.

Impeller slips right in. The impeller has an o-ring on it. I may add some adhesive as well.
