I've got a tough-dog clamping job to do.

I want to mill my lawnmower blades, rather than grind them.

The blades must be mounted at an angle to the table (tilting the head
just wouldn't work well in this app, because my Y travel isn't enough),
and the jig/workholder must be "indexable" in the sense that I must flip
the blades end-for-end to grind both ends, yet get the same position from
center each time.

No problem on the indexing, but has anyone a good idea for a very simple
way to clamp the blades at a "tilt", yet still hold them well enough to
reduce the chatter? *There is a requisite overhang of about 6" from the
jig to the end of the blade, because there's nothing on the ends you can
clamp to -- little "lift wings" & turbulence slots get in the way.

This seems to be a post in need of a question, "why?". Takes me about
5 minutes to sharpen blades and balance using a belt grinder. Using a
mill would seem to be a use of an inappropriate tool.
