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.


I went looking for a picture of your mowers blades. Not a very nice item to clamp on.

If yours look like the one I saw there is a very small flat between the sharp end and the
lift wings.

Which model so you have so I can look into this a bit more?

The one I looked at had a flat section under the edge that a tee shaped parallel and an
angle vise could hold.
