James Hyde has used the CNC to cut stainless steel.

Awesome, thanks for the info. This is going to make life way, way easier.
Next task would be to find high-carbon sheet steel and make tempered steel
claws, but, I might leave that for the next project...

Haven't used it- but CNC router should be able to cut steel sheet no
problem. Don't need to use
a grinder- that's what micro carbide endmills are for.
That new spindle shouldn't have any problem doing sheet steel. If it were a
block of
tool steel, maybe not, other than just ridiculously small amounts at a time,
but yeah- no mods,
should totally do that.
The only hard part is holding a sheet down. Mentioned to a couple people
using vacuum pump donation
to make a vacuum table for the manual mill, could make a small one for the
CNC too. Getting vacuum
pump was hard part. Sheets can be held dead flat strongly with them, and you
can mill just the sheet
away if you're careful. I use them every day at work, very familiar with
them.
Otherwise, superglue on steel sheet to a sacrificial base like oak plywood,
and mill into the plywood.
Superglue actually is plenty strong enough to hold materials in place to
machine them- if you don't
take large amounts off in a pass (ie: more than 0.005" depths of cut). It
would work for this quite well.
Just remove with acetone when done. I've machined watch plates on lathes
doing this- if you're careful,
it works.

Are there any aviation tin snips in the shop? I use them for
lighter gauge metals, and the left and right snips are handy for
curves.

I ordered a bit for my circuit board work that should be ideal
for this
- a 1/8" down cut but.

Hey,
I have an idea for a project to make little metal
claw-thingies that fit
on one's fingertips; I know a couple people who want such
things for
costumes. I've seen a few examples that are just made out
of sheet
metal that's been bent and smoothed, but cutting sheet
metal by hand to
make ten of them seems a bit of a pain in the butt. Some
kind of punch
would be ideal but I don't think we have the tools for
that... Is there
a better way? Can we attach a grinder to the CNC router
and use it to
cut sheet metal?
