It really does.

Damnit.

You have to look on the bright side, Gunner. Even If you had been
standing there watching, the cutter would still be FUBAR, except you
might be under some misconception that you might have been able to do
something about it, and feeling worse.

Condolences. Really.

Experience will yield the ability to discern the difference in materials,
minimizing the possibility of a repeat. Remember, the 300 series of
stainless is not magnetic, and possesses a yellow color--not easily confused
with other materials.

Make it a habit to watch your chips when you first start a cut. They speak
volumes about cutting speed and material-------you should have seen the red
flag go up when the chips came off blue. Overheated stainless will be
dark yellow to dark brown.

Using carbide? If so, what grade?

Harold

So the project was good enough for the Special cutter but not good
enough for the known metal pile?

That does suck though

Known metal pile? Whats that? Its all Mystery Metal. I can figure
out the brass, bronze (sometimes) and aluminum..and if its magnetic or
not...but thats about it. I could spend days doing a grinder test.

I only found out that this piece was A-2..cause I found another 6"
chunk that hadnt gotten a bit rusty..and printed on it was Oil
Hardening---A2.

Hell..it cut fine with the band saw, deburred fine with the softwheel,
scribed just hunky dory with the scriber..and the first chips that
came off looked normal. I tend to run a bit fast..tan to blue chips
most of the time on regular steel..and these were not even tan..so
shrug... and the face mill wasnt even carbide..but HSS.

I was making angled sections to go on both sides of my HLV-H ways, to
duplicate the Hardinge carraige stop/dial indicator/micrometer holder
that goes across the ways under the spindle.

So I trammed my Yuasa angle vise to the proper degrees, put in a
chunk, and let her rip at my normal speeds and feeds for this type of
face mill.

That does suck though

Indeed. I finished the accessory gizmo today...still not the way I
wanted it..but it will work while I ponder a better way to be able to
mount a stop rod, dial indicator, 4 position indexing stop and so
forth. Shrug.
The Hardinge one is neat..but Ive never seen one in real life, only
pictures. Same with the unit that mounts on the carraige. In fact..Ive
never seen a Hardinge Steady rest or follower rest except in
pictures..and only one taper attachment..which is my next Hardinge
project. In this neck of the woods..folks for some reason didnt buy
em.

That's odd. A2 is air-hardening tool steel.

I just had to go look..and under the rust..it indeed says Air..rather
than oil. Dim light and rust. Shrug..Good catch indeed.

Which goes to show how little I know about tool steels

Thanks!
