Machinability v Mess v Finish.

Raymond, no worries mate, because had you pared the 90 down to 70 your next job would almost certainly be 85 sods law being what it is.

Hi Raymond,

Like you I get steel for free from a local skip. Most of it is hot rolled black mild steel, but some is a Cr Mo steel (En19? )wich machines well and you can get a good finish. I use it for axles, mandrels etc. and also when I need a piece of scrap metal for some temporary jig.

Hi Neil,

We had a small incident at work a while ago when two new female apprentices were just starting the milling course.

We use a piece of EN1 Bar for the job and within seconds of taking the first roughing cuts both were near to throwing up and complaining about the smell.

I double checked and both were vegetarian (actually one was Vegan).

I suppose thats another Risk assessment Hazard I have to allow for now

There seems to be 4 years gone missing from this thread ! Or is it just me ?

Lofty,

Were you cutting dry or is it really some byproduct of your cutting oil? I suppose you could always use a vegetable based oil to cure the problem

No its just an old thread that someone has dragged up

This is an ex-thread. It has ceased to be.

Hold on a minute it just moved !

Thread Necrophilia at it's best!

Yep, cutting dry with a tipped facemill.

Apparently I'm often heard to mutter something along the lines from Apocalypes Now ' the smell of the first cut etc.

Its probably some coating thats been applied at the suppliers.

Nah, just thread restoration.

Live and let Die.

I see what you did there.

As long as it doesn't become a cross thread.

I'll get me coat....

Just tap on the door and they'll let you out.
