Nope, means the same this side: straw colored. Left side of the reddish in this range of tempering colors: A scribe needs to be very hard to scratch a line, and not wear quickly. Left side of the range above is hardest. A lathe tool needs to be a bit softer, so it isn't brittle and doesn't shatter (though still hard) so it's on the right side of the color range. Past the color range on the left is full hard, and past the color range on the right is full soft (or annealed). |

You said it fine Stuart. I just added a picture..... |

I just found another chart that shows lathe tools and milling cutters toward the straw side, so I guess there's a range of opinion. (I've actually made and used an Acme threading tool that was full hard, without tempering, and I didn't manage to break it :scratch:) so I don't know really what is best. With this kind of stuff, you just make it and see -- if it breaks, temper it further, if it wears too quickly or doesn't cut, temper it harder. Small tools are very quick to make and try out, and inexpensive. |

Thanks for the help gentlemen, I'm going to take a crack at it. I love experimenting so this will be fun. |
