Russ's tool making article..

W.C. Turner

>I'd like to try making some tools. I'll admit, right off the bat, I'm igornant about types of steel to use for tool making, & how to do it.

1)In the Enco catalog I found O-1 drill rod, but, no mention of O-2.(master catalog, pg.657) Did I overlook it?

2) What is the difference in O-1, & O-2 drill rod?

3) On pg.657, it shows that air hardening drill rod is more expensive than oil, or water hardening d-rod. Russ had mentioned that water hardening "W-type" steels are considerably more expensive. I don't know if the W-1 on pg. 657, is the same Russ mentions or not?

4) Can somebody explain why the water hardening drill rod presents more of a hazard for burns than the oil rod?? Does the hot steel cause the water to explode on you?

Thanks,

W.C.

>O2 has a higher carbon content and that means it will get a little harder than O1. Use the O1 if that all that is available. There isn't enough difference to worry about.

There is nothing wrong with the Water Hardening tool steels other than sticking a red hot piece of steel into cold water can be a "religious experience", especially in a small container of water.
