Aonexander - as GWIZ advised, read the FAQ.

We do not use embedded images or off-site hosting and we especially do not use Photobucket.
The FAQ will tell you why.

Welcome on board A1ender.
Beautiful work you got going on.
I sometimes wish I had more time and patience to work with wood.
I love those homemade planes you posted pictures of.

Thank you CEC,

I wish I had the patience to work with metal.

You got any other suggestions for a quick and dirty way to harden O1?

Here's an article that describes one way of doing it:

And another:

A book I can recommend is The Complete Modern Blacksmith by Alexander Weygers. He was a talented fellow: http://en.wikipedia.org/wiki/Alexander_Weygers

Welcome A1exander,

For relatively small strips of steel I have used a simple Mapp torch and a Tempilstik...........see link below.

The sticks appear to be fairly accurate and are real easy to use. Even though the link I attached will let you purchase directly from the maker, some larger welding supply places also carry them. They have 1500F (816C) and up to 2000F. I think I paid about $8.00 for the last one I bought.

o1 is easy to heat treat It has a very high carbon content and gets screaming hard out of the quench. (oil) Bring the steel to non magnetic (1550 f) and quench in oil. ATF or vegetable oil will work well. At this point the steel is very hard and brittle. You need to temper it by placing it in an oven for two hours at 475 F.

Its a great steel and its cheap. Enco is a great source for precision flat ground. Its only drawback is its prone to corrosion.

Tons of info on the web, like this:

Hardening
Preheat thoroughly at 1200ºF then heat to 1450ºF to 1500ºF depending on section size. Hold until uniformly heated through. Quench in warm thin quenching oil to about 125ºF and temper immediately.

Temper For One Hour
300ºF -------------------------C 63-64
400ºF -------------------------C 61-62
500ºF -------------------------C 58-60
600ºF -------------------------C 54-56

An infrared thermometer is the easiest way to gage the temp, but not every IRT will read to 1500°F (none of the inexpensive ones that I know of). Color temp is the only way to do this without either an IRT or without a heat treating oven.

A good article here that touches most of the basics: Heat Treatment of Tool Steels.
