Can anyone give a quick primer/recommendations on hardening and then tempering O1 steel? I’ll give you what I plan and would appreciate any feedback/hints you can offer.
I have a piece of 1/8th” O1 steel 2”x3”. It was purchased annealed and now I want to harden and then temper it to serve as a plane blade (kind of). I have the following steps in mind:
1. Rough shape the bevel.
2. Place on a ‘heat brick’ and use a MAPP torch to heat to a uniform ‘cherry red’. I would use something like this. http://www.lowes.com/pd_34454-215-600448___I would try and heat the blade uniformly and slowly to the desired color.
3. Immediately quench in some kind of oil (I would probably use vegetable oil or motor oil- does it matter)
4. Once cooled, heat in an oven set at 300 F for about 2 hours to anneal.
5. Reflatten and hone the bevel.
Does this sound about right?
Thanks
Pedro
