    Mark and Sandy, this is exactly the helpful sort of info I was hoping people would contribute to this thread. Thanks so much for bothering. Hopefully the next person to have a go will read this first and learn what not to do 😉

    Mark, when you say better off regarding the oil container, are you talking from a safety aspect only or will this have impacted on the quality of the hardening process? I’ve got an old coffee tin that’ll hold about 1.5 litres of oil that I was thinking of using next time. It’s about 5″ across. Will that do?

    Before this gets too far ahead of everyone, we will be hardening shortly, but remember you do not have to harden the steel for it to work for your seat. It will most likely carve out the seat fine but needed a couple of more sharpenings during the process.


    Sorry Paul, I’v worked as a machinist/toolmaker most of my life and am an Engineer in metallurgy. I get a little carried away with the technical stuff some times.. I’ve done rustic Heat Treating using many techniques with some pretty good results. It’s going to be fun to learn the techniques that you pass along. I look forward to seeing those videos.
