I'm a novice, so please excuse the dumb questions that are sure to follow.
I am a broadhead maker, and until now I have used a commercial heat treater to treat my blades.
At the moment I am setting up my work shop for heat treating, and need some advice.
The small blades I do are 1055 steel at 1.2 mm thick.
My first question is at what temperature and for how long should I do them in my kiln.
I would prefer to keep scale to a minimum if possible.
The second question is what type of quenching oil.
I would prefer to use a Castrol mineral oil, as there is a Castrol distributor close by.
Can anyone recommend a Castrol oil type.
What temperature should I hold the quenching oil at to help the quenching.
My thinking is to have a 44 gallon drum of oil right next to the kiln for a fast transition from kiln to quench.
finally, what temperature would be a fair starting point to run my toaster oven at, for tempering.
I am aiming for a Rockwell hardness of 50 to 54, and have access to a tester to check the finished result.
