I have a project for which I would like to use some excess Thomson linear shafting. I'm pretty sure it is 1566 which is basically 1070 with a bit of Mn (the shafting is etched with the Thomson logo and sparks out like 1070). It will involve annealing, machining and then harden/temper. But I can only find very limited reference to machinability and hardening information for 1566 on my web searches. The two references I found are very sketchy and somewhat contradictory on the hardening temperature. I don't have any good heat treatment texts and my copy of MH is of no help in this case.
Does anyone know sources for what to expect during machining (simple turning of 3/8" to 3/4" dia, drilling and tapping)? What is the recommended hardening temp and quenching medium?
These are non-critical parts that I will personally use in the shop for tool and work holding. I know that I could buy new steel but I strongly prefer to use existing stock that I otherwise have no use.
Thanks,
Jim
