I think you can use 4140 and hardened. What machine do you use to cut the rack ? What kind of precision? I knew somebody cutting rack for doors.

I am gonna cut the racks on a Kearney and trecker horizontal mill. I am by no means a machinist, a coworker is gonna help me set the machine up when I go to cut them!
