I'm also unfamiliar with 1040, although I've heard of it. Here are some characteristics of 1040:
Principal Design Features - 1040 steel has a higher (0.40%) carbon content for greater strength than the lower carbon alloys. It is hardenable by heat treatment, quench and tempering to develop 150 to 250 ksi tensile strength.
Applications - Used for crankshafts, couplings and cold headed parts.
Machinability - Machinability is good, rated at 60% that of the 1112 alloy used as a 100% machining rated steel.
Sounds like a good choice to me.
