Cast Iron Cam Query

[Troutsqueezer]

Hey Guys,

I'm about to make a simple cam for my hit and miss Upshur. I don't have steel rod handy in the right size but do have a nice piece of cast iron rod .75" dia. which is perfect. Anybody know if cast iron is a suitable material for a single lobe cam such as this? Seems like I could almost make this one out of Delrin and have it work (for a while).

all the full size hit and miss engines use cast iron for there cams and cam gears.
they work very well.
