  • more on cast iron vs. steel

    i have another question regarding the substitution of steel for things i normally see made of cast iron. i need a steady rest for my 11" SB lathe. i rarely see them for sale, and they seem to go on the upside of $150 if they do show up. i also have access to all kinds of steel. if i made a steady rest out of steel, would it be okay, or is cast iron recommended for some reason?

    Steel is fine for this, I have made a couple by welding. I used a piece of extra heavy pipe for one.
    Cast iron is used more for convenience of manufacture than any structural reason.

        Steel should work.
        Cast Iron absorbs vibration much better and is a major reason besides lower cost (castings)to make it. can't make a tuning fork out of CI...
