    Sure, preheat-treated 4140 (30-35 rc) and nitride it when you're done machining would be best.

    If you're a hobby machinist, cold rolled soft, should last a lifetime but you could have them case hardened.

    Our mentor, Rudy K. just discribed making some in HSM.

    I have a QC toolpost photos I made for an old Unamat and one for a 13 x 40 lathe, that I'll try to get posted sonewhere.
    It has no dovetails, or other fancy machining required.

    It onlr requires a keyway, couple thru slots,
    and v slots in the blocks.

      Paul Ernest,
      Have a look at:-
      http://www.metalwebnews.com/howto/to.../toolpost.html
      There are instruction on there about building one. I may be just a weenie but biast as I wrote it but it does work and works well.
      By the way BDMS is UK speak for Bright Drawn Mild Steel, what the US know as cold rolled.

        John's QC post is well worth the look.
