I always thought that meehanite was just a process, not anything
different from ordinary cast iron. Nodular cast iron is also
quite good. My concern with cast iron is to obtain it in square,
round, rectangular, and round-cored. I've bought all these
shapes which are provided continuously cast by Wells Mfg. Co. If
you have the capability of casting iron yourself (or work in a
foundry like I used to), you can certainly try to get/make
something special. But generally a large volume of material is
needed to make a specialty casting melt worthwhile. Thus, I opt
for the off-the-shelf availability which covers much of my
needs. This is why I mentioned Dura Bar as a possibility.
http://www.dura-bar.com/index.cfm and why I mentioned Metal Mart
as a supplier of some of the Dura Bar products
http://www.metalmart.com/

The reasoning behind this comes from the hobbyist point of view,
where we don't need a large amount of stuff but frequently want
something of known quality with no-place to get it... Once you
begin to specify particulars, the price goes out of sight for
small quantities.
