Rather than buy castings for certain projects, especially the simpler
tooing type stuff, I thought I'd just buy cast iron bars / blocks and
work with that. It's not just a matter of being tight, but in part a
wish to modify designs or do something from scratch without trying to
get a one off casting made and needing paternmaking and all all that.
However, looking at mkmetals website, it seems that it's quite an
expensive raw material eg 50mm diameter by 1m costing a hundred quid. I
could believe postage might be lot but isn't this the basic stuff that
comes out of the furnace at =A350 a ton, before it gets made into the
fancy stuff like steel? Or is mkmetals selling a particularly exotic
kind of cast iron ?
I'm after small bits eg suitable for making a George Thomasish
pillartool, or for the body of a (woodworking) block plane. Another
thought was a bigger slab to cut some T-slots into for a milling table
for the lathe. At this sort of cost I could buy a full-blown mill
cheaper than the iron.
Any thoughts or suggestions ?
