Lewis turned me on to a (new to me) mould material that I have not used before, a lot of the mould makers use this stuff. It is 65-45-12 ductile iron. I have always used either aluminum or just gray cast iron. It was about $65 for a 3 foot bar of this stuff shipped to Utah from Wisconsin. Enough to cut about 20 moulds.
I gotta say, if it machines in the lathe, as well as it cuts in the mill, I’m gonna just pitch all my gray cast iron into the trash.
The mill doesn’t act like it even knows anything is in there.
Gotta set of blocks ready for vents and locating pins. I think I’m gonna cut about a 450 grain .453-.454 bullet. Probably the one I posted in “Question for Machinists” only take the bottom land off so it ends up about 450 grains instead of 500...
Great stuff so far.
I’ll post pics as we go.
Thanks Lewis! This stuff seems better than sliced bread!
