I’ve been considering building my own vacuume caster, and an
interesting thought struck me. I was under the impression that
the presence of oxygen during the casting process is a potential
problem sometimes. Well, it also occurs to me that argon is
quite a bit heavier than air, and is readily available from any
welding gas supplier. So, it should be fairly easy to build a
"box" around the casting part, fill and fill it with argon.
Yea, the vacuume would suck down some, but it is 15$ for around,
150Cft. So who cares if we loose some?
Anyone have thoughts on this? Is this worth doing, or is the
danger from atmospheric O2 minimal?
