Today, I made my first spinn-casting with zinc.
It was just a first test shot to see what I can do wrong and what I did
already do wrong.
So the mold was just a plaster mold [1] and the zinc was just some scrap
zink sheet metal for roofing. That zinc proofed to be good enough and I
will use up all the rest before going to the costy zinc I ordered.
At least, the spin caster was a success. I had no other motor at hand,
so the disk is rotating with nearly 1400 RPM. Direct driven! The disk
has a diameter of 12". I thought more g-force = better surface.
334 G's!
