They pressed flawlessly.




They fit nice. They only had a couple of tiny bubbles. The margins were closed to 10x mag.
They really have to fit perfectly with out adjustments because you cant be grinding on the inside of thin pressings.

Any short areas you can add on later later.


I thinned them down to .4 over the entire surface with a true turning green stone.

I take it thinner though at the margin just short of the edge of the margin.
Then I use a diamond impregnated rubber wheel to make the marginal edge flush with the die so I dont feel any catch.
