Morion or how we "wild boar" cut

As promised in the theme of the Year 2011 The latest collection, will describe the main stages of the manufacture of stone bowl on a stand.
In this example, the ball is made of a huge crystal morion from Volyn.

Again a lot of pictures, let you know how to finish





Let's start

Head 1st.

Initially, it was:
Axe, naturally more useful

For this we need:

most big "Bulgarian»



and diamond blade for cutting stone



Putting "Bulgarian" with the disc, and forward - cut off everything that does not fit into a cube.
such is ...



... And it



and so until then, until you get something resembling a "cube»



Now cutting corners until you get something like this:



Healthy, damn it, we got!



Now - a little break



And my favorite - saw))
ps .: blank bigger than my head!



4th Chapter.

Further, our goal, consistently (though it is possible and chaotic, it's like someone like that) to cut all that distinguishes this piece from the ball.

To begin with, for example, all the angles.
like this,



so,



And so



It should get something like this



but not resting on our laurels, we continue to cut all unnecessary



and gradually become something like ...

REMEMBER !!! The better you will cut it - the easier it will be to grind on.

EPILOGUE

But this is not the end, rather - is just the beginning. Now it is a long and tedious grind. After that - lapping and polishing.

P.S. The fact that it would cut my left one day.



Actually the most difficult and important is behind us, now long and careful process of its powders.

Let's start:

For this we need:
metal crown,



abrasive powder,



and harvesting of the ball.



We combine all this and for a long time on this spinning ball crown with powder ...



After some 10-15 hours (depends on the experience and stamina) you come to the final
fade out all gashes and chipped



But this stone ... there is always room for surprises ...
For example, this time put out a piece of crystal.



depth of 1, 5 - 2 mm.
It's only 6-8 hours of extra work)))



But there comes a time when it and behind.

Ball trate and can be measured.
We've got 185 mm instead of the original 195. Not the worst result!
Well, continue?
We continue using all sharpens finer abrasive
sharpen ball



and constantly seeking a uniform haze on the entire surface.
about how it should look



So far so good.
This means that it is time for the General fitting
Well into place, and how it looks to me like the whole



But before the end is still far.
To be handling all the finer abrasives
It's enough



Now polish !!!

That's all. Bowl on stand ready !!!



The whole process took us:

Cut 1 day;
Vytachivanie 3 days;
Lapping 1 day;
Polishing and manufacture of stand 1 day.

TOTAL: 6 days of intensive work.
