Hi, everyone! Here's my first cab, together with the story of how I've made it. This is not intended to be a tutorial, I'm only describing my "technology" with the hope that the master cabbers here will read it and correct my mistakes.
Please be welcome to critique anything you don't like at this cab, sincere opinions are very welcome.
So, a few days ago I've bought a small Brazilian slab. I chose an eye-catching pattern in it, which also included a druzy. I've cut it as you see in the first pic.
(KD, have a look in the background
)
I used a crayon as a dop stick and I used super glue to bond them.
I don't think it was a very good idea, because the crayon went off during washing the cab after the 400 grinding, but I still was able to finish the cab holding it in hand. I think the diameter of the dop sticks might be bigger, and also metal sticks will improve the binding.
So, after grinding it till I almost reached the contour, I marked a line on the slab's thickness.
I did this for helping me to keep the area below the line vertical. Then I started from that line upward with a steep slope. After that, from the middle of that slope i started another slope at about 45 degrees inclination. Then I grinded the corners of the triangle with a very smooth slope, till just a small circle of about 1 cm remained untouched around the drusy area. Then I filleted all these slopes, removing the edges.
All that I described till now was made on the diamond resin disks.
Next I started using my polishing flexible pads: 400 which rounded remaining undesired edges, then 800, 1500 and finally 3000.
The result is right here:
And backlight:
I would like to clean that druzy. In normal light it seems clean but in the backlight one can see it's not. Any advices in this problem?
Thank you for looking and for any comments and advices.
