Instead of highjacking the 'show n tell' thread I've started this hoping to work out a few of the bugs in my cutting.
I guess the big one is transfering after cutting the pavilion.
I take my time.
I line everything up.
Then I pushing it all together thinking I have it perfect. (At this stage it is now covering the joint with epoxy too.)
But, it's far from perfect and it's not until I'm part way through cutting the crown that I realise this fact.
The 2nd biggest bug is over cutting.
My machine doesn't have any digital help. So I'm just setting the height and going for it.
But after one full revolution of the stone the ones at index 64 and 32 are always under cut, so I cut deeper, only to find I've cut through too far and into the girdle.
Am I just too heavy handed at times? Should I need to put extra pressure on the quill at all?
The 3rd one really got to me. The window.
I've watched countless videos on how to do it but there is something wrong at my end.
Just when I think I have it cut right, I change to a pre polish disc only to find the height is different because of the difference in thickness of the two discs. And my final polishing disc is even thicker.
I thought so long as the cut was correct, then the other steps would be at the same setting only at a different height due to disc thickness. Like a drill press.
But every time I change discs, I have to adjust the angle again.
Is it the tower out of line? Or am I missing something else.
I've had fantastic feedback from this forum so far so I'm hopeful I'll get the right advice again here. It could be ongoing the way things are going.
Just for good measure I'm starting on a stone that should take me a couple of weeks to do. I've got a few pieces of sapphire sitting there itching to be cut so I'm going to give one a go. I'll be ordering the diamond 50,000 for the polish as Dihusky has advised.
It's only small. 10mm x 13mm and 10mm thick. That should fill in the time while I'm waiting for my previous stones to come off the dops in the nail polish remover.
Any suggestions on the cut?
