There are many rules involved in the 'spacing of gemstones' prior to drilling into the metal. These rules MUST BE FOLLOWED EXACTLY AS SHOWN.
I read a question on Ganoksin a few days ago. "How do I prepare the spacing of holes?" Here are important rules to follow and how to create mini-claws.
=============================================
1) For any reason that you are anticipating setting a fairly large centre diamond DO THAT GEMSTONE SETTING BEFORE YOU ATTEMPT ANY DRILLING OF THE (Smaller) DIAMOND HOLES.
2) The next step is to have that stone set lower than the usual depth, why? You don't want any interference from your 'twist drills' and other round burs interfering with that setting of the large diamond.
3) You need 'complete access' to the placing of the small diamonds.
4) Furthermore if you decide to Milgrain the complete strip of where these smaller diamonds will be situated. THAT IS WHY THE LARGE DIAMOND MUST BE SET LOW.
=============================================
The original writing is still so very important even after I wrote these notes many (15) years ago.
---------------------------------------------------------------------------
Just to reiterate my writings, I'd drop a 'small amount of oil' on the surface of the designated area. I used to use beeswax, but removing the wax was a time-consuming and labour-wasting idea. Our methods do change, agree?
5) Place your stone "Table-side" down onto the metal. Remove one stone, scribe the metal for drilling, and then go to the next stone, until you have all of the 'diamond spots' marked.
6) To repeat, have the distance of each stone be 1/2 the width of each stone. When the holes are finally drilled, that amount of space will be greatly reduced.
7) Please do yourself a great favour and Rouge-Wheel polish all areas before you attempt any gemstone setting. Then afterwards, all you do is a very light buffing...Just enjoy your finished results.
