We all use burs to set gemstones but to make 'creative' patterns is the main reason for this tutorial essay. The tools that we need are just the basic "Bud and Round" shaped burs.
The very small bud-shaped bur (being shown) is measured at #003 (0.03 mm) and this is compared with size #40 (4 mm) in diameter.
I wanted to use this plastic display case, as a reference you have in metal shaping and cutting.
What you are viewing here are silver plates that WERE NOT ALWAYS CUT BY GRAVERS. The following group of display plates were cut into two shapes of burs, these are the "Bud & Round" shaped burs.
There are many times when the 'human hand with the Onglette graver' might not give the correct cutting pattern. It's advisable to use a BUD bur to guide and assist you in this venture.
This 'display plate' shows where the tapered bur is being made ready to eventually make 'beads'. Onglette gravers can only do so much, I always use these selected burs to do the extra carving.
If you see any uneven graver cutting, you can use your tapered BUD bur to facilitate this extra metal cutting. DON'T USE A ROUND BUR, as the Round BUR might and could give you more uneven lines.
I used the smallest available Round bur to clean any remaining metal behind the hand-made burs. What you see here WAS NOT CREATED BY CAD.
Here is the full range of "Bud" shaped burs. These sizes started at #003 and went up to #021.
The "1" designation refers to a ROUND bur, and the "6" is the SQU ordering for a BUD bur.
These are my vast assortment of both "ROUND" as well as the well-used "BUD" shaped burs.
I keep both pin trays full of burs of both 'shapes and widths'. You just never know which bur will be needed at a moment's notice, I'm always prepared for any eventuality.
I keep an extra stock of burs put aside if I need one or two. What I have here are the semi-larger sizes, not only the mini-sizes as shown.
After using my gravers to cut a line, I explored the idea of enhancing the width of the deep cut with a BUD shaped bur.
Extra care was taken as I didn't want any deviations from the Onglette cutting.
As seen in the opening displayed photograph, these Bud-shaped burs come in all sizes and for all uses.
If one bur gets badly worn, it's not always the case to repair it (them) but just discard that worn bur. I could have well over 125+ burs at my disposal at any one time. This does not include the still unused plastic packets.
This is the full set of Round burs from #003 (.003 mm's) going up to #026 (.026mm's).
In closing, I hope that have gained another insight into what these burs can do for you.
