I basically use a sharp scribe to do as you do, but add just a tiny little flip upwards as I remove the point to remove a tiny bit of the metal. As i go along I will scrape a fingernail over the work to remove burrs.
Great work...especially the eyes!
There was an engraver who came to the Vegas shows several times who had the problem of acidic hands. As I remember it, there is a soap that can help with the problem but I do not remember anything else about it.
Just a thought...acidic oil from hands can cause a problem like yours. I engrave on a steel gun part sometimes for months without any rust problem. Even when I lived on Kodiak Island which is a very salty air location.
A small correction for John B. The Engraver is a quarterly publication, not a monthly one. Wish it was monthly but it is a huge amount of work for the editor as is!
That is steep for soft metal which I seldom cut. I do use 45 degrees on aluminum which I have used for guitar/uke inlays and some car parts. The vast majority of my cutting is on gun steel.
I use a 90 degree carbide tool for all my scroll cutting and most everything else. My depth of cut for most work is in the range of .003 to .005" with sculpted work going to maybe .015". It all depends on the design needs...something you will develop with experience. I use a face angle of 57...
Whatever works for you. I tape a piece of clear acetate over the area then scribe in some scroll intersections for indexing then scribe in the outline of the animals. This way I can see the excess gold and everything else very easily.
The transfer I use to originally locate an animal does not have indexing to use again for the gold. I doubt that by the time I redraw, cut and add teeth that the outline would be accurate enough so I make a new indexed overlay.
At this stage I make an acetate overlay indexed on the scroll pattern and then outline the animals so that when the gold is set I can find the outline of the animal and know where to trim the gold.
Ditto Marty's comments. I always try to get the action facing towards the muzzle. Also as Marty says, there are occasional exceptions but I always try to keep the action forward.
I use a flat toothpick to put a small dab of wax (unheated) on some wax paper then dip the end of the toothpick into the lampblack. Then stir the lampblack into the wax and use. It does not take much lampblack to make the wax black. This will darken cuts and heko bring out detail without...
I have had great success with the Renaissance wax and lamp black. I use the lamp black because it does not add anything but the fine lamp black. Then I put a few clear coats of wax over the tinted coats.
