I am still having a problem understanding you, sorry ?
Your coin picture looks like it has a raised silver inlay that is still lacking sculpture and detail.
Am I misinterpreting your picture. ?
If I'm correct, when this is finished it would give the impression of a figure raised above the known...
Are we talking about steel/iron pieces inlaid over steel ? Or gold over gold ?
Or are we talking about inlaying dissimilar metals ie. gold over steel or gold over silver etc.?
Dissimilar metals are usually added for contrast and similar metals for dimension and drama.
Paul, you can buy various length bar clamps to hold different barrel lengths from Harbor Freight for a few $$$.
With some simple modifications and a vise they will hold round things between centers.
When I was teaching the NRA Engraving classes at Lassen and Trinidad colleges there must have been about a dozen students who used a lathe chuck.
Worked well for them doing flat work and some round work can be held between centers on a modified bar clamp.
I use a modified bar clamp held in...
Paps, It's hard to see with the reflections.
Maybe try another photo, but first rub the cylinder with modeling clay or transfer wax and a very light dusting with powder to break up the reflection.
To add to the misery, watch band links and parts a usually formed by machine stamping which also adds to their surface tension and hardness. And being thin, hard metal they tend to vibrate away from the impact of the graver and increase the graver point breakage.
Not the most fun things to cut.
I am not following you.
"Blue Remover" will remove the blue.
You can neutralize it with plenty of water or with water and baking soda.
When the side is bare steel and dry and warm you can French Gray it using a phosphoric acid based ceramic tile cleaning solution.

Hello Erik,
I'm located in California too. May I suggest you add your general location (such as California)
to your bio. It is helpful to giving you general advise on tool suppliers etc.
For you project you might consider starting out with an Onglette size #1.#022-626 from GRS if you don't have...
I would start with one about 1mm. thick.
And sharpen the face to 45 or 50 degrees, depending on the hardness of what you are cutting.
Create a lift/clearance/belly of 15 degrees on the bottom and both sides extending from the point to the back of the graver.
You can switch to a thicker onglette...
