Another question…..what kind of file are you using on the inlay? Can’t be a normal file can it? Almost anything is hard enough to cut gold, but where’s the line that you don’t scratch steel?

It’s a #3 Grobet file made in Switzerland. I use the #3 on the gold. When I start coming in contact with the steel I switch to a finer #4. The scratch lines I make in the steel with the #4 are very fine. Fine enough that I can go over them with 600 grit paper and they disappear.

I started on the fourth flat this morning. It’s all undercut but I ran out of gold wire. I have more ordered and it should be here Tues. Mon if I’m real lucky. I ordered 12” of 24 ga. I’ll pull that through my draw plate and I’ll end up with around 30” of smaller dia. My draw plate is metric and I’ll end with .35mm wire for the rest of the inlays. It’s more economical to buy larger dia and draw it yourself. The 12” of 24 ga 24K gold wire cost $264. That’s $22/in. I’m hoping that will be enough to finish the job.

I rec’d my wire. The first thing you have to do is anneal it with an alcohol lamp.

Next, the end of the wire has to be sanded to a point so it will start through the die. After every draw, it has to be annealed and repointed. Then you can pull it through the next die.

The wire comes in US wire size. This was 24ga or .020. My drawplate is made in Germany and is metric. For the inlays on this gun I draw to .35mm. Going to school in Italy, I was forced to learn metric. I still use metric for all of my layouts. Here’s the wire ready to use. It’s annealed and very soft.

I finished up the 4th flat and hope to finish the final one today. Then I’ll go back and touch up everything. I’ll be glad to finish the repetitive cylinder.
