pneumatic diamond engraver

Gemsset · Jun 11, 2008

Hi,

Does anyone has experience with the pneumatic diamond engraver?

can we engrave with it or is it limited to hammering?

Thx

I haven't used that particular tool, but if you use any type of power assisted engraver (gravermax, Lindsay, etc..) it's very easy to make your own diamond point tool. Just set a .005ct diamond upside down in a piece of soft steel rod and then temper it.

Gemsset, it doesn't look like it would be able to engrave except for maybe stipple lines or backgrounds, etc. It you have any other pneumatic engraver you could do the stipple with a carbide or steel point, or make the diamond tool that mbroder suggested. I don't think it would be a viable substitute for engraving, but I haven't tried it either. Good luck.

(Not to pirate the thread or get off the topic, but I am curious.)
Mark, how do the diamonds in the gravers hold up, are the points prone to fracturing? I use carbide for stippling background and they stay sharp but they do tend to chip off once in a while, so I am wondering if the diamond tips could be a better way to go or if simply sticking with the carbide is better?

Hi Brian

I don't stipple all that often, but I've only had to replace the diamond once in the last 10 years. I don't work in steel though, only gold, platinum and silver.

interesting replies, thank you all for those.

I am working with the Gravermax so maybe I make something myself.

Gemsset;
If you look on page #10 in the GRS catalog, item #002-123. They list a diamond point stipple tool.

I've made a couple diamond tip tools for stippling. It tried using them on the background of a Ruger stainless that was miserably hard. The diamonds didn't hold up well at all. For soft metals they last a very long time.

most of that diamond mtl that is retailed to us is probably industrial diamond, not gem stuff. i personally don't see any advantage of diamond over the other available points, either store-bought or home brew. unless you're workin on a rocket engine. jm2cw
