Spanish Model 93 Mauser 7x57 7mm Build Part 5 - Jeweling Bolt, Modifying Shroud


1 of 5

Jeweling the Extractor
Jeweling is a great way to beautify an unsightly object.

Pitting and other signs of age and abuse made the bolt look pretty rough. I decided to try my hand at jeweling, to hide the ugly and make it look better. I tried it on the extractor first, and was very pleased with the results.

Very early in my Spanish 1893 Mauser Project, I decided to try some jeweling to hide some ugliness. It worked out very well, and I was so pleased that I eventually jeweled most of the bolt.

Jeweling is pretty simple; it's just a series of overlapping circular polish marks. These swirls catch light and do a great job of hiding flaws, while looking pretty good to boot.

In my case, I didn't use anything fancy... just a flexible abrasive rubber tip originally designed for use in a Dremel type rotary tool. It was round, with a nice flat tip. I put a drill chuck in my mill and chucked the rubber bit in it.

I picked a starting point and brought the abrasive down against the steel (kind of like operating a drill press), creating a round polish mark. Then I raised the abrasive and used the mill's cross slide to move the bolt a small amount (somewhat less than the diameter of the polishing tip) before repeating the process. I kept track of how many cranks of the cross slide handle I made, to make it easy to uniformly space the polish marks.

As you can imagine, jeweling takes a fair amount of time and patience.

You don't need a mill to do this job. I'm sure it could even be done (very carefully) with a hand-held drill or Dremel, but a drill press would be a great boon and isn't all that hard to come by.
