Question Receiver Polishing

I have a soft spot for Chilean Mausers.

I am currently in the process of restoring an old Steyr Modelo 1912. The receivers on these rifles were originally "in the white." The receiver I'm working on came with a heavy patina of crud and gunk. Didn't like it, and I wanted to bring it back to its original looking finish. I've cleaned up most of the gunk, with the last step consisting of applying a brush wheel on my bench-top grinder. Did a good job. Looks decent, but has a bit too much luster as compared to the shine of the original finish.

The photo below shows the receiver I'm refinishing on the left, compared to a receiver that has, what I believe, the proper shine or polish to it.

Any ideas on how to go from this luster to a more vibrant shine? Would simple rubbing compound, followed by a car polish, do the trick?

BTT, as I don't think my question was easily viewable:

To me looks like the right has more surface treatment still on it (blackening/bluing) the left has more of an untreated metal color. The finish on the left also looks slightly more course than the right. If this is a "pull out all the stops" project - re-bluing the left and then a VERY light pass with polishing rouge. I'm no expert, in anything

I would say, if there isn't any directional marks from the results of any grinding/sanding, then the use of a buffer with progressively finer grits, to the luster you desire. I would then apply a good automotive paste wax to seal the metals pores to prevent moisture or finger print oils/sweat from starting any oxidation.

Good Luck with your project!

Thanks from Duce

Compound has a super fine grit that I don't think I would use, if anything try the wax that may or may not add some depth and enhance what tone is there.

The receiver itself is not meant to be blued. At least I don't think so. It always remained in the white. Here are some pictures I stole off the interwebs showing what it should be looking like. There is a picture I've seen before of a guy who does these restorations, and they look unbelievable with the white receivers and blued barrels. Can't find that right now, but these are close...

Friend of mine suggested the same thing; however, I don't really know how to do this stuff. For example, what kind of buffer do I use? Where do I get it, along with grit? I really know very little about this.

Try a 'scotch brite' wheel on your polisher.
I restore old bikes and use this to achieve a near factory satin finish on polished aluminum parts. I polish them 'til they shine (no scratches remain) then dull it down with a scotch brite pad manually.
I imagine receiver steel would take forever manually, so try it with whatever rotary tool you used to polish the part.

Polish with very very fine sandpaper. 3 thousand count....5000 count. I've polished my grampas 1950 Ford pickup front bumper with 5000. Works well.

Duce, this may answer some of your questions... as to what is needed...

http://www.brownells.com/GunTech/Bas....htm?lid=10632

Basically you go through finer grits at 45 degree angle from previous grit, to achieve desired luster. You wouldn't necessarily need to use their buffer, it's no different than polishing up a rifle for a Super Bluing job, just not immersing the rifle into the bluing tank.

Thanks from Duce

Be careful to protect the sharp edges of the engravings on the receiver bridge when using a buffer.

Having brightened up a few of these receivers over the years find doing it by hand is "safer" than a electric wheel, Dremel, etc. Go to the Harley shop and ask for some engine case polish, believe it is called Cemi Chrome, and it is similar to what is known as jewelers rouge, metal polish if you will. Fix action in padded vice holder, take strips of very fine emery cloth and use as in polishing shoes, running cloth back and forth. Won't remove any metal but just serves to polish the surface. After you have reached the degree of polish you want, then apply the paste polish mentioned and let it set for a few minutes and then wipe off. You will probably note it turns black and that is the chemical process taking place by letting it sit for a while. Trust me, it will shine very brightly. Not sure if the polished, white receivers were ones issued to the standing Army troops, but have been told these polished ones were used for guard duty at embassies, government buildings, etc. for show purposes?? They are a nice Mauser rifle and many were sporterized and built into high quality sporting/hunting rifles.

Thanks from bigbang and Duce
