Default Glass Bead Media Testing on 5906 Frame

Here are the results of some media testing I did on a junk 5906 frame (5906 Abuse (Cracked Frame)).

Media Tested:
Ballotini: 170-325 grit, #13 glass beads (GB) purchased from Grainger
Pro-Blast: 80-120 grit, #9 glass beads (GB) purchased from ebay (seller: tacomacompany)
Baking Soda: Arm & Hammer
Central Pneumatic: White Aluminum Oxide (WAO) 220 grit purchased from Harbor Freight (It looks like Harbor Freight has discontinued the 220 grit WAO; this outfit seems to have small quantities at reasonable prices: Panadyne Abrasives)

Note: Media blends are by volume not weight.

Equipment: Speed Blaster gravity fed blaster running at 70psi (except as noted)

PPE: Goggles, respirator, 7mil nitrile gloves, bandana to cover head, ear muffs to cover ears, mechanics one piece suit – I’m blasting outside, not in a booth.


Testing Round One (R1):

Picture #1: in the middle of the trigger guard you can see four finishes coming together. The top left is #9GB only, the bottom left is #9GB + soda, the top right is #13GB only, and the bottom left is #13GB + soda.




Picture #2: left is #9GB, middle is original, right is #13GB




Picture #3: left is #13GB + soda, middle is original + soda, right is #9GB + soda




Picture #4: inside the trigger guard there is a faint line in the middle, the original finish is on top and the original finish + soda is on the bottom.




My impressions on the first round of testing – the #13GB cleaned up the frame much fastener than the #9GB, but the #13GB media left a slightly brighter finish. The soda did a good job at cleaning, but did not remove any of the scratches. When I was blasting with the soda it looked like it was darkening the frame, but after I cleaned it off, the finish in the soda blasted areas was a little lighter.


Testing Round Two:

Picture #5: left is R1 #13GB, upper side of dust cover is a 1:1 WAO/#13GB blend, lower side of dust cover is #13GB at 100psi.




Picture #6: left is R1 #9GB, middle left is 1:4 WAO/#13GB blend, middle is original, middle right is R1 #13GB, right is 1:1 WAO/#13GB blend.




Picture #7: left is #13GB at 100psi, middle left is R1 #13GB + soda, middle is original + soda, middle right is #13GB at 110psi, right is R1 #9GB + soda.




Picture #8: left is R1 #9GB, right is 1:/9 WAO/#13GB blend at 60psi.




Picture #9: 1006 blasted with 1:10 WAO/#13GB blend at 60psi. The sight recess was masked and retains the original finish, the surrounding areas were blasted.






Picture #10: 1006 blasted with 1:10 WAO/#13GB blend at 60psi. The middle recess of the back strap was masked and retains the original finish, the surrounding areas were blasted.




My impressions on the second round of testing – glass beads at higher pressure do provide a flatter finish than lower pressure settings, but the finish is still lighter than the original. Adding aluminum oxide does dramatically change the finish color/brightness. The first blend of 1:1 was surprisingly dark, even the second blend at 1:4 was very dark, but the third blend at 1:9 with lower pressure was very close. It was a little darker when compared to the original finish on the 5906, but when I compared it to the original finish under the grip of a 1006 it was near perfect. I altered the ratio one more time and blasted the 1006 with a 1:10 ratio (5 tsp of WAO per 1 cup of #13GB @60psi); it turned out excellent.


Final Comparison Photos:

The following pictures show the blasted 1006 with some of its brethren that still wear their original finish. I took the photos with and without flash to show the finish in different lighting. The top pistol is a 4506-1, the middle is the blasted 1006, and the bottom is an original 1006.














The only difference I can find is that the blasted 1006 does not feel as smooth as the other two, but this could be because the finish is brand new and the other two have smoothed out over 20+ years.



Here is an bonus picture showing a comparison of WAO grit I used on a project 645 awhile back (645 before and after)

Media Tested:
Abrasive Armory: White Aluminum Oxide 120 grit purchased from ebay (seller: theabrasivearmory)
Central Pneumatic: White Aluminum Oxide 220 grit purchased from Harbor Freight

Picture #11: the knife is 120 grit, the saw blade is 220 grit



I also picked up another 645 recently and had a little refinishing fun (645 Refinishing Fun).

skjos - Great info and pictures - Thank-you! I had heard about baking soda being used but had never seen the results. These post is a keeper for me ...

Edited to ad: have you had any problems with the trigger play spring or it's rivet during/after re-finishing 3rd Gen's? Understand this was a junk frame so you may not have messed with it.

I'm gonna ask the really stupid question here.

The baking soda: are you saying that you mix the baking soda with the beads, and then apply that combination using the blaster, or are you saying you blast with the beads and then follow up by cleaning with the soda by itself by hand?

I've never bead blasted anything, so I don't know anything about the soda component. Guess I'm wondering if the soda by itself on a rag, for instance, is a cleaning agent in its own right.

I blasted with the glass beads first, then with the soda. The soda was applied with the blaster at the same 70psi setting.

I understand the factory used a blend, aluminum oxide & glass beads. No idea of the mesh size or mix ratios though.

Cheers

What media best replicates the factory finish? I have a project that will need a bead blast when done. Thanks

Both the #9 and #13 are brighter/shiner than the factory finish. If I can find the time in the next few weeks, I'll try blending #13 and 220 grit aluminum oxide and see what happens.

Whatever you use (abrasive paper of media blasting), it will be a good idea to dip everything into a citric acid solution as a final step to passivate the SS surface. The citric acid removes any free iron on the surface and makes it more corrosion-resistant. Many super markets sell a product called "Lemi-Shine" which is a powder used in kitchen dish washers to remove streaks on glassware. It is nearly pure citric acid. Citric acid solution is also good for cleaning brass cartridge cases. And it's not hazardous like nitric acid would be.

Baking soda (sodium bicarbonate) blasting is most often used for removing softer materials from metal, such as paint. I am surprised it would be abrasive enough to have much effect on SS.

I've updated the original post with my second round of testing. BMCM was correct in that the finish is best replicated with a WAO/GB blend. More specifically, 1 part White Aluminum Oxide 220grit mixed with 10 parts #13 glass beads (5tsp of WAO to 1cup #13GB) run at a lower pressure 60psi.

I may test passivating the 5906 frame with citric acid, but I'll need to do a little more research into temperatures, time, solution ratios, etc.

Thank you for the doing all this testing. The information you've compiled is quite valuable. My current blasting setup is loaded with 270+ beads. I do need something with more tooth to replicate the factory finish after I've done a bunch of metal work. I've been meaning to set up another small cabinet with a blended abrasive media and what you've done here will certainly guide my choice of media.

By the way, not sure if you are aware, but stainless steel once cleaned will passivate by itself merely through exposure over time to atmospheric oxygen. In a week or two the protective layer of chromium oxides will form and the steel will be every bit as passive had it gone through a brief nitric acid bath.

Cheers
Bill

I've been using crushed walnut shell 25# packs from Harbor Frieght...
but the GB looks more like what I want...

Although, from the pics, could barely tell any diff from #9 to #13...

There is not much of a difference between #9 and #13, both are brighter than the factory finish, but #13 is a skosh lighter than #9. Also #13 removes surface scratches faster than #9 due to more media striking the part.

skjos: You undertook a tremendous amount of work (hassle) which has now provided this forum with valuable information. It deserves every one of the stars now appended to your post.

It'll benefit a lot of folks - me being among them as I've wondered time and again, "What kind of media?"

And who would've imagined the aluminium oxide having such a pronounced contrast range?

You've spared me a huge amount of work and, more importantly, a screw-up, followed by another, and another, and . . .

Thank you, Sir!

I'm glad to help out; I hope members will post their results to this thread when they give the 1:10 220WAO/#13GB formulation a go.

I finally got around to cleaning out my cabinet and changing the blast media to something with more "tooth" and Skjos's thread here seemed the obvious place to share my results.

I had been using some 270+ straight glass beads from Brownells. While that stuff was adequate for cleaning and some removal of light tool marks it would not replicate the original blast profile that S&W did.

Today I loaded my cabinet with the #4 Econo blend from Mcmaster-Carr
McMaster-Carr
This media is a blend of aluminum oxide & glass beads of 120-170 mesh size.

Today I ran some parts through using that media at around 80psi and keeping the nozzle 4-6 inches from the workpiece.

I'm very pleased with the results....

Here on the left is a 4513 just blasted next to a unmolested 4516-2 slide. Near as I can tell the surface profile is identical between the two, just a little brighter on the 4513.


Here is a 1066 slide that had a horrid dremel hack job done to it. It's been welded, ground, milled, filed & sanded. There's no evidence that anything was ever done and the finish is blended perfectly.


If anything I may back off on the air pressure a bit for the next run. In any event, I can't complain a bit with these results.

Cheers
Bill

Insofar as my eye is concerned respecting the two side-by-side slides, the "lighter" difference could be fully attributable to lighting - as in that light which existed when the image exposure was undertaken.

Absent of my ability to get really, really close to each of the two slides, the grain of each mimics the other in the supplied images.

Furthermore, it's reassuring to see what a, um, "revised" slide reveals after getting beaded: nothing but a nice-looking finish.

Thank you for posting your results.

Later.

Thanks to everyone for this very informative post.

Pardon a bit of thread drift, but has anyone tried blasting a slide or frame without a detail strip? Especially when not bead blasting the entire weapon, is it possible to remove the blasting media with a pressure washing? What about masking parts such as sights?

Seems like a detailed teardown and reassembly is considerably more work than the actual blasting and I wonder if there are any shortcuts.

Nope and I wouldn't even try. You see, that fine blasting media migrates into everything. And I mean everthing! Even parts you've carefully masked off with heavy vinyl tape and are not directly blasted, you'll find grit under the masking when you peel it off. Imagine trying to clean grit out of areas like the firing pin channel, under the extractor or in the recesses under the rear sight without disassembling

Another consideration is fully degreasing the parts before you blast. If using a blast cabinet where you're recycling your media you don't want any grease or oil contamination in there. It'll cause clumping in the media and any parts that are destined for coating ie. Cerakoat, will also have surface oil contamination. No good for getting paint to stick.

The only way to do a proper & thorough job is detail strip the parts. A frame nearly falls apart, only the sear spring requires a bit of careful work. Slides are a bit more difficult. Getting the sights off can be troublesome and the extractor pin can be disagreeable at times

Even when stripped, getting all the grit out of all the nooks & crannies takes some work. I'll go over the parts with compressed air first then wash with detergent, rinse then back to compressed air. And after all that, occasionally I find a blotchy spot or a small area I missed entirely and have to start all over again

Back in the day I often told my lads "Do it right the first time or not at all" Any job done halfassed will eventually have to be redone. So in short...Blast some assembled pistol stuff and you'll eventually wind up detail stripping anyway to get all the grit outa there. Sorry, no there's shortcuts

Cheers
Bill

Great job Bill, do you know what ratio the McMaster Carr media was blended at? I'm curious if it is near the 1:10 ratio that I found was the sweet spot.

As far as stripping the frame and slide, I remove everything except the front sight (does not affect function), barrel bushing (non-removable part), and the sear spring (pin is destroyed during removal). I mask the heck out of these parts and clean them thoroughly after blasting (Rinse, 90psi air blast, rinse with tooth brush scrub and foam tipped swabs, 90psi air blast, and then a detailed final q-tip cleaning).

No idea as to the ratio though. Out of curiosity I contacted McMaster-Carr and they didn't have that info either... go figure

Anyway it looks like this:

I stuck a mag catch nut in frame for a sense of scale. If I were to guess I'd say in the neighborhood of 60/40 or maybe 70/30 favoring glass on the high end

Cheers

I have two 3rd gen 4046 and 5906. I just bought a blast cabinet from harbor freight and a blasting kit. I bought media randomly and will try on some stainless steel pieces of metal I have lying around. Questions 1. I will not dissassemble the gund but will tape off well and then bathe them in paint thinner or naphta etc to rinse out any debris after blasting any thoughts ? Any tips ? Great post by the way.

I think you rin the very genuine risk of WRECKING any gun that you blast without full assembly.

Imagine the interface between hammer and sear -- now imagine you pulling the trigger (or evem simply cocking the pistol) with that grit in there.

You certainly can't stop the grit from getting in there.

Old thread but very relevant.

The secret sauce is indeed #4 Econo blend from Mcmaster-Carr!

Blends perfectly.

70psi and 4 inches away in circular motions.

Then for blend pull back and sweep towards original finish.

I will say this.

I have bead blasted many items with mainly WAO open air, and it's a mess.

This glass bead mix is down right evil stuff to use.

Respirator and goggles are a minimum.

That glass finds its way into the skin.



Thank you all so much.

Just picked up the benchtop blast cabinet from HF today. Ordered the McMaster media online, hopefully it will be here in a few days. I will post pictures of my results. I have several Gen 3s that need finish touchup. Thank you guys for blazing the trail so I don't have to trial and error.

That media is expensive though. $33 for 10 lbs, plus $9 shipping, dang.

I went ahead and bought a 25lb bag of 80 grit glass media for general use from HF also.

Has anyone treated the barrel hood (the part exposed from the slide) with blast media? Use the same as on the slide?

Thanks,

Rosewood

Use the 80grit glass beads at 80psi on a stainless 1911 frame that had scratches. Cleaned it right up. Do think I would like something with a little more shine afterwards. It is gray now.

I agree, a little too grey.

Looking forward to seeing your results from the McMaster media as I have a c couple of newly acquired gen 3s I want to look new again as well.

I already have the table top blast cabinet from HF. Did you use the media spray gun that came with it?

I did. Worked fine. I also used my shop vac to keep the dust down. No issues there. I also put duct tape over the grommets where I had heard reviewer say theirs had leaks from. Worked perfect. Put 2 of those HF LED light switches in the ceiling of the cabinet with magnets, seemed to be plenty of light for me.

The media came in Monday night, but it has been raining and didn't want to be using it with the high humidity just in case. Hopefully I will be able to give it a go either tomorrow or Friday evening.

I still have to clean out the HF media from the cabinet also before using the new media. I will post pics as soon as I get the first one done.

Here is what the 1911 looks like assembled. The frame is darker than I would like and a rough texture. Again, I used the 80 grit GB from HF. I would have thought it would have been similar to the #9GB you guys tested with, but it looks way darker to me. Do you guys think if I hit it with the #13GB, it would lighten it up?

I hope to try out the McMaster #4 this evening on a S&W slide.

Thanks,

Rosewood

I've been watching the progress and I'm looking forward to seeing the McMaster-Carr media on the slide.

I've also been watching BMCM's thread on fixing up a rough blast job on a 1006:

M1006 in for some spa treatment

Post #7 seems extremely relevant to your situation, and gives great advice on how to even up your frame's finish.

If you are after a brighter/shinier finish than the standard S&W finish, #13 glass bead media with lower pressure would be the way to go.

The lower 4006 in this picture was blasted with #13 (it might have been #9 - it was a long time ago), while it looks darker in the picture it is brighter/shinier in person.

McMaster Carr #4 is indeed the secret sauce. @70psi

Left and right are before, center is after. The 3913 was somewhat shiny, not sure if it was wear or someone polished it.

Now if I could figure out how to touch up the anodizing myself...


Top end looks like a new gun.

Bmcm &skjos, do you guys think if I hit that 1911 frame with the McMaster, it will lighten it up? Or am I stuck with it because it was a courser media? Thanks, rosewood

It should lighten it up, but I would follow what BMCM did and knock down the high spots first with sand paper. Maybe start with 60psi and dial it up to 70psi if necessary. You may also be able to lighten without blasting using a fine scotch-brite pad.

I'm not sure when your disassembled slide picture was taken in the previous post, but the extractor should be removed before blasting.

I was able to remove the extractor on the 4053. However on the 3913, I broke my punch, it just wouldn't budge and that was clamped in a vise and a steel hammer and punch. Gave up, I taped it up well and flushed it out with carb cleaner and air hose after finished.

That particular pic was taken in the living room where I took everything else apart at. Had to take to shop to get something solid enough to drive that dang pin out...
