Sanding and Polishing Stainless Steel Keg to a Mirror Finish [4K] Part 1 HERMS Build

- Part 2 is now up • Building a Herms Keggl...
In this video is the first in a series I plan to do on how to build a HERMS Homebrewing system. HERMS means heat exchange recirculating mash system. The polished stainless steel kegs look great and were a cheaper option than 100 dollar stainless steel pots. They require a lot of time and effort to shine them up this well but the results are definitely worth it. I got the airway buff wheels from Renegade Products at www.renegadeproductsusa.com

Wow! Thank you,
D.O.I. ...when I wanted to paint my own car the paint store guy taught me the term. It stands for, "distinctness of image," (as a goal of the cut and rub). Silly to apply that here, since you're actually getting a mirror image, but that's what bubbled up in my mind.
Sick vid dude, much appreciated.
Awesome video, ive been trying like hell to find a good video on this. I sell on ebay for a living and I want to start polishing my Pans and Silverware before i sell them so that I can fetch top dollar. This was a HUGE help, thank you!
Glad to hear it! Good luck with the polishing!
Great video. Thanks for sharing your knowledge. 🙏🏽
Loved this...just got my first keg I want to turn into a table...this was perfect for a newbie like me...
Me too, how did it go?
@davepowell7168 it went OK Dave....not as shiny as the video because my tools are a bit more limited.. I used a drill and attachements...trying to remember because it was a while ago but I think after getting the inital rubbish off it, I think I used the orbital sander starting at about 320 grit and stepped up to about 800 and hand finished with 0000 steel wool....from there I used a buffer wheel (on the drill) with a cutting compound then went to the polishing compound. Not a perfect science and not as shiny as those in the video, but it suits my purpose as a small side table for drinks in our entertainment area.
Best of luck with your project, stay patient and work through the steps best you can
Great video and great information
Thanks!
Those look dope.
Rotary will remove material fast and can't stay on one spot. On the DA find a soft backing pad. It's more forgiving on the edges when sanding over ribs and things. Nice work
Is interestingue job ,very good works
fantastic
Very good
Is bealtiful work ,
Good your job
Thanks that helps alot
Its about time someone use an airway wheel for this application! I stumbled onto Evan's channel as well thought, "huh, I bet that would work great for a keg!". It sure as hell does. I've been working on polishing a keg with the "gator grit" method you see elsewhere and it is not this effective. I'll have to drop the cash on some Renegade products soon. Great work! We'll be building our HERMS system at the same time.
I honestly didn’t really believe the airway would work at first to take it from a 600/800 grit to shine but it totally does results are amazing. Best of luck to you!
@@TrevsGarage I had my doubts as well. I didn't even think to reach out to Evan about this specific application, so good thinking there. I know in the video you went up to 800 grit, but had you tried going from 600 to the airways? I may or may not be attempting to cut corners ;)
Also, I noticed the keg rolling on you a bit while you work. I found that a ratchet strap holding a pair of 2x4s to the keg keeps it rock steady while laid across a couple saw horses.
I did try going from 600 to airway. The result I think wasn't a fair test because I strictly rotary sanded. When I did 600 to airway I felt like I noticed a lot more "scratches" when the light hit in different ways, they were sort of just leftover swirls from the 600 rotary. If I had done an alternation between rotary and da sanding i think ending on a 600 da you may be able to make it work. The only other thing is that the 600 to 800 sanding step was probably the fastest step because I was doing a lot less deep cutting vs the like 220 step. So bottom line I'd say yes you can get away with it depending on how you do it and how picky you want to be with results.
Nice video.
Thank you!
Thank You Thank you Thank you!!!!!!
Thanks.,.
Good Job, Loves Evans Detailing but I like the way you explained each step. I have a Kenworth I’m redoing and will use these steps on the Air Cleaners. Thanks again.
Thank you best of luck on your Air Cleaners! With those you can probably switch between the DA sander and rotary for an even better finish.
Damn man, that's amazing. We put a Keg on our buggy and might have to give that a go.
Best of luck! Would love to hear how it goes if you end up doing it!
@@TrevsGarage did you polish the sides as well?
Like the top and bottom?
@Trev's Garage yeah, I saw you didn't after. Just curious: Man, the Renegade products look amazing.
Yeah i cut the top off completely and no need for me to polish the bottom. Products definitely worked well only thing if I did it again id like to try and cut down on would be the time spent sanding I’ve seen a comment or two with other prep suggestions to sanding and seen some other methods online too may try in the future.
Clamp a drill with a polishing wheel in it to your pallet or whatever and let the keg rest against it with all the other parts supported by casters so you can spin it as you work on it. More consistent finish and faster. Sometimes with something small, I actually chuck it into a drill, or attach it to something that i can chuck into a drill, (like I did a stainless steel thermos, I chucked a screwdriver, pushed the handle into a paint roller, then pushed the paint roller down into my thermos. I ran the drill pretty slow, and just held sandpaper, 320, 400, 600, 800, 1000, and finally 1500 grit - lightly against it, using mineral spirits-paint thinner-charcoal lighter as a lubricant.).
Use the stripper and then a EXL deburing wheel- 2SF..then buff. Save you a shit load of time!
I will have to give that a try thanks!
Good tip, thanks. 3M has these.
Good call on the 3M EXL 2SF!! I have 3M scotch brite roloc's in various grits, but didn't know about EXL.
The 1" wide EXL 6"- 8" wheels are pricy, so I almost didn't bite. But then I found 3" diameter, 1/4" wide EXL 2SF disks sold in a case of 40 for under $25, so I went for it.
I gave them a try using an air powered die grinder. They were the ticket! After using the stripping (blue) wheel with an angle grinder, I used the EXL's as the next step instead of sanding. It did everything multiple sanding stages would do in one pass. The disk wore down about a 1/4" after doing one keg. Thanks for the suggestion.
Word of advice for others - you need a stout compressor to do this with a die grinder. If your die grinder outruns your compressor when running it continiously, it'll be a long day. I don't know how well they work in a slower RPM tool (drill). Might be better off going step by step with a sander.
I've got a question. Is it possible to sandblast/beadblast/co2blast the keg during the first step for quicker removal of course material? Or is it too agressive?
I am from brazil🇧🇷
Great video! I’m looking to do the same thing, Will you be doing a video on building your kettles? What brew system will you be doing? electric, gas, HERMS, RIMS? 🍻
I guess I should’ve waited tell the end of the video before asking my questions 😂 can’t wait for more videos on this! 👍
Going to be herms the part 2 of the build series should be uploaded in the next day or two hopefully thanks for the support!
Is there a small version of the buffing wheels I need to do small parts what do you recommend? Video was helpful thank you
I believe you can get wheels that are like 4.5 inches just not from the company I used
Thanks to your video, I have started my own keg polishing. I have the strip disc in a 4.5 and 3 in. I am struggling to know when I am done with that step. I went over the whole thing twice really well (once with grinding paste) and then started with 220 metal sand paper. I tried a dual action and a rotary, but there are still scratches just from previous rough handling showing. I am unsure of the thickness and afraid I am going to sand right through if I try to get them all out. You mentioned stainless, but mine seems to behave like aluminum, so not sure what its made of. Any Advice? I, too, watch alot of Evans videos 🙂
I would suggest focus on a small area where there is a scratch like 4”x4” and polish it out to finish completely for a test. I had some scratches as well but once polished they are much harder to see and blend in somewhat since you would be able to sand all the way down as you mentioned. Not really sure how to tell aluminum vs stainless I just know a majority of kegs are stainless. Hope that helps!
Best way to do this is by yourself??
Would you be able to use this method on a surface like diamond plate? Such as the blue pad and sanding. The diamond plate isn't as rough of a finish as this so I don't think it would need such and aggressive approach
Apologies for the delayed response. Heres a good video showing similar technique to polish dimaond plate. Hope this helps.

Ive got a Dewalt DCG 418. COuld i achieve the same results with that single tool just with the relevant style discs?
Looked up that Dewalt model looks like it is an angle grinder. I think you may have trouble when using the sandpaper at those higher RPM's. I'd recommend trying a small test spot first. Best of luck!
What rpm did you run on the buffer? It looks amazing!!!
The angle grinder I used was from harbor freight. Its a large chicago electric 9" and is supposed to run at around 6,000 rpm. Apologies for the delayed response, hope that helps!
Hey nice keg! I am in the same process but can't keg a mirror finish. Would like to buy so buffing wheel. Did you use a regular grinder? (it turns very fast)
I used a 6000 rpm angle grinder.
Did you use a rubber backing pad for the strip discs on the angle grinder? Don’t have much experience with strip discs of that sort. What brand were they out of curiosity
No rubber backing pad they actually are a complete disc like a flap disc if you have experience with those. They just go on the arbor with standard nut. Heres a link to what I used. amzn.to/3vMM294
Great video. One question tho, what were you using with the airway wheel? Is that also an angle grinder or polisher? I've got a big angle grinder but it spins at 6k rpm...
6k rpm is perfect thats about what I was using with the one i used in the video. You can use less it just may take longer to buff out the sanding. I used a polisher to do the sanding much slower but angle grinder for the airway buff wheels.
How do you know when ti apply more material and how much do you apply to the wheel?
You can almost see on the surface when you are out of material you will no longer see it as you buff back and forth. When applying to the wheel you can see it on the wheel as well as you will start to see a lot of excess material shoot off when you apply the brick to the wheel.
You in Canada
Does this process work on stainless exhaust pipes?
Yes the same process will work!
Trev, I really want to polish a miror finish on an aluminum rim that has a lot of crevices. Can that be done? Thanks.
It can be done it will just take more time and attention to detail given all the crevices likely around the spokes I imagine. You may also want some smaller airway buff wheels to get into those tight spots.
@TrevsGarage Trev, thank you. I'll look into an assortment of polishing and sanding tools for this purpose. Again, thank you.
How many strip disc per keg did you go through? Same question for the sandpaper. 10 pack of each grit or more per keg?
Strip disc one pack of 5 will get you through all 3 easily. I want to say I used probably 2 total for all 3 kegs. Sandpaper I honestly was using probably 20-30 of the 220 grit per keg. That 220 was doing the majority of the cutting so I used less with the other grits. You can try to do less but once the sandpaper looses its coarseness its pretty much going to be useless.
@@TrevsGarage Thank you..
Hey, just curious about the 800 dura gold grit. Did you have problems with it flying off the grinder? Or is it just me??? Does yours have adhesive on the back? I used the links you provided for what you used, but since I've never done this before and i don't know anyone who does this around me I have many questions.
I did not have any issues with the sandpaper coming off at all. It had velcro type material for hook and loop style attachment.
You have to have a 5” “hook & loop” interface pad to put on whatever you’re wanting to rotary grind with. If you don’t have that, these velcro/hook and loop pads ain’t going to stick to just anything lol.
Which milwaukee m18 where you sanding with and the pad that hold the sanding disc?
Milwaukee M18 Variable Speed Polisher
amzn.to/3X4ilwh
Stadea 5" Rubber Backer Pad/Rubber Backing Pad with Hook and Loop Backing Arbor 5/8"
amzn.to/40ADXUc
Do you apply anything afterwards to prevent tarnish or rust?
I did not and haven’t had any problems yet
Is that Milwaukee a variable speed polisher?
Yes it is the 7 inch rotary polisher worked very well for sanding. Tried the backing plate on angle grinders but they just spin way too fast and discolored the stainless while sanding from the heat.
I'm a lil embarrassed to ask but how can you tell the difference between aluminum kegs and stainless? I bought a couple and the place I get them from have a lot more. The 2 I have 1 is obviously stainless judging by the welds. But the other seems like aluminum judging by the welds. The unpolished keg in the video looks like aluminum. Is there anything I should look for? Thanks!
There are a few tests u can try but they may slightly damage the kegs. Most kegs today are stainless steel. You should notice a weight difference between them when empty. Also aluminum will scratch far easier than stainless will. It will also dent much easier than stainless if you really want to find out you could try that in a spot that wont be seen.
@@TrevsGarage great advice! Turns out the one I have I thought was aluminum is stainless. Awesome! Thank you
What size airway buffs did you use?
9 inch
Why did you spray the wd40 on the keg while sanding? Is it necessary?
Awe shit. Never mind
Ill take 30 of these. I need them in 4 days… 🤫
If you didn’t need them so quickly I could make it happen
@@TrevsGarage I was kidding. Lol. Maybe you can spin these Lathe style as you are polishing?
Defenitley think that would help and speed up the process, just need some way to spin them
Are you certain those kegs are stainless steal and not aluminum?
They are stainless
Local pub keeps throwing them Out, i have two But I'm scared to play with them 🤨 Someone Please tell me I'll be Safe 🤗😇😅
Good video but no way I'm doing all this work before making the cuts and installing the triclamp connections.
Yeah agreed in hindsight I would have made my cuts first then polished second but still happy with the results!
which products do you use?
Everything I used is in the description, hope that helps!
@@TrevsGarage thank you
What is this "Meeer finish" you mercans always say? 😂
Mirror finish
Stainless?
Yes
@@joeyrichardson3040 Awesome. I was thinking aluminum
Every keg I've seen is aluminum
If you cut out every other word your video would be 8:24 mins. Then we wouldn't have to skip to end. Jk I watched the whole video
I agree! I kept jumping a few minutes and w ent from start to finish without seeing any actual work 😂
Too much waffling get to the point!
Doesnt want the video long then talks for ten goddam minutes
Get to the fuckin point chatty Kathie!!!!!! Sheesh
