- The last video I put up about soldering a spud into a brew vessel, my battery ran out so it wasn't complete. This one shows from prep to cleanup. The welding spud fittings are available on brewhardware.com and you can pick up a silver soldering kit including the solder and flux at Home Depot.

The man knows the significance of drilling slowly.
I have been soldering plumbing and electronic for years. Never tried stainless steel so thanks for tips I'm looking to see how well it works !
Hey Bobby, Thanks for sharing this with us knowledge is power..
Good video thanks for yet another upgrade idea to my kettles.
Awesome video. You are very precise with your methods. Thanks for the great info.
I think it's semantics. You either have brazing above 840F or soldering below. While some refer to brazing with high silver content solder as silver soldering, I consider soldering with low silver content 8% alloys as silver soldering. If you're brazing with something like 50% silver, I'd rather call it silver brazing. I don't know, that's just my preference. I'm clear in the video about using 8% silver so for those who want to call it plain soldering, cool. Cheers!
Great tutorial Bobby...Cheers!
Excellent video, thanks!
cool I feel confident now to try that myself
I use plain old vegetable oil in a solo cup to lubricate my step bits for cutting. Comes off easy with soap and water and you don't need to worry about petroleum products in your brew vessels.
soloban81 animal grease works well. So is having a wide point on your bit, 135° cuts metal way better than a general 118°.
After seeing this performed I am confident that I can do this with a few of my pots and eliminate a few weldless bulkheads on my system. brewharware here I come!
Yah. Stainless steel "work hardens" faster than any metal I know of. Nice job!
been waiting for another vid
Don't want to a jerk but you need to use cutting oil
or any heavy oil to keep temp down to save the bit and
make a clean cut. Heat and speed are the enemy.
Love your stuff.
Personally I would have tinned both surfaces first to ensure full coverage, then soldered together…
Mostly that easy. Keep it clean, use the right flux and boom.
A big part of it is using the right solder. I've tried this several times using "95/5" silver solder. Turns out that was 95% tin, 5% antimony ! What you need is a solder with actual silver in it. Staybrite is 96/4% silver and Staybrite 8 is 94/6% silver.
You're not being a jerk. A lot of people have trouble drilling stainless and by FAR the biggest problem is using too much speed. The reason this happens is that they don't have a drill with enough torque to keep the speed low. In pots like this, or thinner, you don't really spend enough time drilling to absolutely require cutting oil (if you stick to low speed, high torque). This Chinese import bit in the video has made at least 20 holes like this. If I go out to 1" or larger, I do use oil dips.
The only thing I would add to this video is, even if you have a stainless wire wheel, you better be sure it wasn't used on carbon steel at any time.
Thanks...
I've watched people burn up bits in 5 seconds by spinning the bit too fast and not pushing hard enough to get cutting immediately. If the bit is not pulling a ribbon of metal on every rotation, it's full of fail.
Bobby, why you waste your time replying to some of these know-it-all d bags is beyond me. Anyway, great instructional videos. I appreciate them all.
One question...should I be concerned about this connection breaking as I tighten the component threading to the bulkhead?
Thanks again.
Successful work !!!
great video!
The secret to silver solder is "Don't be shy with the flux" I use 'silphos" and tig welding to build my stills.....
Dam good job
Nice
Very goooood
Hmm, so it is. Thanks. They should call it stay brite 6.
nice ,,
My only critisizism is this: I would have scuffed up the mating surface of the bung fitting, too. Maybe you did it off camera but, both surfaces need to be scuffed up to make the most reliable joint...
Great job. Ever tried to solder a locknut to the keg? I'm gonna try it but wondering if theres any videos out there?
What size and where did you buy that pot? I need one exactly like it. Brand and size. looks like an amazing quality pot.
That was a junkyard find that was mounted to a huge industrial kitchen sculpture. There were no markings.
It's a nice job, but why did you not show the soldering step???
Can you link to the flux and solder?
As you are using 8% silver solder, can we consider it food grade? I wonder what can be considered a food grade solder, high silver and Lead free?
Nice tutorial, but without the right flux, forget about it !
Any new vids coming soon?
Really nice video thanks for sharing:)
I would like to try this, but a welder told me, that stainless ain't stainless anymore when it has been heated. Have you had any problems with rust after the soldering job?
Thanks
Jens
Sorry, your welder is greatly mistaken and frankly I would not trust him to do any work for you. If it were true, you wouldn't be able to weld stainless either. You will simply have to clean off any heat discoloration with a stainless wirebrush, sandpaper, a polishing wheel or similar. The remaining clean stainless will pretty quickly re-form the chromium oxide layer than makes stainless stainless. It can be helped along by an oxolic acid treatment which is commonly found in the form of powered stainless steel cleaner in the supermarket.
I'm in the process of making a custom made stainless steel sanitary pipe fittings nozzle prototype, wonder if I can use this just to build my prototype with this welding technique before sending out to the professional shop please advice. Thanks in advance
can it hold if i use to solder on my motorcycle exhaust pipe?
Great video Bob. I know ya posted this 6years ago...just looking for info.
Why not just hole drill it..? Any reason..? Thanks for posting
That punch method is pretty slick though.... I might try to find one..
Nothing wrong with drilling it. I much prefer using tungsten carbide hole cutting bits these days to all other methods.
I'm having Kettle Envy.
I want to this type metrial.
Hey Bobby, would this technique be good for soldering a bulkhead? If so that would be great cause all I would need is the solder.
hi sir thanks for video , please where to get them filler and flux , and what reference , is it silver braze rods , ?
thanks
HEY. WATCHED THE VIDEO DECIDED TO APPEAL TO YOU. WOULD YOU GIVE A FULL TITLE AND IT IS POSSIBLE TO BUY THIS PRODUCT. I NEED TO TRIM THE COPPER TO THE STAINLESS STEEL. PLEASE.
If you are asking where to buy the products he is demonstrating, go to www.brewhardware.com. He has everything you see in the video and a ton more. The process discussed will also work with copper to stainless.
great video. do you know where i can get the ssf-6 silver solder. keep up the good work.thanks

The Stay-Brite 8 is available on EBay, Amazon, supplyhouse, and at some local welding supply stores.
Is it that easy? Just heat it till the spud drops?
Hi Bobby, I have a kettle and fermenters already fitted with your silver solder fittings, I’ve found them to be extremely reliable and they also look great.
Have you had any experience with anyone fitting a bottom drain like this to a sandwiched base, ie a layer of aluminium between two layers of stainless?
Nope. I get the question a lot but no one has been brazen enough to risk their pot to find out.
That was not silver solder?
Sure it is. "The only difference between soldering and brazing is the temperature at which each process takes place. Soldering takes place at a temperature below 840°F (450°C), and brazing occurs at a temperature above 840°F (450°C)." This process was at about 450F so silver "soldering".
Great video. I wanted to ask you what is the composition of that liquid? Phosphoric acid? I ask this because here in Italy I can't find this product, I would like to consider a similar one with the same chemical composition (without ordering on the internet) Thanks!
I have no idea what is in it.
@@BobbyFromNJ Thank you very much
It's zinc chloride, used to be called 'killed spirits' in the UK. You make it by adding zinc to hydrochloric acid until it doesn't fizz any more. Note, I believe the yanks' name for hydrochloric acid is muriatic acid.
Mapp gas (can't get it any longer) or mapp pro? (which is not hotter than propane). Propane is not hot enough to silver solder or braze. So, I'm guessing you have an old bottle of mapp gas, so, this process won't work for anybody else unless they use acetylene.
Right, this is soldering with 6% silver content, not 50% solder so it only has to be 430F.
where do you get your fittings and pots from?
+mark vylonis
u get fittings on ebay (china)
Hi, is this container aluminum or stainless steel ?
Stainless. You can't solder to aluminum.
Stay Brite #8 by Harris is not 8% Silver, it's 6%.
He was using Stay Brite, which is 4% Ag. www.harrisproductsgroup.com/en/Products/Alloys/Soldering/Lead-Free-Solders/stay-brite.aspx
Stay Brite 8 is % Ag. www.harrisproductsgroup.com/en/Products/Alloys/Soldering/Lead-Free-Solders/stay-brite-8.aspx
Don't confuse these with 95/5, with is 95% tin, 5% antimony.
just stating; how could you name this video "FULL SOLDERING PROCESS" without ever showing the process of soldering
I literally showed the process of soldering in the video. What exactly did you think you were going to see, but didn't?
Hmmmm I know that tippy
WHY DID YOU CUT OUT THE ACTUAL SOLDERING?!?!?!
I didn't. At about 7:45 you can see me applying solder to the underside of the fitting. AT about minute 10, you see the heat melt that solder and the fitting drops down. I didn't skip the soldering process.
Is this food grade safe? Thanks!
VV V of course
Thanks a lot! :)
What's to keep the solder from melting again if you have the kettle on a flame for 60+ minutes?
Liquid in the pot. Yes, if you put the pot on a flame completely empty it is possible to heat it up over 400F and then the solder will melt again. If you have liquid in the pot, it won't get much hotter than 212F.
The gas you heat your kettle up with burns a lot colder than the gas you use to braze.
WD40 isn't lubricant, it's a penetrating fluid :p
But aside from that, awesome :)
Though it's not job specific and more of an across the board product, it does have some lubricating qualities. Even WD-40 thinks their product has lubricating properties (though they are probably a little biased).
From: wd40.com/cool-stuff/myths-legends-fun-facts
"A QUESTION OF LUBRICATION
Myth: WD-40 Multi-Use Product is not really a lubricant.
Fact: While the “W-D” in WD-40 stands for Water Displacement, WD-40 Multi-Use Product is a unique, special blend of lubricants. The product’s formulation also contains anti-corrosion agents and ingredients for penetration, water displacement and soil removal."
Who hasn't used it at least once on a squeaky door?
Jeremy Colby
I'll concede that it can be used as such :p
But, wd40 dries out, often quite fast, so for anything more than short lived use it's not great for lubrication and many people will use it as a full on lube eventually falling foul of this!
+MiggyManMike "WD40 isn't lubricant, it's a penetrating fluid" Its both, primarily a penetrating oil, however its a light lubricant.
+MiggyManMike Evaporation is a pretty efficient way of cooling though. I'd object to iy for other reasons tohugh.
it's neither. WD stands for water displacement.
Why not showing the soldering...? pfff
What exactly do you expect to see that I didnt show? I am soldering starting at the 10 minute mark.
Half the video was spent drilling one hole.
Ric Oestreich most of the people watching this video don't even own a screwdriver and there's a reason for that so the more description the better I think I was just waiting for him to work hard in that stainless with that step drill as fast as he was spinning it
@@robertatwood2503 if its cutting on each turn, it will never work harden.
um not silver solder, this is plain soldering, silver solder (AKA brazing) would have the joint glowing,
Not with high silver 55%…lower melting point..
That's not silver solder that lead or no lead solder. I worked on A/C units for 43 years and used silver solder and it more heat and a lot stronger.
Silver soldering is a misnomer in the industry and it has a lot of history behind it. The American Welding Society says that anything done over 840F is brazing and under is soldering. Of course there are grey areas due to the different alloys available. The product I'm using in the video is Harris Stay Brite #8 which has 6% silver and melts at 430 degrees. If it's not soldering, you tell me what it is. It melts under 840F. Just because someone commandeered "silver soldering" to mean brazing with silver alloy isn't my fault. Call it what you want.
I'd say "silver soldering" begins with 50% silver content solder which is the minimum silver content most higher end suppliers sell in their "silver solder" category.
I think using documented definitions of soldering vs. brazing, such as that of the AWA is probably a better way to define it than a welding supplier's product categorization. It's one of those things that snuck in the back door with old time tinkerers. Even the alloys with 50-70% silver content are named things like Braze 505 and their use is clearly defined in product guides as brazing. If you wish, I'll try really hard to talk about it in terms of soldering with silver bearing solder. It really doesn't matter all that much since I'm naming the exact product in use.
James Acker lol a/c units get brazed

Those japan made stainless steel stock pots don't last there not worth putting work and money into. I had one, and used it for a boiler and after about 10 runs it cracked and started leaking.
then you overheated the shit out of it and cooled it too quickly. treat it like you would a cast item
Personally i would rather just TIG weld or (or even MIG weld it for that matter) over soldering
Of course TIG is preferable but it's a machine and skillset that 99% of brewers don't have. Actually it is also a skill most supposed welding professionals don't have either. MIG? No. I would rather solder. If you can do a great job welding, more power to you. This video wasn't meant for you. Cheers.
why do Americans always call it sudder.... it has an "L" in it that everyone else uses...
I don't know. I didn't start it.
Annoying intro.
John James then don't watch.
buy a tig welder
Right, everyone that wants to put a fitting on a pot once or twice should drop a grand, practice on scrap for 3 months and THEN weld the fitting onto the pot. Very logical.
