Hi Jer, great idea, as a welder I would advise using unplated nuts, the arc will strike better and you'll get better penetration into the nut, thank you for your videos, your content is always very interesting.

[@gottafly2day]

Yep. Muriatic acid (hydrochloric acid) is great for quickly dissolving the zinc plating. I do this all the time.

[@KenFullman]

Not to mention the highly toxic fumes produced from zinc in welding.

[@billmoran3219]

You can wire wheel them also to remove plating. I would also recommend spraying bolt with anti splatter and also remove plating.

[@davidelliott5843]

When done coat the inside with water displacing anti corrosion fluid. Otherwise it will rust - badly.

[@jafo766]

I weld a strip of metal 3/16 or 1/4 thick on inside the length of tube , a few holes in length of tube to weld strip and grind flush , that cuts down on the 80 holes to weld nuts on and now there is threading meat in there , another tip , avoid drilling and taping through that bluish work hardened seam in tubing , use opposite face.

[@alansexton6940]

Forget the rivet nuts, this is a diy solution, well done.

[@rom14141]

I wouldn't consider rivet nuts expensive, especially considering the time savings . I do appreciate your approach, it's valid and a useful option to have. Your video was entertaining, informative and easy to follow.

[@453421abcdefg12345]

Also compared to the cost of buying a Lathe, Mig Welder and de burring tool the rivnut would be a much cheaper option.

[@RickLowrance]

I admire people that can weld well. I cannot. Rivnut is the answer for someone like me.

[@travismiller5548]

Rivnuts lose their grip and spin out, particularly in aluminum. Used as a last resort in the commercial signage industry- always with an additional adhesive, such as Lord's.

[@453421abcdefg12345]

@@travismiller5548 So how do you weld aluminium nuts inside aluminium square section tube?

[@benargee]

Yes, if this is for professional work, it's a waste of time. If it's DIY, it can be handy if purchasing cost budget is the main priority. Always interesting to see new ways of doing things. Also a good method in a pinch of more conventional methods are available.

[@bobflores]

Thanks for demonstrating this solution outside of your project video. I'll look forward to seeing this in a project.

[@bmlennox]

if you want an even sturdier solution weld the nut onto a piece of flatbar, then plug weld the flat bar in similar fashion. The nut could be welded full circumference (much stronger) and you can use multiple plug welds on the flat bar distributing the torque along a great surface area.

[@jimanderson4444]

I agree, not many fab shops have a lathe , yet often I could use one , over all good work ! Jim

[@ghydeon]

at that rate you could make a box out of flat bar

[@realemonful]

In this case your suggestion makes as much sense as building one ship above another one... Just clueless SMH

[@Angorek55]

Makes more sense to drill and tap the flatbar, instead of welding a nut.

[@hansnoeldner1861]

Nice idea! FYI you can get Rout-a-Burr bits with a hook shape for deburring inside walls - and they work just fine. I also recommend using integral-flange nuts - they spread out the load more and also give you more material to weld to.

[@Si-Al-Ti]

Going straight to the playlist of clever stuff

[@tcarney57]

Apparently most commenters just want to buy a solution (rivnut, etc.) rather than create one. I'm not sure if that's because they have too-much money or too-little ambition (or creativity). The least-impressive ones pretend to be economists engaging in cost-benefit analysis ("time is money," "a rivnut tool is cheaper than a welder," etc.). Their merely-commercial attitude leaves me cold, but your approach to this resonates with every (well, most) fiber in my being. It's the way I was raised, the way I watched my father approach his own work (personal and professional), and the way my best friends pursue theirs. And it leads to growth and dignity in other aspects of life as well. Do it yourself, and then share what you've done with others. Thanks for both the doing and the sharing.

[@juliogonzo2718]

Very cool idea! If the thing you are making is going outside make sure to antiseize the bolts. Nothing sucks more than a captive nut coming loose inside a boxed in thing during disassembly

[@jimmylovesbikes]

Fantastic tip that I must remember when the situation calls for it. Thank you!!!!

[@justincomisk]

Clever. The threads sheared on my cheap riv-nut tool, so I bought a quality one and it wasn't cheap. Also manually swaging a large number of riv-nuts can be tiring, so definitely gonna keep this method in mind.

[@adambialecki2696]

Brilliant idea!!! Lathing the shoulder on the nut even better, well done

[@avoidtheherd7066]

GENIUS! A solid carbide spade bit is made to drill thin steel. I haven't tried it yet but it is said to leave a burr-free hole on the back side. It is the go-to drill bit for custom-built handsaws.

[@JamesDHendrickson]

Always a good day when you post. I had to do something similar a while back and I just cut the tube in half then welded it back together. As usual your craftsmanship surpasses my brute strength methods.

[@gilbertmckown6161]

Love seeing this guy's diy projects. What a great and talented young man!

[@musicbymark]

Harbor freight sells this pop rivet type tool that instead of rivets, it fastens threaded inserts into thin-walled metal like your tubing here. I bought one years ago and have never had a cause to use it yet, but it might work beautifully for this situation. However, your method was brilliant to be able to weld a nut inside a tube like this, inconspicuously cover your tracks, while not getting a speck of weld into the interior threads! You always impress me with your brilliance Jeremy :-)

[@Jer_Schmidt]

The rivnuts still have a slim head on the outside of the tube, right? I wanted this to be totally flat on the outside, and of course just wanted to show a solution that doesn’t involve buying a specialty tool that rarely gets used.

[@musicbymark]

@@Jer_Schmidt I'm almost positive they do, just by design like a pop rivet. Your method was clever and much more sturdy than this would be. That said, I've been waiting for years to come up with a use for that damn tool!

[@NaturalBBler]

@@Jer_Schmidt Yeah i was thinking the same, and now i use this rivet gun so often. It is a problem solver so many times

[@felixar90]

@@Jer_Schmidt you can get countersunk head rivnuts that are flush with the surface, and you can install them with a bolt, a nut and a washer. Of course it’s faster with the tool. And you don’t have to drill 3 holes for every fastener.

[@elesjuan]

Unless they've updated it in the last five years, don't buy the harbor freight one. It failed after the third rivnut.

[@Bonjour-World]

If one does not have access to expensive metal working equipment (i.e. welders, lathe, etc) try a bit of grease on the threads and JB WELD on the face of a flange nut. Use a bolt and jam nut to pull the inside nut tight against the inside surface (tight enough for the flange serrations to indent the metal) and leave for 24 hours. It is not as strong as welding but it is another alternative (that works with dissimilar metals ... example: Steel nut and Aluminum tube).

[@davidhughes7888]

You are a fantastic communicator Well done.

[@fredcheung1940]

I must say that your approach is clever, something I don't think I would have ever thought of. However, as others have already noted, it does add a lot of labor. A few years ago, when I purchased a new Ford F-150, I did a lot of projects involving adding/securing items to the truck bed, which is aluminum. I just went ahead and purchased a rivetnut setter, and it has been a wonderful purchase, for which I have no regret. There is no way I could have used your particular method, considering the thin aluminum sheet, sprayed-on bed liner, delicate wiring and hoses (on the underside). For some of my other projects, your approach may be a good solution. Thanks for sharing.

[@mabmachine]

What a innovative idea. Now I need to find a use for this.

[@charliema3762]

Nut plates, or flush mount t-nuts would make this operation easier. Having a flange means you won’t need to reach in through the hole, so can use tig (I don’t have mig) or just flush rivets. Regarding rivnuts: they don’t sit flush (at least the one I have do not). Jer, I have enjoyed your videos for years (bought multiple plans from you and built your grinder). Am so happy you are now posting more frequently!! Keep’em coming!

[@legallyfree2955]

This is not the technical term for them, but I have used those "countersunk Phillips drive" bolts with the head diameter sanded down using a drill and belt sander so the head is only slightly larger than the hole to hold bolts in place before for welding them on through 4 holes before although it was in a different application (welding on to flat plate that I didn't have full access to the other side and I remember spending probably half an hour or maybe more trying to get the nut in the right place on the other side with a piece of wire wrapped around it before I thought of using a magnet hot glued to a stick to hold it while I threaded the bolt through, after which I realized I could have just hot glued the nut directly to the stick but you know, you think of the good ideas later...)

[@fuckingpippaman]

there are flush riv nuts. You just countersink slighly the hole

[@blvckbytes7329]

​@@fuckingpippaman It would weaken the push strength of the rivet immensely if you'd countersink such a thin pice of metal. I know, they're mostly meant for pulling forces, but still. It could fall through while assembling if you knock it once. The idea in this video is pretty nice, as even those little tacks can take quite the beating.

[@DarylHiers]

Yea, there are plenty of ways to do this without going thru drill bits like candy that are cleaner and easier that cost the same or less than zinc nuts. This video has some bad advice IMO.

[@kennethelwell8574]

Weld nuts are another option. Essentially a short bar with an extruded thread, the tab(s) give ample space to weld. The extruded thread is easy to locate in a clearance hole, and works like your modified nut with threads closer to the surface, and a lower profile inside. Now, weld nuts and rivnuts/rivet nuts are often employed in situations where assembly happens ONCE, usually for flat-packed items to be assembled on-site, or limited cycles such as access for replacing a component once or twice. I'd prefer the more solid threads of real nuts for something seeing repeated use. Others have mentioned flange nuts, there's also "heavy" hex nuts, which are basically the next size larger nut with a smaller thread, and there's "heavy jam nuts" which are a combination of larger width, but normal thickness (regular jam nuts are thinner than normal nuts)... So, there's lots to choose from, for thread engagement, width, thickness/clearance, if the standard hex nuts aren't good enough.

[@darylcross5610]

Thanks I was aware of several but not all these options you have listed thanks👍. I have also heard riv nuts can loosen over time if exposed to vibration and other forces. Was told Not to use them for side panels on a trailer crate for this reason.

[@HWPcville]

I like your solution. I have the same equipment (mostly) as you, so using what I already have (vs finding specialized nuts & tooling) appeals to me very much. Thanks for posting.

[@barry7608]

Thanks I like it. When I have had to de burr some distance from the end I made a little jig that fits inside and can be pushed in with a rod to the required distance. The jig can be made using any hardened steel with a sharp leading edge that will cut the burrs quickly and cleanly. The jig can be made easily and can be made to be adjusted to tube size. Also whenever I weld nuts while a bolt is threaded I use a smear of anti seize or spatter guard to ensure no lock up.

[@Donorcyclist]

Well, that was beautiful! And great job welding those holes in so quickly! I’d be chasing it as I burned through the thin wall material…

[@kevinmcguire3715]

Use a drill press vise! A high school buddy that we interred recently at age 70 had his thumb yanked out by the roots 50 years ago because he was doing the same thing. That drill bit just has to catch in the material and its all over 'cept for the crying. Thin wall is basically sheet metal folded up and can become a rotating knife in a blink. Just a tip from a retired tool and fixture maker.

[@secondarycontainment4727]

You should look into FRICTION DRILLING (flow drilling / thermal drilling) and TAPPING. All you really need is drill and a tungsten carbide flow drill bit. You can take thin-walled stock and essentially thicken the wall for tapping... no inserts or bolts required.

[@joelhollingsworth2374]

Great method, as always. And thanks for putting out a quick update!

[@aserta]

Some tips 1. non serrated flange nut. Extra meat to weld to, less chance for the weld to deform the threads, because it's round, three holes can be made, giving even more power to that connection. Bonus, because of the flange, there's a little more thread too (in most cases, these nuts are slightly taller than normal nuts). 2. shoulder bolt instead of threaded bolt. The shoulder can be matched to a drill thus giving you even more accuracy. 3. Noga RC2000, nuff said. Worth having that tool.

[@legallyfree2955]

I had no idea something like a Noga RC2000 existed. Something else to add to the shopping list.

[@Joe_Bandit]

Cool idea! You could also just drill an oversize hole and weld the whole nut or a slice of drilled and tapped round bar in flush with the surface, using a magnet to stop it falling into the hole.

[@legallyfree2955]

You can unless your trying to do it to M8 nuts and your drill bits top out at 10mm ;) , I need some bigger drill bits. Although I think I have imperial that goes up to 1/2" which would be 12.7mm, which would be large enough for M8 nuts.

[@nefariousyawn]

Okay I was going to say "rivnuts," but you addressed that right away. Your solution for the given problem is excellent.

[@nefariousyawn]

[@DEADB33F]

Some great tips. Rivnuts really aren't that expensive though. I use them all the time and 100 M8 Rivnuts cost like a tenner. I think my putter-inner tool was another 20-30 quid, which I guess is a bit of an outlay but not that huge IMO. I'd say that the biggest downside to all the rivnuts I've used is that they don't finish up flush with the outer surface. Although I've seen that you can also get ones designed for a countersunk hole so they do end up flush (still working through my stocks of regular ones but will be getting these next time).

[@scottcates]

Agreed

[@fuckingpippaman]

countersunk rivnuts from Ali for like 10 cents each a bargain

[@bikerfirefarter7280]

You don't need a setter tool to fix rivnuts, a decent bolt and a socket or spanner will do the job, but it can take a while to get the technique right. I use a power screwdriver to set the smaller ones. But if you are doing lots of them a proper setter is convenient/quicker.

[@DEADB33F]

@@bikerfirefarter7280 Before I bought the proper tool this is what I'd do. It works ok, but if the rivnut doesn't sit tight in the hole you risk it becoming loose and spinning part way through crimping the barrel. Adding a stack of greased washers can reduce the torque transferring to the rivnut and that helped a bit, but this was still an issue I ran into sometimes.

[@Malkohm1]

I’ve used this method but it was very time consuming ie . Labor intensive. I’ve achieved similar results by over drilling holes, sliding wood backing and then top welding nuts. It provides max clearance on inner tube and was much faster. Great video , thanks for posting. I’m always curious about new ways of getting the work done. Cheers

Jer, you can get a blade for your deburring tool that is designed to deburr inside edges of holes. You can even get ones that are made to deburr both edges at the same time and just push or pull on it to only get one of the edges.

[@chrisharvie-smith486]

Also three holes & welds would prevent moving the bolt breaking the looser attached ones (Fatigue fractures with back & forth bolt movements).

Thank you for sharing some good tips! I do feel there are some better alternatives, at least if you need to do more than a couple of these. For example there is the blind rivet nut which is a very cheap option. Changing the construction is often a better way to deal with when possible. Maybe a aluminium profile (can't find the right english translation for these) for machinebuilding could be used. There are steel alternatives too. Thank you again for sharing :)

It's another tedious step but thinking of this would also make me consider welding a fender washer to the nut first, and then you could just weld the fender washer/nut combo through the plug hole. I think there would be less chance of error in accidentally touching the mig wire and prematurely plugging the hole before a good weld is made. (Note: this is just my hypothesis.)

i'm going to make your day, im one of those old guys that had to improvise my entire life because back in the40s and 50s we made our own specialty tools. today imagination has no bounds as far as tools. ive even invented a couple that worked but didn't take off. for what you are doing, that is needing to reach inside and hold the nut is something we have always had to deal with.a company called handee clamp makes something so simple and useful your head will just think, why the hell hasn't anyone done that before. can be bought most anyone, about 20 bucks or less. made to reach up through bumpers or cavities to hold a nut in place till you do what you want. it is perfect for that job. i got mine from amazon , free shipping etc, lisle tools im sure had one. looks like a flat piece of metal about a foot long, one piece flat fits inside one piece with sides bent over to make a simple slide. one end has the end turned up 90% ON bottom piece. top piece has the same bent over tab at same place, the tabs are turned up about a quarter inch so you can lay a nut in the opening and hold it in place. at other end is a threaded bar and round nut to snug the nut up and hold it in place till you bolt it or weld it . its name is handeeclamp.com a c&c product this little tool will do what you want and if it doesn't you can bet it will be useful later.

[@blindsquirrel4882]

Brilliant!

[@ScamstinCrew]

I did the idea and usefulness. Drilling access holes to fill and tack nuts in place is slick. I would add something in there about covering the nut with anti-spatter so you don't get a seized bolt after welding the nut in. Rivnuts are not that expensive and you can use a bolt and can install them Without the tool. Though the tool is also not too expensive. I do feel nuts welded in like this would have more holding power than a traditional Rivnut.

[@darylcross5610]

Riv nuts can work loose and then you cannot undo the bolt because the ffnn thing is spinning and laughing at you.

[@tomhofmann5277]

Brilliant, as I’ve come to expect from you! Thanks

[@DIYToPen]

Here's an idea for free... cut a small cross in the tube, line the nut up on the cross, hammer or press it flush, then weld around it. Grind the weld flush. Might need a tool to hold the nut in position, some sort of tube, but it would need an overlap or a stopping mechanism so that you don't press the nut too far. edit: In fact, even that is too complex. Drill a hole larger than the nut, weld a tripod on to a bolt with the bolt longer than the tripod, thread on the nut, place the tripod on the box section, hold with one hand, weld with the other, detach the tripod and finish weld, or finish weld then detach tripod. So many options, I'm feeling creative. .

[@messylaura]

4:00 shows the threads of the long bolt getting alot of splatter on them, most will fall off but some might mess up the threads on the way out, for this type of install i usually weld the nut to a larger washer or sheet of cut metal if its near an edge first, then when you weld in the nut and washer the washer / metal plate covers those two weld holes allowing you to weld horizontal and also stops the spatter from getting the thread of the placement bolt/s as a few have said the rivnut option is a good one, there are a few advantages and some cons, the main con for me on the rivnut is for an application where you would be constantly fixing and refixing items to the unit, there is a chance they can work loose over time and spin but for a one time install they would be fine i usually go the welded method with the nut on a larger pre welded washer / plate great vid

The zinc plating will leave you with a weak weld and in such a small area with limited burn time you have no chance of burning of a substantial portion of the zinc. Better to use un-plated nuts or pickle them before use to remove as much zinc as possible.

[@Jer_Schmidt]

Yes, uncoated would be better, but this is good enough. I tried putting a bolt in these and hammering on it, and the wall of the tube bends long before the welds break. Plus, under normal use, the bolt is pulling on the nut, not really stressing the welds.

[@gadavr]

May be faster make more massive tack welding on side, like flange nut, before placing it insude tube. And it will be easer weld them together.

[@r0bst4rl1ng]

And if you _did_ succeed in burning the zinc, then you're breathing it, which isn't good either.
