I like how you not just highlight the things this stuff CAN do, but also mention the use cases that it CANNOT do. And I also like that you used a torque wrench to get reliable, objective data. Thumbs up!

For someone wanting to fix a broken bolt hole in aluminum that simply cannot be drilled to the next size, they have a workable solution.

@dennisrobinson8008 2 года назад

@@manniefresh7354 It works. I had a broken bolt hole on a aluminum block. It "only" needs to hold 45 ft-lb. I was able to correct by using this technique with harbor freight "alumiweld" rods. I was able to test it up to 55 ft-lb without issue. This was on a M10x1.5 hole.

Now when you take into consideration what and where you are using this...this was a very useful demonstration. If the threaded failure torque was say 20% higher than the normal use torque, then you are PROBABLY good for everything but critical failure parts.

@pk-teia6249 4 года назад

Hello Del and thank you so much for a great channel! Thought I'd share a little tip I lerned while working in the ship building industry. While drilling and making threads in aluminium or other soft metals we know that sometimes the swarf will smear and not break clean off. We end up with a shitty looking hole...excuse the pun ;) Try using denatured alcohol as a lubricant instead of oil. That will help the swarf break off cleaner and you are less likely to get smearing of the hole or threads.

@Moonfleet41 4 года назад

Thank you Per, a buddy of mine has suggested the same lubricant too.. i was using plain old WD40 for cutting with this one, a good 'second row' option i understand.. as i paraffin apparently.?

@ronanrogers4127 4 года назад

Interesting. Good demonstration. Whether it might fail in use due to greater hardness is purely hypothetical unless it’s tested. I think the point of failure in use might just as likely be where the new material joins the original material, rather than the original material itself failing through vibration...but we don’t know!

@matthewsellers82 2 года назад

I suspect from Delboy's perspective cautioning against the use on critical components is a hedge against any liability in the event of failure

@Moonfleet41 4 года назад

Hey Jim, exactly that mate, I don't think it wold ever replace a proper thread insert, the only time I think it would better it the insert option would be where there's nowhere to drill out in to extra metal (but there usually is)!

Great video Dell, I thought it was going to let go every time when you got above 50lb, really interesting content. I attended night college a couple of years for a pretty comprehensive welding and brazing course, never got to play with these though, they remind me a bit of brazing, heating the parent metal and adding the filler rod, not quite the same but similar. Thanks Del, love your content!

@kirbytabor9956 2 года назад

Hobart and Blue Deamon seem to be holding up👍 You really should use a better quality rod 👍👍👍

@michaelbrinks8089 2 года назад

The 3 biggest mistakes people make when using those rods are #1 Not properly scuffing the surface to remove oxidation with a clean stainless steel brush #2 Not welding right away after scuffing (the aluminum starts to oxidize in seconds after it's scuffed up #3 Using the flame to melt rod, instead of heating the part/getting the part hot enough so that it melts the rod when the rod touches the hot part. You use the same heating technique as you would when you join copper pipe with solder. You get the copper hot enough that it melts the solder when the solder is touched to it. If you try & melt the solder with the torch, it won't stick. I tested the rods, welding a 1/2 inch aluminum tube to a flat piece & the welded joint was actually stronger.

@Moonfleet41 2 года назад

Using the 'copper soldering method' is commonly advised as the technique for this... but in actual practice it's not that easy, copper melts almost 400c hotter then alluminium, and when ive used this for ally sheet it's really easy to melt the actually sheet metal at the same time.... the difference between the rod melt and the job its self melting is a very narrow 200c... and you have no colour changes as with steel to help you know it's hot enough... ""You're heating the rod not the job"" is the biggest criticism.. and usually made by those who have never tried this (Theory experts), so i would urge anyone to try this for yourself, it's pretty tricky to get right and not much room for error ! as im sure you found when you tried it.!

@krzaczekwegorz1135 3 года назад

Great video. Thank You 👍

@clivewilliams1406 4 года назад

Del, a good test but what it showed was that the aluweld is 'AS STRONG AS' the parent material. Your extra torque was not high enough to merit anything else and could be explained by various tolerances in the material/testing equipment/human application/phase of the moon etc. Also, it is wrong to state the the reason for the aluweld strength when it was purely speculation and not proven in any way - all you did there was to degrade your test by association. Leave the results to speak for themselves.

@clivewilliams1406 3 года назад

@fart locker In the very first instance I would check that you can't install a thread insert - Heli-coil is best and much stronger than the original thread. If there is no way that the thread insert can be used, say where the hole/boss has broken away from the casing then the only solution is to fill the casing back with a weld material. Due to its low temperature melting point Alumiweld can be considered either as a low temperature aluminium or no better than a high temperature solder. If I had to rely on the Alumiweld then I would fill the hole and drill it out for a Heli-coil to get the very best fixing in the poor metal - I certainly wouldn't solely rely on the threads in Alumiweld, and then look to inserting a stud rather than a bolt to reduce the possibility of the thread failing due to being worked too often. I assume that the stud stripped out the thread due to excessive torque tightening?

If you want to repair a M6 hole, you can use a 1/4 inch BSF bolt. The pitch is the same, but it is slightly thicker.

@itruns Год назад

Made an error getting a busted bolt out of carb boot/manifold. Left part of the bolt and ez-out tool that busted off in the head as well. Tried to drill and tap through, and the drill went sideways enough that the hole was too close to the head's edge. A mess! I have to fill the hole, but it will be part of the area refilled will be part if the retapped area. Was thinking fill it with silver solder or what you did, but I feel like I have one more chance, and I need experience before I destroy this.

@sharonsharon2604 3 года назад

Aluminium is annealed by quenching while its very hot. I think that you just let it air cooled slowly, and therefore tempered it. This is why the chipping and torque readings were different. The experiment should have included proper annealing of the piece.

@travisk5589 Год назад

@colingeer479 4 года назад

The type of swarf that comes away when this alu-weld is drilled reminds me of brass more than steel, as steel can create long spirals if conditions are perfect. Maybe this indicates it's closer to brass in it's properties? Anyway, interesting test, thanks Delboy.

@rickmarkgraf2617 4 года назад

Guess you learned your lesson, as we all do. I always view the bolt in my mind' s eye, imagining in advance the direction it needs to turn to tighten or loosen. Never fails me. I do the same when trying to spell a word correctly. I just see it in my mind's eye the way it is in a book, and then read out the letters. I don't know how others do this, but its a trick that never fails me. My wife plays word puzzles, but constantly asks me for spelling. 🙂

@Moonfleet41 4 года назад

@@rickmarkgraf2617 One of the reasons why sump plugs are so commonly stripped is that they're just about the only bolt we fit upside down!... think about it, the vast majority of bolts fit downwards and sideways!!

@rickmarkgraf2617 4 года назад

@@Moonfleet41 No argument. Just saying that my trick works because a picture works better for me. In my mind, the orientation of the bolt doesnt matter. The bolt is the bolt, and it only turns one way to loosen. Verbal tricks like lefty loosey may complicate. BTW, I learn from, and enjoy your vids. Grateful.

@woodatwork6927 4 года назад

Very interesting! I’m more impressed by how well the alurod bonded to the parent metal. I thought it would spin inside the larger hole before it would strip. You mentioned at the end that you’d prefer a stainless steel insert over retreading. How concerned are you about dissimilar metal corrosion? It would also apply to SS bolts threaded into aluminium.

@TimsWorkshopTJY 3 года назад

Tried it but it doesn't melt like your did? Mine was clumpy like it didn't get hot enough? I used a propane torch used for plumbing. I don't think it puts put enough heat. What kind was yours?

@Moonfleet41 3 года назад

Just a regular propane torch like yours, but you do have to heat the job up thoroughly, clumpy means the parent metal isn't hot enough!

@dennisrobinson8008 2 года назад

I replicated the test. With Propane or MAPP you have to have the flame close up on the material/hole. It takes 1-6 minutes to heat the material. The rod will flow when you touch it to the material if it's hot enough., Once it's flowing, keep material hot with indirect heat and keep filling the hole with rod. I swirl it around in this hole situation. If it "clumps" it just didn't get hot enough or the flame is melting the rod. The right way is the material or area being corrected needs to have the heat in it to melt the rod. Cleaning the area with brass or stainless steel brushes is super critical.

Stronger than the parent metal is a subjective claim. I have aero grade aluminium that is tough as hell. If I want silly strength, I will drill and tap oversized then Helicoil just as you suggested and use thread locker on the Helicoil.

@Moonfleet41 2 года назад

Regarding Helicoil, have you ever tried Wurth Time Serts? They're a solid stainless tube that can be red threadlocked in and way stronger than a helicoil, if it's strength you need. Just thought I'd pass it on in case you didn't know, but excuse if you have.

@kaylebdunwoodie9079 2 года назад

I have a zero turn mower hydro gear pump (aluminum housing I believe). The release valve threads (to release hydro release to put in neutral in case of towing or engine problems) have been stripped smooth half way down the threads. Drilling an tapping bigger isnt and option and neither is heli coil inserts ect. I'm wondering if I could heat the entire piece up and partially fill and retread the threads with these brazing rods? Do you think they'd hold a pressurized pump seal? I believe 3000 psi is the max pressure. Or at least that's what the pressure hoses coming off the pump have printed on them.

@Moonfleet41 2 года назад

To be honest, i know nothing about such pumps Kayleb, and have only limited experience with high pressure hydraulics. All i would venture to say is "was the stripped thread blown out by pressure or cross threaded by clumsy assembly?".. the answer to that should be enough to decide. With such high pressures it can be obviously dangerous if things like seals are not totally secure to the manufacturer specification... So it's a safety risk and only you can decide if you're willing to take that chance..! I hope that helps you in some way mate. Good luck with it.

@assessor1276 4 года назад

Very interesting Delboy - well done! Just one small correction: there is no such thing as “torque pressure”. Torque means force x distance (hence lb-ft or N-M) while pressure is a force / area (so you get lb per sq. inch, etc.). It may seem like hair-splitting, but incorrect terminology is confusing and spoils the effect of your otherwise excellent work.

If it stripped the aluminum out once, it’ll probably happen again. Stainless thread inserts are my go to.

@Moonfleet41 4 года назад

The results of the experiment were interesting, as you saw, and the material stayed plugged in the hole, some argue that a helicoil, or Time Sert, is only held in my the same parent metal that stripped in the first place, so it's always a trade off aye?!

@ippielb 4 года назад

Moonfleet41 yeah I completely agree but you’d also have to think about drilling the hole larger will give you a bigger diameter and more parent material to hold onto, which in turn should equal more holding force. I’d like to see a comparison.

@dennisrobinson8008 2 года назад

@@ippielb Basically it works. I tested it. BMW engine blocks have a issue with threads pulling out. It pulls out at between 40-50 ft-lb. I had to do the same test. A threadsert actually pulled out. Drilled out the hole oversize as on this video, filled it with HarborFreight "alumiweld" product. Angle grinder flat, drilled and tapped and a new insert. I was able to get 55 ft-lb on the torque wrench test, so as Delboy shows it will hold the torque at or slightly greater than the parent metal.
