@@pedrobrandes8097 Cos those dislike are worth more than gold when it comes to truth, especially when your pushing a narrative. 81 million votes for biden, i doubt the dislikes would reflect that one. 🤔
@@pedrobrandes8097 they said it was because people were attacking creators and driving up dislikes. But it still makes no sense because creators still see the amount of dislikes, but now the public can't see it. unless you download some add on or extension
And what, this wouldn’t last enough time for him to make a new gear? I think you guys are so quick to say something won’t work you miss reasons why it could. This is gonna last longer than you think.
@@dougmcmillan2483 aluminum is a soft metal. If you were able to break that gear for whatever you were using it for under normal conditions, now you’ll be able to break it 10x as fast with an extra safety hazard on top of it if it doesn’t destroy your machine outright. Just buy a new gear and recycle the old one next time instead of wasting aluminum and everyone’s time.
This seems like an exellent way to utimately have to replace every other gear when these teeth utimately shear off and start rattling around the gearbox
Oh, it's 9pm you are with 12 employees planting 25 acres of Brussels sprouts ... rain is coming on the radar . One of the gears on our 6000 Holland jammed on a small rock and 3 cogs ripped . I in field mig filled the space and grinded the gaps ... 20 minutes and we were done planting before the rain around 2am . Next sunny day was 4 days later . You would still be waiting for the freakin' gear . Good day
@@gamayn2110 так чего люминию то отваливаться без нагрузки) Хотя, раз там так легко были просверлены отверстия и нарезана резьба, вполне возможно, что эта шестерня и не работает с какой либо нагрузкой.
As someone who has knowledge of different types of steel. I have a couple questions? So the bolts are aluminum? So don’t do this as a quick fix to keep the machine running till the replacement gear arrives. Shut the factory down and send everyone home until the replacement gear arrives?
This method is going to cause even more damage. The correct move is to simply wait for the replacement part. What will happen is the gear will turn maybe a couple dozen times (being very generous), the aluminum will sheer off and start destroying more gears turning this into an even more expensive size fix with even more wait time. If a single lathe being down is enough to cause a shop to shutdown it isn't a factory
Yep. This could get a negative number out of 10 for creating an environment ripe for galvanic corrosion using only mechanical fit between the gear tooth roots and chords, imbalanced, with an alloy that will s**t the bed like Amber Heard.
17 years as a metals,welding construction, drafting teacher. Smarter way would be to fill the gap with weld then take it to the lathe. And a horizontal milling machine. Did that to redo a broken gear from the H.S. woodshop 50 year old table saw. Was still working 15 years later..
@@jensandersen8270 I'm not saying such a thing doesn't exist, it's certainly physically possible to do, but seems expensive and unnecessary. I've seen many old table saws and none were driven by gears. A belt is just so much more common.
What you did it's doesn't fix it permanently because there is a difference between the resistance of steel (C45 ) and aluminum that why when you will assembly wheel gear with the other one the new model will get broken like the initial form before reparing .But I still I like what you did keep going . ❤
I can understand adding material by welding it. Its done all the time on low tolerance gears in poor countries. But casting aluminum is a whole other chapter
Please to anyone that may have the idea to do something similar… do not. First of all, you don’t repair hardened steal with aluminum. Second, the shape of a gear tooth is not at all a straight line (it is an involute of a circle). By doing what is done in the video, you will have poor engagement and it will heat up quickly until destruction. Finally, most of gears are hardened, it is not just molten metal gently cooled down. It is a special thermal treatment and surface treatment (sometimes even chemical treatment like nitriding). And it is done for a reason. In conclusion, buy a new gear, you won’t be able to repair it properly yourself without excellent technical knowledge and some good foundry equipment.
The original gear looks to me like cast iron rather than steel, and CI can be a brittle material. Perhaps if the damage arose from a one-off malfunction which will not be repeated, and the original gear was way stronger than needed, it might stand up. The aluminium will be somewhat reinforced by the steel studs, I guess. But it would have been better to use a higher tensile steel than hardware store machine screws.
@@beetelish If you can't find a replacement, that's really to only repair option. Best done by a machine shop who can cut gear teeth, but not impossible to do by hand, just a lot of work to get cut accurately enough, There's more to getting gears to mesh right than might appear. A pretty significant project for DYI, but not impossible. Once done, the whole gear should probably be heat treated. There isn't a lot of meat below the gears, so you'll likely need to heat treat. If it is a really old machine, you'll probably not be able to find a replacement unless it's a common well known brand. Probably take a lot of searching to find one, if you can. But worth trying. Depending on where this gear fits in drive system, it might be possible to run without it, but losing a speed range. This attempted fix might get everything to turn, but it won't hold up under any kind of load. And when this gear breaks, the pieces could end up messing up some other gears. If it's an otherwise good lathe, it's worth doing it right. I'd spend the money for a good machine shop to repair it and there's probably a couple ways they could do it. If I couldn't find someone with a good solution, I'd try what you suggest as a last ditch effort.
"Yo dawg! I heard you liked lathes so we installed a lathe in your lathe so you can machine while you machine while you make shockingly bad repairs to your lathe!"
