Always love Lily. She is such a laid-back dog, enjoying her golden years. Thanks again Darren for sharing your garage with your faithful subscribers. Keep up the great work. Chuck in NE Kansas
you all probably dont give a damn but does anybody know of a tool to log back into an Instagram account? I was dumb lost the login password. I appreciate any assistance you can give me.
@Emmitt Sutton Thanks for your reply. I got to the site thru google and I'm waiting for the hacking stuff atm. Looks like it's gonna take a while so I will reply here later with my results.
When I was young and couldn't buy expensive tools, I purchased an angle grinder from Freds Dollar store. I have had it for about 12 years and still use it regularly. Also bought a Freds brand Dremel tool that is nearly 20 years old. It was a gift for my dad that I bought when I was making minimum wage. He used it about 15 years and bought a new Dremel. I asked him if I could have it back and have been using it for 3-4 years. LOL
Mustie Your you tube channel is awesome. I like how you include your viewing audience in your videos. I also appreciate how your willing to help others and show others how to repair things. Great job!!! Since I found your channel I learned how to repair things.
I own 2 of these grinders and worked with 8- 4 and 5 inch styles in my career, the big issues with mine have been fraying cords and worn brushes, i have never seen one slip like that on it's shaft. This trigger type of switch makes it safer than permanent "ON" type grinders, so if it does bind you release your hand and the power dies, they don't tear out of your hand and flip out on the floor waiting to be unplugged. I take my safety guards off for sight line only, the guard does get in the way when you are trying to be precise , just make sure you wear a face shield for when the disk does explode on you. I've never had a disk explode and rip through a T shirt and have taken many an exploded blade to the chest with only bruises never a laceration from one.
Mustie1 I watch pretty much every video you have made I find them enjoyable and interesting. I myself am a ASE master technician and was vw tech , have huge passion for vw's thats what brought me to your channel a long time ago, and on weekends I am always messing with mowers and small engines and scooters that didn't run been sitting it's always cool to bring things back that were left for dead , your videos are great! You do a good job. I often find myself telling other gearheads about your channel all the time . Keep up the good work brother.
Excellent fix. Most angle grinders die because they are not well greased from the factory. The grease is smeared in, often not even reaching the moving parts. The only ones I've seen that are not prone to this are Makita and Flex. I always open the gearbox of a new grinder and check the grease. I used a grinder without the guard for awhile until it bit me, and when angle grinders bite it hurts.
I had the same failure on the same grinder. Set it up in the drill press and drilled a hole at an angle that went through the gear and shaft. Drove in a roll pin. I'm still using it a couple of years later... Just my $.02. Nice work, Mustie! Always like your videos!
I had a Dewalt I bought at a garage sale for $10 that did the same thing the first time I used it at home. I used JB Weld and it has held thru 4 snowmobile trailer builds & 2 refurbished trailer builds. If it starts slipping I will deploy your method.
Just a few hours ago I loaded in the Mobile 1 blue grease in my DeWalt DC 410 and reassembled it. Crunchy switch needed cleaned out and so I just went ahead and did the whole maintenance top to bottom. Used Gunk to clean out the old gear grease...worked great. Intermittent switch is fixed and I have spark, a lot of spark! Great video, thanks Mustie.
I am a tile setter and use Dewalt angle grinder, I always use the guard, I saw a friend get a nice small piece of stone tole kick back and went 1/4 inch inside his arm. I never tell people to take the guard off for that reason. I had a Makita angle grinder and it started slipping after 9 years of constant use. They just replaced the assembly and its cheaper then buying a well made angle grinder.
I remember years ago, too young to use a grinder, I was alone in my father’s workshop and I used it just for a moment to cut open a transformer. Just as I cut through the steel lamination, the wrong way as mustie demonstrates, into the copper, making the grinder bind, which SHOT down into my thigh in the blink of an eye. Fortunately, I wore a long t-shirt that day and the grinder “ate” it, essentially halting it. Be very careful with power tools people, get proper training and ALWAYS use protective gear, as unwieldy it may be.
Great job, Mustie. It looks like that grinder will live to grind another day. I like you dog. My golden lab holds things like that in his mouth as well. Labs are great dogs.
It is very rare that you absolutely need to take the guard off any power tool. If you do, you better be willing to take the risk of only be able to count up to ten, if you take off your socks. On those rare occasions, do the dangerous stuff, then put the guard straight back on. You paid good money for the guard and its there for a reason, so you might as well get your money's worth.
Have one just like it. Good to know what to watch out for and how to fix it. Good teaching moment on guards! I admit to being tempted so many times to get rid of it but somehow the little guy in my head said .. “no!”.
Its funny, right after i watched this video i was watching an episode of Roadkill and they were cutting a Corvette frame in half with the same grinder and had no guard on it. The thing kicked back landed on the floor, bounced up got caught in the guys pants leg and cut through his sock. He only got knicked in the shin but it coulda been a whole helluva lot worse. Keep Safety Guards ON!!! They're there for a REASON!!!
I learned the hard way without the guard. I had sanding disc in and dropped it, grinder hit the floor and disc came back up hit 5 inches above my ankle. Wasn't a pretty picture, hurt and bled for sometime. I ended up putting fake skin on to replace mine to heal. From now on guard stays on
Bought myself an off brand grinder with some Christmas money early in the year. Put it a tool bag and on a shelf. Later when moving the shelves, I commented to my wife to take the bag off so as not to hurt the new grinder... of course, she thought that was nonsense, and the bag crashes to the garage floor. Had the guard not been installed, the disc and even the arbor may have been badly damaged. The guard was relatively easy to fix.
As a blacksmith i agree: Leave the guard on. It should only come off when in tight spaces, and should go straight back on when u are done. There are so many dangers without. Fingers getting caught on exposed disc, disc blowing up in your face, if u drop it, it will take off on the ground, esc.
If you have a cutting disc on and you drop the grinder, replace disc and throw the old one away. You will never know that it has cracked until it flies to pieces.
The burned in numbers on the underside of the yellow plastic housing tells me that was sold as a refurbished unit. But I would GUESS that Dewalt would have replaced all that stuff with new if that's why it was returned. I'd set that aside for lighter duty stuff, like cutting with a diamond wheel where you aren't forcing down on it but just plunging in sideways.
I bought from a Black & Decker center in Mahanattan back in the 1980s - the tools always looked pretty new. Now I buy refurbished stuff from CPO a lot and yesterday I got a dewalt blower. Except for some scuffs on the overmolded handle it again appeared as new.
There was a Tools Direct store in our local outlet mall. Sadly for me, they closed. It actually was the outlet store for Home Depot returns and discontinued items. I bought an abrasive chop saw and a couple of other items at a good discount. Maybe it was a good thing they closed; I would have gone bankrupt if they stayed open.
I have that same grinder, oldest one I own, no issues here, except I have had to replace the cord due to the insulation crumbling off, probably from getting oily too many times.
I remember doing my abrasive wheel course many years ago and they showed a video of a cutting disk exploding with and without the guard on. The jell dummy didn't look very well after the non guard disk broke. Angle grinders are more dangerous when you are comfortable using them!
As a teenager I worked at a power tool repair shop. Doing things like this was what we did, new switches, new cords mostly. We would have ordered a new gear assembly. Sadly there are no power tool repair shops anymore execpt in this guys garage
A lot better than the carb for a Stihl 015 that I recently rebuilt. The cobbler who owned it before me glued every gasket and diaphragm on the carb. They had also epoxied every bolt on the saw. I had to drill lots of bolt heads off.
It was hard worked I guess and caused the shaft to eventually heat up and kind of shrink. You repaired it and kept it alive though mustie. I'd do the same thing myself. Great video mate
Lots of seniors watch your Channel, so glad u keep it clean(er).Another Five Guys hamburger huh! Soon you will need to rename the company six guys or 6 guys and a dog.
I like my dewalt because its lighter than the milwaukees. Easier on brushes too. Iv never had a problem with it yet. Its scary how many utubers dont know how to operate a grinder. I dont use them without the guard either. The sparks burn up your clothes. Iv had shards in my eyes twice back years ago. Never had one since I started wearing a full face shield
Simon from the uk here.... Was that lilly with her nose in that cup? Lol 😂Great video my Twin Brother I’ve never had a grinder do that before,I also think it was the previous owner abusing it. Now we know what is inside one of these. Your a great teacher and we have fun along the way. Catch you on the next one 😉😀🐕
I've had to fix my AEG angle grinder 3 times! One time the motor brushes wore out and I had to modify some to fit. Another time a motor bearing collapsed. The other thing was the switch, it was a 2 pole switch but one pole failed so I bypassed it and use it on one pole. I use the diamond discs which don't shatter.
You might be surprised, I bought a HF angle grinder for the guys at work to abuse. And abuse it they did. 13 or so years later it's still going strong although the gears sound dry now and had to fix the cord once.
They actually sell 2, 1 the cheapy you mentioned, but another they call 'Heavy Duty' w/a paddle switch that actually works good, have had one of them for many yrs. w/no problems, although I have a large Milwaukee I pull out for big jobs!
I love making things work better. I bought a Bosch palm sander where I knew the sandpaper would slip off. There was a spring loaded clip on the front and a lever on the back. I took it apart and found I could move the spring on the front clip to apply more pressure and now have a great sander. I had bought it for $20 where it usually sold for $50. As far as the guard on the grinder, DEFINITELY USE THE GUARD. One time I used a grinder and for some reason couldn't figure out how to put the guard on, even though I had done it so many times before. I was using a cut off wheel to cut some steel and the wheel broke. Luckily I was wearing a pair of gloves and wasn't cut, but hurt like hell. When I changed the wheel I was able to put the guard on. Still don't know why I couldn't figure it out the first time. The wheel could have very easily hit me in the face. USE THE GARD. Thanks for sharing Mustie.
Had the same problem with Dewalt grinder, only Dewalt tool that has failed me. Replaced it with the harbor fright Hercules grinder, still running good after a year.
I agree with you regarding grinder gaurd removal. I like my fingers (I play guitar) and eyes so i think taking it off is not smart. It never seems to get in the way of what i use mine for .
i have a variable speed METABO that i have had for nearly 15 years , works well to this day always used for any of my car restoration work , the variable speed alows for better control and i ALWAYS use the disc sheild !
Terry Davies We just bought a new metabo for the shop. What a disappointment. Uncomfortable in the hand and poorly located switch. The mandrel is way too long to allow anything other than edge grinding. It does have good power but overall it just lacks that fit you want in a tool used throughout the day. Keep the old one.
I'm surprised they went through that much trouble to fix it the first time, it must have been used on a farm. :>) Pretty neat that there's not much to the little guy.
I have a Skill 3/8 variable speed with reverse drill that did the same thing, so I did the same fix you did on your angle grinder. That's 30+ years ago still use it to drive screws in with.
I used to use that brand of flap disc. I tried the Walter Abrasives flap disk and found they cut better and last far longer despite having less total thickness of flap abrasive. Try em you'll like em.
There's a lot of poorly designed safety guards out there, but the one on a grinder usually is just what the doctor ordered- but I do remove it, in one circumstance. If you're using a wire wheel, the brushes of the wire wheel can get pulled out of shape, far enough to grab the edge of the guard. Doesn't kick, but cuts the wheel down right now. I've had it eat a wire wheel in a matter of seconds, and they ain't givin' em away. Once the wheel comes off, the guard goes back on. And, yes, I have had a nasty strawberry across my stomach, from a 7" wheel that grabbed my shirt, so generally only do this with the 4".
Not just that - but now am reminded of my Black & Decker hand grinder that has a bad power switch. I bet I CAN FIX IT! (been plugging in to turn on for years! Not after today, lol)
Mike .R. black and Decker professional, predecessor to DeWalt. Had a side grinder and a 3/8 hammer drill both lasted for years and years. The grinder finally just literally blew up and the drill had a major melt down. Used both in my tile business.
The only rare instance I know of for taking off the guard is when you're fitting a disk onto it that's larger than what the guard is supposed to fit. Obviously, it makes more sense just to get the proper size cutting disk in the first place, but sometimes your only option is to work with what you have on hand.
I’ve seen at least 2 guys at work run that brand with a cut off disc the wrong way and end up at the ER. After working with hack saws for a while, the rest of the crew learned how to correctly and safely operate a grinder.
Thanks now I know how to fix my dewalt 4.5 grinder other than throughing them in the trash when it starts slipping. I have throwed away 5 or 5 because of that.
Yes, the ring gear is most likely powdered metal, the pinion gear is "cut". Welding powdered metal is very difficult; once it liquefies, it only solidifies correctly under pressure. Those parts are heat sintered at factory, the shaft is tapered. It was stalled a few times too many, and the hole in the ring is wallered out. Tap out the shaft, and add some metal (MIG) then re taper on lathe. Dry, clean arbor press fit ring HOT, fully supported center underneath. Recover the space PO ground for weld with wavy (thrust) washer(s).
Wow, read through the comments after posting one of my own. 18 minute video with 17.5 minutes of wrenching and half a minute of pupper. Half of the comments are about the dog, including mine, and all are positive. Never work with kids or animals...
I borrowed a grinder from a friend one time working under a car, it didn’t have a guard and I got into a bind where the disc cut into my finger....down to the bone. Funnily enough it didn’t bleed at all, the skin had kind of melted. Still have the scar to prove it, that was nearly 30 years ago. Have never used a grinder without a guard since.
I have a relative who used one at work with the guard removed, the cutting disc exploded and buried half into his face, he is now blind in the right eye with permanent numbness to that side of his face. Nothing to mess with.
You have a lathe , chuck it up , and clean that weld ! Now disassemble , nick the shaft and the gear , reassemble . Loctite or re weld your choice . The lathe's the key ;)
I know what you mean about someone taking a guard off a grinder. I was given a big old Bosch grinder and the former owner now deceased had taken the guard off of it. lt has so much torque i am kind of afraid to use it . Currently trying to see if I can find a guard for it, its the only safe way to use one.
I always use a diamond abrasive disk in my grinders. It is a little more expensive, but I have never heard about one exploding and throwing parts. I have also never had them kick back. I still use a guard, to protect myself from the sparks.
I used to work industrial safety, sometimes the maintenance contractors would show up with angle grinders without the guard. Give 'em a eye roll and send their asses back to the trailer for a new grinder.
I can hear it now. You didn't use factory Moly grease on the gear set.. Oh no!!! It's an old Dewalt grinder folks. Nice to see him getting some more use out of it... Great fix...
Good save. I'll bet they have a weakness from the factory that way. I'd more expect the gears to strip. FWIW I couldn't imagine blasting spray paint on my tools, but that's how I am. I like my stuff as clean and neat and pretty as I can keep it.
Always love Lily. She is such a laid-back dog, enjoying her golden years. Thanks again Darren for sharing your garage with your faithful subscribers. Keep up the great work. Chuck in NE Kansas
you all probably dont give a damn but does anybody know of a tool to log back into an Instagram account?
I was dumb lost the login password. I appreciate any assistance you can give me.
@Koda Joaquin instablaster =)
@Emmitt Sutton Thanks for your reply. I got to the site thru google and I'm waiting for the hacking stuff atm.
Looks like it's gonna take a while so I will reply here later with my results.
@Emmitt Sutton it worked and I actually got access to my account again. I am so happy:D
Thank you so much you saved my account !
@Koda Joaquin happy to help :)
When I was young and couldn't buy expensive tools, I purchased an angle grinder from Freds Dollar store. I have had it for about 12 years and still use it regularly. Also bought a Freds brand Dremel tool that is nearly 20 years old. It was a gift for my dad that I bought when I was making minimum wage. He used it about 15 years and bought a new Dremel. I asked him if I could have it back and have been using it for 3-4 years. LOL
When it quits send it to AvE, that would make for an awesome teardown video
Mustie
Your you tube channel is awesome. I like how you include your viewing audience in your videos. I also appreciate how your willing to help others and show others how to repair things. Great job!!! Since I found your channel I learned how to repair things.
Nicely done!
how can you say this??? he didn't even baptise it in evaporust!
Repeating another viewer's post..........."Best shop teacher I ever had." Thx.
I own 2 of these grinders and worked with 8- 4 and 5 inch styles in my career, the big issues with mine have been fraying cords and worn brushes, i have never seen one slip like that on it's shaft. This trigger type of switch makes it safer than permanent "ON" type grinders, so if it does bind you release your hand and the power dies, they don't tear out of your hand and flip out on the floor waiting to be unplugged. I take my safety guards off for sight line only, the guard does get in the way when you are trying to be precise , just make sure you wear a face shield for when the disk does explode on you. I've never had a disk explode and rip through a T shirt and have taken many an exploded blade to the chest with only bruises never a laceration from one.
Mustie1 I watch pretty much every video you have made I find them enjoyable and interesting. I myself am a ASE master technician and was vw tech , have huge passion for vw's thats what brought me to your channel a long time ago, and on weekends I am always messing with mowers and small engines and scooters that didn't run been sitting it's always cool to bring things back that were left for dead , your videos are great! You do a good job. I often find myself telling other gearheads about your channel all the time . Keep up the good work brother.
thank you
Excellent fix. Most angle grinders die because they are not well greased from the factory. The grease is smeared in, often not even reaching the moving parts. The only ones I've seen that are not prone to this are Makita and Flex. I always open the gearbox of a new grinder and check the grease. I used a grinder without the guard for awhile until it bit me, and when angle grinders bite it hurts.
You are becoming a video machine!!! It is great to see a new one every day or so.
I had the same failure on the same grinder. Set it up in the drill press and drilled a hole at an angle that went through the gear and shaft. Drove in a roll pin. I'm still using it a couple of years later... Just my $.02. Nice work, Mustie! Always like your videos!
I repaired my Bosch, bad bearings, repacked the grease in the head. Now it will work for years like your Dewalt. Nice fix on the Dewalt.
I really like this kind of video-please do more. But DONT stop the VW fixes.
Mustie Vaudeville....He does a good range o' fixes... Entertainment for all!
I had a Dewalt I bought at a garage sale for $10 that did the same thing the first time I used it at home. I used JB Weld and it has held thru 4 snowmobile trailer builds & 2 refurbished trailer builds. If it starts slipping I will deploy your method.

I think the dog wants to go to the pub.
Thoroughly agree with the guard on the grinder advice.
I don't think Loctite, would hold with a load on it. It's only for static situations . I like this video, a teachable moment THANKS .
I remember years ago, too young to use a grinder, I was alone in my father’s workshop and I used it just for a moment to cut open a transformer. Just as I cut through the steel lamination, the wrong way as mustie demonstrates, into the copper, making the grinder bind, which SHOT down into my thigh in the blink of an eye.

Be very careful with power tools people, get proper training and ALWAYS use protective gear, as unwieldy it may be.
This why battery powered grinders are better. They have protection (stopping the blade), if the disk gets stuck.
Safety third.
@@MiiSbk Yes its called no torque
Learn something new everytime I turn on the Mustie1 Tv Channel.............Keep up the good work!
I learned a lesson about taking the guard off mine, I was cutting up some junk and lost my grip..went right into my left knee..keep the guards on.
Jeez, another foot or two and coulda took your life.. have frank and beans spread all over the place...
I've been in industrial maintenance and repair for over 25 years. I've never seen a Dewalt 4 1/2 grinder fail in that manner. Usually the gears strip.
Great job, Mustie. It looks like that grinder will live to grind another day. I like you dog. My golden lab holds things like that in his mouth as well. Labs are great dogs.
Thank you for sharing your amazing video, God bless you and your family

I can't count to 21 unless I'm naked.
Nice fix! Like a surgeon! Also taking the time to grind the weld for clearance in the gear box. And the dog… adorable!

As a teenager I worked at a power tool repair shop. Doing things like this was what we did, new switches, new cords mostly. We would have ordered a new gear assembly. Sadly there are no power tool repair shops anymore execpt in this guys garage
I'm watching in June of 2021and there's your beautiful girl at the end. R.I.P. Lily.
A lot better than the carb for a Stihl 015 that I recently rebuilt. The cobbler who owned it before me glued every gasket and diaphragm on the carb. They had also epoxied every bolt on the saw. I had to drill lots of bolt heads off.
Always love watching you wrench on stuff, keep it up Mustie1
It was hard worked I guess and caused the shaft to eventually heat up and kind of shrink. You repaired it and kept it alive though mustie. I'd do the same thing myself. Great video mate
Nice De Walt grinder repair Mustie, marking red 👍
Im surprised it wasn't the carb....
Clogged exhaust was my guess
I thought it mightve been some fouled plugs.
andrew.. you see how those comments didnt get you ?? lol,, not regular Mustie viewers :O)
Andrew Poulin I thought it had no compression!
The best teacher , which we are learn everything. Thank you Mister Mustie. You are qreat.
I have one just like that bought it new about 17 years ago still works great
Lots of seniors watch your Channel, so glad u keep it clean(er).Another Five Guys hamburger huh! Soon you will need to rename the company six guys or 6 guys and a dog.
For anyone not using a guard, it's only a matter of time before it bites you.
If you've ever had a disc explode on you, youll never not use a guard again, scares the crap outta you
Brandon Lund Yes indeed. I put mine back on.
Well, I use gloves since my last bite...
I like my dewalt because its lighter than the milwaukees. Easier on brushes too. Iv never had a problem with it yet. Its scary how many utubers dont know how to operate a grinder. I dont use them without the guard either. The sparks burn up your clothes. Iv had shards in my eyes twice back years ago. Never had one since I started wearing a full face shield

I was dying with the filler at the end. He looked so sad that he couldn't get the last of it out. But he wasn't letting that cup go. Great times
I've had to replace the gears on this same kind of grinder that I also bought used work like new now great video keep it up
Had the same problem with Dewalt grinder, only Dewalt tool that has failed me. Replaced it with the harbor fright Hercules grinder, still running good after a year.
I agree with you regarding grinder gaurd removal. I like my fingers (I play guitar) and eyes so i think taking it off is not smart. It never seems to get in the way of what i use mine for .
At least you could fix it. Had a much older Dewalt, gears chewed up, had to toss it in the trash.
i have a variable speed METABO that i have had for nearly 15 years , works well to this day always used for any of my car restoration work , the variable speed alows for better control and i ALWAYS use the disc sheild !
Terry Davies We just bought a new metabo for the shop.
What a disappointment.
Uncomfortable in the hand and poorly located switch.
The mandrel is way too long to allow anything other than edge grinding.
It does have good power but overall it just lacks that fit you want in a tool used throughout the day.
Keep the old one.
I'm surprised they went through that much trouble to fix it the first time, it must have been used on a farm. :>) Pretty neat that there's not much to the little guy.
Nice fix there , also a very happy puppy at the end with the milkshake cup!
I think your doggie likes "5 guys"...Excellent Repair Job!!! THANKS FOR MAKING the video!
I would say that mustie is the “Bob Ross of mechanics” whatta ya say?
I normally have to chenge brushes on them . Good one
We need the beaver. Thanks for the video Mustie.
All I could think of is putting it on the lathe. Thanks for sharing.
I have a Skill 3/8 variable speed with reverse drill that did the same thing, so I did the same fix you did on your angle grinder. That's 30+ years ago still use it to drive screws in with.
I used to use that brand of flap disc. I tried the Walter Abrasives flap disk and found they cut better and last far longer despite having less total thickness of flap abrasive. Try em you'll like em.
17:37 "Can't I enjoy my milkshake cup in peace?" Haha
You may have me convinced to put my guards back on. I always liked them off so I got a better view of the work.
The dog isn't going to release that cup, unless it's refilled.....good one Mustie
I couldn't figure out what I was seeing at the end. Then I realized it was your dog. :)
Score one for the good guys!
There's a lot of poorly designed safety guards out there, but the one on a grinder usually is just what the doctor ordered- but I do remove it, in one circumstance. If you're using a wire wheel, the brushes of the wire wheel can get pulled out of shape, far enough to grab the edge of the guard. Doesn't kick, but cuts the wheel down right now. I've had it eat a wire wheel in a matter of seconds, and they ain't givin' em away. Once the wheel comes off, the guard goes back on. And, yes, I have had a nasty strawberry across my stomach, from a 7" wheel that grabbed my shirt, so generally only do this with the 4".
..ahh, something to have with my morning coffee..lol
you said it brother, haha
Not just that - but now am reminded of my Black & Decker hand grinder that has a bad power switch. I bet I CAN FIX IT! (been plugging in to turn on for years! Not after today, lol)
Good way to start the daily grind!
Mike Cady ha-haaaaaaaa!!! Good one
Mike .R. black and Decker professional, predecessor to DeWalt. Had a side grinder and a 3/8 hammer drill both lasted for years and years. The grinder finally just literally blew up and the drill had a major melt down. Used both in my tile business.
Milwaukee red on a DeWalt? Sacrilege! Just kidding. Nice job fixing it.
The only rare instance I know of for taking off the guard is when you're fitting a disk onto it that's larger than what the guard is supposed to fit. Obviously, it makes more sense just to get the proper size cutting disk in the first place, but sometimes your only option is to work with what you have on hand.
I’ve seen at least 2 guys at work run that brand with a cut off disc the wrong way and end up at the ER. After working with hack saws for a while, the rest of the crew learned how to correctly and safely operate a grinder.
Thanks now I know how to fix my dewalt 4.5 grinder other than throughing them in the trash when it starts slipping. I have throwed away 5 or 5 because of that.
still working good
Yes, the ring gear is most likely powdered metal, the pinion gear is "cut". Welding powdered metal is very difficult; once it liquefies, it only solidifies correctly under pressure. Those parts are heat sintered at factory, the shaft is tapered. It was stalled a few times too many, and the hole in the ring is wallered out. Tap out the shaft, and add some metal (MIG) then re taper on lathe. Dry, clean arbor press fit ring HOT, fully supported center underneath. Recover the space PO ground for weld with wavy (thrust) washer(s).
Thanks
Wow, read through the comments after posting one of my own. 18 minute video with 17.5 minutes of wrenching and half a minute of pupper. Half of the comments are about the dog, including mine, and all are positive. Never work with kids or animals...
INSTANT GRIN every time!
I borrowed a grinder from a friend one time working under a car, it didn’t have a guard and I got into a bind where the disc cut into my finger....down to the bone. Funnily enough it didn’t bleed at all, the skin had kind of melted. Still have the scar to prove it, that was nearly 30 years ago. Have never used a grinder without a guard since.
I have a relative who used one at work with the guard removed, the cutting disc exploded and buried half into his face, he is now blind in the right eye with permanent numbness to that side of his face. Nothing to mess with.
“I’m tired of waiting, let’s get the welder”
I wish I had a teacher like Mustie in HIGH School!
Don't forget your face shield for extra backup
Hey mustie, locktite makes a wicking thread locker, I believe it’s green. Useful for many applications.
You have a lathe , chuck it up , and clean that weld ! Now disassemble , nick the shaft and the gear , reassemble . Loctite or re weld your choice . The lathe's the key ;)
l tried, would not fit
I know what you mean about someone taking a guard off a grinder. I was given a big old Bosch grinder and the former owner now deceased had taken the guard off of it. lt has so much torque i am kind of afraid to use it . Currently trying to see if I can find a guard for it, its the only safe way to use one.
Great Vid, Mustie, that love the black lab. Got one almost like it. Mine's an American Field Lab...(The Skinny kind)
Thought you were going for a Bob Ross quote when you were painting the gear. “We are having fun here”. 🤣
I always use a diamond abrasive disk in my grinders. It is a little more expensive, but I have never heard about one exploding and throwing parts. I have also never had them kick back. I still use a guard, to protect myself from the sparks.
I used to work industrial safety, sometimes the maintenance contractors would show up with angle grinders without the guard. Give 'em a eye roll and send their asses back to the trailer for a new grinder.
The bearings always go bad for me. Having 2 of the same is smart. You have one to go by to see what is correct. Thanxz
Good as new, well, it works!
I can hear it now. You didn't use factory Moly grease on the gear set.. Oh no!!! It's an old Dewalt grinder folks. Nice to see him getting some more use out of it... Great fix...
Nice fix, judging by the numbers etched in it, I'm guessing it was used and abused and probably repaired in an industrial environment.
Good save. I'll bet they have a weakness from the factory that way. I'd more expect the gears to strip.
FWIW I couldn't imagine blasting spray paint on my tools, but that's how I am. I like my stuff as clean and neat and pretty as I can keep it.
Best part might have been Lily's cameo at the end Thanks for sharing
