- Restoring a bench grinder. I was dropping off some trash at the dump when I saw this 8" bench grinder sitting by a dumpster. Let's see if we can give it a second life. See the links below for the parts and tools I used:

This tool costs about the same as a new bench grinder, lol.
I appreciate the project for the love of it though. A Black and Decker though? I'd have walked on by. In the UK they are considered cheap rubbish, at least nowadays. This looks like it was built in the 60s and might be worth the effort, since EVERYTHING was made properly back then.
My grinder has stopped working.... I turned it on one time in freezing cold weather and it started briefly and then died. Is that the motor giving up? Took apart and can't see anything immediate. The fuse is also good. There's no capacitor though, which is weird.
@@ArcanePath360 I agree, I wouldn't have grabbed a more modern B&D grinder but this one is pure quality. I like knowing that it was literally at the dump and now it's a very capable tool. Money-wise, I only bought some bearing grease and paint. It took a lot of time and effort but I learned a lot. For me, that's what it's all about. :)
As for your grinder, I'm no pro but it could be the switch. I'd try bypassing the switch, like I did, then plug it in and see if it comes back to life.
@@Mikeattempts Thanks, I'll give it a go. I agree. I spend months on projects that don't save any money, but as you say it's about learning and honing skills.
@@Mikeattempts Ok I tried the switch... I think it's a single pole, there's only continuity on one side when on. I thought both sides needed continuity to work and a single pole only shuts off one side, but whatever.... I bypassed anyway and nothing happened when I plugged it in.
@@ArcanePath360 With the switch bypassed and the grinder plugged in, give one of the grinding wheels a spin to see if you can get it going. If not, I guess it's an issue with the motor. Unless your grinder has carbon brushes that need to be replaced.
Bro even restored the original switch 😻
😄
I have the ten inch model. Exactly the same. They were made in the 1940's. Mine has the original paint. It has so much power it's a bit dangerous.
That's cool, I didn't even know there was a 10" model. Original paint too, that's rare! :)
Want to sell it? 🫂
A few things. The thing you called a commutator should be the centrifugal switch that breaks contact with the start capacitor once the motor is up up to speed.
The other thing? IMO never reuse sus bearings. Just don't. Bearings in an application like this just aren't that expensive to replace. And these for sure look like they were "rode hard and put up wet".
Ah, thanks for letting me know about the centrifugal switch! As for the bearings, I agree. Like I said in the video, I bought brand new bearings, but I couldn't find the exact width. I was afraid there'd be too much play with the new bearings, so I decided to clean and repack the old ones. They sound good when the grinder is running but I guess time will tell. Thanks for the comment!
That is a big phat beauty ol USA, I would rebuild that one before buying a new one.
Yep, built to last! After all this time, it only needed some cleaning and grease to come back to life. :)
That gear puller is certainly right for removing bearings. Nice overall job on the bench grinder. You lucked out on that one! :)
Thanks! I think there's a tool specifically for pulling bearings and evenly supports the face. Luckily these weren't tight, so the gear puller worked fine. :)
Good job.
Thanks! :)
Nice work
Thank you! :)
Really nice job and a great video detailing the restoration.
Thank you, I appreciate the positive feedback! :)
I totally agree! Fun to watch, too! :) I'm a new subscriber.
@@jt9498 Thanks for the sub! :)
the reason that your bearings darkened is because you used the " green simple green " in your ultra sonic. You gotta use the purple simple green, and it dosent darken the metal. Learned this the hard way on someones carburetor lol
Ah, nice to know, I didn't even realize there was a purple version of Simple Green!
Love it! You went all out on that one. Not many still using stick welding in their repairs....I'm old school too. When I find a bearing loose on a shaft, I add three center punch divots to the shaft to tighten things up, comes apart again with no heat. I made some fully adjustable rests for my old Baldor, see them at "Instructables- Beagles - New Rests for Bench Grinder" Cannot add a direct link here or my comment will be deleted.
I'm glad you liked the video! I put a lot of work into this grinder because I'm in it for the experience and to learn. I checked out your adjustable rest, those should last forever! :) Thanks for the comment.
That was simply amazing work. Good job.
Thanks, I really appreciate it! :)
Nice job. Only thing I'd do differently is the rust removal/prep. Evaporust and a nice bucket and lid is relatively cheap to buy once and be able to be reused for a year or two if you keep it covered. Its pretty amazing how much rust can be removed even in 4-5 hours if its a simple 1 day job.
Yeah, I've heard (and seen) great things about Evaporust but I haven't used it yet.
Great restoration
Thank you! :)
Beautiful !
Thanks! :)
Great find, I remember that my grandfather used to have one of those.
Yeah, it seems very capable, I think I might keep it! :)
@@Mikeattempts Keep it or give it to me :)
That grinder will outlast all new ones 10 time over.
@@grzesznypl I agree! It'll probably be nice to have around the shop since my other grinder doesn't have any grinding stones installed. :)
Great Job.
Thanks, I appreciate it! :)
Well done
Thanks, I appreciate it! :)
Very nice work.. see you on the next video...
Thank you! :)
Good job on this ;)
Thanks, I appreciate it! :)
I have a model like this except its english model 220 volts from my dad who died in 1983...changed the right side wheel ..cant get the left one out ..a y suggestions
One side of the shaft is reverse threaded so you can put a wrench on each side and tighten them both at the same time. It doesn't work as well when removing them because one side always breaks loose first. An impact wrench or maybe even an impact driver should do the trick. If you don't have any impact tools, you could put 2 nuts on the side that has been removed and tighten them against each other, then you should be able to hold the shaft while loosening the other side.
Ok thanks will try..ive know it since i was 10 years old..and im now 67..not one issue yet
@@garyallport18 Wow, that's impressive!
I would’ve lost interest 10 minutes in… but nice work!
Thanks, it was a fun challenge! :)
Lot of talking 😕
Mute the volume. 😉
