This video depicts the restoration process of a bench grinder with many years of history. According to the label on the machine, it was manufactured in 1973. The grinder has undergone years of challenging operation, with some functions and components damaged due to rust. I found it at a Japan recycle store and have an idea to restore it. Let's watch together!

Fabricating the end covers was my favorite part. They look great!
thank youu ♥
Dear god, the previous owner have never heard of maintenance. That was some great job young man!
thank you 🥰
Beautiful job Sir.
Great job on all of it.. I never ever saw a grinder with so much build up.
Thank you❤️
Fantastic job sir and a real pleasure to watch you work. Thank you!
thank youuu 😍
fabulous job. at the 27 minute mark, i started wondering.... where does someone find the time and energy to do a project like this? my next thought was.. where did i find the time to watch it? lol
Hey look at the new tools!🎉
thank you ^^ have a nice day
Nice work, but a tip about soldering to the cap: when you make this type of connection you should make a solid mechanical connection first, for instance run the wire through the eyes and bend it back around so it is mechanically secure, then solder. This helps with long term life of joints.
Bravo🎉 can't believe you pulled it off with the fiber glass
♥♥♥
Well done !
❤️❤️❤️
👍Missing splinter guards...
😅
Subbed - if only for the great work on the guards!
thank you ^^
@@hbrestoration well deserved! Terrific job.
Great job.....I like the way you fabricated the side plates. I only thimg missing is the eye safety shield. Great job.
thank you ^^
Agreed! Nice solution to solving the end plate dilemma
Nice! Now all you have to do is create brackets and plexiglass shields😁
thank you ♥♥♥
I do Marine repair and restore Muscle cars from one tech to another well done I love the freaking side covers kick ass dude love it @ My I make a suggestion when handling any start capacitors take a insulated screw driver and cross the terminals on the lead ins to discharge the cap before handling . They can store a lot of amps and discharge is you grab the leads. They can kill you if you get a big enough cap and zapped . Keep up the good work love it
❤️❤️❤️❤️
@@hbrestoration I know you are busy but I took time out of my day to give you a huge complement I never do that it is very rare because nobody can even type a simple thank you and show manners and respect anymore . A thank you would of been nice instead of lame hearts
I don’t think a direct short between terminals is very good for the capacitor…..
@@pomegranatepip2482 If you search on line for Electronic repair especially on Capacitors they will always tell you to discharge the cap before working on the circuit . Back in the day when tech fixed TVS it was standard procedure to discharge the cap or you could get electrocuted . Those caps back then stored a lot of charge . You are not damaging the cap all you are doing it discharging it . I am only talking about the bigger caps
@@pomegranatepip2482I've seen manuals tell you to do it.
Great video, good job, glad you didn't have to rewind the motor field windings, wonder what caused the big dent on the cast iron casing that you had to fill, would have thought that impact would have broken the cast iron frame, this grinder wanted to live on and by its condition was begging for a restoration, good job and i am a big supporter for restorations.
Thank youuu ^^
So that’s what screwdrivers are for.
Which one do you want to ask?
Well done - but resist the urge to grind on the side of the abrasive wheel. How do I know this ? 😱
I don't understand your question 😰
@@hbrestoration He's saying, dont use the side of the wheel. They are not designed for a side load and may shatter.
great job
♥
Excellent restoration! Beautifully done!
Thank youuu🥰🥰🥰
5:51, the weight of the rust is more than the entire bench grinder 🤣
😂
I think this Hitachi grinder would have been in worse rusty shape if they had actually EVER cleaned the machine one time.
Ya did you see that it still had lots of good paint under the rusted grinding grit? The best part of the show was him chipping off the slag!
Good Job.👍👍👍👍👍
😍😍😍
Gran trabajo 👍🏻
🥰🥰🥰 thank youuu
amazing ❤
🥰🥰🥰
OK! Who are you and what did you do with the guy who reworked the yellow grinder? New tools! A sandblaster! Where'd you get that fancy new tag? Cool color paint, but dont be afraid to put on more,more,more of it.
The yellow one I'm still using in every video 😅
Ficou muito top 👍👏👏👏
Thank you 🥰🥰🥰
Przepięknie jest odrestaurowana ta szlifierka Kołowa Pozdrawiam serdecznie 👍👍👍👍
Thank youuu🥰🥰🥰
Beautiful job
Thank youu 🥰🥰🥰
Красиво. Только работа к сожалению дороже стоит чем станок.😊
Великолепно!
Is all that stuff he's chipping off the residue from the grinding disks?
yes, it includes iron filings
amazing
🥰🥰🥰 thank youuu
наждак ні кшм лайк
Le falto la tapa de abajo.
Хорошо придумал, из стекломата боковую крышку, надо взять на вооружение!
из стеклоткани лучше.
Я бы из жестянки сделал, проще и быстрей. С текстолитом возни...😊
Bạn mua cái tem đó ở đâu vậy
Có máy in bạn nhé
What was the rating of the capacitor?
Capacitors only need to be measured with a meter
@@hbrestoration i have a grinder and i bought a capacitor for it because it was missing one but i don't think it's powerful enough. do you know how to calculate how powerful of one you need?
@@Everfalling 20 to 25 microfarad for this one in the video....
Side covers must be produced of metal. In case if stone breaks it can harm you, and that metal plates will save your life. Restoration is done. But for video, not for use.
Yepp, it's better to make it out of metal. I'm using it

Your left side wheel was put on the wrong way, the spin direction is wrong. The cardboard glued to the wheel shows which direction the spin is meant to be. I couldn't see the cardboard on the right wheel. Like car tyres theres a correct rolling direction, on grinding wheels its very important.
Thank you, this is very helpful, I didn't care about that before. When you talk about it, I also think it's really important
Very solid construction of this grinder. Easy to repair. They don't make them like that anymore today. It's a pity that the stone covers are made of fiberglass and resin. They seem not very durable. Generally, very good job.👍
Thank you🥰
restauro eccellente complimenti

Y, cómo le hicieron la litografía de la placa de aluminio de la marca? Interesante.

I just saw a video about this a few weeks ago. (Of course, in a different way.) 😂😁
🥰
SUPER!!!!!!
🥰😍😍
I'm not loaning you MY screwdriver!!!

Restaurado moedor de bancada 😉
Thank youuu🥰
There was no fake ageing on this video. Nice job
🥰🥰🥰 thank youuu
No. Just staged/planted hard filler and some weathering. FGS!
Please don't grind on the side of the wheels, not meant for that. Also, did you do a ring test on those wheels?
I have replaced them
good job!!!!!😊😊😊😊
Thank youu🥰🥰🥰
Quick question: what's the part number of the pipe wrench you're using at 2:01, please?
it is a type of Deep Socket I'm not sure what you want to know?
@@hbrestoration No it's the tool with, thank you for taking the time to reply
Would you restore my Wilton for a video?

How does something 51 years old get a 1/2 inch of crud build up? Was that rust?
It accumulates rust over time during prolonged use

Bros never heard of a ratchet before
So what?
Could be more satisfying for viewers and him to use wrenches. Also you can bang on the end of a wrench all you want, but bang on the end of a ratchet handle enough and teeth in the gears will be broken.
Bro never heard “If you don’t have anything nice to say, don’t say anything” before

I’m like “they don’t sell ratcheting wrenches in Europe???” I’m about to send this dude a cheap little set of gear wrenches or some other off brand.
чистим піском і лак на місці
first again
❤️❤️❤️❤️
Restore that vise ffs
🥰
Waste of time as completely uneconomic.
So...everything not economically viable is a waste of time? Have you ever challenged yourself to do something for the satisfaction and sense of achievement? You might consider attempting a project (but I doubt it).
Well done!
