1$ Vintage Electric Pencil Sharpener Restoration & Update | National KP 150S

This is a vintage electric pencil sharpener, made by National Japan. I bought this device from a Japanese recycle shop for only $ 1. It does not work anymore, but the mechanics inside are still in good condition. I decided to turn it into a rechargeable device. I'm really satisfied with the results I did.

I like these old Japanese gadgets, you can see the craftsmanship in their work even 20 years ago

[@zik316]

Love the different type of restore. And the overkill motor and battery upgrade. Everyone needs a portable electric pencil sharpener. Cheers.

[@mykalimba]

14:05 You have "DRILL" where it should say "DULL".

[@adeebmomen4541]

It said “Dull” not “Drill” Understandable since English is not your first language. Nice upgrade.

[@gear_show]

My bad, I'm sorry about this mistake.

[@clintraley856]

@@gear_show I wouldn't even worry about it. That was a great idea! And the sharp function is really clever. Keeps you from wasting material.

[@troyna77]

It obvi what @gearshow meant. @adeeb momen No need to point out things like this. You commenting on an obvious language translation error is gratuously petty.

[@adeebmomen4541]

@@troyna77 it’s not really a translation error when it literally said “dull” on the original sticker. I’m just pointing out that dull and drill have different meanings. And because he went the extra effort to print a brand new sticker in the first place!

[@aquad7249]

@@troyna77 Actually I think it's a positive thing to comment, especially the way he did. He learned a new word or atleast got a better understanding that way.

[@gayle525]

That’s the best sharpener I have ever seen. Most leave little pieces of wood on the pencil somewhere. And I thought you would have to sharpen that roller. Sweet job. Also the conversion was the best.

[@Heymrk]

You should not sharpen pencils and color pencils with the same sharpener. Colored pencils are made of wax and pencils are made of graphite. Using both in the same sharpener is bad for the mechanism.

[@somanyfnbananas2774]

That was my first thought when I saw that

[@timehunter9467]

It doesn’t look like the motor will draw too much current, I can’t see it needing to work hard just sharpening pencils.

[@PureRushXevus]

12:50 think you mean "dull", which is the opposite of sharp, not "drill" :) I don't think there are pencil sharpeners made with a setting to just eat up the entire thing, it's probably to get a thicker end point on the pencil, for thicker lines (oh no I just realised you made a label for it too xD)

Has this thing burst into flames yet? Just wondering because it is only a matter of time before you get enough graphite dust all over that exposed battery pack to cause a short circuit. Congratulations on the "how to make a homemade fire bomb" video.

Видео-пример как делать нельзя), почему не проверил двигатель сразу после разборки? Просто мог быть заклинивший механизм, да и отремонтировать этот двигатель можно, а то перекромсали внутри всё, разве это реставрация? Зачем аккумуляторы пихать в такие приборы, карандаши каждый день точить пачками будете в поле? Про кнопку уже написали другие.

[@backyardsounds]

Excellent upgrade and restoration!

[@MrZergeus]

Микровыключатель не выдержит таких токов. Надо было подумать еще

[@brainuser312]

It should be called 'Sharpener cleaning', as in fact you did NO restoration at all. You didn't even remove scratches from the body, to say nothing of blade sharpening. And the most strange thing is that you show the worn, full of scratches body close up in the end! Bad job. Imho.

[@sebastiannielsen]

I dont think that little button is gonna take it enough for it to have a useful life. Motor is propably sucking a lot of amps through that poor little button. There are microswitches that can fit the box but which can swallow atleast 1A. Otherwise there is small relays (that can fit somewhere else in box where there is space) that you could wire along with the button. Dont forget the flyback diode then, so the back-EMF don't eat up that little poor button.

[@enriqueromero7226]

The lopsided outrigger unpredictably precede because fireplace gully preserve modulo a fantastic employer. materialistic, narrow bra

[@TempleRWR]

There is one unpleasant moment. The tact button is not designed for such a current consumption; it can quickly burn out. You shouldn't have put a limit switch, they are designed for high currents.

[@sharkymax]

OMG! The company "National" has been bought out years ago. Truely vintage.

[@markfriesen1435]

National wasn’t bought out. It was always the original name of the company and was used as the home brand, but as the international export brand name Panasonic became world recognized, the home brand National was retired to consolidate recognition. I still occasionally see an old National sign here and there around Tokyo

[@MuhammadDaudkhanTV100]
