Upgrade Vintage Drill Driver 7.2V to 18V

This is a vintage drill driver 7.2V, National Japan. I failed to convert Nicd battery to lithium-ion because the BMS could not provide enough current for the motor, you can check it again kzbin.info/www/bejne/b3imq2uujddmfa8. I want to get it back by upgrading it from 7.2V to 18V. There are two main parts in this process. The first is rewinding the DC motor from 7.2V to 18V, and the second is the battery adapter.
- DC motor information
Original winding: copper wire 0.85 mm and 8 turns for 7.2V
My first test: copper wire 0.75 mm and 16 turns (failed)
My second test: copper wire 0.60 mm and 25 turns (failed)
My 3rd test: copper wire 0.50 mm and 25 turns (Okay)
I think the armature needs a fan to cool while the current is running.
I hope you find this video useful and enjoy it!
Furthermore, I am happy to receive feedback, suggestions to improve myself.
!!! I'm sorry for the mistake if I did in this video !!!
Thank you very much for choosing to watch my video!
Have a nice day

That one engine was a stubborn one. Rewinding over and over must've taken some time. Cheers for not giving up, this driver/drill looks amazing - like some star trek future stuff. Great work!

Great modification, my friend.. and thank you for your patience in winding the engine for the third time without getting bored. Stay well 👌💪😊

[@adil_daoudson]

This video is inspiring cause he is sharing with us the failures…. Which is more educational than first time right and glossy easy video

[@QuockhanhPham20]

If you can make a small fan at the original battery holder to cooler the motor that will be much better for long time

[@gear_show]

Yes, you're right, thank you!

[@QuockhanhPham20]

@@gear_show Today i had seen again the video you restored this drill and i think i have the right answer The output you made in old video was thoughout the BMS maximum current of the BMS was only 20A but the starter current need more than so if the drill is original you can try to solder the wire output not thoughout the BMS i think it will be worked

Great job! Have to wonder if those mosfets will hang on over time with the increased voltage.

[@Billy_Herrington1989]

Здравствуйте, Ваши видео лучшее, что я видел за последнее время

[@DaftOldMan]

I think it best to keep original motor and convert to 2s Li-Ion (8.4v). Will the trigger switch be ok for 18v. Usually a 7.2v drill will only have a 12v rated trigger switch.

🇵🇱 uparty sprzęcik, ale Ty okazałeś się bardziej uparty. Brawo Ty 😎

[@patrickmorrissey2271]

Great Job! I wondered how you might deal with the battery, since it never was on the bottom of the grip.... I like the support bracket. Kind of looks like a handgun from a videogame called Borderlands 2...... Obviously there is great benefit to using the same Makita 18v battery packs you have all over your shop... But for a little drill like this, it might have been simpler just to put 2 18650 cells together, make a new 7.2 volt (ish) pack, and run it that way???? You could have done that, you clearly have the expertise.... Just wondering. Either way, great job Sir.

[@pmichelazzo]

Great stuff, maby use that old battery compartment to use an extraction fan to cool it off. 🤣🤣

[@sidewinderam9m]

Isn't nail lacquer made of nitrocellulose? Basically the stuff gun powder is made of?

[@mecca8270]

I have an old Snap-on drill that I love but is the old NIC battery and brush motor is there anyway to send over to you to modify the battery packs and convert to brushless motor?

[@aserta]

When tools looked like tools, not toys. I miss these.

[@gear_show]

Yes, it does.

[@TopCat2021]

Good job! it may have taken several tries but all in all good job on the drill and the motor, the old battery case would make a great bit storage container.

[@gear_show]

yes your idea is great, thanks!

[@dennisshepard4928]

Like watching your videos like the recycling of broken worn out things into useful again your knowledge and skills are. high I have learned a lot watching you keep it up 🙂

[@Tosnowood]

Пропало все обаяние олдскульной дрели. У нее был особенный необычный дизайн, а теперь этот громоздкий тяжелый аккумулятор внизу добавили. Я бы на вашем месте просто заменил элементы питания в оригинальной батарее на литиевые, установил плату зарядки и штырьковый штекер для блока питания. Кстати, двигатель после перемотки у вас получился несбалансирован, и его сильно бьет, это заметно даже на видео.

[@gear_show]

Благодарим вас за отзыв!

[@electronixTech]

That drill reminds me of a Lazer gun from a 60's science fiction movie.

[@gear_show]

I think that time they like this design.

[@electronixTech]

@@gear_show I agree 👍.

[@JaviersDIY]

Very impressive

[@jenntek.101]

I love the armature rebuild; Question; The magnets for the 7.x volt are likely stronger and the new voltage would need weaker magnets? I guess; I would need to know the ohms of the original armature vs the newly rewired one. Magnets do matter. The push/pull strength? i.e. ebb/flow ? Anyhow. I love your channel; you've inspired me to rebuild several battery packs to bring old tools new life!

[@gear_show]

I think the voltage depends on the armature coil, not the permanent magnet. I'm glad that you find something from this channel.

[@hugobose2254]

Hi, I have a question. Just like in this video, I got 18v by connecting 5 batteries in series, but I don't know how to charge this battery with a charger. 18v - 18,5v - 21v which one should I use?

Try cleaning the armature of the dynamo, usually a lot of charcoal powder gets stuck between the coppers

[@Yorumcu63]

Another great video. I think with 0,5 mm dia copper not enought for long time life.As you know 1 mm2 dia copper can carry 8 ampere (D.C) So 4x18=72 WattI don't know just watt to tork value calcuations but I know this fan colling to armature very important for efficieny and long motor life .you can use maybe you can add a current limiter circuit to old battery section .If you want you have great patience .Actualy this is show me patience must be for good referbushing Meanwhile you can make a slot for bits to add metal section (to trigger's cross area plastic drill holders or magnets) Great video Congrulations

How to calculate wire size and turns?

[@VictorGallagherCarvings]

Where can I get a pulley puller like that ?

[@Hoellewood_Solutions]

I’ve got a question for anyone who is interested. I’ve got a 115v compressor that I’m interested in modifying to run on 2 18v batteries. What would I have to do to the motor to make this possible. The only available motor info I have is Horsepower: 1.5 Volts : 115 Hertz : 60 RPM : 3400 I run a lot of job sites totally cordless until I can’t anymore. I don’t know if any cordless compressors, other than the m18 that could possibly run what I need. Like my concrete T nailer or framing nailer (I’ve got a cordless framer, but still want the power to run another). Would I be better off biting the painful bullet of the m18’s cost ($500+) or to create a cordless conversation monster? I do understand that the compressor would be a little less powerful, but that’s a trade off for convenience. I just don’t want to run my gas powered due to the Biden prices.

[@sakibsarwat5064]

i thought you would somehow put a cooling fan in the area of old battery but anyway that small motor may not need a fan
