14.4V Hitachi Cordless Jigsaw Restoration

I found this jig saw from Japan recycle shop. This jigsaw was thrown away for 2 reasons, the battery and the motor engine. The battery is almost dead and the DC motor don't work. In this video, I rebuild the battery with cells and I repaired the DC motor.

I like how older hitachi tools look like some living creatures, like aliens :)

What a great show.

[@jeffersonrooney]

Look, someone from Brazil who lives in the affected areas of Rio Grande do Sul could send/donate some tools that were submerged during the flood for you to recover.

I'm not so sure how long that repaired motor will last... the g-forces on that solder joint when the motor is spinning at high speed would tend to try to rip the joint apart again, and I suspect the soft solder will hold for a while, but will eventually give way under the strain. Expect it to fail again in a few months under normal use. The motors are originally built with the wire wrapped around something to keep it secure (a post or a tag of some kind, often squeezed tight and sometimes then blobbed with solder as well. I've never actually done this particular repair but the engineer in me is screaming at the thing saying "Noooooo its not going to hold for very long!" If anyone has any actual data about how long such a joint holds under reasonable use then please come forward, but at the moment, I am skeptical.

good job. Cordless brush motor tools should come back, they are better in many ways.

Grandpa responds: "Back in my day, we didn’t have fancy recycle shops. We had common sense and took care of our tools. They don’t make things like they used to. I remember when a tool would last you a lifetime. You’d buy a jigsaw, and it’d be there for you through thick and thin, not like this modern junk that falls apart if you look at it wrong. Back in my day, when something broke, you didn’t just toss it. You rolled up your sleeves and fixed it. Tools were made to be repaired, not replaced. You had real craftsmanship, not this cheap plastic nonsense they churn out now. And another thing, back then, you didn't need a degree to understand how your tools worked. You knew how to take them apart and put them back together because they were built with the user in mind. Nowadays, everything’s so complicated with all these electronic parts and special batteries. It's like they're designed to fail just to keep you buying more. I remember fixing my old Black & Decker jigsaw. That thing was a beast! Built like a tank and ran like one too. None of this lightweight, battery-operated stuff. You plugged it in, and it just worked. For decades! If something went wrong, you grabbed a wrench, not a KZbin tutorial. These kids today don’t know the first thing about real tools. They just buy new ones whenever something goes wrong. It’s a throwaway culture, and it drives me nuts. Nobody has any pride in their work anymore. Everything’s disposable, including people’s skills. In conclusion, good job, Gear Show, for trying to keep the old ways alive. Maybe there's a sliver of hope for this generation, but they’ve got a long way to go before they understand what real quality is. Back in my day, we didn’t just use tools, we respected them. And they respected us back."
