Electric Grinder Restoration | Hitachi Bench Grinder

Hitachi Koki, I worked there 30 years ago. Thanks for your restoration.

God bless the people that appreciate old tools and keep Hitachi and Makita running in Japan. Those brands are extremely popular there. People need to look at tool restoration like this. "The tool served you a long and hard life and paid for itself 100 times over. Show some appreciation to what little good craftsmanship we have left, return the favor to the tool. Give it a rebuild."

[@roberternest7289]

You are like Hand tool rescue. No obnoxious music. No grinding through the metal.

[@larrydaniels6532]

Friend of the Earth, saving another quality tool that others would scrap or add to a landfill.Great fulfillment in hearing the grinder purr like a well-fed kitten! Only a true craftsman straightens a shaft with one perfectly placed hammer blow!

[@andrecosta4537]

Machines like these one were made to resist 2 or 3 lives and, with restorations like yours, things will work for more 30 years. Congrats from Brazil.

Worth the effort, as older tools and machinery were built to last by craftspeople. If quality like this is or was available today, you'd be paying a premium to purchase it.

First one showed missing parts. Second one was complete. It's a working bench grinder kzbin.infoUgkxxC8HPnl24fu0XhMU_nbmWNEUoK1RMHXk . One thing I like alot is that it's surprisingly quiet. I don't feel like I'm sacrificing any rpms or power for the quietness either. All in all it's a very nice machine. No vibration whatsoever.

[@Lyndalewinder]

Good to see a complicated restoration without use of lathes, milling machines, parts washers, spray booths and the like - just good old craftsmanship!

[@gear_show]

Thank you so much, I'm happy to hear that :)

well... nice job on the painting.

Great work and respect for all the love and enthusiasm you put into it. The only thing that's missing are the subtitles explaining tools and stuff you're using. Especially the at the point where you put the rusty parts into a i-don't-know-what liquid and add some volts to it I'd like to understand better what's happening...

[@gear_show]

Okay, thank you so much.

[@michaelthibault7930]

The process is called electrolysis. The liquid is water. The powder -- in this case -- is sodium bicarbonate, _aka_ baking soda. The recommended powder is, in fact sodium carbonate, _aka_ washing powder. There's a brand of washing powder, Nellie's, that consists largely of sodium carbonate. If it's to be found at all, it will likely be found near other 'mainstream' detergents, or in the vicinity of 100 Mules Borax -- which is not always in the same aisle. Nellie's is 'boutiquey', so not commonly stocked.

[@bgdavenport]

If you are going to do more restos, a small investment in media blasting and powder coating will save you lots of time and result in a more durable coating job. In addition, you can use powder coat primer to fill the pitting.

Great job, very thorough. I did like it when you checked the runout on the shaft, then delicately adjusted it with one thump of the hammer :)

[@kevinnathanson6876]

Looks very nice; good job! Two safety suggestions for others who may take on this kind of task. First, always short out the capacitor on a motor like this before touching it with skin, to avoid electrocution. You can arc across the two poles with an insulated screwdriver to do this. Capacitors can hold significant amperage for a LONG time even when unplugged, so this is just a good safety procedure when working on any electric motor. Second, be very careful striking a grinding stone, even lightly. They are not designed to absorb blows, and they can microfracture, and then fly apart at 3500 RPM, which is a very unpleasant experience, even IF you are wearing all the correct protective gear and shields. Your next two restorations should be a hydraulic press and a blast cabinet; then you will be all set for many more of these. Keep up the good work!

[@corsair4u2]
