Angle Grinder Hack! Don't Throw Away the old Angle Grinder!

I installed a 220 volt blender motor on the broken grinding machine.
It's not as strong and fast as it used to be, but it can be used in small jobs.

Yeah! No. Got it, only the foolish mock the reaper. I felt my IQ drop watching this.

Я один вижу. что отверстие просверлено не по центру? И что ножовой можно распилить болт быстрее?

[MichaelWTurner]

My first thought was, why the hell would I do that when I could get one for less than 20 bucks. Then I thought to myself, I just sat here and watched this whole video and it has 2.2 million views. Well played sir...well played.

С такими оборотами пластилин только пилить, да и ножовкой быстрее будет, чем на видео шпильку грыз этой "болгаркой"

WHAT was the point in that? Was the original armature screwed? The replacement motor is WAY underpowered for the job though! An angle grinder should run from around 10000 to 16000 rpm. That motor sounded like it was barely making 3000! BAD move!

So even though it can be used again it has a much smaller motor now with a real chance of catching fire, well done.

For someone who fix something that was broken, with stuff you had laying around, I think you did a fantastic job. For something that was broken, and now works, I think you hit the nail on the head.And if you need to upgrade it, I’m sure you will. Keep up the good work.

You've not only wasted your own time sir you've also managed to waste all of our time as well.

This should be titled 'Take a weekend off and build an angle grinder'.

The effort...is more expensive than the result....good try

LOVE THE GUARD on YOUR GRINDER BRILLIANT !!!

[prithvirajkanne]

Very good experiment. You succeeded. All the best. Keep doing more. This tool will be very useful in emergency situations. It's better to use it like this than throwing it in trash can. Spending money in replacing the internal parts like motor is very expensive. It's a good try. You have succeeded. Don't listen to the looser's words, they don't know what to do, how to do. Even if they know rocket science, they will simply eat and comment others. Don't listen to them. Do whatever you like. You are born to live your life.

There IS a reason a side grinder, 4" or 9" version, has a small pinion gear driving a large ring gear. The reason is the necessarily small motor, (especially in a 4" grinder, which most people think are a direct replacement for 9" grinder. They are NOT.), needs to gain some RPMs, so it will have some torque. The gear ratio enhances torque, as well.

If the manufacturers could get away with direct driving them, they would, since it would be so much cheaper.

You have resurrected a good little Bosch side grinder as an underpowered shadow of it's former self.

I did come up with a much better use for part of the side grinder, though. The part was the output shaft of a 4" side grinder I killed a few years ago. I don't know the brand of the shit-brown grinder, I found it in the trunk of a car at the wrecking yard, and they gave it to me when I paid for my car parts. It lasted almost a year, but it didn't have a spanner nut like most grinders, it had a large cup washer, and nut; like a bench grinder would.

A few months ago, I bought one of those cubic manmade superstone grinding wheels, (hard enough to grind carbide), from China via eBay. The problem was, I needed an arbor for it.

I planned turning one from round stock, but looking in my 'inventory' for a nut and washers to use, I ran across a couple of output shafts from dead side grinders.

Because of the nut and washers, I first thought it WAS part of a bench grinder, then I recalled tearing apart a couple of 4" grinders I had smoked one day, because I wasn't up for wrestling with my 9" side grinder, but there was stone needing to be polished. I got it done, but I was down to my last 4" grinder, (and I've been hesitant to get it out, since!), though do still have the 4" air side grinder.

After checking then for runout, I ended up using the side grinder output shaft as the basis for an arbor. They are good, tough alloy, but still machine easily. I turned the gear end of the shaft down to ½", then turned a bushing for the ⅝" shaft and 20mm grinding wheel.

In the end, it was a much easier project to use the output shaft, than to re-invent the wheel, making one from scratch.

12volt dc motor 775 is designed for light duty application such as act as part of component of any machinery. this motor itself will fail to carry peak load in compliance with factory specification not only that but also motor seems to be loosing its life very soon if engaged to such heavy duty application.

That was a very clever troll video. I realised what you were making after just a couple of minutes, yet you kept me watching until the end because *surely* there would be more at the end.

[andrewsavage]

go to harbor freight with a coupon and spend $10 on a new one? That is a lot of effort for a junk tool in the end.

This video is a representation of your life.

Мне интересно, как ты нашёл центр на отпиленном валу редуктора?

[donalddarnell]

If he had a grinder he wouldn't have needed a hach saw for that. Lol.

What did I learn... 1- dude does NOT own a decent phillips screwdriver (strips every screw) 2- thinks throwing new grease over old dried out contaminated grease is a good idea (lazy), 3- hacksaw blade has a hard time cutting plastic (lmfao), 4- apparently only has 2 sizes drill bits (hole is way to big for new shaft, 5- off center hole for new motor shaft, will make for a great vibrator, not much else (again lmfao). 6- 120v printed circuit board (bridge rectifier) hanging loose off of cord!!!(what could possibly go wrong, see it contacting steel vise?) You would think with 3/4 of a million views (why, just why) this guy could afford a decent screwdriver, and drill bits/tools!
