A local fabrication shop gave me a literal trunk-full of broken tools. In the pile were these 8 Makita 9005B angle grinders. Some of the issues are obvious but I'll be troubleshooting and testing to determine why they all failed. See links below for the parts and tools I used:

@@marconiandcheese7258 I don't really feel like I have enough experience to give you a thorough list. I can say that store brands like Kobalt, from my experience, don't seem to have any replacement parts available. Is pretty safe to assume the same for any cheaper brands as well. Major brands like Dewalt, Milwaukee, Makita, Bosch, Hitachi, Metabo, and Porter Cable seem to have really good replacement part availability. So far, I only have experience with corded tools but my next project is going to be cordless Makita drills, so we'll see how that goes. I'm happy to hear my videos are giving you the confidence to repair your tools. I'm no pro so if I can do it, so can you.

@@marconiandcheese7258 Dean Dohorty on youtube has a repair video channel and is often pretty vocal about his opinion on various tools. I'd recommend having a look there. From memory particularly new Milwaukee tools only have parts sold as segments of the tool making repairs economically unviable (meaning you don't buy a controller, but the controller, wiring and trigger assembly in 1 pre-made package with the price to match), doesn't mean you can't fix it, but does impact if it's worth doing so. Bosch (Professional) and Makita are often praised by him.

This stuff is like lawnmowers. If you're running a business it's much cheaper to simply replace broken tools than try to fix them. However, for the person with time you can bring "trash" back to life. Makes me sick to think how much of this stuff is simply thrown in a dumpster. Computers too.

Repair cafes are good for this, and are growing fast around the world. They thrive on people like Mike who have some fettling expertise. A lot of repairs are at the 'new brushes/replace the cable' level and can be done very quickly/easily. Given a few people who between them can do a bit of electrics, sewing, woodwork and soldering, a lot of stuff that would otherwise be thrown out can be fixed.

Yeah, I've tried repairing cheaper tools but they don't make it easy. Between not being able to get replacement parts and making them overly difficult to repair (like you mentioned), you might as well just buy a new one (which is what they want).

@gutsngorrrr Месяц назад

Great repair job, done a few of these myself, they are great angle grinders. I would advise, when doing all that work in the repairs, change the bearings rather than servicing them, as there will be damage if they're dry.

The 5 in 9005 model I believe classifies it as a 5" model. I used this model in the 90's for like 8 years. Only issues I ran into is breaks in the cord in the strain relief area and of course, worn out brushes. We used to use 7" stones on it but had to be careful not to overheat it. I bet the failed stator ones were due to overloading for too long a stretch. You know it's overheated when you can barely hold your hand on the outside of the stator housing!

Used the female outlets left over to make pig tails . The Makita 9005b was a real work horse . I used them for decades. And they were worked hard . Brushes and cords were the main fix . Would go down to the makita store to get parts once a year and spent a week end getting them all up to snuff . Even made my own guards for 7" discs were as good as factory .

Great work in repairing the grinders , while ordering the replacement parts , you should have gotten 8 disc guards for them .

@Mikeattempts Месяц назад

Why? So the next person can throw it in the trash where it belongs along with that stupid handle that comes with a new grinder.

@Mikeattempts Месяц назад

@@Trump985 Yeah, that's what I was thinking too. A guard is good for a homeowner who has never used an angle grinder but I would venture to say that the majority of pros don't use it. Personally, I do find the side handle very useful for better control.

@georgeforeman89 Месяц назад

@@Trump985guards are trash. Handles, however, I find much more useful. Not all the time, but those big grinders are heavy and I find I can get much finer control using a handle. They’re handy to have once in a while anyways

@Trump985 Месяц назад

The handles are certainly useful on the bigger grinders I have a 12in angle grinder and that has the handle, but on these little 4.5 and 6in grinders they are absolutely pointless.

I had to replace the stator on my Makita circular saw and the arrangement was identical to what you show in your video. Before fitting the stator into the plastic housing I cut 2 pieces of 20mm diameter plastic conduit to approximately 20mm long then cut down the length of the conduit to one side only so that I could squeeze it to reduce the diameter to allow me to fit inside of each spring, I then lowered the stator into the plastic housing with the conduit still inside the springs, then offered the plastic conduit on to the brush holder using circlip pliers, I opened up the pliers and pushed the spring over the brush holder

I gotta say that this was a good lesson for me on testing armatures for continuity as I'd been doing the bar to bar test on the commutator completely wrong. I've been informed that the way I was attempting it is more commonly called a "pub crawl". Who knew?

@Mikeattempts 27 дней назад

This was my first time testing electric motors so there might be other tests that I didn't perform. The bar-to-bar & 180-degree tests were Ohm measurements. The continuity test on the armatures were to make sure there wasn't a short between the commutator bars and the shaft or the bars and the steel stack. Anyway, I learned a lot off camera while trying to figure things out. :)

The 9005B can take a beating! I have burned up, smashed and worn out many of them. Not abused mind you just worked the hell out of them for several years and they wear out of something failed . I have largely moved to cordless Milwaukee grinders now as my grinding needs are minimal and I have grown to hate a power tool with a tail! . However when I have a lot of grinding, the old 9005B with a tail comes out and away we grind. Bad power cords and worn brushed were the biggest cause of stoppage I had. I kept a spare cord or two and brushes in my truck as a result. Good stuff

Yeah, besides chainsaws, grinders are probably one of the most potentially dangerous tools you can buy. It doesn't help that some people purposely use them incorrectly. I looked into getting replacement guards but they're not toolless, like newer grinders, so I assumed they'd just end up in the trash anyway if I sell any.

Beautiful. I've actually serviced a few at work as a maintenance electrician for a facility with a full service auto/machine shop and just threw out any that had stator issues.

I love fixing stuff. It's so satisfying. I buy retail returns and fix them for fun. Some items actually have nothing wrong with them. I think some places allow no-fault returns. Or the customer has changed their mind and made up a BS reason to return the thing. Some items are actually brand new - with just a damaged box or something. I got my 3D printer from a pallet of returns and it was brand new in an unopened box. The note on the box said it had been returned because they shipped him the wrong printer.

@Mikeattempts 28 дней назад

That's awesome, where do you buy retail returns? I bought my first 3D printer a little over a year ago and it's a lot of fun. I even did a video building an enclosure for it. Designing parts takes me forever though so I don't get to use it as much as I'd like.

Awesome work Mike. An alternative approach (and no approach is better or worse) is to determine the weak link in the grinder i.e. the stator . In the 1980's I was running a fab shop and the go to grinder was Bosch and the weak point was the armature. So in this case repair four grinders and keep spare bits to keep them running. Absolute luxury in a shop would be three grinders with a cutting disc a grinding disc and a cup brush on each and a spare grinder on the shelf. Please never use a grinder without a guard. Look at How to shred 4 fingers with a woodworking power carving disc - stumpy nubs on you tube.

@Mikeattempts Месяц назад

@TehButterflyEffect Месяц назад

I have a couple of Bosch grinders. I used to use them almost exclusively because they are really smooth and vibration-free. However, they have really thick casings which leads to uncomfortable hand cramps after using them for hours. I went to the newer US-made (they don't make them here anymore unfortunately) DeWalt 11amp grinders, which are more powerful and much more comfortable for medium-sized hands.
