content: I think this pump I am working on qualifies. I had to put it away so I can relax for a while by the time I got to the dead insect in the rust covered pump head mechanical area.It's in such a place that I can spot it through a hole but you need to yank on plastic shit to get this cover off and I know its going to freaking fly out when I do it. I might cut a hole in the side just so I can remove it gracefully and patch it back upI swear pumps are disgusting. I think it died on top of a fucking shaft screw too.I feel so fucking unclean now even with the pump outside. I don't even want to throw it out. It needs to be disposed of in a fusion reactor like Alien 3. I was spinning this shaft around looking for set screws and boom some dead fucker is stuck to it. God damnit fucking mechanical engineers cant put a mother fucking mesh

content: Just bought 2 wheels for my sack truck today (old tyres had perished). When I put them on, they wouldn't go round. The plastic hubs had flats bulges so the roller bearings wouldn't go round. I wrecked my back getting the wheels back off, and spent 2 hours dremmeling the flats of the hubs. Horrid.

content: time to upgrade to a mean die grinder 1/4 inch shaft instead of a dremel. It sounds like the wrong tool to use as something as big as a truck wheel.oh a sack track is a hand cart. In that case its still borderline IMO.

content: might be interested in tools like this if you got a job too big for a dremel but not worthwhile for a die grinder investment (don't have one myself yet), but I do have thesehttps://www.grainger.com/product/2D916?gclid=CjwKCAiAwojkBRBbEiwAeRcJZCXsWrsIKGGvg1tE7s7BZqZQ5dBfszuPUXvCLwR7160VQ6HV6GD8_RoC1QIQAvD_BwE&cm_mmc=PPC:+Google+PLA&ef_id=CjwKCAiAwojkBRBbEiwAeRcJZCXsWrsIKGGvg1tE7s7BZqZQ5dBfszuPUXvCLwR7160VQ6HV6GD8_RoC1QIQAvD_BwE:G:s&s_kwcid=AL!2966!3!50916684477!!!s!58504367061!I also found if you don't care about surface finish, the braided thick angle grinder wheels actually eat plastic with prejudice. You need to sand it afterwards though.https://www.zoro.com/weiler-twist-wire-wheel-brush-arbor-4-in-94102/i/G0866162/feature-product?gclid=CjwKCAiAwojkBRBbEiwAeRcJZOVgQVFHaVuKpAsw8iQJUqUlDB-9vbDDYK4KP66s3_aBzcwQgbfYJBoCU4IQAvD_BwEFor hand truck/sack truck wheels (fully hard rubber) I found that actually letting them rotate freely against a angle grinder with the braided white brush actually cleans them (and they spark a bit too despite being hard rubber).i got a hand cart too, I was going to replace the wheel but you need a special size bearing puller to remove the wheel from the shaft.

content: alternative is to beat it in with a sledge hammer and tape the wheel back togetheran option for my hand truck lol using some leftover jb weld (hardening as we speak) and stints would be cheaper then buying a damn bearing puller

content: Quote from: coppercone2 on March 08, 2019, 08:03:40 pmFor one off jobs like this it may be possible to rent one from the nearest tool/hardware store. Many places offer this service. A lot easier (and probably cheaper) than trying to use Dremel for something like this.

content: they will rent a anemic bearing puller? it would need 3 jaws like 3mm widethe wheels have little indents for them and they are aluminum hubs.i suppose i can take a flat bar and drill a hole in it and cut it in half and weld it together behind the wheel so the big bearing puller can be used. or just use a thick flat bar with a flame cut notch in it so it can fit over the wheel and be stiff enough. They fit a bearing inside of the wheel and they require you to pull the entire wheel off so you can bang out the bearing. I kinda have a feeling that the bearing puller will rip out of the aluminum rather then remove the wheel given how fused it looks like it is, so I think I will be forced to go that route or to cut the wheel in half with a sawzall or somethingit's built like a complete bastard when I was painting it I had to regrind all their welds (looked like wounds on the top).i feel like a complete boss though now that I figured out ball bearings are a standard part like resistors. I thought everyone was pretty much custom designed.

content: I assumed you were referring to the die grinder (or the weird die grinder like stone that attaches to an angle grinder) rather than the bearing puller. Confusing, lol.FWIW, a die grinder spins at >2.5x the speed of an angle grinder. This can make a difference as to what you can do with it and the results you can get, along with all the smaller bits you can use it in. (Particularly if using it as a redneck turning tool). Pneumatic die grinders are dirty cheap. But if you want a cheap electric die grinder on a budget, your options are less attractive.I've the cheap electric die grinder that looks like the generic version of the entry level 1/4 HP Makita. The one that looks exactly like a blue bottle with a black neck. It is a bit underpowered and the motor is unbalanced. The bit spins true in the collet, but the entire neck of the grinder vibrates due to the motor, so it is highly suboptimal with most bits other than cutoff discs. I find a cheap trim router works much better and has plenty of power. A generic (HF or the like) hand/trim router costs about the same as this cheapo die grinder, it has the same collet size (can be had in 1/4" or 6mm), it takes the same bits, and it spins at exactly the same RPM as a die grinder (~ 27-28K rpm). But this cheapo trim router has power for days and the motor is very smooth and balanced. It just doesn't have the reach of the traditionally shaped slender-necked die grinder. So if you want a perfect stubby electric die grinder, you might want to give it a try. Works so well as a "giant dremel" that I have two of them, one setup with a steel guard for cutoff discs, and one for the other bits. I got the one in 6mm, so I can use cheap import carbide burrs and hard points. I don't think they're much good as trim routers, though, due to the shoddy trim router attachments. I would spend more for a trim router.In the US, branded electric die grinders start at over $100.00 for the really weak Makita one, for some reason. The better part of $200 by the time you get into the full-powered ones. Just not that common of a tool, I guess. You can buy top brand angle grinders for peanuts, in comparison.

content: i want the milwakee fuel die grinder but it is only suitable for the stones because you don't have RPM adjustment. It will annihilate brushes and nylonI think at 20,000 RPM it will start to destroy those braided brushes too. Regular brushes are no good on a non adjustable speed grinder unless you wanna feel like your fighting a fucking pissed off porcupine. I imagine at 25k they might just explode.

content: QuoteSeems like most die grinders are not adjustable? Even the expensive ones. Bosch makes one of the only adjustable die grinders that I see for sale, here. But it maxes out at something like 7-8K, so it's a totally different tool from most die grinders.For a corded grinder, you could use a plug in router speed controller. I don't have one, but I find a regular full on/off foot pedal works, somewhat, with my die grinders, just feathering it and using the inertia of the motor to even things out. I have never used a wire brush in a die grinder, though. I didn't even realize that was a common thing... wire brushes with a 1/4" round shank, at any rpm rating.

content: Clockwork mechanism full of not only a mix of alive and dead cochroaches, but also essentially had built up a crunchy lubricant that packed every cavity of it from the bugs that got trapped and pulled in between the gear teeth, This mechanism was about the size of a drink can, was generally heated to 40C in a humid atmosphere,There are smells you cannot un-smell, and this was one of themThe mechanism was bolted together in about 15 layers, so pull it out of the housing, freak out when it starts having small insects come pouring out of the top, then cleaning out the bug goo, unbolt the layer and repeat..I went home early that day, and no one was going to stop me, I was not happy.

content: yea I had a invasion like that once from some unknown source (possibly a air conditioner bought from store).I was hunting cock roaches in my house for 3 days and I deployed8bug bombs to flush em out. Happened right during a remodeling too, after i sealed the sheet rock but did not cut away the expansion foam. So I was pulling dead bugs out from under expansion foam (thank god it fucking solidified before this happened). I just fucking came home from work and there was fucking like roaches all over this room. And there was a hole from the room going into the basement.Thankfully I think the centipedes ate the roaches that I did not kill personally or gas.New rockwool kicks ass, the walls are fucking sealed super tight with no gaps in em.It was fucking ridiculous though. I thought maybe a prank even. Like the fucking Sears was not that dirty (in a nice expensive mall) and I beat all over the air conditioner getting it into the house and even ran it for a while with no problems. It was like a day later. I did leave a window open but there are normally no roaches here. And these roaches were dumb and large like they did not know predator avoidance well... but I can't imagine kids threw pet shop food into my window.
