Noisy T&C grinder head
I have a particular tool and cutter grinder. Its head is noisy, in
fact, its noise resembles the sound of a rotary siren (though not as loud). Would you say that the most likely cause of it is bad bearings? |

Um... why not just use the _almost_new_ Snap-On Mechanic's Stethoscope he bought for $2.00? Seriously... It must've been over 40 years ago that I learned the value of having an _actual_ professional stethoscope with interchangable probe tips in the kit. Especially for machines with big tin bodies around them, they're invaluable for finding where the real noise is coming from. Further, unless you stick it into a running fan, or light it on fire, a good stethoscope is a one-time purchase. There are inexpensive electronic versions with contact microphones, too. I dunno if they'd last forever like mechanical ones do, but if you keep the batteries stored separate from the tool, one should last many decades. Lloyd |

At this point, we're not to the relube point, yet. So, you're changing the question. There are bearings..and then there are high precision bearings. Motor beariings may or may not be medium precison bearings Spindle bearings ARE high precison bearings Yes..Iggy could probably stuff oatmeal in the bearings of either one and make it quiet enough to sell. And when the new owner gets it back to his shop and it starts to squeal within an hour..they are going to pull it down, check the bearings..descover the "oatmeal" used to camoflage the squeal..and be less than comfortable buying the next item Iggy has for sale. Bearings of this nature are cheap enough. Motor bearings can be had for $5 for the pair if you want to run Chinese bearings (I dont..but..they work well enough for motors) However..spindle bearings are High Precision bearings..and they might cost him $50 for the pair. And when he sells it..he tells them he put brand new NSK/SKS etc etc bearings in the spindle and they are very happy with him and they buy other machinery from him with full confidence at his asking price. You dont work in the manufacturing/machinery repair industry...so you really dont have a clue how the thinking works. People who buy used machinery..know full well that they are not buying a brand new machine...but they expect it to do what they are buying it For..and unless they are told up front that bearings are bad...they expect them to be "adequate". Bearings can be a pain in the ass to replace in metalworking machinery. Seriously.... https://picasaweb.google.com/1040422...pressorRebuild This (below) was a simple bearing repair..that required a forklift just to remove the assembly..and the bearings themselves were $600 (5 bearings total) https://picasaweb.google.com/1040422...aTurretRebuild the photos above were just a sampling of the 50 (of each projec)t or more I took while I was disassembling the turret..so I would know how to put each back together again. As you will notice..the crack in the casting was the issue with the turret..but because of the expense of repairing the crack ($1800 for labor)...putting in new bearings was indicated and the client agreed) Now they dont ever have to worry about spending another $1800 just to remove the ******* again when a bearing goes out..and it would have) Its not...always like swapping out wheel bearings on your Chevy Luv......

Has iggy made any effort to spin it and feel for flat or hard spots? Does anyone else besides myself get sick and tired of this cocksucker not providing enough information over and over for years on end leading many of us on wild goose chases.

The focus of this newsgroup has shifted away from learning to be mechanical and learning how to think on your own to who can do the best job of getting on their knees and sucking Wieber's cock. |

typed in rec.crafts.metalworking the following: People who buy used machinery..know full well that they are not buying a brand new machine...but they expect it to do what they are buying it For..and unless they are told up front that bearings are bad...they expect them to be "adequate". Bearings can be a pain in the ass to replace in metalworking machinery. Seriously.... Also, there is the difference between expectations of what constitutes "adequate". Which as I think about it, really means "this machine has 500 hours to go before [e.g., the bearings] go." which, for a production shop running machines 24/7 is less than a month. but for a home shop, that may last ten years - and then the bearing will need replacing because they've been sitting so much B-) -- pyotr filipivich "With Age comes Wisdom.

Regrease them, and see if that helped. I do think the drawings and photos are excellent idea. True indeed.

Shrug...When I fix a clients machine...I avoid putting bandaids on them..I fix them properly so it has a much much longer life span. For a hobby shop..your method will probably be viable. The general rule of thumb, especially for commercial operations, is that as you have it "open" now, might as well replace the 'marginal' bits while you can. I.e., when replacing the throw out bearing on a clutch, it really doesn't make a lot of sense to decide the old clutch has a few thousand more miles on it, and put it back in. You tear a machine apart, you replace bearing/seals putting it back together. Save having to shut down and do this all over again "soon." Of course, some of that is a judgment call.

It has a "spurt" hole when the spindle lines up with a hole in the housing that lets a burst of air out of the bearings. It definitely sounds like a siren, and also uses a lot of air. Jon |

Um... why not just use the _almost_new_ Snap-On Mechanic's Stethoscope he bought for $2.00? Seriously... It must've been over 40 years ago that I learned the value of having an _actual_ professional stethoscope with interchangable probe tips in the kit. Especially for machines with big tin bodies around them, they're invaluable for finding where the real noise is coming from. Further, unless you stick it into a running fan, or light it on fire, a good stethoscope is a one-time purchase. There are inexpensive electronic versions with contact microphones, too. I dunno if they'd last forever like mechanical ones do, but if you keep the batteries stored separate from the tool, one should last many decades. Lloyd Good point. I bought a stethescope a few years ago for just this need..and found out it works very well...but a screw driver works Almost as well and doesnt need any special care in my tool box.
