    No, but I can see it from here.

    [when at about flight level 45, of course :D]

    I realized maybe I hadn't run the lathe in my vids long enough to get to hear it very well and to get a better idea why I don't want to work on it.

    So I shot this vid.

    I meant to record longer, but it was giving me a headache.

    The lathe was cold, but notice how after it ran a bit it actually got more rattly which you can hear after I slow it down and then speed it up. Compare 800 rpms the first and second time, for example.

    http://www.youtube.com/watch?v=Dqb2KPsNoIY

    I had someone stop by recently to consider buying the lathe (figured I was in the mood to give a great deal), but once he heard it for a while he decided he did not want to take on the project..

    btw, with a mech stethoscope I can hear what sounds like a bearing rattle at all rpms on the newer spindles. Gets louder at higher rpms, although interesting after running at higher rpms even a minute the rattle is louder at slower rpms than before run. Only objectionable above 1800 rpm, and then takes off like a jet engine. With the stethoscope absolutely no rattle sound at any rpms with my older 2436.

    Bill,

    You got a lamer and Oneway can't or won't fix it. If they won't take it back for a refund and you don't want to sue them, take some nice pictures, put it on e-bay, and move on. There are companies in your price range that will actually appreciate your business.

    Bill, You need to sell it to somebody who has only turned on a Delta 1440 Lathe (Reeves Drive) or any other comparable Reeves drive lathe. They will feel right at home with the sound.

    Bill, I have been reading this from the beginning with great interest. I own an old 2436 which is one of the quiet ones! However, what if I need to change bearings or spindle etc. OW is not making them like they used to and so no replacement would be available. What now, 1 - rebuild the spindle and replace bearings yourself? 2 - Try to get the old parts from OW? 3 - Sell the 2436 and move on? Very interesting set of circumstances you have presented us with. What a bummer! I hope OW comes through for you. I could not stand that noise and I am totally deaf in the right ear. Thanks for posting and keep us informed.

    I'm worried for my OW too!!!

    I am very grateful to have read and learned about this critical issue. I also now live in fear of having my old quiet OW lathe needing new bearings or spindle. It surely is critical for OW too, as I see a very serious growing problem for their business. Has it reached the stage where concerted effort or appeal by the community is needed to get OW to recognize a solution is necessary? Are all new OW lathes noisy? I'm worried.

    Bill I for one want to thank you for posting about the problem....I do not under stand why any one would be upset with you for posting about a problem such as the one you are having...........no mater what company it is I would think they would be the FIRST to want to get the problem solved....quickly and to the customers full satisfaction.....having worked in customer service of heavy equipment my first instruction from higher ups was if I couldnt fix it to the customers COMPLETE satisfaction....exchange or buy it back!!!and bring it in...Do it quick...do it corectly and above all leave a satisfied customer......any thing else will cost ya dearly.....in lost customers!!! just my thoughts....

    Bill, I think the key question you keep asking in this discussion is "do all new 2436s make this noise"?

    Certainly, it would be interesting to hear from other new 2436 lathe owners on that.

    But I more interested to hear how OW has answered that question for you.

    I can see one of two responses from them:

    1. Your machine is unique - none of the other 2436s we have manufactured experience this noise.

    2. All new 2436s make that noise at that RPM to some extent but we think it is within acceptable tolerances


    Other than sending you new parts, can you convey what OW's general position is on this issue?

    Bill, No turners and for sure no oneway owners are upset with you. You are bringing up what to me is an important issue regarding noise levels. I think you will get it resolved one way or another in St. Paul. I have worked on my 2436 for the last 12 years or so. But if the new machines are loud it then becomes a factor to a person thinking of buying a top end lathe. I would not want to live with that whine. Just my 2c.

    Bill, I have watched and heard the videos. I am no machinist and guys like you have forgotten more about turning than I will ever know. I am GLAD this issue has been brought to light and nobody has any good reason to be upset with you for it.

    You are a more patient man than I am. I would have scrapped/returned/sold this lemon long ago. You've been working at this since December?!?!? That would be enough to make me go back to flat work!

    Good luck and enjoy shopping in St. Paul.

    Almost sounds like a reversed high speed quick stop return delivery is in order.

    Just make sure you tail gate is down when you slam on the brakes.

    Bill, it is obvious what is going on. Oneway at some point in time made a change to the assembly to save themselves some money. They are being super nice to you and at the same time noncommittal as they do not want to have to replace a zillion headstocks out there. A well designed piece of machinery does not sound as if it were in pain. They know exactly what the problem is but do not want to deal with it. What they do not realize yet is they will deal with it sooner or later. No one wants to turn on a thrashing machine. Life is too short.
    There are other great options and companies out there that would love to have their equipment in your barn.

    Jerry

    Peter and Bill, The bearings have numbers on them and you just order those bearings and no problem. You can put them in yourself. I hope he gets this settled in St Paul.

    Wouldn't they have to be pressed on to some extent, precisely? I haven't taken mine apart to look.

    Bill, I totally agree with Jerry here. OW will have to deal with this "One Way" or another. If they want to remain a leader in this field of turning equipment, it would behoove them to address the problem directly and get it behind them. Just my opinion. BTW Bill, Jerry, John King and I all have One Way 2436 lathes and we are watching and listening.:(

    Steve, no. You have a large shaft. The bearing starts on that shaft and gets pushed to position. If tight, I start with a piece of wood and tap the bearing to start on the shaft. If still tight then a hollow bar sits on the bearing housing and you tap the bar till the bearing is where you want it to be. You dont want to bang the outside of the bearing above the race and you dont want to whack with a piece of metal so hard as to change any diameter. In most cases you just clean and oil the shaft and start the bearing and with a bit of effort it slides. You do not want to scratch the shaft either. You could also use wood instead of metal to slowly get a tight bearing in place. I have also used two pieces of wood to protect the bearing and on my wood vise tapped the shaft down onto the bearing. Not rocket science. But things need to be clean. One tiny bit of crud makes things a bit harder. Common sense and its prettty straight forward.
