    Straight oil of any common type will not cool nearly as effectively as a water/coolant mix. The lubricity may go up, but the cooling will go down. Its difficult to quantify exactly because with added...

    Late to this thread, but early this year I built a heavy duty roller for work. All three rolls are powered by hydraulic motors, the shafts are 1.375 4340 at the bearings, reduced to 1.250 where the...

    That is a great chart. And looking it over I take back what I said in post #5. It might not be bad at all. Sharp cutter and coolant may be quite workable.

    Ken, that was my first thought too, but the OP only mentions cross-slide feed. If the long-feed doesn't slip it may not be the clutch.

    I think you have your work cut out for you! I, too, have only worked with 70-90 A material (on a lathe) and it is not much fun. I rough with carbide and finish with files and grinding. The stuff...

    As mentioned above, the lathe model would be helpful. I you don't have that, a picture. Is it geared-head or belt drive?

    Usually, if the feed slips on a Sheldon it is because of a missing or...

    Sure, but he's talking about 'a few graduations' on a precision level. A residential floor tilting prior to imminent failure would be much more than that. You go ahead and spread your limitless...

    If the bubbles move 'in unison', or nearly so, it won't matter anyway. The bed will still be flat. If walking back and forth in the normal work area causes differential movement in the indications,...

    Well, do something. I pulled my well pump a few years ago from 120' because it wasn't performing. Found the intake screen had failed, and inside, riding on the impeller was a nearly perfectly...

    Yeah, and 90% of yours are nothing but disparaging others. But hey, you've got the count up.

    Well, I don't know if its me going crazy or something else, but this thread shows post #1 from MrWhoopie, not the original question about babbit bearings from mpoore:

    I agree that it is something about the VFD. I posted in response to GregSY's comments in post 9, inferring that quick reverse in and of itself is detrimental.

    Yes, and the OP said in his original post that he was leaning that direction



    Ah, the question is finally answered.

    Bullshit. He asked a specific question and none of the exalted experts here deigned to answer. What? They (you) couldn't understand the question? Babbit bearings can still be found in heavy industry...

    I guess I've been lucky. I 'instant reverse' my lathe (1975 Sheldon) at least a hundred times on a busy day for over 15 years. No issues yet. I don't use a VFD though, just the drum switch. Actually...

    Howdy Bill,
    Nope. The ground lead was hanging on the lead rack on the welding cart, 15ft away. I also thought the welding leads would be isolated, but maybe the inverter types are different?

    The model number for your lathe would start with 'E'. The next letter depends on the swing, i.e. a 13" lathe would be 'M'. The next part is the length of the bed, in inches and measured from one...

    Perfect. No doubt you know already, but for others the 40deg rise rating refers to an ambient temp of 40C + typical temp rise for the motor at full load. It is not uncommon for the windings to...

    At that speed, I don't see the chain being any more relevant than the jaws. Just have to pay attention.

    Not seeing your pics. When you say 'connects the spindle to the. . .' are you referring to the fwd/rev toggle gears? All of the gears in the train connect the spindle to the auto drive, but the...

    To be clear, I can't do that kind of work, but I my first thought was about double what you charged. I'd say the customer got his money's worth for a short run.



    Of course! And I'd like to pay...
