Re: Spindle bearing replacement

What is the specified runout for the P5 bearings? What runout do you actually need?

Re: Which grease to replace old specification?

Yep! That's what I know from just recently having investigated the proper gear lube to use in the muller I rebuilt. Because it has a bronze gear, modern lubricants can't be used, as they dissolve copper alloys. Older hypoid gear lube is acceptable, and that's what I chose to use. H I recently inves...

Re: Damaged chuck - a forensic investigation

Had a crash, then damaged further pounding on it to get it to release?

Regulations aside, how do you plan to enter and exit the pipe air tight?
I assume that he wants to fish an air line through the conduit alongside the electrical conductors. I doubt that the conduit is air tight.

Re: Bare Metal Protection

Glue one of these to the underside of the ways of your lathe and another somewhere low down on your mill:

Re: Which grease to replace old specification?

While this is probably true in some sense, it does not follow that every modern grease is a suitable replacement for every grease that was available in the past. You wouldn't pack a ...

Re: Thieves caught on video stealing mini steam train in West Seattle

Pretty sad. Obviously they knew it was there and had the theft planned. On the brighter side (if you can call it that) Its doubtful that they just stole it for scrap metal, so hopefully it shows back up as a complete engine. Or all they knew was that "Those things are worth a lot of money" and when...

Re: Help me Change a Kubota Quick Coupler

There are a number of these fittings that look superficially like NPT and will seem to interoperate. On old farm machinery I frequently discover instances of an NPT pipe fitting having been substituted for the correct hydraulic fitting (I've done it myself, actually). Sometimes it works, given enoug...

Re: Help me Change a Kubota Quick Coupler

If the nipple has threads that look like NPT it's actually NPTF Dryseal. If you replace it with an NPT nipple it is likely to leak.

Re: Damaged chuck - a forensic investigation

Two slots are damaged.

Another guess: the jaws were backed way out, something was clamped only with the tips of the jaws, and then the chuck was tightened with a monkey wrench on the key.

In any case, I'd follow John's advice. Check the spindle, too.

Re: Engine Cleaner (exterior)

Delete the message if it offends you. I did not mean to recommend the use of gasoline for cleaning, just to describe some safety precautions should one choose to do so. BTW I didn't intend to say that mineral spirits were excessively expensive, just to note that there is no point in paying an exorbi...
