fitting a grease nipple

 not so meny about nowdays

 
  it was just a small mod but i was happy to do it.
 i had already cleaned and fitted the bearing to shaft and had packed it with grease.
 i had to strip it down again to drill and tap the hole.
  then clean again to get all the swarf out.
   sum trailer hubs come with a nipple.  but this was a car hub.
  there easey to do .thay got a taper thread on nipple .
  i already had the tap . in this case it was 1/8" bsp. British standard pipe.
  that imperial.""  but dont know what tap you might use elswhare.
  made sure it was clean then put it all back together .and then pumped in sum fresh grease .  the seals i have arent a good fit .so i did expect a bit dirt on the outside.
  but now i can pump out dirty grease with fresh stuff.

  all i got to do now is train the wife to climb mast with a grease gun .
  and give it a few shots.  ill just tell her the washing machine will get the clothes
 cleaner if she dos that.  she knows  the wind gen will make electric and washing machine
  needs electric .
 yes the tap has a slight taiper  i forgot to say .
 i knew one day they will come in handy.(nipples)
 i suppose its possible to fit one to the yaw tube that fits over pipe.

What you call a 'nipple' is technically named a 'Zerk Fitting'.  Most grease guns are made to support zerk fittings.

i was wondering whether we would get an american translation.  Here in the UK we call them grease nipples.  We also talk about 'swarf' but I was told that this word is hilarious in the states and has no meaning whatsoever there.   For those who might wonder, swarf is the little sharp spirally bits of metal that come off a drill or tap when cutting and threading holes. (Also made by lathes etc.)

Most hubs have the grease nipple/zerk on the bearing stub which goes right into the middle of the alternator and is inaccessible.  Yours looks easier to get at.

You would be surprised how many folk don't have a clue on setting a grease /zerk/nipple/fitting.

Were you really going  to have your work cut out is in wife training wish you luck : )

Hugh

I don't know who you were talking to or where they were from in the US

But all the old school machinist I know me included know what swarf is.

Some call lathe turnings chips but I don't know how well they would go with fish.

Got to go have to smack a young sparks with a spanner for wiring the bond to earth  on a inverter  : )

I've heard them called "shavings", "turnings" and "chips".  But my close-up-and-personal experience with machinists is small since shop class almost half a century ago.  (Electrodynamic machine tool programming doesn't get you involved with people talking about the details of operating mechanical cutters.)

scoraigwind,

actually swarf (in the US) can refer to the slag left behind when cutting steel with a plasma or oxy-acetylene torch.

I cut gemstones and swarf is the ground stone leftovers usually taking the form of a mud since all cutting is done with a lubricant.

 well i dident give much thought when i posted this.
 and now i find it more interesting. a Zerk fitting.
   but so meny scoop viewers looked at this post it must have been the word nipple
 that got there attention .
  so finding out a bit more i see the same thing in the USA is 1/8" NPT.
  thats  NATIONAL PIPE THREAD   .it also looks like the tap can be strait and the zerk
 fitting can have the taper.
 looking in my SKF book it says BSP 1/8" 28 threads
    American national taper pipe 1/8" 27 threads .
  so with only one thread difference .ie 27 and 28. i suppose you can just screw it up tight and will be ok. maybe not for the space shuttle . but hub on a wind gen should be ok.
  but its so lucky i got two nipples on my dinghy trailer.
  PS  A BIG HAPPY BURNS NIGHT up there at scoriage  and to all the other jocks
 who maybe reading this.
  well i may aswell say HAPPY BURNS NIGHT TO ALL.  
its a ill wind that dos no good

From what I gather, swarf is an old woodworkers term. I guess loosely it could be said that all sawdust is swarf, but I have always heard the term referred to hand saws. As in "the handsaw teeth shears the wood fibers and the rakers pull out the swarf"

As a machinist, I have heard the term swarf a lot. In fact I was surprised when another machinist at work took the time to point this out to me. Pointing to a owners manual of our milling machine he said "you can tell this thing was made in China, they call the chips swarf." That was when I had to tell him that swarf was a very old term, both in metalworking and woodworking. It also crosses many borders apparently.

Not that I'm any sort of an expert, but to me "swarf" is all those nasty twisty spiky metal bits you get when machining that would hook into your skin and take your eye out as soon as laugh at you.  Wood splinters (etc) just aren't in the same ballgame IMHO...
