[Steam-engine] Lunk Jr.

[Lawrence Swanz]

Rick,

I can't hardly believe that the before picture could actually be the same lubricator as pictured in the second photo.  If they are the same, then you did an outstanding job cleaning that unit up.  As for the glass, I would say that a 5/8" O.D. tube is the ticket.  Don't know about whether to put a wrench to the packing nut is acceptable or not, but if you had to stop any leaks, and I'm sure this goes without say, but be darn careful as to not over tighten and crack the glass.  I watched someone do this on a water glass and didn't find that magic spot.  It wasn't long and the glass exploded and they did the jump of joy on the gang plate as they tried to get the valves shut off while being sprayed with hot steamy water.  Guess this is another good argument for replacing your water column with a new style that has a ball bearing in it for self sealing should the glass break.  That is yet for another discussion.  On a side note, I liked the white socks that got caught in the photo.  You had them there so we could identify actual size of the lubricator, right! (Haa Haa).

Hi Andy and thanks for the reply!

Here's our Lunk Jr.  You can see where the replacement glass tube will go:

http://community.webshots.com/photo/188300547/1475450142039077051MWyQdB

  This is a round tube like a water gauge.

  OEM was .710 OD.  .750 will fit but there's no room/gap for the "V" 
packing to fit or compress into.  Now I'm thinking of using 5/8 OD, (not the 
9/16's that I'd previously mentioned.)  5/8's will give me ~ 1/16th inch gap 
for the packing.

   Recently I read that no wrenches should be used on the packing nut and 
that the glass should not contact the metal, the packing acts as a cushion 
also.  This makes sense to me regarding the circumference, not so sure they 
mean the ends of the glass, but will try to avoid that also.

Best Regards,
RickinMt.
