[Shop-talk] I'm tired of oil talk... lets talk plumbing

[Karl Vacek]

But cutting out a section and gluing in a new piece is simple - just use 
non-stopped couplings.  They slide completely over the pipe and get out of 
the way.  That gives you telescoping and doesn't require exotic proprietary 
parts - just cheap old PVC.

Put the couplings onto the pipe (primed but dry of glue), drop the pipe in 
place, slobber lots of glue on it, and slide the couplings into place. 
Maybe push each coupling a little too far and add some more glue at the 
railing edge too, then slide it back to the center of the joint.  Just 
remember to mark the positions for the couplings to get them centered over 
the joint.

Works even easier with copper, since there's no glue to worry about and you 
can play with it all day till you're ready to solder it.
