Metalworking, resizing copper tubing-
I measured the tubing and reads around .655", about .030" too big. I was
able to taper the end of the copper and hammer the compression nut onto the
tubing, this "sized" the tubing enough to get the compression sleeve on and
I got the valve on the line, but I would like to fix it better later.
I could either shrink the tubing down to .625" or expand to solder a
correctly sized tubing inside the end of the old tubing.
Could you bore out one side of a coupling, and add a short length of
the proper sized tubing? Hmm, .030 is probably too much for a common
coupling to be bored out. Could you make a coupling(f/m adaptor?)
from a piece of brass?
Just get some emery cloth and sand down the outside of the pipe a wee
bit and solder a 5/8 to 1/5 adapter on. Might need to heat the adapter
a bit - copper grows significantly when heated.
I'm ASSuming the 5.8" tubing is "soft" copper??? Most "hard" copper is
1/2 or 3/4".
