Hi Dave,
I have discovered that 3/16 will telescope into 1/4 and 1/4 will telescope 
into 3/8.
I then sweat solder the coupling. However, evidently the tubing comes in 
different
gauges and I have run into some where things aren't that easy. Also, the 
tubing cutter
has a tendency to constrict the opening. In either case a little swaging will 
bring the two
sizes together. Another method is to poke a piece of solid copper wire into 
the two 
pieces, have everything nice and clean and sweat solder the joint. Any piece 
of copper or brass rod giving a close fit to the internal diameter will work 
great.

Cheers,
Ralph Zekelman
