Wow, fantastic posts guys. Many thanks!

The thing that worries me about using copper pipes is not being able to
heat the joint all the way around due to confined spaces under the floor
boards.

Thanks again guys.

Get a piece of thin metal about 12" x 8" and bend it to a curve so that it
fits about 3" behind the joint you're soldering. This will protect the
surrounding area and will also reflect the heat of the blowlamp back onto
the back of the joint. Reflecting the heat back is less important than
protecting the surrounding area from accidental damage.

Make sure that the bit of metal is soft enough to bend by hand (so that
you
can adjust for different situations) but strong enough to keep its shape
when in use.
