Radiator and iron pipe update. Fairly ugly.

[Filliam H. Muffman]

I don't know if you will be able to easily thread the cut iron pipe, but I guess it's possible. It depends on how far you can pull it up through the floor. I would be more tempted to measure it for length down to the next joint, and then replace that section with a pre-threaded pipe of the right length.

Please post when you get it working.
