Step by step instructions to pull 240 volts from my panel? Have wired in new breakers before 15amp, 20amp, all for 120 never 240.

Step by step? That could be quite a bit of typing, let's be fair and you ask exactly what your not sure about and someone can go from there.

You may have it down already and not realized what you know. If you have done single pole breakers, all a 240 volt circuit is a 2 pole breaker, to which you connect two wires to, which could be a black and white (relabel the white with black tape to indicate the white is now being used as a hot), or a black and red from a 3 wire cable, such as one to feed a range or dryer.

A single pole uses only one wire to the breaker, but the white(neutral) connects to the neutral bar.

See how much typing just to connect two wires? See if this helps, and get back with specifics of what your not sure about.
