I'am building a arched bridge,using 2x2's for handrails. How can I contour the rails to the same arch as the bridge? I'm a real novice at this! My thoughts are nailing the rails to the bridge deck temporarly to form them.

Is there some way to use water and/or heat to speed the process?
These are 8 foot in length,I don't have a way of completely immersing them in water. They are treated also.

If anyone has any ideas on this please help.

Thank You
