The fork that I clamped the 2x4 to was a Schwinn flat bladed fork, so in my case it was easy. On a tubular fork, I don't know. Anything to increase the leverage that might slip over one of the legs. I tried to bend my fork without using the 2x4, and it was possible, but much more difficult to control the bend. With a tubular fork, I'd imagine that the extra leverage would be a must have. Any way you go, it's a crap shoot and you risk irreparable frame/fork damage, so go slow. Also in my case the legs were bent to the side, so you may have to come up with your own ideas for forward bends. I've sucessfully bent a steer tube back into place, but never individual fork legs.
