You could use a water level which is a long tube filled with water and a sensor at one end, mine beeps when the water is level. You hold or tack the sensor end at the height you want to level to. You then take the free end of the tube, walk it over to the other fence post, and move it up and down until the sensor starts beeping. Where that water line is, you are level. OK, I didn't due this as it required vision, so Teresa did it for me.
If the fence posts aren't too far apart, you could tack one end of a long board to one post at the proper height, then put an audible level on the board and swing the free end up and down against the next post until the level beeps. Then mark or clamp and you are good to go. -- Blue skies. Dan Rossi Carnegie Mellon University. E-Mail: [email protected] Tel: (412) 268-9081
