Harness Machine Fab 3/8" AR500 Steel DIY Dueling Tree Kit. Includes (6) 8” dueling tree paddles (6) 4”X 1.25" X 1/8" wall Dom pivot tubes (Much better than cheap ERW pipe used in other kits, as there is no weld and tubes allow paddles to swing freely.) Assembly is required!!! This is a kit, not an entire dueling tree. You will need other materials and welding and fabricating capabilities. Fabricate a base and upright 1.5" x .25" angle iron is recommended IMPORTANT!!!! Make sure DOM pivot tubes are welded a MINIMUM of 6" apart. Any less and the paddles won't be able to be removed.
